Abstract
The invention provides a later-construction method for an inner wall of a basement. The later-construction method comprises the steps that during structure storey construction, inner wall inverse-inserting ribs are inserted into hidden beams of the later-made inner wall; the later-made inner wall and the hidden beams of floors are provided with water stopping strips which swell with water; bottom templates of the hidden beams are provided with inner wall inverse-inserting rib holes, and the inverse-inserting ribs are inserted into the inner wall inverse-inserting rib holes; water stopping steel boards are arranged in inner wall construction gaps in the floor where the later-made inner wall is located and the floor above the later-made inner wall; concrete conveying holes are formed from a floor plate of the floor above the later-made inner wall to a floor plate of the floor where the later-made inner wall is located; stuffy demolition supports are disassembled, the inner wall inverse-inserting ribs are connected, and lack supply is conducted on the inner wall. By means of the method, construction quality of the inner wall is effectively improved, and a construction period is shortened.
Description
Technical field
The present invention relates to Building Engineering Design field, relate in particular to a kind of method of constructing after basement inwall.
Background technology
At present, along with deep-foundation pit engineering more and more occurs, go along with sb. to guard him the way of diaphragm wall and the two wall unifications of structure outer wall of basement and also used widely.Above-mentioned structure outer wall of basement is known as again inwall, generally take along the mode done from bottom to top isostructure floor construct successively; But go along with sb. to guard him the more special engineering of operating mode for some, local support cannot need to retain certain hour rear dismountable along tearing open, cause the construction that cannot make progress smoothly of the inwall of support zone.Fig. 1 is the foundation pit structure schematic top plan view near the base pit engineering of subway.With reference to Fig. 1, this project foundation ditch is divided I-1, I-2, II-1, II-2 and five pittings of II-3 altogether, and constructs successively according to the order of I-1 → I-2 → II-2 → II-1/II-3, and the order of supporting removal is just in time contrary; I-1, I-2 Ge She tri-road concrete supports, due to I-2 basement floor large area disappearance, therefore I-2 second concrete support is torn open after need retaining, and corresponding I-1 second concrete support is torn open after also needing to retain, and causes the inwall of I-1 second concrete support respective side suitable to do.
If take the method for first pre-buried inwall reinforcing bar when Construction of Supporting to reach the once object of construction, also will cause a series of problem, the one, when support and excavation and construction, embedded bar easily damages; The 2nd, support with the waterproof of inwall interface and be prone to problem; In addition, different from the concrete grade of inwall owing to supporting, embedded bar is once constructed and cannot be guaranteed the construction quality of inwall.
Summary of the invention
The invention provides a kind of method of constructing after basement inwall, to solve, support vexed tearing open in situation, the problem that the inwall of support zone cannot make progress smoothly and construct.
The invention provides a kind of method of constructing after basement inwall, comprising: structure floor when construction, after insert inwall in doing the dark beam of inwall and fall joint bar; After do inwall and the dark Liang Chu of floor arranges water-swellable sealing rod; Dark beam bottom mother plate is outputed the inwall hole of falling joint bar, inwall is fallen to joint bar and insert the described inwall hole of falling joint bar; After do inwall floor and above steel plate for sealing water is set in the inwall constuction joint of floor; After do floor above inwall until stay and establish concrete haul hole in doing the floor of inwall floor after described; Remove the vexed support of tearing open, connect described inwall and fall joint bar, the described inwall of filling a vacancy.
Preferably, after described, do inwall and the dark Liang Chu of described floor also arranges the pre-buried Grouting Pipe that repeats.
Preferably, on described dark beam bottom mother plate, pad is established extruded sheet.
Preferably, the quantity of described extruded sheet is two, and the thickness of described two extruded sheets is different, forms stairstepping.
Preferably, the thickness of a described extruded sheet is 100cm, and the thickness of extruded sheet is 30cm described in another piece.
Preferably, fall before joint bar described inwall to be fallen to joint bar and described steel plate for sealing water to clear up connecting described inwall.
Preferably, described inwall falls the employing straight thread connector suitable for reading of joint bar, and described inwall falls the end opening of joint bar and adopts colligation to connect.
Compare with the method that supports interior pre-buried inwall bar one-time construction, the present invention has following beneficial effect:
1. method provided by the invention can effectively improve the construction quality of inwall, and the reduction of erection time;
2. compared to cutting the earth and driving phase, it is that embedded bar is not easy to be damaged that the inwall in structure construction stage falls joint bar;
3. the waterproof effect of inwall upper and lower constuction joint can be guaranteed by embedded water stop steel plate, expansion sealing strip, and has lacked the constuction joint supporting together with inwall, has lacked an infiltration hidden danger;
4. can guarantee that inwall concrete adopts same label, guarantee architecture quality.
