Abstract

The present invention relates to municipal construction field, specifically a kind of external water drainage waterproof method of pipe gallery;It is characterized in that being included in both sides other than piping lane sump position corridor body excavates water filter well foundation pit;Filter pipe outsourcing gauze and geotextiles are hung to filter well foundation pit section by section;Chimney filter is installed to top, away from below ground about 0.6m, is stayed for drainpipe and is set channel;Water pump and drainpipe laying;After filter well and foundation pit backfill, self-opening type immersible pump is connect with scupper hose, is slowly hung to infiltration bottom, hose top is stretched out from the hole of cutting outside filter well.After seepage well is constructed, just proximad leads to municipal drainage well direction and excavate drainpipe groove, the gradient 2% lays Φ 150PVC drainpipes later, and comb finishes backfill groove in time and tamps.Construction method of the present invention is simple, and principle is reliable and construction is quick, can effectively prevent Groundwater infiltration piping lane;Thus great application value.

Description

The external water drainage waterproof method of pipe gallery
Technical field
The present invention relates to municipal construction field, specifically a kind of external water drainage waterproof method of pipe gallery.
Background technology
With the construction and development of China's urban infrastructure, pipe gallery has all been built in more and more cities, this is pair Urban underground space reasonable development and the important measure utilized.However the leakage problems of pipe gallery and the underground space, it is always Annoying the problem of this industry development.Currently, for its structural shape and waterproof material, waterproof mainly takes structure certainly anti- The measure that water and outer waterproof are applied simultaneously, although taking the method for two kinds of waterproof measures while application, still degree not Same also will appear some leakages.Therefore, at present there is an urgent need to find a kind of waterproof method implemented in a manner of water drainage, with Make up the deficiency of above-mentioned waterproof method.
Invention content
The purpose of the present invention is to provide a kind of easy to implement and at low cost quick, great application value it is comprehensive Close the external water drainage waterproof method of piping lane.
A kind of external water drainage waterproof method of pipe gallery, including
Step 1, setting filter well;
Φ 800, the water filter well foundation pit of depth about 800mm, hole are excavated in step 1.1, the both sides other than piping lane sump position corridor body It is thick not less than the concrete 200mm of C20 that strength grade is completely poured at bottom;
Step 1.2, by filter pipe outsourcing gauze and geotextiles, hung section by section later to filter well foundation pit, it is thick in being filled outside chimney filter Sand, chimney filter fill medium coarse sand and coordinate alternately with foundation pit backfill;
Step 1.3, chimney filter are installed to top, away from below ground about 0.6m, are led to municipal drainage well direction and are dug 150 holes about Φ Hole is stayed for drainpipe and sets channel;
Step 2, water pump and drainpipe laying;
After step 2.1, filter well and foundation pit backfill, self-opening type immersible pump is connect with scupper hose, is slowly hung to oozing Well bottom, hose top are stretched out from the hole of cutting outside filter well;Wherein, the suitable buried-pipe laying of self-opening type water pump transmission line of electricity, Buried depth, protected mode have to comply with transmission line of electricity and lay related administrative provisions.
Step 2.2, seepage well construction after, just proximad lead to municipal drainage well direction excavate drainpipe groove, the gradient 2%, Φ 150PVC drainpipes are laid later, and comb finishes backfill groove in time and tamps.
The external water drainage waterproof method of the pipe gallery, filter pipe are concrete without sand filtration water pipe or hard polyvinyl chloride Other filter pipes of material type.
The characteristic that the present invention is stored using groundwater seepage and gap, by between the external waterproof roll of piping lane and protective layer Gap, as the channel of underground ponding seepage flow, then pass through drainage and forced drainage, reduce the external level of ground water in corridor, with this Prevent Groundwater infiltration piping lane.
Description of the drawings
Fig. 1 is the constructing structure schematic diagram of this draining waterproof method.
Specific implementation mode
It is further illustrated the present invention below by way of specific embodiment.
As shown in Figure 1, a kind of external water drainage waterproof method of pipe gallery, including
Step 1, setting filter well;
Step 1.1, the both sides other than piping lane sump position corridor body, excavation Φ 800, the water filter well foundation pit 1 of depth about 800mm, It is thick not less than the concrete 200mm of C20 that strength grade is completely poured at hole bottom;
Step 1.2, by filter pipe outsourcing gauze and geotextiles, hung section by section later to filter well foundation pit, it is thick in being filled outside chimney filter Sand, chimney filter fill medium coarse sand and coordinate alternately with foundation pit backfill;
Step 1.3, chimney filter are installed to top, away from below ground about 0.6m, are led to municipal drainage well direction and are dug 150 holes about Φ Hole is stayed for drainpipe and sets channel;
Step 2, water pump and drainpipe laying;
After step 2.1, filter well and foundation pit backfill, self-opening type immersible pump 2 is connect with scupper hose, is slowly hung to oozing Well bottom, hose top are stretched out from the hole of cutting outside filter well;Wherein, the suitable buried-pipe laying of self-opening type water pump transmission line of electricity, Buried depth, protected mode have to comply with transmission line of electricity and lay related administrative provisions.
Step 2.2, seepage well construction after, just proximad lead to municipal drainage well direction excavate drainpipe groove, the gradient 2%, Φ 150PVC drainpipes are laid later, and comb finishes backfill groove in time and tamps.
The external water drainage waterproof method of the pipe gallery, filter pipe are concrete without sand filtration water pipe or hard polyvinyl chloride Other filter pipes of material type.
The basic ideas taken of the present invention are:The generally use of the outer fish tail and waterproof layer of piping lane is laid bricks or paving polystyrene type Cystosepiment, has certain gap between protective layer and coiled material, the bright water in the external underground in corridor is mainly stored in this.Protective layer has been constructed Filter well is arranged against the fish tail and waterproof layer concrete water filter pipe of Φ 500 in piping lane both sides external sump position in Bi Hou, Concrete water filter pipe outsourcing gauze and geotextiles, well head 0.2m preferably above ground level, and it is capped well lid.Shaft bottom is arranged self-opening type and dives under water Pump and scupper hose, scupper hose buried-pipe laying outside away from the ground positions about 0.6m stretching water filter well access municipal drainage system nearby System.Immersible pump voluntarily starts after water level reach a certain height in well, and well internal water accumulation is excluded by drainpipe.If things go on like this carry out, The outer level of ground water of piping lane can decline rapidly, until being down to piping lane bottom plate or less.
