SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the above-mentioned shortcoming of prior art, provide a shell drain bar for railway tunnel.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a shell drain bar for railway tunnels, comprising: the device comprises a substrate and a bracket, wherein one side of the substrate is provided with a plurality of grooves and bulges towards the other side to form a bulge; the support includes first connecting pipe and second connecting pipe, first connecting pipe with the crossing and mutual fixed connection of second connecting pipe form a cross structure, first connecting pipe with the second connecting pipe intercommunication, the both ends of first connecting pipe the inner wall fixed connection of recess link up extremely bellied outer wall, the both ends of second connecting pipe with the inner wall fixed connection of recess link up extremely bellied outer wall.
Furthermore, the groove bottom of the groove is planar and parallel to the substrate, the axis of the first connecting pipe is parallel to the substrate, and the axis of the second connecting pipe is parallel to the substrate.
Further, the axis of the first connecting pipe and the axis of the second connecting pipe intersect and are perpendicular.
Further, the distance from the axis of the first connecting pipe to the bottom of the groove is a, the distance from the axis of the first connecting pipe to the base plate is b, and the ratio of a to b is 1.5.
Further, the protrusions are distributed on the substrate in a matrix manner.
Furthermore, the electric wire drawing machine further comprises a dredging line, the dredging line sequentially penetrates through the first connecting pipes and is connected end to form a closed coil, and the dredging line is provided with a driving plate.
Compared with the prior art, the utility model provides a pair of shell drain bar for railway tunnel has following beneficial effect:
1. the support is arranged, so that the drainage plate has better pressure resistance, and the bulge is not easy to deform and damage;
2. the arrangement of the first connecting pipe and the second connecting pipe increases the drainage performance;
3. the arrangement of the dredging line prevents the first connecting pipe from being blocked.
Drawings
Fig. 1 is a bottom view of an embodiment of the present application.
Fig. 2 is a top view of an embodiment of the present application.
Fig. 3 is a partial cross-sectional view of an embodiment of the present application.
In the figure: the device comprises a base plate 1, a groove 2, a protrusion 3, a support 4, a first connecting pipe 5, a second connecting pipe 6, a dredging line 7 and a driving plate 8.
Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Referring to fig. 1 to 3, a shell drain board for a railway tunnel includes: the device comprises a substrate 1, a support 4 and a dredging line 7, wherein a plurality of grooves 2 are formed in one side of the substrate 1, and bulges towards the other side to form a bulge 3;
support 4 includes first connecting pipe 5 and second connecting pipe 6, first connecting pipe 5 with second connecting pipe 6 is crossing and mutual fixed connection forms a cross structure, first connecting pipe 5 with second connecting pipe 6 intercommunication, the both ends of first connecting pipe 5 with the inner wall fixed connection of recess 2 link up extremely bellied outer wall, the both ends of second connecting pipe 6 with the inner wall fixed connection of recess 2 link up extremely bellied outer wall.
The tank bottom of recess 2 is planar and with base plate 1 is parallel, the axis of first connecting pipe 5 with base plate 1 is parallel, the axis of second connecting pipe 6 with base plate 1 is parallel.
The axis of the first connecting pipe 5 and the axis of the second connecting pipe 6 intersect and are perpendicular.
The distance from the axis of the first connecting pipe 5 to the bottom of the groove 2 is a, the distance from the axis of the first connecting pipe 5 to the base plate 1 is b, and the ratio of a to b is 1.5.
The protrusions 3 are distributed in a matrix on the substrate 1.
The dredging line 7 sequentially penetrates through the first connecting pipes 5 and is connected end to form a closed coil, and the dredging line 7 is provided with a driving plate 8.
Principle of embodiment:
through setting up support 4 to the hole that has increased protruding 3 presses the performance, when the soil layer covers in the upside of protruding 3, protruding 3 is difficult to take place to destroy and the deformation. Thereby ensuring the normal operation of the drain board. Simultaneously, first connecting pipe 5 and second connecting pipe 6 also possess the function of drainage, and rivers can pass from first connecting pipe 5 and second connecting pipe 6, and then improve the drainage performance of drain bar. The dredging line 7 penetrates through the first connecting pipe 5, when water flows through the driving plate 8, the driving plate 8 drives the dredging line 7 to move, and when soil particles exist in the first connecting pipe 5, the dredging line 7 moves to dredge the first connecting pipe 5, so that the first connecting pipe 5 is prevented from being blocked.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are considered to be within the scope of the invention as defined by the following claims.
