Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial Application Field The present invention relates to a construction management device for drain material casting work.

BACKGROUND OF THE INVENTION Generally, in drain material installation work, it is necessary to constantly check whether the drain material has been driven to the planned depth.

For this reason, conventionally only the length of the drain material unreeled from the reel was detected, and this was displayed and recorded.

In addition, a marking indicating the driving depth is placed on the outer circumference of the mandrel, and by visually checking this, it is determined whether or not the drain material has been driven to a predetermined depth.

Problems to be Solved by the Invention However, by simply detecting the length of the drain material, co-up cannot be confirmed until after the mandrel has been completely pulled out, which requires wasted time and effort until the mandrel is completely pulled out. Ta.

In addition, if the pouring depth is displayed on the mandrel and concrete is placed while visually checking it, not only will there be problems with pouring accuracy, but the display of the pouring depth must be changed each time depending on the degree of softness of the ground. However, this required extra effort.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to identify abnormalities such as joint upwelling of drain material and excessive or insufficient penetration of the mandrel in real time, and immediately retry the operation. The purpose of the present invention is to provide a construction management device that can perform construction work and improve work efficiency.

[Structure of the Invention] Means for Solving the Problems The construction management device for drain material casting work of the present invention is capable of controlling mandrel penetration depth and drain material casting length that change every moment during driving and pulling out of the mandrel. a detection means for continuously detecting the depth of the concrete; a setting means for setting the allowable co-upage amount, design pouring depth, etc.; Calculation means for calculating abnormalities, etc., display means for displaying the mandrel penetration depth, drain material casting length, set casting depth, etc., and mandrel penetration depth, drain material casting length, design casting depth, common uplift amount. and a recording means for recording these totals, etc.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a construction cart which can freely turn and travel on soft ground, and has a boom 2 erected at its front. Sheave 2 at the upper end of the boom 2
A wire rope 3 is wrapped around a, and a driving frame 4 is connected to this. The wire rope 3 is further passed around a lower sheave 5 and wound around a winch 6.

A mandrel 7 is attached to both ends of the driving frame 4.
The upper end of is attached. A reel 8 is installed on the driving frame 4 in correspondence with each mandrel 7. A drain material D is wound around the reel 8, and the drain material D fed out from this passes through the mandrel 7, and its tip is connected to the anchor plate 9 which is in contact with the lower end surface of the mandrel 7. ing.

As is clear from FIG. 3, a drain material casting length detector 10 is installed between the reel 8 and the inlet of the mandrel 7, and is capable of detecting the amount of drain material D pulled out, that is, the casting length. It's getting old.
As the detector 10, for example, a rotary encoder with a resolution of about 1 cm is used, and the reference (0 point) is set at the time when the driving switch described later is pressed, and is added when the reel 8 is fed out and subtracted when rewinding. It's summery. Further, since a moderate tensile force is applied to the drain material D that is fed out by controlling the reel 8, there is no slack, and the casting length of the drain material D can be accurately detected.

11 is also a mandrel penetration amount detector, such as a rotary encoder that can distinguish between forward and reverse rotation and has a resolution of about 1 cm, and is capable of detecting the amount of insertion or withdrawal of the mandrel 7. In addition, when the driving switch is pressed, the detector 11 uses the ground surface as a reference (0 point), the underground side is positive, the ground side is negative, and it adds when driving and subtracts when pulling out. There is.

12 is an arithmetic unit, and the above two detectors 1
Calculations are made using the detection data from 0 and 11 and the setting data preset by the setting section 13, and if there is an abnormality in the co-upward movement of the drain material D or excessive or insufficient penetration of the mandrel, the operator is alerted.

The setting section 13 uses a digital switch or ten key switch 15 provided on the operation panel 14 as shown in FIG. No.,
It is now possible to set the design pouring depth, etc.
Incidentally, once the initial pouring number is set, the pouring number is automatically incremented by +2 each time the mandrel is driven thereafter.

Further, the operation panel 14 is provided with display sections 16. This display section 16 displays numbers using red LEDs so that the operator can easily see them even during the day. The display items include the above-mentioned pouring number, design pouring depth, mandrel penetration depth, left and right drain material pouring lengths, etc.

Furthermore, the operation panel 14 includes a power switch with a pilot lamp, a driving switch that is pressed when the mandrel 7 is set on the ground surface, a pull-out switch that is pressed when driving is completed and pulling begins, and setting items. Record switch to press after setting, change switch to press to change the design pouring depth, conversion switch to press to replace drain material D, design pouring depth, mandrel penetration depth, drain material pouring length, common uplift amount, etc. A total switch, etc. that is pressed when totaling is provided.

Reference numeral 17 denotes a recording section, which is equipped with a pen recorder for recording the mandrel penetration depth and two drain material casting lengths as shown in FIG. 6, and a printer for recording various data.

Next, a drain material casting operation using the construction management apparatus of the above embodiment will be explained.

First, before starting work, enter the pouring date, pouring number, design pouring depth, etc. using the numeric keypad.
The information is displayed on the display section 16 of the operation panel 14, and the construction cart 1 is moved to the initial pouring position.

Next, as shown in FIG. 5A, the drain material D is pulled out a little from the lower end of the mandrel 7, the anchor plate 9 is attached to its tip, and the drain material D is rewound again to the state shown in FIG. 5B. Make it. Then, as shown in FIG. 5C, the lower end of the mandrel 7 is set on the ground surface.

In this state, the mandrel penetration depth on the display section 16 is set to 0, and the driving switch is pressed to drive the mandrel 7 into the ground. When the mandrel 7 is driven in, the mandrel penetration amount detection section 11 counts the penetration amount moment by moment. The data on the mandrel penetration amount is input to the calculation section 12, and is displayed as the mandrel penetration depth on the display section 16 of the operation panel 14, and is further recorded by the pen recorder of the recording section 17 as shown by line segment M in FIG. It will be recorded as follows. If the penetration amount of the mandrel 7 exceeds the design depth or stops before reaching it, this penetration amount data is compared with the design casting depth input in advance, and if the difference exceeds the allowable value, A warning will be issued.

When the mandrel 7 reaches a predetermined penetration depth as shown in FIG. 5D, the pull-out switch is pressed to pull out the mandrel 7. When the mandrel 7 is pulled out and raised, the anchor plate 9 remains in the ground, and as the mandrel 7 rises, the drain material D is pulled out from the lower end of the mandrel 7. When the drain material D is pulled out, the drain material casting length detection section 10 starts counting,
The data is input to the arithmetic section 12 and displayed as the drain material casting length on the display section 16 of the operation panel 14.
The data is recorded by the pen recorder No. 7 as shown by the line segment N in FIG.

Incidentally, while the mandrel 7 is being raised, the mandrel penetration depth is counted as a negative value and displayed on the display section 16 and recorded on the recording section 17 as shown by the line segment L in FIG. 6.

If the drain material D co-rises while the mandrel 7 is being pulled out, this information is input to the calculation section 12 in real time without being counted by the detection section 10. The calculation unit 12 calculates the difference between the mandrel penetration depth and the drain material casting length, immediately calculates the amount of co-up, and further compares this amount of co-up with a preset allowable amount of co-up. Ru.
Incidentally, this co-rising phenomenon also occurs in the pen recorder of the recording section 17, as shown by the line segment Q in FIG. 6, where there is no rising.

Here, if the calculated co-increase amount exceeds the allowable value, a warning will be issued with a blinking display and a buzzer.

The operator who learns of the co-upward abnormality due to the alarm immediately redoes the mandrel 7 while it is in the middle of its penetration.

When the drain material D is properly placed, the lower end of the mandrel 7 is raised to a predetermined height above the ground surface, as shown in FIG. 5F, and the removal is completed.

The drain material D is cut at a predetermined above-ground exposure length f as shown in FIG.
is pulled out again for attachment of the anchor plate 9 and moved on to preparation for the next casting operation.

Although the above embodiment describes simultaneous casting using two mandrels, the present invention is not limited to this, and simultaneous casting using two or more mandrels is also possible.

Further, in the above embodiment, the drain material installation work on the ground has been described, but the drain material installation work may also be performed on water such as the sea or a river. In this case, it is necessary to consider water depth, tide level, etc. as calculation factors.

Further, in the above embodiment, the drain material is drawn out from the reel when the mandrel is pulled out, but it may be pulled out when the mandrel is pushed in.

[Effects of the invention] (1) The mandrel penetration depth and drain material casting length, which change every moment during mandrel driving and pulling, are continuously detected, and these detected data are compared with a preset allowable co-rise. By appropriately calculating the setting data of the amount and design pouring depth, it is possible to grasp in real time abnormalities in the drain material's co-upward movement and abnormalities in the state of mandrel penetration, and it is possible to stop the mandrel in the middle of driving and re-place it. This not only improves work efficiency but also reduces wastage of drain material.

(2) Since the mandrel penetration depth, drain material placement length, set placement depth, etc. are displayed, the mandrel penetration status and drain material placement status can be constantly monitored and abnormalities can be immediately confirmed.

(3) Necessary data such as mandrel penetration depth, drain material casting length, design casting depth, common uplift amount, etc. can be recorded and saved.
