Description
Technical field
The utility model relates to tunnel water handling technical field, especially a kind of point of pool waterproof layer structure.
Background technology
In Mountain Tunnels construction, surface drainage is more flourishing, and The turbulent river crashes its way through, and engineering geology is complicated.Tunnel surrounding mostly is weak wind slap, and Rock Joints Surrounding, crack are extremely grown.Whole section water burst at the bottom of tunnel arch wall tunnel, crack swelling amount is large, there is certain pressure, full section is as rained in torrents, flow is larger, and water yield does not subtract for a long time, add difficulty of construction, be mainly manifested in: crevice water reduces country rock angle of internal friction, affect face self stability, cause jewel hole powder charge difficulty, jetting cement adheres to bad easy formation cavity and efficiency is low, drainage system discharge capacity can not meet excretion requirement, tunneling boring water burst is difficult to concentrated drainage, splash guard lays difficulty, and ordinary concrete cannot overcome inner a large amount of capillary tube and gap and occur crack and infiltration, therefore, for the problems referred to above, we propose a kind of point pool waterproof layer structure.
Utility model content
Prior art can not meet the needs of people, for making up prior art deficiency, the utility model aims to provide one and takes radial grouting, slip casting radius is large, slip casting effect is better, utilizes slurries to close water delivery crack and water burst space in basement rock, reduces country rock transmission coefficient, overcome the inner a large amount of capillary tube of ordinary concrete and the gap crack occurred and the phenomenon that seeps water, practical point pool waterproof layer structure.
For achieving the above object, the utility model by the following technical solutions: a kind of point of pool waterproof layer structure, at least comprises water knockout drum, band drain, annular row water pipe, slip casting country rock body, return pipe, feed pipe and waterstop; Described water knockout drum is arranged on band drain upper end, and water knockout drum is close-coupled at band drain upper surface; Described band drain is arranged on the right side of feed pipe, and feed pipe and band drain junction are provided with waterstop; Described annular row water pipe is arranged on immediately below band drain, and is welded by steelframe between annular row water pipe with annular row water pipe; Described return pipe is arranged on the left of annular row water pipe, and return pipe right-hand member is provided with waterstop; Described slip casting country rock body is arranged on immediately below annular row water pipe.
As optimisation technique scheme of the present utility model: described feed pipe is connected with water knockout drum with return pipe, after fraction water device water-dividing, then flow ipe; Be welded and fixed and side by side arrangement by steelframe between described annular row water pipe, and ring pipe is circular.
Compared with prior art, the beneficial effects of the utility model are: take radial grouting, slip casting radius is large, slip casting effect is better, slurries are utilized to close water delivery crack and water burst space in basement rock, reduce country rock transmission coefficient, grouting blocking water ring is formed in cavern's surrounding, reach sealing object, run off for avoiding wet shot concrete cement paste and form cavity, rich water section adopts dry sprayig process, secondary lining self waterproofing is last one waterproof in tunnel, it is the mark in tunnel application life, crack and infiltration is there is in order to overcome the inner a large amount of capillary tube of ordinary concrete and gap, secondary lining adopts the C25 waterproof concrete of anti-penetration grade S8, water seal after lining cutting can be discharged in time, and be conducive to the hydrostatic pressing reducing secondary lining, drainage performance is more superior, partitioning waterproofing layer arranges and is beneficial to Tunnel Water Leakage regulation simultaneously, be beneficial to after tunnel puts into effect and keep in repair, there are good economic benefit and social benefit, practical, be applicable to promoting the use of.
