[0013] (1) The prefabricated assembled concrete underground equipment well is arranged in a straight line through the auxiliary ladder groove on the first underground equipment cylinder and the auxiliary ladder groove on the second underground equipment cylinder. The on-site pouring personnel form a seal at the joint between the first underground equipment cylinder and the second underground equipment cylinder by pouring sealing materials, and the poured materials can be well guided by the inverted V-shape of the docking branch groove, thereby improving the flow rate efficiency of the liquid sealing at the joint between the first underground equipment cylinder and the second underground equipment cylinder, thereby improving the sealing method of the joint between the traditional flat first underground equipment cylinder and the second underground equipment cylinder after assembly, ensuring the assembly efficiency of the first underground equipment cylinder and the second underground equipment cylinder after assembly, and reducing the cost of manual intervention.

[0025] See also Figure 1-4 The utility model provides a technical solution: a prefabricated assembled concrete underground equipment well, including a first underground equipment tube 1 and a second underground equipment tube 2, the first underground equipment tube 1 is located above the second underground equipment tube 2, and the first underground equipment tube 1 and the second underground equipment tube 2 can be assembled into an underground equipment well through the assembly between the first underground equipment tube 1 and the second underground equipment tube 2.

[0026] Furthermore, an outer branch slot 3 is provided on the surface of the first underground equipment tube 1, and an outer branch slot 3 is also provided on the surface of the second underground equipment tube 2. The outer branch slot 3 forms a depression on the outer sides of the first underground equipment tube 1 and the second underground equipment tube 2, so as to increase the contact area with the outer sides of the first underground equipment tube 1 and the second underground equipment tube 2 when filling sand or earth thereon, thereby improving the pre-buried stability of the first underground equipment tube 1 and the second underground equipment tube 2.

[0027] Furthermore, auxiliary stair grooves 4 are opened on the inner sides of the first underground equipment tube 1 and the second underground equipment tube 2. By opening the auxiliary stair grooves 4 on the inner sides of the first underground equipment tube 1 and the second underground equipment tube 2, when the first underground equipment tube 1 and the second underground equipment tube 2 are assembled and used for the equipment well, the auxiliary stair grooves 4 on the first underground equipment tube 1 can assist personnel in climbing when encountering special circumstances, thereby improving the disadvantage that the traditional smooth surface first underground equipment tube 1 does not have the function of assisting climbing.

[0028] Furthermore, a docking branch groove 5 is provided on the surface of the abutment between the second underground equipment tube 2 and the first underground equipment tube 1, and a first through groove 6 is provided on the inner side of the second underground equipment tube 2. The number of the first through grooves 6 is four groups, and the shape between every two adjacent first through grooves 6 on the second underground equipment tube 2 is an inverted V shape. A docking support ring 7 is bonded and installed on the surface of the abutment between the first underground equipment tube 1 and the second underground equipment tube 2, and a second through groove 8 that is interconnected is provided inside the docking support ring 7 and the first underground equipment tube 1, and the shapes of the docking branch groove 5 and the docking support ring 7 are both truncated cones.

[0029] Specifically, when the equipment well is assembled by the first underground equipment tube 1 and the second underground equipment tube 2, after the second underground equipment tube 2 is installed in the equipment well, the first underground equipment tube 1 is built above the second underground equipment tube 2. At this time, when the first underground equipment tube 1 is abutted against the truncated cone-shaped docking support ring 7 on the second underground equipment tube 2, a more accurate and convenient docking assembly between the first underground equipment tube 1 and the second underground equipment tube 2 can be achieved. When the first underground equipment tube 1 and the second underground equipment tube 2 are assembled, the second through groove 8 on the first underground equipment tube 1 will be misaligned with the first through groove 6 on the second underground equipment tube 2. , and the auxiliary ladder groove 4 on the first underground equipment tube 1 and the auxiliary ladder groove 4 on the second underground equipment tube 2 will be arranged in a line, and the on-site pouring personnel form a seal on the joint of the first underground equipment tube 1 and the second underground equipment tube 2 by pouring sealing materials, and the poured material can be well guided by the inverted V-shape of the docking branch groove 5, thereby improving the flow rate efficiency of the liquid sealing at the joint of the first underground equipment tube 1 and the second underground equipment tube 2, thereby improving the sealing method of the joint of the traditional planar first underground equipment tube 1 and the second underground equipment tube 2 after assembly, ensuring the assembly efficiency of the first underground equipment tube 1 and the second underground equipment tube 2 after assembly, and reducing the cost of manual intervention.

[0030] Furthermore, a first steel bar body 9 and a second steel bar body 10 are cast and installed on the inner side of the first underground equipment tube 1. The first steel bar body 9 and the second steel bar body 10 are arranged in a cross shape in the first underground equipment tube 1. The cross binding between the first steel bar body 9 and the second steel bar body 10 can improve the firmness of the first underground equipment tube 1 after casting.

[0031] Working principle: A prefabricated assembled concrete underground equipment well, when the equipment well is assembled by a first underground equipment tube 1 and a second underground equipment tube 2, after the second underground equipment tube 2 is installed in the equipment well, the first underground equipment tube 1 is built above the second underground equipment tube 2. At this time, the first underground equipment tube 1 is abutted against the truncated cone-shaped docking support ring 7 on the second underground equipment tube 2 by its own truncated cone-shaped docking support groove 5, so that the first underground equipment tube 1 and the second underground equipment tube 2 can be more accurately and conveniently docked and assembled. When the first underground equipment tube 1 and the second underground equipment tube 2 are assembled, the on-site pouring personnel form a seal at the docking point of the first underground equipment tube 1 and the second underground equipment tube 2 by pouring sealing materials.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
