Abstract
The utility model relates to a drainage structure at the position of a tunnel deformation seam, which is characterized in that an annular drainage pipe is arranged along the outer side of a tunnel and a soil facing side of the deformation seam and connected with a longitudinal drainage pipe arranged at the bottom of the tunnel, and the longitudinal drainage pipe is connected with a horizontal drainage pipe. Ground water penetrating along the deformation seam is gathered in the longitudinal drainage pipe through the annular drainage pipe, and similarly the ground water at the position of each deformation seam is gathered into the position of the lowest elevation along a central drainage pipe and then led in a drainage pump chamber through the horizontal drainage pipe. The drainage structure at the position of the tunnel deformation seam has the advantage that the annular drainage pipe is arranged on the outer side along the tunnel and the soil facing side of the deformation seam of a buried section, infiltration passages of the ground water accumulated at the positions of the deformation seams are cut off, the amount of the ground water at the positions of the deformation seams can be reduced greatly, and pressure of the ground water can be reduced greatly.
Description
Technical field
It is genuine along the practice that the utility model relates to open cut, specifically a kind of secretly discharge structure of the section of burying deformation joint of tunnel that is used for.
Background technology
The survey showed that according to the genuine percolating water that has built up at present: genuine percolating water multidigit is in deformation joint, especially secretly the section of burying deformation joint.
Current specifications and present common practice: the suitable practice tunnel of the open cut secretly section of burying deformation joint all adopts " blocking up " to be main thought, and it is master's waterproof system that the measures such as middle buried water stop, external labeling type waterstop that promptly are provided with form with " preventing ".But show along the genuine operation situation of the practice according to the open cut of having built up: a considerable amount of tunnels after operation secretly the section of burying deformation joint percolating water phenomenon in various degree all appears, not only operation security is formed hidden danger, and is unfavorable for structure durability.
Summary of the invention
The purpose of the utility model is to provide a kind of secretly drainaging scheme of the section of burying deformation joint percolating water of the suitable practice tunnel of open cut that reduces, and promptly on the basis of " blocking up ", has increased the measure of " row ", thereby has reduced the possibility of deformation joint groundwater seepage greatly.
To achieve these goals; The technical scheme of the utility model is: a kind of genuine deformation joint discharge structure; It is characterized in that: meet native side along genuine arranged outside ring direction drainpipe along deformation joint; Ring direction drainpipe is connected with the longitudinal drainage pipe that genuine bottom is set, and the longitudinal drainage pipe is connected with transverse drain.The tunnel comprises top board, base plate and both sides side wall; Wherein the top board end face is provided with the low open roof in high both sides, center along deformation joint; The base plate bottom surface then is provided with the high open roof in low both sides, center along deformation joint; Ring direction drainpipe is provided with along top board end face, both sides side wall and base plate bottom surface, and the longitudinal drainage pipe is arranged on the base plate center, and is positioned at the ring direction drainpipe below.Genuine base plate has concrete cushion, and ring direction drainpipe is arranged between concrete cushion and the genuine base plate, and the longitudinal drainage pipe is arranged in the concrete cushion, is provided with the sand gravel filtrate between longitudinal drainage pipe and the ring direction drainpipe.Be provided with a plurality of deformation joints along the tunnel, so this discharge structure comprises a plurality of ring direction drainpipes, these a plurality of ring direction drainpipes all are connected with the longitudinal drainage pipe, and these longitudinal drainage pipe two ends are high, and middle low, transverse drain is arranged on longitudinal drainage pipe minimum point.For the ease of getting rid of top board and base plate place underground water, genuine top board end face is provided with the gradient and is not less than 0.5% open roof, and the base plate bottom surface is provided with the gradient and is not less than 0.5% the open roof that falls.
Underground water along the deformation joint infiltration imports the longitudinal drainage pipe through ring direction drainpipe, and in like manner each deformation joint underground water all imports the lowest bid eminence along central drainage pipe, introduces the draining pump house by transverse drain then.The advantage of the utility model is through meeting native side along genuine arranged outside ring direction drainpipe along the section of burying deformation joint secretly; Thereby cut off the path that oozes under the underground water that deformation joint gathers; The phreatic water yield of deformation joint can be significantly reduced on the one hand, phreatic pressure can be reduced greatly on the other hand.
