Description
Technical field
The utility model relates to tunnel-like, relates in particular to a kind of totally-enclosed waterproof composite lining structure of adjustable water saving pressure, is specially adapted to the construction of tunnel that water level is big with seasonal variations and underground current are lost sensitivity.
Background technology
Along with China's infrastructure is built on a large scale; underground constructions such as large-scale mountain tunnel, leap rivers, chunnel are greatly developed; the hydrogeological conditions that construction of tunnel ran into also becomes increasingly complex; environmental protection requirement is also more and more higher, how rationally to handle the concern that phreatic emission problem also more and more is subjected to each side in the design.At present according to phreatic emission treatment mode is divided into two types with the combined type tunnel lining structure, a kind of is the dewatering type lining cutting, promptly all underground water that enter preliminary bracing inboard, tunnel are all by the tunnel drainage system discharging, and secondary lining does not bear water pressure; Another kind is the water proof type lining cutting, does not promptly discharge underground water fully, and secondary lining need bear the maximum water pressure in the whole operation phase of tunnel.The dewatering type lining cutting can only be applicable to that ground environment loses insensitive area to underground current; The water proof type lining cutting is owing to need bear high hydraulic pressure in the tunnel operation phase, thereby generally can only be applicable to area about the about 100m of maximal head, when water pressure was higher, the water proof type lining cutting needed very big structural thickness, causes structural design scheme infeasible or very uneconomical.In the engineering practice process, often run into this type of situation: river that the subaqueous tunnel passes through such as river, Liuyang, middle and upper reaches section, the Changjiang river etc., SEA LEVEL VARIATION is very big in its year, and peak level and lowest water level differ 10～20m; Build the tunnel at karst area, groundwater table is generally lower, but water level rises suddenly during heavy rain.Under this kind situation, as adopting the water proof type lining cutting, need to press the high water level design, the structural thickness that needs is big, and engineering is uneconomical.As adopt the totally-enclosed waterproof composite lining structure of adjustable water saving pressure, the requirement of water pressure when then structure can only satisfy ordinary water level, when water level raises, can carry out draining by Open valve, make that structure is unlikely bears too high water pressure, draining simultaneously can not produce the significant adverse influence to underground water environment yet.
The utility model content
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, provide a kind of simple in structure, easy construction, the totally-enclosed waterproof composite lining structure of reliable quality is adjustable water saving pressure, make it need not bear the high hydraulic pressure that occurs in short-term in the tunnel operation phase, guarantee the safety of liner structure, reach favorable economic benefit.
The realization of the utility model purpose is finished by following technical scheme: a kind of totally-enclosed waterproof composite lining structure of adjustable water saving pressure, comprise arch wall and inverted arch, and arch wall is combined by arch wall preliminary bracing 1, arch wall splash guard 2 and arch wall secondary lining 3; Inverted arch is combined by inverted arch preliminary bracing 4, inverted arch splash guard 5 and inverted arch secondary lining 6, it is characterized in that, in the tunnel, be higher than between the preliminary bracing of central ditch or waste water pump house position and the splash guard longitudinal drainage blind pipe is set, be furnished with aperture on the tube wall of this blind pipe, penetrate secondary lining by transverse connecting pipe and introduce central ditch or waste water pump house in the tunnel, simultaneously, setting pressure table and valve in transverse connecting pipe.
Furtherly, described longitudinal drainage blind pipe can be arranged between arch wall preliminary bracing and the arch wall splash guard.
Furtherly, described longitudinal drainage blind pipe is preferably disposed on the foundation position between arch wall and the inverted arch, between arch wall preliminary bracing and arch wall splash guard.
In such scheme, the described aperture that is arranged on the longitudinal drainage blind pipe vertically is mesh-shape along blind pipe and arranges.
In such scheme, described splash guard is preferably the macromolecule composite self-adhering water-proof coiled material.
In such scheme, described inverted arch splash guard and arch wall splash guard preferably are connected as a single entity and constitute the loopful waterproof construction.
The utility model is on the basis of totally-enclosed waterproof composite lining structure, can regulate the purpose that the device of water pressure reaches the control water pressure by a cover is set.Be specially: the longitudinal drainage blind pipe is set, central ditch or the waste water pump house of this blind pipe the appropriate location, tunnel penetrates secondary lining introducing tunnel by transverse connecting pipe between supporting in the early stage and the secondary lining.Simultaneously, at the easy maintenance position setting pressure table and the valve of transverse connecting pipe.In the operation process, the pressure size of observed pressure table (can adopt the automatic monitoring mode), the water pressure that shows as pressure meter are opened valve (can adopt automation control) during near the water pressure considered in advance, underground water is entered ditch or waste water pump house in the tunnel, to reduce water pressure.
This composite lining structure is a kind of totally enclosed waterproof construction, can bear certain water pressure, the head in the lining cutting of tunnel recombination formula can be regulated according to the pressure size that records, when pressure is excessive, the pressure release that can discharge water by the valve in the tunnel guarantees the safety of liner structure.The utility model need not be born the high hydraulic pressure that occurs in short-term in the tunnel operation phase, reach favorable economic benefit, simple in structure, easy construction, reliable in quality, be applicable to underground current are lost responsive construction of tunnel design, be specially adapted to water level and lose responsive construction of tunnel design greatly and to underground current with seasonal variations.
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that colleague technician's understanding.
