Description
Technical field
The utility model relates to tunnel counter-slope technical field of drainage, relates in particular to a kind of tunnel counter-slope and to draw water refining plant.
Background technology
Along with traffic and Hydraulic and Hydro-Power Engineering build center of gravity to the extreme complicated western mountainous areas of topographic and geologic condition and karst region transfer, by a collection of profound Tunnel Engineering of excessive risk with distinguishing features such as " great burying, Chang Dongxian, heavily stressed, strong karst, high hydraulic pressure, complex structure, disaster take place frequently " of appearance.In highway communication field, profound tunnel is the throat of traffic engineering, is the lifeline engineering being related to society and Development of Economy.In the last few years, further obvious by the construct technological challenge that brings of long distance counter-slope, the construction time geologic hazards such as the gushing water water burst therefore caused constantly occur, as: Hubei expressway from Shanghai to Chendu Qiyueshan Tunnel outlet paragraph because counter-slope is constructed, meeting with large-scale water burst accident when passing through underground river, underground, manger hole and super large tomography, because water exhaust system is limited in one's ability, causing being submerged more than the barrel of 700m, construction delay was more than 1 year, and financial loss is serious.Hubei expressway from Shanghai to Chendu Longtan Tunnel exit end is the construction of long distance counter-slope, and meet with when passing through the fault belt of 700m length and gush mud water burst, plumbing brings huge difficulty.At railway territory, for the mountain railway of the most difficult construction in the world--Yichang-Wanzhou Railway, there is the counter-slope construction paragraph of longer distance in its Maluqing tunnel, successively there are 19 serious gushing waters in construction to dash forward mud disaster, instantaneously the world's railway construction of prominent water yield wound, wherein on January 21st, 2006 and twice water bursting on April 11st, 2008 mud disaster of dashing forward causes 15 people's death altogether.And Wuqiaoling tunnel also exists the counter-slope construction area of longer paragraph in construction, the design for water exhaust system brings huge challenge.
As from the foregoing, the tunnel disaster that water burst brings of dashing forward is of common occurrence, how can just avoid the generation of these accidents? when there is prominent water burst, water-pumping/draining operation fast and effectively, Accidents Disasters can be avoided to occur, reduce unnecessary personnel and financial loss, ensure the normal construction in tunnel.On the preparation of construction and conceptual design of draining, an efficient pumping plant water-pumping/draining system, often determines the one-tenth of water-pumping/draining construction and loses, also affecting the safety in production of engineering project.
Current tunnel drainage pumping plant technology has " a kind of water-freeing arrangement and water discharge method growing distance reverse-slope tunnel " (201210112312.2), the method arranges a precipitation cavern and a pumping plant cavern in every one-level simultaneously, with the blocking avoiding pipeline to cause due to dirt accumulation, but due to Liang Ge cavern will be excavated, workload is large, and cost is higher; Multiple water-level probe is arranged in " automatic drainage system for cable tunnel " (200810137337.1) on pump well, but catchment when reaching high-water, start submersible pump and carry out draining, but the drainage effect that the method is directed to the little water yield is better, inapplicable for big yield, for a long time monitoring draining in tunnel; " a kind of experimental installation of simulating Limestone pavement tunneling drain calcium carbonate crystal rule " (201410484203.2) provide a kind of experimental installation of excellent property, improve shelf life and the reliability of Limestone pavement tunnel drainage system, but it is studied calcium carbonate crystal, specific aim is comparatively strong, can not be applicable to other lithology tunnels; Water by the pump well that to be first extracted into by the water in tunnel with water pump in inclined shaft, then is extracted out outside hole by the water pump in pump well by " a kind of super long tunnel water exhaust system " (201220694226.2), ignores tunnel mud stopping state; " a kind of tunnel props up hole counter-slope water exhaust system " (201420630003.9), silt in water-pumping/draining process is reduced by arranging settling pit below pump well, ensure pump working, shortcoming is that settling pit adds excavation construction amount, if settling pit mud overheap simultaneously, because its degree of depth is comparatively large, not easily desilting.
In general, current existing water-freeing arrangement has following Railway Project:
1. pumping for water pump blockage.Due in constructing tunnel process, water, in the process collected, can carry a large amount of channerys or rubbish incidental, in the process of pumping for water pump, very easily block pumping for water pump pipe, causes the operation of water pump water-pumping/draining to lose efficacy; Build settling pit according to ordinary method, then can increase construction cost and workload, cost is higher, therefore needs badly and proposes a kind of water-pumping/draining technology that can effectively avoid pump mouth to block;
2. drainage effect gets half the result with twice the effort.Current tunnel drainage facility needs assistant director to manage, when carrying out draining, draining assistant director is needed to judge water yield, Non-follow control water pump carries out draining again, its maneuvering ability is poor, when running into emergency case, draining and early warning can not be carried out fast and effectively, easily causing tunnel by the generation of situations such as flooding.Now need badly and develop a kind of water-pumping/draining and water yield early-warning equipment automatically;
3. water resource waste.In the construction process in tunnel, from working face drill two lining construction, and even tunnel spray control airborne dust, all need diversion from hole, if waste water in tunnel pump well can be carried out evolution process, again utilize, can not only saving water resource, also can reduce the transportation cost of water resources; Therefore need a kind of device that can carry out original position Water warfare and utilization of development badly.
