A construction method for a basement construction bottom plate includes the following steps that (1) a shear wall and a shear column are normally poured and punned to below the construction bottom plate by 550 mm; (2) inside and outside backfill soil is filled to be below the poured shear wall and the poured shear column by 400 mm and is punned; (3) concrete is poured and punned to construct a bracket, a groove is reserved and an insertion bar is connected normally according to design sizes; (4) an outer wall of the shear wall, the superstructure of the shear column and a coiled material waterproof part of the outer wall are constructed, a coiled material waterproof part is added to a second construction joint, and after a waterproof protection layer of the outer wall is completed, backfill soil is backfilled to the outer wall; (5) after the backfill soil becomes dense and solid within three months under normal circumstances, an under layer of the bottom plate, the coiled material waterproof parts and a protection layer are constructed; (6) bottom plate reinforced concrete is normally constructed; (7) the concrete is maintained, a joint of the construction bottom plate is examined, and if separation occurs, the joint is repaired in a factice caulking mode. The construction technology is simple, the construction period and quality are guaranteed, reworking is avoided, the manufacturing cost is lowered, energy is saved, and the environment is protected.
Description
Technical field
The present invention relates to the construction method of a kind of basement structure base plate, for building field.
Background technology
Base plate and the wall construction of basement are that the problem received publicity is compared in building operations always, " underground waterproof engineering inspection of quality specification " (GB50208-2011) are at 5.1.3 article, and " building operations handbook " (second edition), at 13-1-3-10 constuction joint, at 19-5-9-1, article 6. (2), all explicitly call for: body of wall horizontal construction joint should stay to be located at and exceed backplate surface and should be not less than on the body of wall of 300mm.Vertical construction joints should avoid underground water and the more location of crevice water, and should combine with deformation joint.For above-mentioned requirements, concrete actual conditions are difficult to reach sometimes, such as: Liuzhou City's engineering, and building area more than 110,000 square metre, containing the high building totally 5 of 28 floor to 18 floor, big basement 1 layer more than 1.5 ten thousand square metre, 5 high buildings are raft foundation, and annex is distributing single column foundation, high building and annex buried depth are from-10.5 meters to-5 meters not etc., raft plate and single column foundation banket, then is up structure base plate, be connected with each shear wall and post.During construction, banket by specification palpus compaction by layers and the compacting of every thickness 30cm to 50cm palpus, but the compacting of large-area fill-back earth big machinery is difficult to accomplish, existing bankets the most deeply to reach more than 5 meters is difficult to closely knit problem in a short time, if constuction joint stays by specification and establishes during construction, cavity can be formed under basement bottom board, after spending year half a year to 1, there will be the quality problems of differential settlement and the phenomenon such as bottom slab crack and infiltration.At this moment, usually construction is watered by after structure base plate, constuction joint is established and reserved steel bar or rear bar planting at wall column and plate link position, and only in the concrete of connection construction seam position, stay groove or raggle water expandable waterstop to process to waterproof, this way all forms a vertical line constuction joint at wall column and plate interface, all there is waterproof hidden danger, the general equal humidity of constuction joint interface and infiltration.What is called " the ten seams nine leak " phenomenon of Here it is engineering circles, visible, the waterproof slab of basement is construction work significant problem anxious to be resolved.
Summary of the invention
The object of the invention is to provide the construction method of a kind of basement structure base plate, flowing water can be made to infiltrate circuit and bend long enough, make waterproof coiled material avoid Points And lines interface, take face interface, thus ensure waterproof quality, thoroughly overcome the problems referred to above that existing technique exists.Be applicable to because compactness of banketing is difficult to meet code requirement in short-term, in the construction of the structure base plate that basement bottom board does not stress.
Technical scheme of the present invention is: provide a kind of basement to construct the construction method of base plate, comprise the steps:
1, normally water smash shear wall, post to structure base plate under 550mm,
2, inside and outside backfill is filled to and waters 400mm under shear wall, post and tamp,
3, by design size normally water smash construction concrete bracket and reserved groove be connected joint bar,
4, to construct shear wall exterior wall, post superstrate portion complete exterior wall waterproof coiled material, increase one waterproof coiled material at the 2nd constuction joint place, road, backfill exterior wall after completing external wall waterproof topping and banket,
5, under normal circumstances 3 months backfill closely knit after, constructing structure bottom cushion and waterproof coiled material and topping,
6, normal construction structure baseplate reinforcing bar concrete,
7, curing concrete also checks structure backplane interface, if there is separation to take ointment filleting mode to repair.
Outstanding advantages of the present invention is:
1. construction technology is simple.This method with common water smash shear wall, post is identical with base plate, operational method is simple, and operative is convenient.
2. the duration can be ensured.Water after structure base plate, compactness of avoiding banketing is difficult to meet code requirement in short-term and stop work.
3. can ensure the quality of products, provide against hidden trouble, avoid doing over again, thus cost is reduced.This method makes flowing water infiltrate circuit and bends long enough, and make waterproof coiled material avoid Points And lines interface, waterproof coiled material takes face interface, thus in technique, make waterproof quality be guaranteed.
4. energy-conserving and environment-protective.Material requested with common water smash shear wall, post is identical with base plate, can repeat turnover use, embody the feature of energy-conserving and environment-protective.
