Detailed Description
The present invention is described in further detail below with reference to the data in conjunction with the accompanying drawings. It should be understood that the embodiments are only intended to illustrate the invention and do not limit the scope of the invention in any way.
As shown in fig. 1-2, the restoration structure for the sewage inspection well of the present application includes a leading-in steel pipe 12, a diversion steel cylinder 11 and a leading-out steel pipe 13 which are sequentially communicated along a water flow direction; one end of the introduction steel pipe 12 is connected to the upstream branch pipe 21; one end of the lead-out steel pipe 13 is connected to the downstream branch pipe 22; the diversion steel cylinder 11 is arranged in the sewage inspection well 2 in the center, and the minimum distance between the outer side wall of the diversion steel cylinder 11 and the inner side wall of the sewage inspection well 2 is larger than 1.2M. Therefore, the repair structure can bear and buffer the water flowing capacity of the original sewage inspection well, and meanwhile, an annular dry bin operation area 23 is formed in the original sewage inspection well, the dry bin operation area 23 enables workers to enter the sewage inspection well 2 during the water flowing period of the pipeline, so that the repair construction can be carried out on the inner side of the sewage inspection well 2 during the period that the original pipeline does not stop water.
In this embodiment, the annular gap between the steel pipe and the upstream branch pipe is filled with the soil cement 31, and then sealed with the epoxy resin 32. The annular gap between the outgoing steel pipe and the downstream branch pipe is filled with the plain cement soil 31, and then sealed by the epoxy resin 32. The sealing structure is quick in construction, and subsequent disassembling operation is easier.
In this embodiment, the diversion steel cylinder is integrally formed, and the sidewall of the diversion steel cylinder is provided with a connection hole 113 in advance, the connection hole 113 is used for connecting the other ends of the leading-in steel pipe and the leading-out steel pipe, and the connection hole 113 is coaxial with the corresponding branch pipe. The diversion steel cylinder is integrally formed, and the connecting hole 113 coaxial with the branch pipe is preset, so that the repairing structure can be rapidly deployed and rapidly detached. The bottom surface of the guide steel cylinder is provided with a reinforcing rib 111 extending along the width direction. The bottom corner of the diversion steel cylinder is provided with a reinforcing rib 112. Thereby making the integrally formed guide steel cylinder not easy to deform in the integral hoisting process.
In one embodiment, the height of the diversion steel cylinder is the same as that of the sewage inspection well, so that the diversion steel cylinder is convenient to connect with branch pipes with different heights while the maximum buffer capacity is ensured.
In another embodiment as shown in fig. 3, an adjacent drainage system 4 is connected above the diversion steel cylinder to further increase the drainage capacity of the restoration structure. Preferably, the length and width of the diversion steel cylinder are more than 6M 4M. Thereby facilitating the placement of the adjacent pump and the adjacent discharge pipe.
In the embodiment, the heights of the upstream branch pipe and the downstream branch pipe are the same, the guide steel cylinder is divided into a top part 114 and a bottom part 115 which are detachable from top to bottom, and the bottom elevation of the top part 114 is flush with the top elevation of the branch pipe. Thereby further facilitating the rapid installation of the leading-in steel pipe and the leading-out steel pipe and the deployment and the disassembly of the diversion steel cylinder.
