Detailed description of the invention
Below in conjunction with specific embodiment, construction joint of tunnel percolating water punishment system described in the utility model is described further, but protection domain of the present utility model is not limited to this.
Embodiment 1
Certain highway tunnel is built to be open to traffic more than ten years, has occurred at present the diseases such as lining cutting is ftractureed, peeled off, percolating water, and wherein Portal Section Construction seam place percolating water phenomenon is more serious.Find by Field Research, this constuction joint percolating water is earth surface water source supplying type, and water percolating capacity is little, constuction joint is wet stain shape outward, but long-term tax of percolating water is stored in constuction joint, and tunnel lining is produced to oxide etch effect, causes constuction joint place concrete cracking, peels off.Therefore should adopt construction joint of tunnel percolating water punishment system described in the utility model processing, described system comprises groove 41, raggle 42, capillary penetrating drainage band 5, loss circulation material layer 6, waterproof cement mortar layer 7, waterproof coating layer 8, transverse wave pipe 11, and described groove 41 is grooves of widening towards country rock 1 direction centered by constuction joint 4 on tunnel lining surface; The groove that described raggle 42 is deeply cut a hole towards country rock 1 direction for 41 times at groove centered by constuction joint 4; Described capillary penetrating drainage band 5 is two-layer altogether, be located in raggle 42, each layer respectively with upstream face towards the two side of raggle 42, its lower end is connected with transverse wave pipe 11; Described loss circulation material layer 6, waterproof cement mortar layer 7 and surface with waterproof coating layer 8 by inner from outward successively full-filling on groove 41; The dark 10cm of described groove 41, wide 5cm; Described raggle 42 is deep to canvas cloth 2, width is 8mm; Described capillary penetrating drainage band 5 comprises pore 9 and groove 10; Reserved hole between described capillary penetrating drainage band 5 bilayers.
When enforcement, carry out in accordance with the following steps: 1) construction joint of tunnel place raggle: from 10cm position, constuction joint percolating water EXIT POINT top to tunnel bottom section, cut old waterproofing materials and the loose concrete of its internal failure, in raggle process, should guarantee that groove width is 8mm, and try not to destroy original canvas cloth, finally brush scum silica frost with wire brush, and water is rinsed well; 2) lay capillary penetrating drainage band: in raggle, lay two-layer capillary penetrating drainage band, using capillary penetrating drainage with a side of groove as upstream face and towards the raggle wall of this side; 3) capillary penetrating drainage band is connected with transverse wave pipe: the end of the transverse wave pipe in former drainage system cuts out the groove of wide 10mm, long 60cm, by the groove of capillary penetrating drainage band lower end access transverse wave pipe; 4) constuction joint outside punishment: in tunnel lining centered by constuction joint, dig out the groove of dark 10cm, wide 5cm, with loss circulation material and waterproof cement mortar, groove shutoff is filled and led up, loss circulation material and waterproof cement mortar bed thickness are all 5cm, and groove surfaces is punished with water-repellent paint.
In the utility model, capillary penetrating drainage band is little outside greatly in pore design, groove water inlet width 0.3mm, and than pore diameter, 1mm is narrow, has very strong anti-blockage capability; And central drainage is carried out in transverse wave pipe, central row ditch that the utility model can make full use of in original drainage system.Therefore, better for the constuction joint percolating water situation punishment effect of oozing slowly state, can drain in time constuction joint internal water accumulation, avoid further developing of lining cutting cracking, water leakage defect, its construction sequence is simple, workable, the feature of environmental protection is strong, economic benefit and social benefit higher.
