Abstract
A thin wall prefabricated superposed concrete underground continuous wall is made of splicing multiple prefabricated wall plates. Each prefabricated wall block is provided with multiple rectangular holes in the middle to reduce weight and be easy to hoist, and rib plates are arranged among the rectangular holes. Two ends of the wall are provided with prefabricated notches, and expansion water stopping strips are embedded in the notches. After soil is digged to form a groove, the wall plates are hoisted in place for splicing, and concrete is poured in cavities to jointly form a whole together with a prefabricated concrete wall. The thin wall prefabricated superposed concrete underground continuous wall has the advantages of high intensity and good penetration resistance.
Description
Technical field
Building operations
Background technology
The unification of basement engineering two walls combines space enclosing structure and outer wall of basement structure, saves the soil, enlarges the basement area, saves construction costs, and wide prospect is arranged, and has practical value.Existing diaphragm wall adopts cast-in-place mode to construct usually: the box cut section, put down reinforcing cage, concreting.There are some shortcomings in this cast-in-place mode: owing to the stratum reason, the surface is very crude, even large hole wall collapse hole etc. is arranged, and need cut in a large number the trouble with the liner body of wall, also has the exposed mass defect of reinforcing bar.Prefabricated basement continuous wall plate, any surface finish has been 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 500mm being arranged, the thick 1000mm that surpasses), causes plate weight too large, the lifting difficulty, and the 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.
Summary of the invention
Purpose of the present invention provides a kind of new concrete diaphragm wall, is formed by the polylith splicing prefabricated wallboard.Each dry wall piece, formed by concrete slab, floor and rectangular enclosure, be furnished with in the concrete slab in length and breadth to reinforcing bar, in floor, have tension rib to connect two panels, have light weight, lifting easily, the loop wheel machine of the same tonnage larger wallboard of can slinging, the quickening progress reduces piece, there are the anti-slurry of the expansion of reservation waterproof bar, waterproof and concrete spillage in the end.Behind the soil diging groove-forming, the splicing of wallboard hoisted in position, placing of concrete in cavity forms an integral body with the precast concrete panel acting in conjunction.Characteristics with intensity height and better anti-leakage property.
Description of drawings
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
Prefabricated thin-wall concrete underground continuous wall plate at first.Secondly, adopt common continuous wall trench underground method soil diging groove-forming, after the excavation first paragraph groove section, the crane wallboard of slinging, it is in place to put into groove, adjusts spacing and error, excavation second segment groove section, put into second wallboard, with first inlay in place after, will reserve the anti-slurry of expansion waterproof bar and expand, concrete perfusion in the cavity, after the concrete setting two bodies of wall are formed the common stressed integral body of an antiseep, same method block-by-block all the other wallboards of constructing are until all finish.
More than show and describe basic principle of the present invention, principal character and advantage are described, the present invention also has various changes and modifications under the premise without departing from the spirit and scope of the present invention, and these changes and improvements all fall into protection scope of the present invention.
Claims (2)
1. the prefabricated superimposed concrete underground continuous wall of thin-walled has several rectangle holes to alleviate hoisting weight in the middle of every block of wallboard, between the rectangle hole floor is arranged, and there is prefabricated notch the wall end, pre-buried expansion sealing grouting bar.
2. after prefabricated underground continuous wall plate was in place, concreting in prefabricated notch and rectangle hole after solidifying coupled together wallboard, together the shared load.
