Abstract
The invention relates to a construction method of a building project, in particular to a construction method for first soil filling and then casting at a settlement post-cast strip of a top plate of a basement. The construction method comprises the following steps of chiseling and cleaning the two sides of the settlement post-cast strip; supporting a formwork and a support system at the lower part of the settlement post-cast strip; manufacturing an inverted U-shaped reinforced concrete cover plate at the upper part of the settlement post-cast strip; pre-embedding a steel pipe on the cover plate; adhering soft plastic bars at the corners of the cover plate; constructing a waterproof layer of the top plate of the basement; constructing a waterproof protecting layer of the top plate of the basement; backfilling soil; arranging a protecting device; casting concrete onto the settlement post-cast strip. The construction method has the advantages that the soil can be backfilled at the upper part without sealing the post-cast strip, and then a flat site land is formed, so as to facilitate the plane arrangement of the site; a grouting enlarging space which is higher than the top plate of the basement is formed under the inverted U-shaped cover plate, so the casting thickness of the post-cast strip is guaranteed; after soil backfilling is realized for a post-cast hole passage of the steel pipe, the concrete is cast onto the post-cast strip; by arranging the soft plastic bars, the nonuniform settlement amounts at the two sides of the settlement post-cast strip can be adjusted and absorbed, and the tension fracture of a coil on the cover plate is prevented.
Description
Technical field
The present invention relates to building engineering construction method, specifically a kind of basement roof pouring after settlement place first banket after casting construction method.
Background technology
Modern overlooking community is designed with high residential building and the overlooking commercial building of multilayer and underground garage more, and the building basement of differing heights links together because of the using function of underground garage.Because highrise building and multistory building are comparatively large to the different loading of ground effect, thus cause the differential settlement of ground, basement structure is occurred even to rupture in crack.In order to avoid this problem, usually the multistory building design of basement pouring after settlement around highrise building, pouring after settlement whole load after highrise building agent structure binds has added and has been poured into a mould after settlement stability, from pouring after settlement indwelling to pouring after settlement casting complete, forming complete basement space often needs for a long time.Basement is imperfect, cannot carry out the backfill construction of basement roof top, thus construction plant cannot make full use of, greatly affect engineering construction efficiency, restriction construction period.
Summary of the invention
The present invention is intended to solve the problems referred to above that prior art exists, and provides a kind of with low cost, easy and simple to handle, can basement roof pouring after settlement place that significantly accelerating construction progress improves construction quality first banket after casting construction method.
The technical scheme that the present invention solves the employing of described problem is:
First banketing after-pouring construction method in a kind of basement roof pouring after settlement place, carries out in the steps below:
(1) cutter cleaning is picked in pouring after settlement both sides;
(2) pouring after settlement bottom installs template and support system;
(3) muscle is tied up on pouring after settlement top, formwork builds inverted U cast-in-situ concrete cover plate, embedded steel tube in cover plate;
(4) soft plastic rod is pasted in cover plate bight;
(5) basement roof construction of waterproof layer;
(6) basement roof fish tail and waterproof layer construction;
(7) backfill construction;
(8) embedded steel tube protective device is set;
(9) pouring after settlement concrete is built by embedded steel tube.
Adopt the present invention of technique scheme, compared with prior art, its beneficial effect:
1. can realize not closing ater-casting and carrying out top backfill construction, form smooth on-the-spot place, be beneficial to spot plane and arrange;
2. arrange inverted U cover plate, form the grouting exceeding basement roof under cover plate and add large space, what ensure ater-casting plate builds thickness;
3. arrange steel pipe back pouring hole road realize backfill complete after ater-casting concrete after-pouring.
4. 50 soft plastic rods are set and can regulate absorption pouring after settlement left and right sides differential settlement amount, prevent the coiled material drawing crack of cover plate top.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
In figure: scaffold support standpipe 1-1, the stupefied 1-2 of steel pipe master, flitch 1-3, composite board 1-4; Pouring after settlement 2; Basement roof 3; Concrete cover 4; Waterproofing course 5; Steel pipe 6; Temporary plugging plank 7; Reinforced frame protective emblem 8; Soft plastic rod 9; Fish tail and waterproof layer 10; Backfill 11.
Detailed description of the invention
The present invention is further elaborated for the embodiment provided below in conjunction with accompanying drawing, but embodiment does not form any restriction to the present invention.
See Fig. 1, the basement roof pouring after settlement place described in the present embodiment first banket after casting construction method, carry out in the steps below:
(1) pouring after settlement 2 both sides are picked cutter and are cleaned out.
(2) pouring after settlement 2 bottom installs template and support system; Template and support system are made up of scaffold support standpipe 1-1, the stupefied 1-2 of steel pipe master, flitch 1-3, composite board 1-4, and scaffold support standpipe 1-1, the stupefied 1-2 of steel pipe master are f48*3.0 steel pipe, scaffold support standpipe 1-1 in length and breadth to 300 one, step pitch 1800; The stupefied 1-2300(400 of steel pipe master) together; Flitch 1-3 is 50 × 100 flitch 150 one; Composite board 1-4 is 18 thick composite board.
(3) muscle is tied up on pouring after settlement 2 top, formwork builds inverted U cast-in-situ concrete cover plate 4, pre-buried f200 steel pipe 6 in concrete cover 4, exterior angle, the concrete cover 4 top fillet of falling f50.
(4) f50 soft plastic rod 9 is pasted in concrete cover 4 bight, presets pouring after settlement 2 left and right sides differential settlement amount, prevents the coiled material drawing crack of concrete cover 4 top.
(5) waterproofing course 5 of construction basement roof 3, waterproof edge concrete cover 4 top is rolled up to steel pipe 6 suitable for reading always, and concrete cover 4 top is that empty paving is to adapt to the amount of tension that pouring after settlement 2 left and right sides differential settlement causes.
(6) build the fish tail and waterproof layer 10 of basement roof 3, the cotton felt-cloth of the waterproof on steel pipe 6 wraps up as topping.
(7) backfill 11 is constructed, and the interim capping of steel pipe 6 temporary plugging plank 7 suitable for reading, backfill 11 surface roadways hardens, and corresponding steel pipe 6 place suitable for reading arranges reinforced frame protective emblem 8, avoids wheel to roll.
(8) agent structure bind 14 days after pouring after settlement 2 possess when building condition, excavate local, steel pipe 6 top backfill, expose steel pipe 6 mouthfuls, build ater-casting concrete by steel pipe 6 mouthfuls, build height high to 500mm in steel pipe 6, by minor diameter vibrating spear vibration compacting.
(9) in steel pipe 6, remaining space fills out the compacting of element soil timber, mouth of pipe shutoff 3mm steel plate.
The foregoing is only the better feasible embodiment of the present invention, not thereby limit to interest field of the present invention, the equivalent structure change that all utilizations manual of the present invention and accompanying drawing content are done, be all contained within interest field of the present invention.
