Description

Technical Field

[0001] The utility model relates to the technical field of wellbore, in particular to a rainproof assembled wellbore open groove structure. Background Art

[0002] On the surface of the inclined shaft, due to the loose soil and more rainwater, a masonry structure is usually used to ensure the structural strength requirements and achieve a waterproof effect. The construction sequence is large excavation, masonry, and backfilling. The construction speed is slow and the cost is high. As an important connecting channel from the ground to the underground dark hole, the open trough is another structural type of coal mine inclined shaft located on the surface. Compared with the masonry structure, the open trough can effectively shorten the length of the dark hole, thereby shortening the underground escape distance; shortening the length of the underground pipeline; reducing costs; and improving the construction progress. However, the currently used open, cast-in-place reinforced concrete retaining wall open trough form has limited the promotion and use of open troughs due to rain protection issues and construction speed.

[0003] To this end, the present application designs a rainproof assembled open trench structure for a wellbore, which can achieve rainproofing of the open trench and at the same time improve the progress and safety of the open trench construction. Utility Model Content

[0014] (2) The open trench adopts prefabricated reinforced concrete structure and is assembled on site. Compared with cast-in-place concrete open trench, it has faster construction speed, simpler construction process, lower cost, and can shorten the start time of subsequent concealed trench construction, thereby improving the construction progress of the entire project.
