Abstract

The invention belongs to the technical field of drainage of underground concealed conduits, and particularly relates to an underground drainage concealed conduit connecting device. The underground drainage concealed conduit connecting device comprises a connecting tube section which is used for accommodating a corrugated plastic drainage concealed conduit; blocking teeth which are blocked with trough grooves of the corrugated plastic drainage concealed conduit are arranged in positions, in the peripheral direction of the connecting tube section, close to the two ends of the connecting tube section; and a limiting bump for limiting an insertion position of the corrugated plastic drainage concealed conduit is arranged on a position, in the peripheral direction of the connecting tube section and facing towards the inner wall of the connecting tube section, on the middle of the connecting tube section. The underground drainage concealed conduit connecting device has the advantages of being simple to operate, quick in connection, good in connecting quality, free of stoppage of construction and the like, and can greatly improve mechanical construction efficiency and quality of the plastic drainage concealed conduit.

Description

technical field [0001] The invention belongs to the technical field of underground drainage, in particular to an underground drainage connection device. Background technique [0002] Farmland underground pipe drainage technology is an effective measure for land drainage, prevention of salinization of irrigated land, and transformation of low-yield fields. Compared with open ditch drainage, it has the characteristics of better drainage effect, effective control of groundwater level, saving land, and reducing maintenance costs. Underground pipe drainage has a long history of application in our country. In the previous practice of underground pipe drainage, obvious effects of drainage and salt reduction have been achieved. However, such an experience has also been summed up: that is, the large-scale promotion of underground pipe drainage technology must use modern pipe-laying machinery for mechanized construction, so as to ensure the construction quality and reduce the cost. ...
