The second pipe body 200 and the shaft 100 are connected through hot melting by adopting the same material as the shaft, so that the sealing performance is improved.

The wellbore 100 is made using a winding process, but is not limited thereto, for example, in some applications, the wellbore 100 may use MUHDPE wound structural wall a-tubes that perform the group standard T/GDC 29-2019; HDPE winding structure wall A type pipe implements national standard GB/T19472.2-2017. Hereinafter referred to as MUHDPE pipe and HDPE pipe. The rigidity of the MUHDPE pipe ring can reach 20KN/m²The rigidity of HDPE pipe ring is generally 6KN/m². The requirement of the impact property of the MUHDPE pipe is higher than that of the HDPE pipe, the impact height smaller than DN500 is 1000mm, the impact height larger than or equal to DN500 is 2000mm, and the mass of the impact hammer is uniformly 5 KG. The requirement of the ring flexibility of the MUHDPE pipe is higher than that of the HDPE pipe, the deformation amount of the flexible outer diameter of the HDPE pipe ring is 30%, and the deformation amount of the flexible outer diameter of the MUHDPE pipe ring is 40%. One more technical parameter of MUHDPE pipes is the recovery rate. The outer diameter of the pipe is deformed by 30 percent and unloaded, and can be recovered by 95 percent or more after 2 hours. Therefore, more preferably, MUHDPE pipe is used.

The height of the solid wall 101 is 3-20cm, but is not limited thereto, and the height of the solid wall may be selected according to the specific implementation.

Also included is a bottom plate 400 that is bolted to the solid wall of the wellbore 100, which arrangement improves safety during normal use.

The bottom plate 400 and the second pipe 200 are welded firmly, smoothly and smoothly without leakage. Wellbore 100 employs PP tubing stiffeners. Other requirements are detailed in the standard CJ/T326-2010, the second tube is detailed in the standard GB/T19472.2-2017, and in FIGS. 9-10, the second tube 200 located inside the shaft 100 is provided with a flow groove 201 for communicating with the shaft 100.

Specifically, because the connection mode of the winding structure wall A-shaped pipe in the current market mostly adopts flaring, heat shrinkage sleeve, stainless steel clamping ring, hot melting joint and the like for connection, the water leakage phenomenon exists in all the pipes, and the connection is not reliable. (1) The flaring connection needs to perform secondary heating on the pipe and then expand from inside to outside to form a pipe bell mouth, the flaring process is the process of pipe deformation, the structure of the bell mouth is damaged, the inner surface of the bell mouth is rough and not smooth, in addition, the inclination of the flaring is large, water leakage can occur when the bell mouth is loosened a little, in addition, the precision cannot be achieved in installation on a construction site, and most of the installed pipe is leaked. (2) The installation process of the heat shrinkable sleeve needs to be baked by fire, so that the heat shrinkable sleeve is not safe, has technical difficulty and operation difficulty, is easy to be heated unevenly and not firmly attached, and has the defects of high water discharge or rupture when the ground surface is settled because only one thin layer is arranged. (3) The stainless steel clamping turn connection is unreliable, and water leakage is very serious. (4) the hot-melt joint is connected, namely the joint and the pipe body are connected for the second time, so that the connection is not firm, and even if the joint and the pipe body are protected by a heat shrinkable sleeve, the problems of falling, cracking and the like exist; therefore, when the inspection well is specifically installed and connected, the extension mode of the second pipe body adopts the PE hollow bidirectional socket joint connector 500 for connection, a sealing ring 600 is further arranged between the connector and the second pipe body 200, the sealing ring 600 is further provided with anti-disengagement teeth, the sealing performance is improved, the PE double-layer bidirectional socket air pressure type elastic sealing connection belongs to a flexible connection mode, in addition, when the outer wall of the connector deforms under pressure, the hollow part of the connector generates reverse air pressure to act on the inner wall of the connector, the inner wall is enabled to be more tightly attached to the pipe and the sealing ring, and the sealing effect is better. Meanwhile, the connecting extensibility is good, and the sealing performance is good under the conditions of earthquake resistance, ground settlement, expansion with heat and contraction with cold and the like. The PE hollow bidirectional socket joint 500 is flexibly connected with the L-shaped multi-peak sealing ring 600, so that the characteristics of sealing performance and flexibility can be fully exerted, and the PE hollow bidirectional socket joint is suitable for geological changes. In the area with unstable geology, the connection mode has strong shock resistance by buried laying under the action of frequent heavy load. The connection mode is really convenient and fast to construct, and when underground water is in existence and difficult to drain, areas easy to collapse and long-term excavation can affect the safety of traffic, buildings and personnel, the PE hollow bidirectional socket joint 500 is adopted for connection, so that the purposes of excavating, coating pipes and backfilling can be achieved.

The above additional technical features can be freely combined and used in superposition by those skilled in the art without conflict.
