[0002] With the increasing number of urban road construction projects, the water supply and drainage projects in municipal construction are also increasing. Inspection wells are an essential key component in water supply and drainage networks. Traditional inspection wells include concrete inspection wells, traditional plastic inspection wells, etc., but the drawback is that concrete construction has a long construction period.
[0003] The existing technology CN215630516U discloses a manhole, which consists of a manhole base, connecting pipes, and a manhole casing. It enables mass production of components. During construction and installation, according to the design drawings, openings are provided at the joints between the connecting pipes and the manhole base or the manhole casing. The connecting pipes are then fixedly connected to the openings around the manhole base or the manhole casing. Construction is quick, the quality is stable, and the design, manufacturing, and installation time of the manhole is saved.
[0004] However, with the above method, since the size of the well casing is fixed, in the actual installation process, after the well casing is installed in the pit, the height may be too low or too high, which cannot meet the requirements of different pit depths and has a limited scope of application.

[0011] The connector further includes a soil drill bit; the soil drill bit is fixedly connected to the positioning post and is located on the side of the positioning post.
[0012] This utility model discloses a modular inspection well for road construction. During installation, the connecting pipe is first welded to the well base, and then the side of the cylinder with the receiving ring is welded to the well base. The required height of the inspection well is then determined based on the depth of the pit. Multiple well cylinder assemblies are assembled together to adjust the overall height of the inspection well. The assembly process of the well cylinder assembly is as follows: First, one well cylinder assembly is taken, and the end with the receiving ring on the cylinder is inserted into the outer sleeve of another cylinder. A screw is then inserted into the mounting hole on the receiving ring, bringing the two cylinders together end-to-end.

When installing the inspection well, first weld the connecting pipe fitting 102 to the well base 101, then weld the side of the cylinder 103 with the receiving ring 104 to the well base 101. Then, based on the depth of the pit, determine the required height of the inspection well, and adjust the overall height of the inspection well by assembling multiple well cylinder assemblies together. The assembly process of the well cylinder assembly is as follows: first, take one well cylinder assembly, insert one end of the cylinder 103 with the receiving ring 104 into the outer sleeve 105 on another cylinder 103, and then tighten the screw... The rod 106 is inserted into the mounting hole 108 on the receiving ring 104, so that the two cylinders 103 are pressed together end to end. Then, the nut 107 is tightened on the screw 106, thereby connecting the receiving ring 104 to the outer sleeve 105, so that the two well cylinder assemblies are connected together. Then, the assembled inspection well is placed in the well pit, and the water supply pipe in the well pit is connected to the connecting pipe fitting 102. By assembling multiple well cylinder assemblies together, the inspection well can be installed in well pits of different depths, which can meet the requirements of different well pit depths and improve the applicability.
[0023] The two positioning components 109 are mirror-mounted on both sides of the cylinder 103. The two positioning components 109 enable the cylinder 103 to remain stable in the pit.
