Abstract
The invention aims at providing a pressure-proof structure of an underground tunnel. The pressure-proof structure can be used for effectively reducing external water pressure on the tunnel and effectively improving the pressure-proof capacity of the tunnel. According to the technical scheme, the pressure-proof structure of the underground tunnel comprises the tunnel, a water drain region connected to the periphery of the tunnel in a sleeving manner, longitudinal water drain pipes arranged at the lower part of the outer wall of the tunnel along the axial direction of the tunnel and annular water drain pipes arranged around the periphery of the tunnel, wherein at least one water drain pipe is arranged in the water drain region and is communicated with the annular water drain pipes; each annular water drain pipe is communicated with the corresponding longitudinal water drain pipe. Permeated water can be collected by the water drainage pipes, is gathered to the annular water drain pipes in sequence and is drained by the longitudinal water drain pipes. Therefore the permeated water can be drained away in time, and the water pressure on the tunnel can be effectively reduced, so that the pressure-proof capacity of the underground tunnel is effectively improved. The pressure-proof structure of the underground tunnel is particularly suitable for the building of underground tunnels under higher water pressure.
Description
Technical field
The present invention relates to water conservancy and hydropower building field, especially a kind of subterranean tunnel compression-resistant structure.
Background technology
In the building of Hydropower Dam, need to build accordingly buried in the tunnel of underground in a large number.Subterranean tunnel affects by underground high water level or endochronic model affects, tunnel in hole anhydrous or internal water pressure is less time bear comparatively large outer water ballast(ing), for ensureing tunnel structure safety, usual employing adopts consolidation grouting to improve ground globality and impermeability to the outer rock stratum of tunnel or soil layer, but, such mode also strengthens the mode of physical dimension and arrangement of reinforcement while improving globality and impermeability, certainly will cause the increase of excavated volume, amount of concrete, reinforcing bar amount, be unfavorable for energy-saving and emission-reduction.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of effectively reduction tunnel external water pressure, thus effectively improves the subterranean tunnel compression-resistant structure of tunnel anti-pressure ability.
The technical solution adopted for the present invention to solve the technical problems is: subterranean tunnel compression-resistant structure, comprise tunnel and be socketed on the catchment of tunnel periphery, the axis direction also comprised along tunnel is arranged at the longitudinal drainage pipe of the bottom of the outer wall of tunnel, and around tunnel periphery arrange ring direction drainpipe, at least one gutter is provided with in catchment, described gutter communicates with ring direction drainpipe, and each ring direction drainpipe is all communicated with longitudinal drainage pipe.
Further, comprise the top and the unidirectional flow device of connection tunnel and ring direction drainpipe that are arranged at tunnel, the flow direction of described unidirectional flow device flows to tunnel by ring direction drainpipe.
Further, described unidirectional flow device is one way valve or electrically-controlled valve.
Further, comprise consolidation grouting district, described consolidation grouting district is socketed on the periphery of catchment.
Further, the structure that is integrated of described catchment and consolidation grouting district.
Further, described gutter is four, and is distributed in catchment.
The invention has the beneficial effects as follows: when reality uses, once there is the situation that outer water infiltrates, namely the outer water infiltrated can be collected by gutter, and converge to ring direction drainpipe successively, then drained by longitudinal drainage pipe.So not only timely infiltration can be drained, also can effectively reduce the pressure of hydraulic pressure to tunnel, so effectively raise the anti-pressure ability of subterranean tunnel.The present invention is particularly useful in building of the larger subterranean tunnel of hydraulic pressure.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
Subterranean tunnel compression-resistant structure as shown in Figure 1 and Figure 2, comprise tunnel 1 and be socketed on the catchment 2 of tunnel 1 periphery, the axis direction also comprised along tunnel 1 is arranged at the longitudinal drainage pipe 14 of the bottom of the outer wall of tunnel 1, and around tunnel 1 periphery arrange ring direction drainpipe 13, at least one gutter 21 is provided with in catchment 2, described gutter 21 communicates with ring direction drainpipe 13, and each ring direction drainpipe 13 is all communicated with longitudinal drainage pipe 14.
When practical application, in order to reduce the hydraulic pressure of outer water to tunnel 1, present invention employs and outer water is effectively drained, thus reduce the method for outer water ballast(ing).Particularly, when outer water permeation is to catchment 2, can converge under the effect of hydraulic pressure in gutter 21, and along with the water yield increase stored in gutter 21, water in described gutter 21 can flow to ring direction drainpipe 13 place and further collect, the water storage of ring direction drainpipe 13 is then directly drained by longitudinal drainage pipe 14, general, and the draining of longitudinal drainage pipe 14 can consider the direction along current downstream in tunnel 1.
In order to realize the flexible control to above-mentioned draining, such scheme can be selected: comprise the top and the unidirectional flow device 11 of connection tunnel 1 and ring direction drainpipe 13 that are arranged at tunnel 1, the flow direction of described unidirectional flow device 11 flows to tunnel 1 by ring direction drainpipe 13.As shown in Figure 1, general, groundwater table height H 3 is all greater than height of water level H2 in tunnel height H 1 and tunnel.When tunnel height H 1 is less than height of water level H2 in tunnel, above-mentioned outer water is drained by means of only gutter 21, ring direction drainpipe 13 and longitudinal drainage pipe 14.But, when tunnel height H 1 is greater than height of water level H2 in tunnel, namely the outer water be stored in ring direction drainpipe 13 flow in tunnel 1 by unidirectional flow device 11, thus strengthen the discharge efficiency of outer water greatly, reduce the hydraulic pressure of outer water, make structure of the present invention more firm.In conjunction with the engineering experience of practice, can unidirectional flow device 11 be preferably generally one way valve or electrically-controlled valve.
In order to further reduce the infiltration of outer water, thus further reduce the hydraulic pressure of outer water, can select to set up consolidation grouting district 3, described consolidation grouting district 3 is socketed on the periphery of catchment 2.As depicted in figs. 1 and 2, when being in the milk, suitably improve the pressure of grouting, by the hole in the ground in slurry plugs consolidation grouting district 3, improve globality and the impermeability of this region ground, reduce in outer water and ooze passage, effectively reduce outer water permeation pressure and water percolating capacity to reach.General, when practice of construction, described catchment 2 can be selected to be designed to structure integrally with consolidation grouting district 3.
Certain, in order to effectively realize the discharge of outer water, can preferred gutter 21 be generally four, and being distributed in catchment 2.As shown in Figure 1, like this can comparatively balanced outer water be discharged, effectively reduce the hydraulic pressure of outer water, thus better raising tunnel anti-pressure ability.
