Abstract
The invention relates to an island constructing caisson without leveling of a foundation bed. The island constructing caisson without leveling of the foundation bed comprises a prefabricated caisson body, a grouting bag is arranged on a bottom plate of the caisson, and the grouting bag is connected with a grouting pipe. The invention further relates to a construction method of the island constructing caissons. The method includes the following steps that one caisson is positioned according to pre-determined design; the caisson is made to sink through ballast; when the caisson sinks to the pre-determined height, the caisson body is supported with a supporting device; binding material is injected to the grouting bag from the grouting pipe; after the binding material solidifies and reaches certain strength, the supporting device is taken out; sand and the ballast are injected to the bottom of the caisson, and pouring is performed; after the caisson is installed, a next caisson is installed according to the same steps. Due to the fact that grout is injected into the grouting bag after the caisson is placed well, concrete sets fast, the caisson body can be supported by the set concrete, setting is easy to control in the early stage of a caisson foundation, and setting and inclination in the construction period are not be caused easily.
Description
Technical field
The present invention relates to a kind of caisset, and the construction method of this caisson.
Background technology
Generally build adopt of cofferdam, island flattens after processing bedding more, carry out again the installation of member, this member belongs to conventional dam structural shape, is widely used, but seldom adopts under the condition of environment Cha Zhu island in the dam constructions such as sand preventing dyke, mole, regulating structure, shore protection.Existingly without base bed flattening technique Zhu island member or caisson, be mainly gravity structure, dependence is built island member or caisson deadweight and backfill weight and is resisted wave, wind-force, water pressure and soil pressure effect, maintain structural entity stable, bear wave ability strong, dykes and dams are from great, and base pressure is large, not high to ground requirement for bearing capacity, conventionally need riprap foundation, and need to first flatten processing to bedding.Execution conditions more complicated in some cases, the construction conditions such as deep water, soft base, high wind, torrent, wave, macroseism are more complicated, and the design and installation of this structure are all considered above-mentioned bad working environments, can overcome above-mentioned problem.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of vertical and level of caisson that can effectively improve to the caisson of supporting capacity, control caisson sedimentation and horizontal movement, and the construction method of this caisson.
With regard to regard to the caisson of base bed flattening Zhu island, for solving the problems of the technologies described above, of the present inventionly without base bed flattening Zhu island caisson, comprise prefabricated caisson, described Bottom plate of sinkbox place arranges slip casting pouch, and slip casting pouch connects Grouting Pipe.
Described caisson comprises base plate, and base plate place reserves groove, and described slip casting pouch is arranged in groove, and note sand hole is set on base plate, and Grouting Pipe connects slip casting pouch by note sand hole.
The bottom margin of described caisson one end arranges protuberance, and the corresponding position of the other end arranges the recess matching.
The top of described caisson one end is provided with nose girder, and the top of the other end is provided with the guide groove matching with described nose girder.
With regard to the construction method without base bed flattening Zhu island caisson, this construction method without base bed flattening Zhu island caisson comprises the following steps, A, by caisson by predetermined design location; B, by ballast, make caisson sinking; When C, caisson sinking arrive predetermined altitude, with bracing or strutting arrangement, prop up casing; D, from Grouting Pipe, to slip casting pouch, inject cementitious material; E, when cementitious material, solidify after reaching some strength and withdraw from bracing or strutting arrangement; G, to caisson bottom note sand, ballast, builds; H, complete after the installation of first caisson, by same step, next caisson is installed.
When loading makes caisson sinking, caisson is aimed to the protuberance of previous already installed caisson with one end of recess, the recess of a rear caisson is placed on the protuberance of previous caisson, the other end of a rear caisson supports with bracing or strutting arrangement.
When the first casing is installed,, when next caisson is installed, one end that nose girder is set is aimed to the guide groove of previous caisson by one end that guide groove is set outwardly, ballast, makes caisson sinking, and nose girder enters guide groove.
The cementitious material of injecting to slip casting bag from Grouting Pipe is concrete.
Adopt after such structure, due to after placing caisson to slip casting in slip casting pouch, concrete rapid solidification, can, so that the concrete support casing after solidifying is easily controlled the sedimentation of laying foundation initial stage, be difficult for causing s Settlement in Construction Period and inclination.The bottom margin of caisson one end arranges protuberance, and the corresponding position of the other end arranges the recess matching, and during installation, the recess of a rear caisson can be placed on the protuberance of previous caisson, plays the effect of support.The top of caisson one end is provided with nose girder, and the top of the other end is provided with the guide groove matching with described nose girder, and during installation, the nose girder of a rear caisson enters in the guide groove of previous caisson, plays good positioning action.Caisson good stability of the present invention, easy construction, builds island fast, and speed of application is fast, and consumptive material is economized, and the duration is short, little to surrounding environment influence, and the dismounting workload in cofferdam is little, and construction costs is low.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the left view of caisset of the present invention.
Fig. 2 is the front view of caisset of the present invention
