Abstract
The invention discloses a method for carrying out settlement of an underground wall structure by means of high-pressure water guns. The method for carrying out the settlement of the underground wall structure by means of the high-pressure water guns comprises the following steps that (a) a field is leveled, and setting-out is conducted for positioning; (b) the underground wall structure is poured in place; (c) a total station is installed; (d) pre-preparation for the settlement of the underground wall structure is conducted; (e) the high-pressure water guns are arranged; (f) settlement of the first stage of the underground wall structure is conducted by means of the high-pressure water guns; (g) the second stage of the underground wall structure is poured in place; and (h) the underground wall structure is reinforced through grouting. According to the method for carrying out the settlement of the underground wall structure by means of the high-pressure water guns, an annular slurry groove is formed in the periphery of the underground wall structure, so that a soil body supporting the underground wall structure collapses in order, and accordingly the underground wall structure sinks slowly under the action of the self-weight, and construction of an underground building wall and a building enclosure is achieved; the method for carrying out the settlement of the underground wall structure by means of the high-pressure water guns has the advantages of being high in construction speed and high in working efficiency.
Description
Technical field
The present invention relates to the construction of civil engineering foundation engineering technical field underground structure body of wall and space enclosing structure, the method for underground wall body structure sediment implemented by especially a kind of giant.
Background technology
In the foundation construction of building site, before excavation of foundation pit, first to implement the construction of underground structure space enclosing structure, then in foundation ditch, implement precipitation and excavation, after having excavated, the construction of underground wall body structure can be implemented, because this working procedure is complicated, cost is high, efficiency is low and do not favored, underground wall body structural entity sedimentation construction method is adopted to be exactly form of construction work space enclosing structure and underground wall body structure united two into one, the construction of prior art underground wall body structure, that underground wall body structure that is prefabricated or cast in situs is located on ground, the soil of underground wall body inside configuration support zone is excavated, namely to cut the earth sedimentation, design elevation is sunk down into after making underground wall body structure rely on the gravity of structure self to overcome the frictional resistance of periphery, then bed course and construction of bottom plates is carried out, this technique is gone along with sb. to guard him before instead of excavation of foundation pit and the construction of wall body structure, there is saving of labor, timesaving advantage is rather well received, and Problems existing is, the harmony of shoveling sedimentation to the amount and shoveling of excavating the underground wall body support structure position soil body requires very high, otherwise will cause the inclination of underground wall body structure, tear, once run-off the straight correction is very difficult, shoveling sedimentation also easily causes structural outer surface settlement, cuts the earth in the foundation ditch that especially groundwater table is high, and the impact caused periphery soil body environment is comparatively large, thus also causes the local buckling of underground wall body structure, in addition this construction method is also by the restriction of space enclosing structure foundation depth, is not suitable for the space enclosing structure construction that basis is darker.
Summary of the invention
The method of underground wall body structure sediment implemented by a kind of giant that the object of the invention is to provide for the deficiencies in the prior art, the present invention adopts giant to form mud annular groove at the periphery of underground wall body structure, cause the soil body of support underground wall body structure to be burst in order to collapse, underground wall body structure is slowly sunk under the effect of deadweight, to realize the construction of underground wall body and space enclosing structure, there is the advantage that speed of application is fast, operating efficiency is high.
The concrete technical scheme realizing the object of the invention is:
A method for underground wall body structure sediment implemented by giant, and its feature comprises the steps:

C), total powerstation is installed
At the position periphery for implementing underground wall body sedimentation, total powerstation is installed;
D), prepare before underground wall body structure sediment
For multistage underground wall body structure, implement the operation of sedimentation step by step, first will complete the form removable of the first order underground wall body structure of maintenance, take out the protection cushion block under the underground wall body structure basil;
E), layout giant
Choose giant number cover, be distributed in the periphery of underground wall body inner structural wall, described giant is made up of shower nozzle, high-pressure water pipe and guide peg, and shower nozzle is located at the termination of high-pressure water pipe, and guide peg is strapped in high-pressure water pipe, and giant layout is complete;
F) sedimentation of first order underground wall body structure, is implemented with giant
Open high-pressure hydraulic pump, the shower nozzle ejection water under high pressure of giant, the soil body under the high pressure water impact underground wall body structure basil, the soil body of underground wall body structural base is made to form mud annular groove, cause the soil body of support underground wall body structure to be burst in order to collapse, underground wall body structure is slowly sunk under the effect of deadweight; Now, the dynamic vertical degree that total powerstation monitoring underground wall body structure is sunk, and the flow controlling giant is implemented to control, adjust to the sinking watching of underground wall body structure, until first order underground wall body structure sediment arrives the absolute altitude of design, close high-pressure hydraulic pump and make the shower nozzle of giant stop water spray;
G), cast-in-place second level underground wall body structure
The basis of first order underground wall body structure installs template, cloth muscle, cast-in-place second level underground wall body structure, until after second level underground wall body structure completes maintenance, reopens high-pressure hydraulic pump and again implement; And complete all the other grade of underground wall body structure successively, until afterbody underground wall body structure has been sunk;
H), grouting and reinforcing underground wall body structure
After descending wall body structure to be deposited to design elevation fully, grout and strengthen processing is carried out at the periphery of underground wall body structure inside and outside wall, grouting and reinforcing completes until arrive defects liability period, can implement the precipitation in underground wall body structure 1, soil excavation, bed course and construction of bottom plates.
The present invention adopts giant to form mud annular groove at the periphery of underground wall body structure, cause the soil body of support underground wall body structure to be burst in order to collapse, underground wall body structure is slowly sunk under the effect of deadweight, to realize the construction of underground structure underground wall body and space enclosing structure, there is the advantage that speed of application is fast, operating efficiency is high.
