[0002] In the current drainage industry, in terms of the construction of drainage pipe networks, such as the construction of urban municipal underground pipe networks, culvert pipe networks, pipe networks across obstacles or walls, precast concrete module inspection wells, etc. Inspection wells are set up for the maintenance of power supply, water supply, drainage, sewage discharge, communication, cable TV, gas pipes, street lamp lines, etc. of urban underground infrastructure. They are generally located at pipe intersections, turning points, where the pipe diameter or slope changes, and at certain intervals on straight pipe sections. They are auxiliary structures for facilitating regular inspections. However, the current inspection wells generally have a general connection effect in terms of structure and have a low load capacity, which brings certain limitations to the use of inspection wells. Content of the Utility Model

[0003] The purpose of the utility model is to provide an inspection well for drainage, which has more vertical load-bearing capacity compared with the existing inspection wells, improves the scope of use and service life of the inspection well, realizes the connection stability between the inspection well and external pipes, and reduces the inconvenience caused by easy detachment.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions: An inspection well for drainage includes a wellhead. A pipe cavity is provided at the bottom of the wellhead. Connecting pipes are provided on both sides of the pipe cavity. An outer ring rib two is fixedly sleeved on the surface of the connecting pipe. An outer ring rib three is fixedly sleeved on the surface of the pipe cavity. Reinforcing ribs fixedly connected to the outer ring rib three are fixedly installed on the surface of the pipe cavity.

[0005] By adopting the above technical solutions: When using the inspection well for drainage, the connection between the wellhead and the pipe cavity can be ensured through a connecting piece one. The outer ring rib one increases the anti-slip property and hardness of the wellhead surface. The external pipe is connected and sleeved with the connecting pipe. The connecting pipe is four centimeters longer than the current national standard inspection well pipe orifice, which is more convenient for the socket installation with the external pipe. And the outer ring rib two increases the anti-slip property and hardness of the connecting pipe surface. The outer ring rib three increases the anti-slip property and hardness of the pipe cavity surface. At the same time, the longitudinal distribution of the reinforcing ribs can increase the load of the pipe cavity. Compared with the existing inspection wells, it has more vertical load-bearing capacity, improves the scope of use and service life of the inspection well.

[0006] The utility model is further arranged such that a connecting piece one is provided for mutual connection and communication between the wellhead and the pipe cavity.

[0007] By adopting the above technical solutions: The connection and communication between the wellhead and the pipe cavity are ensured through the connecting piece one.

[0008] The present utility model is further configured such that a second connecting member is communicatively connected between the connecting pipe and the pipe cavity.

[0009] By adopting the above technical solution: the communication between the connecting pipe and the pipe cavity is ensured by the second connecting member.

[0010] The present utility model is further configured such that an outer ring rib one is fixedly sleeved on the surface of the wellhead.

[0011] By adopting the above technical solution: the anti-slip property and hardness of the wellhead surface are increased by the outer ring rib one.

[0012] The present utility model is further configured such that the reinforcing ribs are longitudinally distributed.

[0013] By adopting the above technical solution: the load of the pipe cavity can be increased by the longitudinal distribution of the reinforcing ribs.

[0014] In summary, the present utility model has the following beneficial effects:

[0015] When the present utility model is used for the inspection well for drainage, the outer ring rib one increases the anti-slip property and hardness of the wellhead surface. The external pipe is connected and sleeved with the connecting pipe, and the connecting pipe is extended by four centimeters compared with the current national standard inspection well pipe orifice, which will be more convenient for the socket installation with the external pipe. And the outer ring rib two increases the anti-slip property and hardness of the connecting pipe surface, the outer ring rib three increases the anti-slip property and hardness of the pipe cavity surface, and at the same time, the longitudinal distribution of the reinforcing ribs can increase the load of the pipe cavity. Compared with the existing inspection wells, it has stronger vertical load capacity, improving the application range and service life of the inspection well. BRIEF DESCRIPTION OF THE DRAWINGS
