Abstract

The invention discloses a desk safety and inspection well, comprising well base (1) set at the bottom of inspection well, well cylinder, well seat (4) and well cover (6). Its well cylinder is divided into fixed well cylinder (2) and active well cylinder (3). The fixed well cylinder (2) is fixed on the well base (1) and presetting active well cylinder (3) is set on the fixed well cylinder (2) vertically. Pre-buried well ring (11) is set on the well seat (4), which is covered on the active well cylinder (3) flatly. Under the well cover (6) there is a desk (5), which covers on the active well seat (3). The well cover (6) is set in the well ring (11) of well seat (4). The well cover (6) and desk (5) are locked together by screw cap (3) and screw bar (9). The inspection well in the invention can solve the repairing problem when inspection well goes down or declines under pressure and the well cover is connected with the well seat by hinge so that it is opened freely and not easy to be stolen. Abnormal well cover is not easy to be turn out when it is extruded by wheel. If one well cover is lost, the reflectorized paint on the desk can take a caution to foot passenger or traveling crane so as to avoid the traffic accident.

Description

technical field [0001] The invention relates to a manhole well, in particular to a manhole inspection well in a drainage structure, and also to an inspection well for inspecting facilities such as underground pipelines, electric cables, and optical cables. Background technique [0002] The manhole covers of inspection wells such as traditional drainage inspection wells, rainwater inspection wells, and sewage inspection wells are basically round, square or rectangular. Circular manholes are the most widely used. However, traditional inspection wells often have disadvantages such as well bases sinking or tilting under pressure, manhole covers are easily squeezed out by wheels, and cast iron manhole covers are often stolen. These issues have long attracted people's attention. There are as many as thousands of Chinese patent applications involving inspection wells and manhole covers, among which there are 35 invention patents related to inspection well...
