Abstract
What the present invention relates to a kind of base plate waterproofing leads wall in the narrow especially Water separating flow-guiding Seepage method even without work plane and under being in infiltration situation of work plane.The steps include: having the hand excavation gutter outside wall of leading of seepage water to locate to work plane spaciousness, and dig sump herein; 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; French drain forms brick wall together with brick code, and brick wall height is to leading wall height; 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; Construct this position bed course, lead wall; The construction waterproofing course of base plate, topping and base plate.The present invention can make to lead wall and bed course is in dry state, ensures the normal construction of waterproofing course; Waterproofing course in foundation ditch can continuous laying, forms entirety with the waterproofing course at other positions of foundation ditch; Easy construction, expense is low, good seepage-proof property.
Description
Technical field
The present invention relates to construction techniques, especially a kind of base plate waterproofing lead wall in the narrow especially Water separating flow-guiding Seepage method even without work plane and under being in infiltration situation of work plane.
Background technology
Building deep foundation ditch bottom surface under normal circumstances general lead to stay outside wall at base plate establish the work plane of wider (about 2m) to set up to land double-pole scaffold, and in foundation ditch bottom surface, gutter (300mm is wide) and sump are set from the position that sidewall is about outside 500mm.And for bustling location, city, around construction plant is narrow and small when, the outer face width of base plate reserved when deep foundation pit precipitation and design of its support little (the narrowest place 800mm).After deep foundation pit supporting construction, foundation pit side-wall middle and lower part portion there will be more seepage water, adopts conventional method not good to rises treatment effect.Because base plate leads 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 to lead on wall, a part flows down along foundation pit side-wall, cause the bed course at this position and lead wall and be in seepage water situation always, 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 provide a kind of and can ensure bed course, the base plate of leading wall and base plate waterproofing execution conditions leads 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 leads the Water separating flow-guiding Seepage method under wall place infiltration situation, carries out in the steps below:
A. there iing the hand excavation gutter outside wall of leading of seepage water to locate to work plane spaciousness, and digging sump herein;
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 brick wall together 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. to construct the waterproofing course of base plate, topping and base plate.
Technique scheme of the present invention, have employed the material that not only can be used as backfilling but by its infiltration and the common brick of constructability and cobble french drain combine formation flow-guiding channel, and adopt the brick wall risen at code completely to hang Polypropylence Sheet outward to form water barrier and be guided to being dropped in the water of leading on wall in french drain, the seepage water finally making to lead wall place to be flow in sump by french drain and is drained by water with water pump, thus ensure that bed course, leads 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, make this position lead wall and bed course is in dry state, ensure 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, good seepage-proof property, avoids waterproofing course to play bulging quality problems.

Fig. 1 is embodiment of the present invention constructing structure schematic diagram.
In figure: 1-foundation pit walls, 2-brick wall, 3-french drain, Polypropylence Sheet in 4-ditch, 5-bed course, 6-waterproofing course, 7-topping, 8-base plate, 9-leads wall, 10-antiseepage, water conservancy diversion Polypropylence Sheet.
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.
See Fig. 1, the base plate described in the present embodiment leads the Water separating flow-guiding Seepage method under wall place infiltration situation, carries out in the steps below:
A. there iing the hand excavation outside wall 9 that leads of seepage water to be about the wide gutter of 200mm to work plane spaciousness place, and digging sump herein.
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, form brick wall 2(together with brick code to lead between wall 9 and foundation pit walls 1), brick wall 2 height is to leading wall 9 height.
D. brick wall 2 facade risen at code completely hangs 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 surface.
E. construct this position bed course 5, lead wall 9.
F. to construct the waterproofing course 6 of base plate 8, topping 7 and base plate 8.
