Description
Technical field
The present invention relates to a kind of leakage proof wall, especially a kind of cut-pff wall in deep covering layer.
Background technique
Cut-pff wall is the main vertical seepage control technology in current shot shape stratum, and it is anti-that it serves not only as permanent ground
Seep, to just leak and there are the dike of dangerous situation, dam carry out leak-stopping processing, also act as at the antiseepage to Temporary Cofferdam, foundation pit etc.
Reason, barricade, anti-scour wall etc. as building are occurred sedimentation by dam body gravity pressure, library water lateral pressure, soil at both sides and generated
Additional lateral pressure and head difference bring horizontal thrust etc. so that wall is pressurized, cuts, curved effect, wall is caused to be opened
It splits, ultimately causes leakage proof wall leak.
Therefore, such as make cut-pff wall in use, prevent wall leakage, be a urgent problem.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of cut-pff wall in deep covering layer, leakage proof walls
Crack is preset, copper sheet sealing is set at crack in advance, so that leakage proof wall cracking position is clear, well in advance antiseepage is arranged
It applies, the later period effectively can avoid cut-pff wall from leaking.
To solve the above-mentioned problems, the technical scheme adopted by the invention is that: a kind of antiseepage in deep covering layer
Core-wall is arranged inside the local material dam body built on deep covering layer in wall, and cut-pff wall is embedded in lower part basement rock, core-wall upstream and downstream
Side setting filter material and transition zone, core-wall lower part are connected with cut-pff wall, which is characterized in that framework of steel reinforcement is set in cut-pff wall,
Parting is set on cut-pff wall, the parting on cut-pff wall is flexibly connected by copper seal, and copper seal is fixed on framework of steel reinforcement, only
Hard PVC stick is set inside the round copper lug of water copper sheet, wraps up pitch spunyarn outside hard PVC stick.
For cut-pff wall with a thickness of 80~120cm, parting height spacing is 6~8m.
Copper seal 3~5mm of thickness, 40~50cm of width, copper seal installation position is antiseepage wall thickness 1/3 and 2/3
Place.
The hard PVC stick diameter being arranged inside round copper lug among copper seal is 50~80mm, outsourcing pitch spunyarn
With a thickness of 10~15mm.Copper lug internal diameter is equal with the cylinder diameter that PVC stick and its outsourcing pitch spunyarn form.
Beneficial effects of the present invention: parting is set on cut-pff wall in advance when construction, copper sheet sealing is set on parting, will be prevented
Handling flexibly at wall parting is seeped, wall when external force at parting by being preferentially subjected to displacement, the good ductility of copper sheet sealing
Can to avoid by drawing crack, play the role of preventing leakage.The present invention uses the handling flexibly of cut-pff wall parting, excellent using Copper water stop
Ductility, can effectively avoid cut-pff wall caused by the water pressure of library crack leak the phenomenon that.
Detailed description of the invention
Fig. 1 is of the invention for the cut-pff wall schematic diagram in deep covering layer.
Fig. 2 is that copper sheet sealing, hard PVC stick and the pitch spunyarn for the cut-pff wall in deep covering layer of the invention shows
It is intended to.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, 2, the cut-pff wall in deep covering layer of the invention, the locality built on deep covering layer 10
Core-wall 3 is set inside material dam body 1, and cut-pff wall 4 is embedded in lower part basement rock 9, and filter material 2 and transition zone is arranged in 3 upstream and downstream side of core-wall
12,3 lower part of core-wall is connected with cut-pff wall 4, and framework of steel reinforcement 13 is arranged in cut-pff wall 4, sets parting 5, cut-pff wall 4 on cut-pff wall 4
On parting 5 be flexibly connected by copper seal 6, copper seal 6 is fixed on framework of steel reinforcement 13, the round copper of copper seal 6
Hard PVC stick 7 is set inside nose 11, wraps up pitch spunyarn 8 outside hard PVC stick 7.
For cut-pff wall 4 with a thickness of 80~120cm, 5 height spacing of parting is 6~8m.
6 3~5mm of thickness of copper seal, 40~50cm of width, 6 installation position of copper seal is 4 thickness of cut-pff wall, 1/3 He
At 2/3.
7 diameter of hard PVC stick being arranged inside round copper lug 11 among copper seal 6 is 50~80mm, outsourcing pitch
Spunyarn 8 is with a thickness of 10~15mm.The cylinder diameter phase that 11 internal diameter of copper lug is formed with PVC stick 7 and its outsourcing pitch spunyarn 8
Deng.
Hard PVC stick 7 and pitch spunyarn 8 play a supporting role to the round copper lug of copper seal, anti-to guarantee to pour
Copper seal circle copper lug is not by concrete compressive strain when seeping wall.
