Description

  The present invention relates to a soft ground determination device, a soft ground determination method, and a soft ground determination program, and more particularly to a soft ground determination device, a soft ground determination method, and a soft ground determination program that determine whether or not the ground is soft ground.

  The phenomenon that buildings are unevenly subsidized (sinks that tilt diagonally in one direction, rather than the entire home sinking equally) is called non-uniform subsidence. If a dissimilar settlement occurs, the building will be heavily damaged. It is known that uneven settlement occurs on soft ground. Therefore, ground surveys are important when building buildings. However, ground surveys are expensive and time consuming, and it is a heavy burden to carry out all land surveys.

  For example, the soft ground may be known to some extent from closed copies and past maps. Patent Document 1 describes a technique for storing land separation / integration information by date and change information and displaying a land shape for each date and time. As described above, a map of a house at a certain time can be created from a change in land, a change in coordinate information of the house, or the like.

When building a building, in the past, in order to reduce the burden of ground investigation, soft ground was estimated from closed copies and past maps.

(Information update process necessary for real estate registration)
FIG. 4 is a block diagram for explaining an update process of information necessary for real estate registration of the system for determining the soft ground. FIG. 5 is a flowchart showing an update process of information necessary for real estate registration of the system for determining soft ground. 4 and 5, an update process at the time of drawing is described as an example of an update process of information necessary for real estate registration.

  Proceeding to step S1, for example, the target lot number input means 31 of the terminal 3 in the registry office designates a lot number area to be divided by the user. Proceeding to step S2, the dividing means 32 of the registration processing device 21 included in the map information system 2 provides a UI necessary for the dividing to the terminal 3, and performs the map correction process at the time of map drawing based on the information input from the user. carry out. Steps S1 and S2 are existing processes. The registry map DB 23, the land survey map DB 24, and the building drawing DB 25 are updated by the process of step S2.

  FIG. 6 is a configuration diagram of an example of a registry map DB. FIG. 7 is a configuration diagram of an example of the land survey map DB. FIG. 8 is a configuration diagram of an example of a building drawing DB.

  The registry map DB 23 in FIG. 6 is configured to include a connection table, a coordinate value table, and a brush attribute table. 7 is configured to include a connection table, a coordinate value table, and an attribute table. Further, the building drawing DB 25 in FIG. 8 is configured to have a connection table, a coordinate value table, and an attribute table. The details of each table included in the registry map DB 23, the land survey map DB 24, and the building drawing DB 25 are already existing, and the description thereof will be omitted.

  When the registry map DB 23, the land survey map DB 24, and the building drawing DB 25 are updated in step S2, the root cutting table correction means 33 of the soft ground determination device 22 proceeds to step S3 and uses a building figure as shown in FIG. Then, it is determined whether or not there is an intersection between the building figure (1F) and the dividing line. FIG. 9 is an image diagram of an example of a building drawing including a building figure. A building figure is a figure which shows the place of the house entered in the brush figure as shown in FIG. FIG. 10 is an image diagram of an example of a brush drawing including a brush figure.

  If there is an intersection between the building figure (1F) and the dividing line, the root cutting table correcting means 33 proceeds to step S4, and performs registration processing in the root cutting figure table of the root cutting DB 26 shown in FIG. FIG. 11 is a configuration diagram of an example of the root cutting DB. The root cut DB 26 in FIG. 11 is configured to have a root cut figure table, a root cut figure coordinate value table, and a root cut figure connection table.

  The root cut graphic table has a lot number, a SEQ, a house number, a valid flag, a glass flag, a pre-change SEQ, and a building lost date as items. The root cut figure coordinate value table is configured to have a point number, a coordinate value X1, and a coordinate value Y1 as items. The root cutting figure connection table has SEQ, registration date, point number 1 and point number 2 as items.

  The item “lot number” is for identifying the lot number. The item “SEQ” is for identifying a record. The item “house number” is for identifying a house. The item “valid flag” is for identifying the latest record. The item “Gala possibility flag” indicates that there is a high possibility that the glass is buried. The item “SEQ before change” is for associating with the record before update. The item “building lost date” is for setting a building lost date by building loss registration.

  Further, the root cut figure coordinate value table and the root cut figure connection table have points for drawing a root cut figure as shown in FIG. 12 and information for connecting the points. FIG. 12 is an image diagram of an example of a rooting drawing including a rooting figure. The root cut graphic is a graphic showing the location of the root cut written on the brush graphic as shown in FIG. Here, root cutting refers to excavating the ground when building a building (or when demolishing a building) to create (or break) the foundation of the building.

  Specifically, if there is an intersection between the building graphic and the stroke line, the root cutting table correcting means 33 divides the root cutting graphic in accordance with the stroke line. The root cutting table correcting means 33 registers the information of the divided root cutting figures in the root cutting figure table. The root cutting table correcting means 33 uses the value of the item “SEQ” of the record of the root cutting figure table indicating the information of the root cutting figure before the division as the value of the record of the root cutting figure table indicating the information of the root cutting figure after the division. Set the item “SEQ before change”.

  Proceeding to step S5, the root cutting table correcting means 33 registers the coordinate value of a new point associated with the division of the root cutting graphic in the root cutting graphic coordinate value table of the root cutting DB 26 of FIG. In step S6, the root cutting table correcting unit 33 registers new connection information associated with the division of the root cutting graphic in the root cutting graphic connection table of the root cutting DB 26 of FIG. The root cutting table correction means 33 proceeds to step S7 after the process of step S6. Even if there is no intersection between the building figure and the stroke line in step S3, the root cutting table correcting means 33 proceeds to step S7.

  In step S7, the root cutting table correcting means 33 determines whether or not the building figure of the 1F part of the submitted building drawing is the same as the building figure of the 1F part of the managed building drawing. If the building figure of the 1F portion of the submitted building drawing is not the same as the building figure of the 1F portion of the managed building drawing, the root cutting table correcting means 33 proceeds to step S8 and based on the new building drawing. A new root cutting figure is created and registered in the root cutting figure table.

  Proceeding to step S9, the root cutting table correcting means 33 registers the coordinate value of a new point associated with the new root cutting graphic in the root cutting graphic coordinate value table of the root cutting DB 26 of FIG. In step S10, the root cutting table correcting unit 33 registers new connection information associated with the new root cutting graphic in the root cutting graphic connection table of the root cutting DB 26 of FIG. The root cutting table correcting means 33 proceeds to step S11 after the process of step S10.

  In step S7, also when the building figure of the 1F part of the submitted building drawing is the same as the building figure of the 1F part of the managed building drawing, the root cutting table correcting means 33 proceeds to step S11. In step S11, the root cutting table correcting means 33 determines whether the building is lost or not.

  If it is a building loss registration, the root cutting table correcting means 33 proceeds to step S12, sets the building lost date in the item “building lost date” of the root cutting graphic table of FIG. 11, and then performs the processing of the flowchart shown in FIG. Exit. In step S11, the root cutting table correcting means 33 also ends the process of the flowchart shown in FIG.

(Update processing of information necessary to determine soft ground)
FIG. 13 is a block diagram for explaining an update process of information necessary for determining the soft ground of the system for determining the soft ground. FIG. 14 is a flowchart showing an update process of information necessary for determining the soft ground of the system for determining the soft ground.

  Proceeding to step S21, for example, the coordinate value input means 41 of the terminal 3 in the registry office receives the coordinate value of the spot where the glass has been found by the ground survey from the user. The coordinate value input means 41 notifies the input coordinate values to the root cutting table information extraction / update means 42 of the soft ground determination device 22 included in the map information system 2. The root cutting table information extracting / updating means 42 included in the map information system 2 provides the terminal 3 with a UI necessary for updating information necessary for determining the soft ground. Then, the root cutting table information extracting / updating means 42 is notified of the ground survey result from the terminal 3.

  Proceeding to step S22, the root cutting table information extracting / updating means 42 corresponds to the coordinate value notified in step S21 and the item “valid flag” is “valid” (shows a certain root cutting figure). The latest record) is extracted from the rooted figure table shown in FIG.

  Proceeding to step S23, the root cutting table information extracting / updating means 42 sets the result of the ground investigation in the item “garbability flag” of the latest record extracted at step S22. The root cutting table information extracting / updating means 42 proceeds to step S24, and saves the ground investigation result (set value of the possibility flag) set in step S23.

  Proceeding to step S25, the root cutting table information extracting / updating means 42 retrieves the parent record from the rooting drawing table based on the item “pre-change SEQ” of the latest record extracted at step S22.

  Proceeding to step S26, the root cutting table information extracting / updating means 42 sets the ground investigation result saved in step S24 (set value of the possibility flag) in the parent record extracted by the search in step S25.

  In step S27, the rooting table information extraction / update unit 42 determines whether the setting value of the item “SEQ before change” of the parent record extracted by the search in step S25 is “initial”. If the setting value of the item “SEQ before change” of the parent record extracted by the search in step S25 is not “initial”, the rooting table information extracting / updating means 42 returns to step S25 and extracted by the search in the previous step S25. Based on the set value of the item “SEQ before change” of the parent record, a further parent record is searched from the root drawing table.

  Then, the root cutting table information extracting / updating means 42 performs the processes of steps S26 and S27 described above. The processing in steps S25 to S27 is repeated until the setting value of the item “SEQ before change” of the parent record extracted by the search in step S25 is determined to be “initial”. If the setting value of the item “SEQ before change” of the parent record extracted by the search in step S25 is “initial”, the rooting table information extracting / updating means 42 ends the processing of the flowchart shown in FIG.

(Decision processing of soft ground)
FIG. 15 is a block configuration diagram for explaining soft ground determination processing of the system for determining soft ground. FIG. 16 is a flowchart showing the soft ground determination process of the system for determining soft ground.

  Proceeding to step S31, for example, the target lot number input means 51 of the terminal 3 in the registry office is designated by the user as a lot number area to be determined for soft ground. Step S31 is an existing process.

  In step S32, the map figure table / root cutting table information extraction means 52 of the soft ground determination device 22 included in the map information system 2 provides the UI necessary for determination of the soft ground to the terminal 3, and outputs the past to the user. Specify the number of maps (number of past maps). Details of the number of past maps to be output will be described later.

  Proceeding to step S33, the map graphic table / rooting table information extracting means 52 extracts a record in which the item “valid flag” is “valid” from the connection table of the registry map DB 23 shown in FIG.

  In step S34, the map graphic table / root cutting table information extracting unit 52 extracts a record in which the item “valid flag” is “valid” from the root cutting graphic table of the root cutting DB 26 shown in FIG. The root cut figure indicated by is extracted.

  The map graphic table / root cutting table information extraction unit 52 extracts a record corresponding to the extracted root cutting figure from the root cutting figure connection table of the root cutting DB 26 shown in FIG. Proceeding to step S35, the map output means 53 outputs a map using the registry map DB 23, the land survey map DB 24, the building drawing DB 25, and the root cut DB 26 as appropriate based on the records extracted in steps S33 and S34. .

  In step S36, the map graphic table / rooting table information extraction unit 52 searches the latest record from the registered article management list as shown in FIG. 17, and sets the item “registration date” of the record extracted by the search. Save the value. FIG. 17 is a configuration diagram of an example of the registered article management list.

  In step S37, the map graphic table / root cutting table information extracting means 52 has records in the connection table of the registry map DB 23 shown in FIG. 6 and the root cutting graphic connection table of the root cutting DB 26 shown in FIG. It is determined whether the number of past maps is greater than zero.

  If there is a record in the connection table of the registry map DB 23 shown in FIG. 6 and the root cutting figure connection table of the root cutting DB 26 shown in FIG. 11 and the past number of maps is larger than 0, the map figure table / root cutting table information. The extraction means 52 proceeds to step S38. In step S38, the map figure table / rooting table information extraction means 52 stores the latest record among the records older than the registration date saved in step S36 from the connection table of the registry map DB 23 shown in FIG. To extract.

  In step S39, the map graphic table / rooting table information extracting unit 52 extracts a record having the same setting value of the item “registration date” from the rooting graphic connection table of the rooting DB 26 as the record extracted in step S38. Extract. In step S40, the map output means 53 outputs a map using the registry map DB 23, the land survey map DB 24, the building drawing DB 25, and the root cut DB 26 as appropriate based on the records extracted in steps S38 and S39. .

  In step S41, the map graphic table / rooting table information extraction unit 52 saves the set value of the item “registration date” in the record extracted in step S38. Proceeding to step S42, the map graphic table / root cutting table information extracting means 52 subtracts 1 from the number of past maps, and then returns to the processing of step S37.

  The processing of steps S37 to S42 is repeated until there is no record in the connection table of the registry map DB 23 shown in FIG. 6 and the root cutting figure connection table of the root cutting DB 26 shown in FIG. Done.

  Note that if there is no record in the connection table of the registry map DB 23 shown in FIG. 6 and the root cutting figure connection table of the root cutting DB 26 shown in FIG. The table information extraction unit 52 ends the process of the flowchart of FIG. By the processing of the flowchart of FIG. 6, the soft ground determination device 22 outputs a soft ground determination map 54 described later.

  Here, an example in which the target district has changed as shown in FIG. 18 will be described. FIG. 18 is an image diagram showing the transition of the map of the target area. As shown in FIG. 18, it is assumed that the lot number “10” in 1960 was a large residential land where the building “K01” was built. In 1980, the building “K01” was demolished, the lot number “10” in 1960 was drawn, and the building numbers “10” and “11” where the building “K10” and the building “K20” were built became residential land. Assume. Assume that the building “K10” was demolished in 1995, the lot number “10” in 1980 was drawn, and the lot numbers “10” and “12” became residential land.

  In 2007, the building “K20” was demolished, and the lot numbers “11” and “12” in 1995 were separated, and the lot numbers separated from the lot numbers “11” and “12” in 1995 were combined. Assume that the housing lots of lot number “10”, lot number “11”, lot number “12”, and lot number “20” have been obtained. Note that a building “K40” and a building “K30” are built at the lot number “10” and the lot number “11”.

  FIG. 19 is a configuration diagram showing the transition of the registry map DB from 1960 to 1980. In FIG. 19, the upper side represents the registry map DB 23 of 1960, and the lower side represents the registry map DB 23 of 1980. In 1980, the lot number “10” of 1960 was drawn, and the lot number “10” and the lot number “11” became residential land. Therefore, the shaded records of the lower registry map DB 23 are displayed in the upper registry map DB 23. Have been added. The transition of the registry map DB 23 shown in FIG. 19 is performed by step S2 of FIG.

  FIG. 20 is a configuration diagram showing the transition of the land survey map DB from 1960 to 1980. In FIG. 20, the upper side represents the 1960 year land area survey map DB 24, and the lower side represents the 1980 year land area survey map DB 24. In 1980, the lot number “10” of 1960 was drawn, and the lot number “10” and the lot number “11” became residential land. Therefore, the shaded records of the lower registry map DB 23 are displayed in the upper registry map DB 23. Have been added. Transition of the land surveying DB 24 shown in FIG. 20 is performed by step S2 of FIG.

  FIG. 21 is a configuration diagram showing the transition of the rooting DB from 1960 to 1980. In FIG. 21, the upper side represents the 1960 root cutting DB 26, and the lower side represents the 1980 root cutting DB 26.

  In 1980, the lot number “10” in 1960 was drawn, so there is an intersection between the line “t14-t15” of the lot number “10” and the building figure of the building “K01” of the lot number “10”. Determined. In the example of FIG. 18, since there is an intersection, the setting value of the item “valid flag” of the record representing the information of the rooting figure before division in the rooting figure table of the lower rooting DB 26 is changed from “valid” to “invalid”. To be corrected.

  In order to divide the root cutting figure in accordance with the stroke line “t14-t15”, a shaded record for representing information of the divided root cutting figure is added to the lower root cutting DB 26. In the lower rooting figure table, the record item “SEQ before change” indicating the information of the rooting figure after the division is set as the set value “SEQ” of the record item “SEQ” indicating the information of the rooting figure before the division. 10.1 "is set. The transition of the root cutting DB 26 shown in FIG. 21 is performed by steps S3 to S6 in FIG.

  FIG. 22 is a configuration diagram showing the transition of the root cut DB when the building is changed by another registration process. In 1980, it is determined whether the building figure of the 1F part of the submitted building drawing is the same as the building figure of the 1F part of the managed building drawing.

  In the example of FIG. 18, the building figure of the 1F portion of the buildings “K10” and “K20” in the submitted building drawing is different from the building figure of the 1F portion of the building “K01” in the managed building drawing. Based on the building drawings thus created, new root cutting figures corresponding to the buildings “K10” and “K20” are created and registered in the root cutting figure table. Note that the setting value of the item “valid flag” in the record of the rooting figure table corresponding to the building “K01” in the managed building drawing is corrected from “valid” to “invalid”. In addition, a shaded record is added to the root cut figure coordinate value table and the root cut figure connection table in order to register coordinate values and connection information of new points associated with the new root cut figure. The transition of the root cutting DB 26 shown in FIG. 22 is performed by steps S7 to S10 in FIG.

  FIG. 23 is a configuration diagram showing the transition of the root cut DB when the building loss registration is performed. In 1980, it is determined whether a building loss registration has been submitted. Here, it is assumed that the building loss registration of the building “K01” has been submitted. Since the building loss registration of the building “K01” has been submitted, the building loss date is set in the item “building lost date” of the record corresponding to the building “K01” in the rooting graphic table. The transition of the root cutting DB 26 shown in FIG. 23 is performed by steps S11 to S12 in FIG. When the processes shown in FIGS. 19 to 23 are performed until 2007, the root cutting DB 26 becomes as shown in FIG. FIG. 24 is a configuration diagram of an example of a rooting DB as of 2007.

  FIG. 25 is an image diagram for explaining the information update process during the ground survey. The mark “◎” in FIG. 25 represents a point where there was no problem as a result of the ground survey. The mark “★” indicates a point where there was a problem, for example, a gala was found as a result of ground survey.

  For example, the user inputs a coordinate value of a point having a problem or a point having no problem by a ground survey from the terminal 3 in the registry office. The input coordinate value of the problematic point or the problematic point is notified to the soft ground determination device 22.

  The soft ground determination device 22 extracts a record including coordinate values of a point having a problem or a point having no problem input by the user, in which the item “valid flag” is valid, from the rooting figure table.

  The soft ground determination device 22 sets a flag indicating that there is a problem or a flag indicating that there is no problem in the item “Gala possibility flag” of the record extracted from the root cut graphic table as shown in FIG. FIG. 26 is a configuration diagram of an example of a rooting figure table in which the item “Gala possibility flag” is set.

  26, the item “SEQ” is set to “No problem” in the item “Gala possibility flag” of the record whose item “SEQ” is “12.2”, and the item “SEQ” is set to “20.2”. “Problem” is set in the item “Gala possibility flag”.

  Next, the soft ground determination device 22 searches the root cutting drawing table for the parent record based on the item “SEQ before change” of the record extracted from the root cutting graphic table. For example, in the case of the rooted figure table of FIG. 26, the record whose item “SEQ” is “12.1” is extracted based on the item “SEQ before change” of the record whose item “SEQ” is “12.2”. Then, based on the item “SEQ before change” of the record whose item “SEQ” is “20.2”, the record whose item “SEQ” is “11.2” is extracted.

  For example, the extracted item “SEQ” is “12.1” in the item “Gala possibility flag”, and the item “SEQ” that is a child record is “12.2” in the item “Gala possibility flag”. Set the same setting value as “No problem”.

  The extracted item “SEQ” is “11.2” in the item “Gala possibility flag” of the record, and the item “SEQ” that is a child record is “20.2” in the item “Gala possibility flag”. Set the same setting value “Problem”.

  The soft ground determination device 22 repeats the above process until the item “SEQ before change” of the record extracted from the root cut graphic table becomes “initial”. As a result of the above processing, if there is a parent record that has multiple child records and the setting value of the item “Gala possibility flag” of the child record is different, set it to the item “Gala possibility flag” of the parent record Set the value "Unknown".

  26 is updated as shown in FIG. 27 by repeating the above process until the item “SEQ before change” of the record extracted from the root cut graphic table is “initial”. FIG. 27 is a configuration diagram of an example of a root cut graphic table updated with information at the time of ground investigation. Note that the update of the rooting figure table shown in FIGS. 25 to 27 is performed according to the procedure shown in the flowchart of FIG.

  FIG. 28 is an image diagram of an example of a soft ground determination map that can be output by the soft ground determination processing. For example, the user inputs a lot number to be subjected to soft ground determination from the terminal 3 at the registry office. The input lot number is notified to the soft ground determination device 22. Further, the soft ground determination device 22 provides the UI to the terminal 3 and causes the user to specify the number of past maps to be output (the number of past maps).

  The number of past maps is the number of past maps included in the soft ground determination map 54 shown in FIG. 28. In the case of FIG. 28, the map of 2007, the map of 1995, the map of 1980, and the map of 1960 4 maps.

  Next, the soft ground determination device 22 extracts a record in which the item “valid flag” is “valid” from the connection table of the registry map DB 23. Further, the soft ground determination device 22 extracts a record in which the item “valid flag” is “valid” from the root cut graphic table of the root cut DB 26 illustrated in FIG. 27, and extracts the root cut graphic indicated by the extracted record.

  The soft ground determination device 22 extracts a record corresponding to the extracted root cutting figure from the root cutting figure connection table of the root cutting DB 26 shown in FIG. The soft ground determination device 22 appropriately registers the registry map DB 23, the land survey map DB 24, the building drawing DB 25, and the root based on the records extracted from the connection table of the registry map DB 23 and the root cutting graphic connection table of the root cutting DB 26. A map of 2007 is output using the cut DB 26.

  As a result of the ground survey in FIG. 28, a mark “◎” indicating a point where there was no problem, a mark “★” indicating a point where there was a problem, such as a spot found as a result of the ground survey, “★”, “ A mark 100 representing a point determined to have no problem (estimated) from a point “◎” and a mark 101 representing a point determined to be problematic (estimated) from a point “★” Display based on the graphic table item “Gala possibility flag”.

  Subsequently, the soft ground determination device 22 searches the latest record in the entry management book as shown in FIG. 17 and saves the set value of the item “registration date” of the record extracted by the search. The soft ground determination device 22 determines whether there is a record in the connection table of the registry map DB 23 shown in FIG. 6 and the root cutting figure connection table of the root cutting DB 26 shown in FIG. .

  If there is a record in the connection table of the registry map DB 23 shown in FIG. 6 and the root cutting graphic connection table of the root cutting DB 26 shown in FIG. 24 and the past number of maps is larger than 0, the soft ground determination device 22 has retreated. Among the records older than the registered date, the latest record is extracted for each lot number from the connection table of the registry map DB 23 shown in FIG.

  Further, the soft ground determination device 22 extracts a record having the same set value of the item “registered date” from the extracted record connection table of the root cut DB 26 as the extracted record. The soft ground judgment device 22 is based on the latest record among records older than the saved registration date extracted from the connection table of the registry map DB 23 and the root cutting figure connection table of the root cutting DB 26. Output a map.

  The soft ground determination device 22 saves the set value of the item “registration date” of the latest record among the records older than the saved registration date, and subtracts 1 from the number of past maps. The soft ground determination device 22 does not have a record in the connection table of the registry map DB 23 shown in FIG. 6 and the root cutting figure connection table of the root cutting DB 26 shown in FIG. Repeat until.

  If the above process is repeated until there is no record in the connection table of the registry map DB 23 shown in FIG. 6 and the root cutting figure connection table of the root cutting DB 26 shown in FIG. The soft ground determination device 22 can output a soft ground determination map 54 as shown in FIG.

  By outputting the soft ground determination map 54 in FIG. 28, the user can easily estimate, for example, at what point the unscrupulous trader mixed the waste into the backfill soil for root cutting. As described above, the system 1 in FIG. 1 can accurately determine (guess) a point where there is a problem based on the result of the ground survey conducted by another person or the result of the ground survey performed in the vicinity.
