Description
Technical field
The utility model belongs to double-arched tunnel guarded drainage technical field, is specifically related to a kind of double-arched tunnel mid-board waterproof and water drainage system drainable waterproofing plate.
Background technology
Double-arched tunnel structure is a kind of Tunnel structure occurred along with high-grade highway construction development in the last thirty years, has good applicability and superiority, is particularly useful for that land used is limited, alpine terrain is complicated, road represents the situations such as difficulty.Meanwhile, double-arched tunnel structure compensate for the deficiency of separate tunnel just, applies increasingly extensive.
Guarded drainage is the Focal point and difficult point problem needing in double-arched tunnel design, construction to solve.Mid-board is the weak link place of double-arched tunnel guarded drainage, mid-board guarded drainage be exactly by left and right main hole vault converge water effectively arrange guide to mid-board side feet gutter in.But, if quality is slightly not in place in the construction of double-arched tunnel mid-board guarded drainage, very easily cause occurring double-arched tunnel mid-board top leaky edema evil.
There is water leakage defect in double-arched tunnel mid-board, its reason has following several respects: one, Geological Reasons, and the country rock of mid-board top and main arch ring junction is repeatedly subject to blast disturbance, and lithology is more broken, causes this position to become the concentration zones of ponding and percolating water; , between both sides, mid-board top and left and right main hole secondary lining, there is vertical equity constuction joint and circular construction joint in two, reasons in structure; Three, construction reason, double-arched tunnel construction of central division wall operation is many, and mid-board top splash guard is difficult to protection, and reinforcing bar reserved on mid-board is being difficult to avoid with burning during main hole secondary lining reinforcement welding and poke splash guard.
At present, double-arched tunnel mid-board guarded drainage mainly contains three kinds of forms: hole, left and right, mid-board top waterproofing course communication type guarded drainage, hole, left and right, mid-board top waterproofing course disconnection type guarded drainage, composite middle partition wall guarded drainage; Hole, left and right, mid-board top waterproofing course communication type: namely refer to be arranged by waterproofing course in mid-board top, forms an overall waterproofing course; Hole, left and right, Zhong Qiang top waterproofing course disconnection type: namely with mid-board center line for standard, waterproofing course is divided into the independent waterproof construction that two are symmetrical, the guarded drainage work that two row's vertical drainage pipes carry out mid-board is set; Composite middle partition wall guarded drainage: namely refer to the alternate manner being different from above-mentioned two kinds of mid-board guarded drainage modes.
The key of double-arched tunnel mid-board guarded drainage is the guarded drainage at its top.Current general way is, first does blind pipe and carries out country rock draining, then does splash guard and carry out waterproof.But there is many problems in above-mentioned guarded drainage mode: 1. the laying of multiple waterproof/drainage structure is quite complicated at the construction field (site); 2. practice test, the structure through guarded drainage process still there will be percolating water phenomenon; 3. construction period length consuming time, construction costs is large; 4. at present engineering still guarded drainage layer is divided into anti-, arrange two-layer performing, the linking of structure often easily goes wrong.
