Abstract

A thin-wall prefabricated overlapped concrete underground diaphragm wall is formed by splicing of a plurality of prefabricated wall panels, wherein each of the prefabricated wall blocks is equipped with a plurality of rectangular holes to decrease weight for easier lifting and rib plates are disposed among the rectangular holes; prefabricated notches are disposed on two ends of the wall and expansion sealing rods are embedded at the notches; and after earth cutting and groove formation, the wall panels are lifted in place for the splicing, concrete is poured inside a cavity and the cavity and the prefabricated wall form a whole together. The thin-wall prefabricated overlapped concrete underground diaphragm wall is characterized in high strength and good anti-leak performance.

Description

The prefabricated superimposed concrete underground continuous wall of a kind of thin-walled
Technical field
Building operations
Background technology
Basement engineering two wall unifications, combine space enclosing structure and outer wall of basement structure, save soil, expand basement area, save construction costs, have wide prospect, have practical value.Existing diaphragm wall adopts cast-in-place mode to construct conventionally: box cut section, put down reinforcing cage, concreting.There are some shortcomings in this cast-in-place mode: due to stratum reason, surface is very crude, even has large hole wall collapse hole etc., need cut in a large number the trouble with liner body of wall, also has the mass defect that reinforcing bar is exposed.Prefabricated basement continuous wall plate, any surface finish, has avoided the shortcoming of common diaphragm wall, has improved workmanship.But, if wallboard is prefabricated (real core) entirely, general diaphragm wall structure stress is huge, thickness of slab must be very large (thin having a 500mm, the thick 1000mm that surpasses), causes plate weight too large, lifting difficulty, and joint antiseep is difficult to process, and the wallboard of thin-walled hollow is not enough to bear huge subsurface pressure, and iterative structure can overcome both shortcomings well.
Utility model content
The purpose of this utility model, is to provide a kind of new concrete diaphragm wall, by polylith splicing prefabricated wallboard, is formed.Each dry wall piece, by concrete slab, floor and rectangular enclosure, formed, in concrete slab, be furnished with vertical transverse reinforcement, in floor, have tension rib to connect two panels, there is light weight, lifting easily, the loop wheel machine of the same tonnage larger wallboard of can slinging, quickening progress, reduces piece, there is the anti-slurry bar of reserved expansion waterproof end, waterproof and concrete spillage.After soil diging groove-forming, the splicing of wallboard hoisted in position, placing of concrete in cavity, acting in conjunction forms an integral body together with precast concrete panel.The feature with intensity height and better anti-leakage property.
Accompanying drawing explanation
Accompanying drawing 1 is the prefabricated superimposed concrete underground continuous wall elevation of a kind of thin-walled.
Accompanying drawing 2 is the prefabricated superimposed concrete underground continuous wall horizontal sectional drawings of a kind of thin-walled.
The specific embodiment
First prefabricated thin-wall concrete underground continuous wall plate.Secondly, adopt common continuous wall trench underground method soil diging groove-forming, after excavation first paragraph groove section, the crane wallboard of slinging, puts into groove in place, adjusts spacing and error, excavation second segment groove section, put into second wallboard, with first inlay in place after, will reserve the anti-slurry bar of expansion waterproof and expand, concrete perfusion in cavity, after concrete setting, two bodies of wall are formed to the common stressed integral body of an antiseep, same method block-by-block all the other wallboards of constructing, until all complete.
More than show and describe basic principle of the present utility model, principal character and advantage are described; under the prerequisite that does not depart from spirit and scope of the present utility model, the utility model also has various changes and modifications, and these changes and improvements all fall into protection domain of the present utility model.

Claims (1)

1. the prefabricated superimposed concrete underground continuous wall of thin-walled, by two sides cage of reinforcement and lacing wire and stirrup, form cage shape, reinforcing cage is put into underground tank, primary concreting concrete, it is characterized in that: installation form inside and outside cage of reinforcement and lacing wire and hoop reinforcement cage, build in advance thin wall concrete, in the middle of every block of wallboard, there are several rectangle holes, between rectangle hole, there is floor, there is prefabricated notch wall end, pre-buried expansion sealing grouting bar, after prefabricated underground continuous wall plate is in place, secondary concreting in prefabricated notch and rectangle hole.
