[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0023] like Figures 1 to 5 As shown, the prefabricated composite material inspection well includes an upper well body 2 and a lower well body 1. The upper well body 2 has a water inlet hole 4 and several water outlet holes 7 on its side wall. A second sealing ring 8 and a first sealing ring 5 are installed in each water outlet hole 7 and water inlet hole 4, respectively. A water inlet pipe 6 and a water outlet pipe 9 are installed in the first sealing ring 5 and the second sealing ring 8, respectively. The upper well body 2 is installed on the lower well body 1. A well cover 3 is installed on the upper well body 2. A slot 10 is opened on the well cover 3. A sealing rubber ring 11 is installed in the slot 10. The sealing rubber ring 11 is installed between the upper well body 2 and the well cover 3. In this setup, the inlet hole 4 and outlet hole 7 on the side wall of the upper well body 2 are channels for pipe access, used to connect the inlet pipe 6 and the outlet pipe 9 to realize the introduction and distribution of water flow. The first sealing ring 5 and the second sealing ring 8 are respectively installed in the inlet hole 4 and the outlet hole 7, and are tightly fitted with the inlet pipe 6 and the outlet pipe 9 to prevent water leakage at the connection. The lower well body 1 is used to support the upper well body 2 and the internal equipment. The upper well body 2 and the lower well body 1 together form the main space of the inspection well. The well cover 3 is installed on the top of the upper well body 2 to seal the well opening, prevent debris from falling in and pedestrians from falling in. The slot 10 on the well cover 3 is used to fix the sealing ring 11. The sealing ring 11 is installed between the upper well body 2 and the well cover 3 to effectively prevent rainwater and debris from entering the well and improve the sealing performance of the well body.

[0024] like Figures 1 to 5 As shown in the specific embodiment, a first flange 12 and a second flange 13 are respectively provided on the upper well body 2 and the lower well body 1. The first flange 12 and the second flange 13 are respectively provided with a positioning groove 14 and a positioning protrusion 15, and both the first flange 12 and the second flange 13 are provided with connecting holes 16. In this configuration, the first flange 12 of the upper well body 2 and the second flange 13 of the lower well body 1 cooperate with each other through the positioning groove 14 and the positioning protrusion 15, enabling positioning during installation and preventing misalignment of the upper and lower well bodies. The connecting holes 16 provided on both are used for bolts to pass through, and by tightening the bolts, the upper well body 2 and the lower well body 1 are firmly connected, forming a stable overall structure and enhancing the connection strength and stability of the well body in complex underground environments.

[0025] like Figures 1 to 5 As shown, a triangular support 20 is further provided between the bottom of the lower well body 1 and the inner wall. In this configuration, the triangular support 20 utilizes the stability principle of a triangle to effectively enhance the load-bearing capacity of the bottom of the lower well body 1, disperse the pressure borne by the bottom of the well body, prevent the lower well body 1 from deforming or being damaged under soil pressure, and ensure the stability of the overall structure of the inspection well.

[0026] like Figures 1 to 5 As shown, furthermore, a third reinforcing rib 19 is vertically arranged on the outer circumferential surface of the outer wall of the lower well body 1, and the third reinforcing rib 19 extends along the height direction of the lower well body 1. A first reinforcing rib 17 is arranged circumferentially on the outer circumferential surface of the outer wall of the lower well body 1. In this arrangement, the first reinforcing rib 17 can enhance the ability of the lower well body 1 to resist the circumferential compression of the surrounding soil and improve the structural strength in the circumferential direction. The third reinforcing rib 19 can improve the compressive strength of the well body under vertical load. The two work together to effectively enhance the overall strength and deformation resistance of the lower well body 1.

[0027] like Figures 1 to 5 As shown, the outer wall of the upper well body 2 is further provided with a second reinforcing rib 18. In this configuration, the second reinforcing rib 18 on the outer wall of the upper well body 2 can improve the structural rigidity of the upper well body 2, ensure the structural reliability of the upper well body 2, and extend its service life.

[0028] like Figures 1 to 5 As shown, furthermore, sealant is filled between the sealing ring 11 and the upper well body 2 and the well cover 3, between the well cover 3 and the upper well body 2, between the first flange 12 and the second flange 13, between the first sealing ring 5 and the water inlet hole 4 and the water inlet pipe 6, and between the second sealing ring 8 and the water outlet hole 7 and the water outlet pipe 9. In this configuration, the sealant can fill the tiny gaps at the joints of the components, further enhancing the sealing effect, forming multiple sealing barriers to prevent water leakage and the entry of external debris, ensuring the normal operation of the equipment inside the inspection well.

[0029] The implementation principle of the prefabricated composite material inspection well in this embodiment is as follows: Stable load-bearing and leak-proof functions are achieved through structural design optimization and sealing reinforcement technology. Simultaneously, construction efficiency is improved by relying on modular assembly technology. The upper well body 2 and the lower well body 1 are connected by the positioning groove 14 and positioning protrusion 15 of the first flange 12 and the second flange 13, and fastened with bolts in the connecting hole 16, forming a rigid connection structure to ensure the well body maintains its integrity under complex underground loads. The triangular support 20 at the bottom of the lower well body 1, the first circumferential reinforcing rib 17 on the outer wall, and the third vertical reinforcing rib 19, together with the second reinforcing rib 18 on the outer wall of the upper well body 2, enhance the structural strength of the well body from three dimensions: bottom support, circumferential compressive strength, and vertical deformation resistance, resisting soil lateral pressure and heavy ground loads. The water inlet 4 and the water outlet 7 are interference-fitted with the water inlet pipe 6 and the water outlet pipe 9 through the first sealing ring 5 and the second sealing ring 8, and the gaps are filled with sealant to block water seepage. Leakage path, the sealing ring 11 in the slot 10 of the manhole cover 3 and the upper manhole body 2 prevent rainwater and debris from entering. The sealant at the connection of the first flange 12 and the second flange 13 further eliminates the connection gap and enhances the sealing performance of the manhole body underground. During construction, the foundation pit is first excavated and a bedding layer is laid according to the specifications to provide a stable foundation for the manhole body. After the lower manhole body 1 is gently positioned, holes are precisely drilled on the side wall of the lower manhole body 1 according to the design requirements using a special hole opener. The first sealing ring 5 and the second sealing ring 8, as well as the water inlet pipe 6 and the water outlet pipe 9 are installed and sealed. The water meter and water distributor are installed as required. The upper manhole body 2 is quickly connected to the lower manhole body 1 through the positioning groove 14 and positioning protrusion 15 of the first flange 12 and the second flange 13. The bolts are passed through the connection hole 16 and tightened diagonally to achieve a stable connection. The manhole cover 3 and the sealing ring 11 are installed on the upper manhole body 2 to prevent construction debris from falling in. Finally, fine soil is backfilled and compacted in layers, and concrete is poured for fixation.
