Abstract
The invention relates to a waterproof flow diversion seepage-proofing construction method under the condition that a guide wall of a base plate waterproof layer has a very narrow working face and even is free of the working face and subjected to water seepage. The waterproof flow diversion seepage-proofing construction method has the steps of artificially excavating a drainage ditch from the outer side of the guide wall where seepage water exists to the wide position of the working face and excavating a water collection pit at the position; laying plastic cloth in the drainage ditch, using graits to fill up and level up the drainage ditch to form a flow diversion blind ditch and arranging a water pump in the water collection pit to drain water; building bricks on the blind ditch to form a brick wall, wherein the brick wall is higher than the guide wall; hanging plastic cloth on a brick wall facade for preventing seepage and flow diversion, wherein the upper end of the plastic cloth is higher than the guide wall, and the lower end of the plastic cloth extends to the surface of the blind ditch; constructing a cushion layer and the guiding wall at the position; constructing a waterproof layer and a protective layer of a base plate and the base plate. The waterproof flow diversion seepage-proofing construction method can enable the guide wall and the cushion layer to be in a dry state, ensures normal construction of the waterproof layer. The waterproof layer in a foundation pit can be continuously laid and forms a whole with the waterproof layer at other positions of the foundation pit. Construction is simple and convenient, the cost is low, and the seepage preventing effect is good.
Description
Technical field
The present invention relates to construction techniques, especially a kind of base plate waterproofing to lead wall narrow especially even without work plane and the Water separating flow-guiding Seepage method under infiltration situation at work plane.
Background technology
Building deep foundation ditch bottom surface is generally led wall at base plate under normal circumstances and is stayed the work plane of establishing wider (about 2m) to set up to land double-pole scaffold outward, and the position outside the about 500mm of sidewall arranges gutter (300mm is wide) and sump in foundation ditch bottom surface.And for bustling location, city, around in the narrow and small situation in construction plant, the reserved outer face width of base plate little (the narrowest 800mm of place) when deep foundation pit precipitation and design of its support.After deep foundation pit supporting construction, part position, foundation pit side-wall middle and lower part there will be more seepage water, adopts conventional method not good to rises treatment effect.Because base plate is led wall, work plane is narrow especially even without work plane outward, a water part of oozing out be dropped in along anchor cable and waist rail lead on wall, a part flows down along foundation pit side-wall, cause the bed course at this position and lead wall always in seepage water situation, waterproofing course cannot be constructed, and follow-up work cannot be carried out.
Summary of the invention
There is the construction problem in seepage water situation in the waist rail that the present invention is intended to solve above-mentioned deep foundation pit supporting structure sidewall and protrusion, and the base plate that provides a kind of and can ensure bed course, leads wall and base plate waterproofing execution conditions is led brick wall french drain water barrier water conservancy diversion Seepage method under wall place infiltration situation.
The technical scheme that the present invention solves the problems of the technologies described above employing is:
Base plate is led the Water separating flow-guiding Seepage method under wall place infiltration situation, carries out in the steps below:
A. lead outside wall hand excavation gutter to the spacious place of work plane what have seepage water, and dig herein sump;
B. in gutter, lay Polypropylence Sheet, and fill and lead up with cobble, form the french drain of water conservancy diversion, water pump is set in sump water is drained;
C. on french drain, form together brick wall with brick code, brick wall height is to leading wall height;
D. completely hang Polypropylence Sheet antiseepage, water conservancy diversion at brick wall facade, Polypropylence Sheet upper end exceeds leads wall, lower end to french drain surface;
E. construct this position bed course, lead wall;
F. construct waterproofing course, topping and the base plate of base plate.
Technique scheme of the present invention, adopt the material that can be used as backfill again can be by the common brick of its infiltration and constructability and the cobble french drain formation flow-guiding channel that combines, and adopt the brick wall that rises at code completely to hang Polypropylence Sheet outward to form water barrier and be guided in french drain being dropped in the water of leading on wall, the seepage water that finally makes to lead wall place flow in sump by french drain and water is drained with water pump, thereby has ensured bed course, lead the execution conditions of wall and base plate waterproofing.Therefore, the present invention compared with prior art, has following advantage:
1. antiseepage, water conservancy diversion measure are set, and what make this position leads wall and bed course in dry state, ensures waterproofing course normal construction;
2. the waterproofing course in foundation ditch can continuous laying, forms entirety with the waterproofing course at other positions of foundation ditch;
3. easy construction, expense is low, and good seepage-proof property avoids waterproofing course to play bulging quality problems.

Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, and object is only better to understand content of the present invention.Therefore, the cited case not limits the scope of the invention.
Referring to Fig. 1, the base plate described in the present embodiment is led the Water separating flow-guiding Seepage method under wall place infiltration situation, carries out in the steps below:
A. locate to work plane is spacious in the wide gutter of the about 200mm of wall 9 outside hand excavation of leading that has seepage water, and dig herein sump.
B. in gutter, lay Polypropylence Sheet 4 in ditch, and fill and lead up with cobble, form the french drain 3 of water conservancy diversion, water pump is set in sump water is drained.
C. on french drain 3, forming together brick wall 2(with brick code leads between wall 9 and foundation pit walls 1), brick wall 2 height are to leading wall 9 height.
D. brick wall 2 facades that rise at code are completely hung antiseepage, water conservancy diversion Polypropylence Sheet 10, and the upper end of antiseepage, water conservancy diversion Polypropylence Sheet 10 will exceed leads wall 9(and generally exceed 500～700mm), lower end is to french drain 3 surfaces.
E. construct this position bed course 5, lead wall 9.
F. construct waterproofing course 6, topping 7 and the base plate 8 of base plate 8.
