Problems solved by technology

[0006] The present invention overcomes the need to destroy the sealant or cement during maintenance and other operations in the cableman’s well with multi-cover seals in the prior art, and secondary sealing is required after the maintenance and other operations. To solve the technical problem of waste, a waterproof cable well is provided, which prevents rainfall and water seepage through the cover plate in the form of a snap-in buckle. Good waterproof protection, in addition, there is no need to destroy or rebuild the seal during maintenance and other operations, greatly improving the convenience of maintenance operations

Embodiment 1

[0031] Such as Figure 1 to Figure 5As shown, a waterproof cable well includes a well body 1 and a well cover 2. The opening end of the well body is provided with a well edge 3 for supporting the well cover. The well cover includes several spliced ​​and matched cover plates 4. The cover plate includes The main body 401 and the supporting member 402, and the two supporting members with similar positions on the adjacent two cover plates are overlapped up and down, and the edge of the working well is provided with a water accumulation groove 5 and a drainage hole 6, and a water collecting well is provided in the working well body. The bottom of the water collection well is provided with a sealing layer; the cover plate includes an end cover plate 7 and a middle cover plate 8, and the end cover plate includes a first body 701 and a first support member 702, and the first support member is located at the first body away from the working well. On one side of the edge, the middle cov...

Embodiment 2

[0035] In this embodiment, a locking piece is added between the end cover plate and the edge of the well to improve the anti-theft protection of the cable. The traditional locking piece adopts an open lock structure. Although the above-mentioned locking piece is easy to open, the anti-theft function of the well cover has declined. In order to enhance the anti-theft function of the manhole cover, this embodiment provides a built-in lock structure, the locking member is arranged between the end cover plate and the edge of the work well, and the first lock groove 11 is opened on the right end surface of the first body, and the edge of the work well There is a second lock groove 12 on the top. When the end cover is in the closed state, the first lock groove and the second lock groove are aligned. The locking part includes a lock cylinder 13, a limiting part 14, a reset part 15 and a reset airbag 16. The lock cylinder includes a lock cylinder body 131 on the left side and a slider ...

Abstract

The invention provides a waterproof cable working well in order to solve the technical problems that in the prior art, when a cable working well sealed by multiple cover plates is overhauled and the like, sealant or cement needs to be damaged, secondary sealing needs to be carried out after overhauling and other operation are finished, time and labor are consumed in the overhauling operation, and sealing materials are prone to being wasted. The waterproof cable working well comprises a working well body and a well lid; a working well edge used for supporting the well lid is arranged at the opening end of the working well body; the well lid comprises a plurality of cover plates which are spliced and matched; each cover plate comprises a body and supporting pieces; the two supporting pieces, close in position, on every two adjacent cover plates are in lap joint in a vertically staggered manner; a water accumulation groove and a drainage hole are formed in the edge of the working well; a water collecting well is arranged in the working well body; and a sealing layer is arranged at the bottom of the water collecting well. According to the waterproof cable working well, rainfall water seepage is prevented through the cover plates in a snap fastener lap joint manner, seepage water is drained in time through the water accumulation groove and the drainage hole in the edge of the well lid of the working well, and good waterproof protection is formed for the cable working well through the dual structure.

Description

technical field [0001] The invention relates to the technical field of cable wells, in particular to a waterproof cable well. Background technique [0002] According to the laying requirements of power cables, a cable inspection well or branch well (collectively referred to as cable wells) shall be installed at a certain distance along the length of the path (generally no more than 100m). According to the requirements of maintenance, the inner clearance height of the well shall not be less than 1.9m, plus the thickness of the attached soil and the roof, the water and soil pressure on the outer wall in the soft soil area may exceed 20kN / m2, so the well The structural design is one of the main technical issues. The problem is that in some areas with heavy rainfall and abundant groundwater resources, most of the high-voltage cable wells have serious water accumulation. If the high-voltage cables run in the water-logged environment for a long time, water will enter the high-vol...
