AI Technical Summary
In existing technologies, the connection between prefabricated manholes and pipelines is not tight enough, which can lead to quality problems such as water leakage at the joints.
An overflow port is set at the top of the pipe interface and a grouting port is set at the bottom. Grout is injected through the grouting port until it overflows from the overflow port, and then the injection and overflow ports are sealed with sealing strips and removable sealing caps.
This improved the connection quality between the pipe and the well, increased the density of the grouting, and prevented leakage.

[0020] As Figures 1-11 shown, a pipe well structure for grouting connection with a pipe, comprising: a pipe well body 1; a pipe 3; a pipe interface 2 for connecting the pipe 3, at least one pipe interface 2 is fixed on the outer wall of the pipe well body 1 and extends to the outside, the pipe interface 2 is in the shape of a pipe and is connected with the inside of the pipe well body 1, the inner diameter of the pipe interface 2 is greater than the outer diameter of the pipe 3, and a grouting space is formed between the inner diameter of the pipe interface 2 and the outer diameter of the pipe 3; an overflow port 4 opened on the top pipe wall of the pipe interface 2, a grouting port 5 opened on the bottom pipe wall of the pipe interface 2, the overflow port 4 and the grouting port 5 are both connected with the grouting space; a sealing strip 6, the sealing strip 6 is blocked on both sides of the grouting space to ensure that the mortar pouring space is only connected with the outside through the grouting port 5 and the overflow port 4.
[0021] Preferably, in the embodiment, the pipe interface 2 has two, and the two pipe interfaces 2 are symmetrically opened on both sides of the pipe well body 1 in the direction perpendicular to the pipe well body 1.
[0022] Preferably, in the embodiment, the grouting material 7 adopts micro-expansion grouting material.
[0023] AsFigure 7 、 Figure 11 As shown in the drawings, the grouting port 5 and the overflow port 4 are provided with detachable sealing covers 8.
[0024] Preferably, in the embodiment, the pipe well body 1 and the pipe interface 2 are both made of concrete.
[0025] In the construction of the embodiment, as shown in the drawings, the construction includes the following steps: Figures 8-11
[0026] Firstly, the pipe 3 is sleeved into the pipe interface 2, and the annular grouting space is formed between the pipe 3 and the pipe interface 2.
[0027] Secondly, the sealing strips 6 are arranged on the two side edges of the grouting space to seal the two sides of the grouting space.
[0028] Thirdly, the grout 7 is injected into the grouting space through the bottom grouting port 5, and the grouting space is filled with the grout 7 until the grout 7 overflows from the top overflow port 4.
[0029] Fourthly, the sealing covers 8 are covered on the grouting port 5 and the overflow port 4 to prevent the grout 7 in the grouting space from flowing out, and the connection between the pipe 3 and the pipe well 1 is completed.
