Abstract

The invention relates to a building engineering construction method, in particular to a high-rise building basement roof settlement post-pouring joint advanced water stop construction method. The construction method includes the steps that the two sides of a post-pouring joint are chiseled and cleaned; a formwork and a supporting system are erected on the lower portion of the post-pouring joint; waterproof coiled materials are laid at positions, on the two sides of the post-pouring joint, of a basement roof; walls are built on the waterproof coiled materials respectively; the upper portions of the walls are covered with reinforced concrete cover plates; an underground body structure waterproof layer is constructed; backfill construction is carried out; post-pouring joint concrete is poured. The construction method has the advantages that a basement roof waterproof layer, a protective layer and outdoor backfill can be integrally constructed and are prevented from being interfered by basement roof post-pouring joint construction, and the construction quality of an underground waterproof structure is guaranteed. Impurities, rainwater and water for construction are effectively prevented from flowing into a basement through the post-pouring joint.

Description

Basement in high rise building top board pouring after settlement advance water stop construction method
Technical field
The present invention relates to building engineering construction method, specifically a kind of basement in high rise building top board pouring after settlement advance water stop construction method.
Background technology
because function needs main tower and annex to be linked to be entirety in large public building and high-rise building design, for reducing between high-rise main tower and low layer podium because of structural internal force that differential settlement causes, or the thermal stresses that large area concreting causes, separate with ater-casting between main tower and annex, make its each self-forming independent monomer, can in construction period sedimentation separately, the adverse effect that differential settlement also can be avoided to produce, can meet again the requirement of building function.Because pouring after settlement concreting must after agent structure completes, settlement stability can carry out, basement roof waterproof can not sequential production, pit backfill can not normally carry out, construction plant does not have work plane, and the leakproof of basement can not be guaranteed, and will bring various unfavorable factor to subsequent construction, have a strong impact on construction normally to carry out, restriction duration progress.
CN201120519897.0 discloses a kind of poured band of outer wall of basement advanced water-stopping structure, is applicable to the construction of the vertical ater-casting of basement in high rise building, and is not suitable for the construction of basement roof ater-casting.
CN201210246324.4 discloses a kind of construction method of basement roof pouring after settlement safeguard measure, and its effect only for the protection of ater-casting, but not relates to the problem of waterproof, backfill in the subsequent construction of ater-casting.
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 significantly accelerating construction progress, improves the basement in high rise building top board pouring after settlement advance water stop construction method of construction quality.
The technical scheme that the present invention solves the employing of described problem is:
A kind of basement in high rise building top board pouring after settlement advance water stop construction method, carries out in the steps below:
(1) cutter is picked in pouring after settlement both sides to clean out;
(2) pouring after settlement bottom installs template and late poured band support system;
(3) waterproof is done in pouring after settlement both sides;
(4) water after settling and bring both sides to build waterproof by laying bricks or stones to lead wall, lead wall top formwork tie up muscle pouring reinforcement concrete cover plate in waterproof, waterproof leads wall and cover plate, and to smear 1:2.5 cement mortar 20 thick, and R angle is smeared at negative and positive angle place;
(5) construction basement waterproof roofing layer, waterproof edge cover plate top is connected with both sides, ater-casting waterproof, ensures that waterproofing for basement is continuous whole;
(6) basement roof fish tail and waterproof layer is built;
(7) backfill construction;
(8) agent structure bind 14 days after pouring after settlement possess when building condition and build this place's concrete by vertical ater-casting, top, vibration compacting magma receives face;
(9) enter from vertical ater-casting, Construction Later Casting Zone place waterproof is linked to be entirety with the waterproof of constructing in advance.
Adopt the present invention of technique scheme, compared with prior art, its beneficial effect is:
1. can realize not closing ater-casting and advanced water-stopping is constructed, form smooth on-the-spot place, be beneficial to spot plane and arrange;
2. build wall and cast-in-place cover plate by laying bricks or stones, ensure that basement waterproofing is continuous whole;
3. under cover plate, ater-casting is built by vertical ater-casting, can ensure ater-casting concrete pouring quality;
4. the waterproof and basement roof waterproof of leading ater-casting place under wall cover plate are linked to be entirety, make ater-casting discharge water one protective barrier many, complete design concept, avoids ater-casting waterproof to leak because various factors causes, and realizes the advanced waterproof construction in ater-casting.
As preferably, the present invention further technical scheme is:
Described late poured band support system adopts f48*3.0 steel pipe scaffold, and vertical rod is spacing 800mm in length and breadth.
Described waterproof is led wall and is adopted 240 masonries, height 1200mm.
Double-deck f14 reinforcing bar@200 mm is joined in described reinforced concrete cover plate.
Described fish tail and waterproof layer is the thick C20 pea gravel concreten of 100 mm that 80 thick poly-plastic insulation boards are built.
