Abstract
The invention discloses a waterproof construction method for anti-floating anchor rods. The waterproof construction method for anti-floating anchor rods includes the following construction steps that A, a concrete cushion is poured; B, cement paste is poured around the anti-floating anchor rods; C, cement-based crystallization waterproof paint is brushed; D, a waterproof roll layer is laid; E, waterproof grease is poured, and a waterproof protection layer is poured. The waterproof construction method for anti-floating anchor rods has the advantages that gaps between the anchor rods and bed rock can be effectively sealed for avoiding water burst; the problem that because waterproof paint on the root portions of rebars of the anchor rods is not compact, water is prone to leakage is solved; a water stop steel plate can stop capillary water from rising along rod bodies to cause water seepage hazards, the water stop effect is good, and leakage resistance is improved.
Description
Technical field
The present invention relates to a kind of building operations waterproof method, in particular, relate to a kind of anti-float anchor rod waterproof construction method.
Background technology
Current in construction work underground structure, anti-float anchor rod is directly communicated with basement rock and base plate, runs through substrate waterproofing course, and therefore the possibility increase of infiltration is very large.In present atlas waterproofing process, without the processing of anti-float anchor rod node waterproof, anti-float anchor rod waterproofing node is processed and is generally selected buildings waterproof structure pile foundation waterproofing process; But Pile Diameter is greater than anti-float anchor rod diameter conventionally, be much smaller with respect to pile foundation levels operation face, when brushing cement based penetration crystallization type water proofing paint, waterproof effect is difficult to ensure; Pile foundation end face exceeds the 50mm of waterproofing course basic unit conventionally, and when anti-floating anchor rod grouting and essential bearing stratum one flat, anti-float anchor rod end face, lower than waterproofing course basic unit, cannot make waterproofing course closure.If anti-float anchor rod is in basement rock issue place in addition, use merely sealing cement sealing cannot block issue, the capillary water path of rising along the body of rod is longer, leaves over infiltration hidden danger.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, and a kind of good water-proof effect is provided, improve efficiency of construction, reduce the anti-float anchor rod waterproof construction method of construction cost.
Anti-float anchor rod waterproof construction method of the present invention, comprises following construction sequence:
A, by clean anti-float anchor rod removing surface, vertically put into underground soil layer, then fluid concrete bed course on underground soil layer;
B, around anti-float anchor rod, joints cement is starched only, cement paste build the highly height sum for underground soil layer and concrete cushion; Cement paste adopts delamination pour slurry, repeatedly mends slurry, and slip casting is not rocked anti-float anchor rod in complete 24 hours;
C, cement paste and concrete cushion upper surface are put within the scope of radius 250-350mm and cleaned out centered by anti-float anchor rod, brushing cement based crystalline waterproof coating material three to five times, emphasis brushing position is anti-float anchor rod and concrete cushion intersection;
After D, cement based crystalline waterproof coating material solidify, at cement based crystalline waterproof coating material surface uniform brushing special treating agent, pending dose of dry tack-free rear laying water-proof coiled material layer forms Φ 80-120 cylinder around anti-float anchor rod;
After E, waterproof roll layer install, in cylinder, pour into waterproofing unction, fill compacting, build fish tail and waterproof layer, bottom board after fish tail and waterproof layer solidifies in Φ 80-120 cylinder periphery.
Described waterproof roll layer is BAC adhesive waterproof coil, and thickness is 3mm.
When described step D middle berth is set up defences water coiled material layer, if in environment temperature time construction lower than 10 °, because waterproof roll layer adhesion strength is little, when construction, adopt benzine blow lamp that cement based crystalline waterproof coating material and waterproof roll layer are heated a little and baked to micro-molten state, to strengthen the adhesion strength between waterproofing materials and waterproof matrix, then the laying water-proof coiled material layer of constructing.
On described anti-float anchor rod, top is fixedly welded with steel plate for sealing water.
Described waterproofing protection layer material is C20 concrete, and thickness is 50-70mm.
The height that described anti-float anchor rod forms Φ 80-120 cylinder is around 50-70mm.
The invention has the beneficial effects as follows: gap water burst between (1) effective shutoff anchor pole and basement rock; (2) solve the easily phenomenon of infiltration of anchor pole reinforcing bar root water-repellent paint imprecision; (3) steel plate for sealing water is set and can stops that capillary water rises and causes infiltration hidden danger along the body of rod, stagnant water effect is good, improves leakage resistance.
