Description
Technical field
The present invention relates to the realm of building construction, more particularly to antiseep between a kind of underground exterior-protected structure and main body side wall
Construction method.
Background technique
Main body side wall：On foundation structure, receives, undertakes and transmit all upper loads and maintain the stabilization of structure
Property.
Impermeable structure：The waterproofness of concrete itself.
Slip casting：By in curable slurries injection rock, soil, the crack of concrete or hole, pass through displacement, filling, extruding
Etc. modes to improve the method for its physico-mechanical properties.
Existing tunnel water-proof system is essentially divided into two parts, and one is impermeable structure, and impermeable structure is waterproof
The first line of defence plays an important role, but in reality, by project water price and geology, construction technology, method, level,
The influence of the factors such as concrete material quality, pouring quality, maintenance quality is very easy to generate structural percolating water.Secondly
For mode material waterproofing, it is laid with steel or flexible waterproof material, between tunnel main structure and enclosed structure to reach waterproof
Effect.
If percolating water occurs for constructing tunnel, processing method is substantially to use outer brill injected hole in the place of discovery percolating water
Leak stopping, or the material plastering leak stopping for using polyurethane, epoxy resin, dry cement to mix colloid etc.The shortcomings that prior art
It is discovery percolating water reprocessing, no precautionary measures and expensive.
Summary of the invention
The purpose of the present invention is to provide a kind of at low cost, artificial less investment, material is simple and can handle cavity simultaneously
The construction method of antiseep between the underground exterior-protected structure and main body side wall of problem.
The technical solution adopted by the present invention is that：
The construction method of antiseep, includes the following steps between a kind of underground exterior-protected structure and main body side wall：
A, then construction underground exterior-protected structure clears up the medial surface of underground exterior-protected structure；
B, several Grouting Pipes are made, slurry outlet is set in the surrounding of each Grouting Pipe, each Grouting Pipe is then embedded to underground
The upper end of the inside of building enclosure, each Grouting Pipe protrudes from underground exterior-protected structure；
C, in the inside of underground exterior-protected structure construction main body side wall；
D, the upper end of each Grouting Pipe is connected to slip casting machine, completes slip casting work.
As an improvement of the above scheme, when making Grouting Pipe, the spacing of adjacent two slurry outlet is controlled in 25~30cm.
As an improvement of the above scheme, when built-in slip casting pipe, the spacing of adjacent two Grouting Pipe is controlled in 4~6m.
As an improvement of the above scheme, step c is before main body side wall of constructing, Grouting Pipe far from underground exterior-protected structure one
Side is laid with waterproof layer.
As an improvement of the above scheme, the area that waterproof layer is laid with is equal to the medial surface area of underground exterior-protected structure.
As an improvement of the above scheme, waterproof layer is using rigid waterproof material.
As an improvement of the above scheme, waterproof layer uses waterproof material flexible.
Beneficial effects of the present invention：The construction method of antiseep passes through in underground between this underground exterior-protected structure and main body side wall
Pre-buried several Grouting Pipes between building enclosure and main body side wall, and slip casting work is completed, pre- anti-seep water in advance, pole may be implemented
The earth reduces the expense of processing percolating water；After the medial surface deformation of underground exterior-protected structure generates cavity, this step of slip casting can also
To complete the work of dense packing effect, the stability of structure is improved.
Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings：
Fig. 1 is the schematic diagram of overall structure work progress.
Specific embodiment
Referring to Fig. 1 of side view, a kind of construction method of present invention antiseep between underground exterior-protected structure and main body side wall, packet
Include following steps：
A, then construction underground exterior-protected structure 1 clears up the medial surface of underground exterior-protected structure 1, convenient for later step slip casting
Slurries are bonded medial surface；
B, several Grouting Pipes 31 are made, slurry outlet are set in the surrounding of each Grouting Pipe 31, each Grouting Pipe 31 uses PVC material
Material, the spacing of adjacent two slurry outlet is between 25~30cm, and the diameter of each slurry outlet is 15~20cm, then each Grouting Pipe 31
It is embedded to the inside of underground exterior-protected structure 1, the spacing between adjacent two Grouting Pipe 31 is between 4~6m, for subsequent connection slip casting
The upper end of machine, each Grouting Pipe 31 protrudes from underground exterior-protected structure 1, only sees a Grouting Pipe 31 from seeing for Fig. 1；
C, in the inside of underground exterior-protected structure 1 construction main body side wall 2；
D, the upper end of each Grouting Pipe 31 is connected to slip casting machine, completes slip casting work, and what when slip casting used can be cement
Slurry or dual slurry.
Slurry outlet is easily reduced grouting pressure too much, and correspondingly the spacing of adjacent two Grouting Pipe 31 will shorten, and leads to cost
Rise；Slurry outlet is to reduce slip casting efficiency instead very little.The parameter designing of above-mentioned injected hole 32 and Grouting Pipe 31 can be in construction
Various aspects factor controlling in more balanced level.
The construction method of antiseep passes through in underground exterior-protected structure 1 and main body side between this underground exterior-protected structure and main body side wall
Pre-buried several Grouting Pipes 31 between wall 2, and slip casting work is completed, pre- anti-seep water in advance may be implemented, greatly reduce processing
The expense of percolating water.Concrete structure is easy to shrink so that side is uneven, i.e., in the inside of underground exterior-protected structure 1 in molding
After face deformation generates cavity 5, this step of slip casting can also complete the work of dense packing effect, improve the stability of structure.
As preferred embodiment, step c is before main body side wall 2 of constructing, in Grouting Pipe 31 far from underground exterior-protected structure 1
Side be laid with waterproof layer 4, waterproof layer 4 be laid with area be equal to underground exterior-protected structure 1 medial surface area.Waterproof layer 4 can be with
Using waterproof material rigidity or flexible.The waterproof material such as cement, sandstone and additive and mixture of rigidity, it is flexible
Waterproof material such as pitch, flexible web etc..Dual waterproofing design can further avoid unexpected leakage.
Certainly, the design creation is not limited to above embodiment, and the combination of the various embodiments described above different characteristic can also
To reach good effect.Those skilled in the art can also make equivalent change on the premise of without prejudice to spirit of the invention
Shape or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
