Description

Technical Field

[0001] The utility model relates to the technical field of temporary protection of roadbed slopes, in particular to a temporary drainage device for roadbed slopes. Background Art

[0002] The roadbed is a structure that directly supports the track formed by filling or excavation. During the operation of trains on high-speed railways, the roadbed bears the static load of the track and the live load of the train. Therefore, the roadbed is one of the important structures to ensure the safe operation of trains. During the filling period of the roadbed, it is inevitable to encounter rainy weather. In order to prevent rainwater from eroding the slope of the roadbed and affecting the integrity of the slope of the roadbed, it is necessary to set up temporary drainage devices on the slope of the roadbed.

[0003] The traditional temporary drainage device is an integrally formed rubber groove with a "U"-shaped cross-section. The construction method of the temporary drainage device is: first, a groove is manually excavated on the slope of the roadbed, and then the integrally formed rubber groove is directly buried in the groove, thereby guiding rainwater at the top of the slope into the drainage ditch at the foot of the slope through the rubber groove.

[0004] The above-mentioned temporary drainage device requires manual trench excavation during the construction process, which is bound to cause certain damage to the roadbed slope, not only affecting the auxiliary construction of the roadbed, but also the later repair of the roadbed slope also has the problems of large manual labor, time-consuming and labor-intensive, and low installation efficiency. On the other hand, the existing rubber groove is not easy to store during transportation due to its one-piece molding, and the transportation efficiency is low. It is easy to age due to the influence of the use environment, and the recycling cycle is short. In addition, due to its fixed overall structure, it cannot be adjusted for roadbed slopes of different lengths, resulting in poor adaptability. It is necessary to improve it. Utility Model Content

[0005] The utility model aims to solve the technical problems of the existing rubber grooves in the above background, such as the troublesome construction operation, low transportation and installation efficiency and poor adaptability, and proposes a temporary drainage device for the roadbed slope.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A temporary drainage device for a roadbed slope comprises a support top segment and a standard segment group, characterized in that: the support top segment is in the shape of an open groove, one end of the support top segment is a large-diameter end, and the other end of the support top segment is a small-diameter end, the large-diameter end of the support top segment is adapted to a water inlet at the top of the roadbed slope, and the large-diameter end and the small-diameter end of the support top segment cooperate with each other to guide rainwater to gather toward the small-diameter end; the small-diameter end of the support top segment is detachably assembled with a standard segment group through a connecting structure, the standard segment group is composed of a plurality of standard segments, and each standard segment is detachably connected end to end.

[0008] The connection structure includes a first fixing hole opened on the top segment of the support and a second fixing hole opened on the standard segment. The first fixing holes are arranged in an array on the inner plane of the top segment of the support, and the second fixing holes corresponding to the first fixing holes are arranged in an array on the inner plane of the standard segment. Fixing nails can be inserted into the first fixing holes and the second fixing holes.

[0009] The fixing nail is in the shape of an elongated cylinder, one end of the fixing nail is in the shape of a pointed cone, and a limiting flange is arranged at the other end of the fixing nail, and the diameter of the limiting flange is larger than the first fixing hole and the second fixing hole.

[0010] The cross section of the upper half of the support top segment is trapezoidal, and the cross section of the lower half of the support top segment is rectangular.

[0011] The standard segment is in the shape of a rectangular open slot.

[0012] The connection structure includes a first external assembly slot arranged on both sides of the small-diameter end of the top segment of the support, an internal assembly slot arranged on both sides of one end of the standard segment, and a second external assembly slot opened on both sides of one end of the standard segment. The first external assembly slot and the second external assembly slot have the same structure, and the internal assembly slot is matched with the first external assembly slot and the second external assembly slot for card connection.
