Example (b): an anti-seepage reinforcing structure of a pre-buried pipe refers to a figure 1 and comprises a concrete base layer 1 arranged in a pool body 14 (not shown in the figure), a pipeline 2 is pre-buried in the concrete base layer 1, a ring beam 4 is laid in the pool body 14 along the outer periphery of the pipeline 2, the ring beam 4 is formed by laying steel bars and concrete, and the ring beam 4 and the concrete base layer 1 are anchored together through an implanted bolt type anchor bar 5 between the ring beam 4 and the concrete base layer 1. And a water-swelling water stop strip 6 is arranged between the splicing part of the outer wall of the pipeline 2 and the ring beam 4 and the splicing part of the ring beam 4 and the concrete base layer 1 in advance. The arrangement of the ring beam 4 plays a role in reinforcing the space between the concrete base layer 1 and the pipeline 2, and reduces the possibility of deformation, cracks and water seepage between the concrete base layer 1 and the pipeline 2.
Referring to fig. 1, when water seepage occurs at the joint of the outer wall of the pipeline 2 and the ring beam 4 and the joint of the ring beam 4 and the concrete base layer 1, the water seepage port is blocked by the water-swelling water stop 6 due to rainwater swelling, and the effect of further water seepage is achieved. After the operator fixedly connects the ring beam 4 and the pipeline 2 with the concrete, the operator blocks the port of the splicing part formed by the end of the ring beam 4 departing from the concrete base layer 1 and the outer periphery of the pipeline 2 with the concrete, and a concrete filling layer 11 is formed after the concrete is solidified. So arranged, the likelihood of water penetrating from the end ports of the splice between the ring beam 4 and the pipe 2 is reduced.
Referring to fig. 1, grouting pipes 7 for injecting cement are embedded in the concrete base layer 1, and in the present embodiment, four grouting pipes 7 are provided, and the four grouting pipes 7 are provided on the outer periphery of the pipeline 2. The outer wall of the tank body 14 is provided with a through hole (not limited in the figure) communicated with the grouting opening 8 of the grouting pipe 7, and the grout outlet 9 of the grouting pipe 7 extends between the pipeline 2 and the concrete base layer 1. When the operator fixedly connects the ring beam 4 and the pipeline 2 together, the operator injects cement into the grouting pipe 7 from the through hole, the cement is solidified between the concrete base layer 1 and the outer wall of the pipeline 2 to form a cement layer 3, and after grouting is finished, the operator plugs the grouting opening 8 through the closing plate 10. The cement is made of pozzolanic portland cement, and the pozzolanic portland cement has high impermeability and water resistance and can play a role in seepage prevention.
Referring to fig. 1, a cross-shaped support rod 12 is arranged between the outer wall of the pipeline 2 and the concrete base layer 1, in this embodiment, the support rod 12 is arranged between the outer wall of the pipeline 2 and the concrete base layer 1, the support rod 12 is made of a reinforced concrete column, the support rods 12 are arranged at intervals, and two ends of the support rod 12 in the vertical direction are respectively inconsistent with the outer wall of the pipeline 2 and the concrete base layer 1.
