[0017] The following is a further detailed description through specific implementation methods:

[0018] like Figures 1 to 4 As shown:

[0019] A municipal drainage well includes a regulating module and a plurality of fixing modules. The fixing modules are installed on the outer side wall of the regulating module. Each fixing module is evenly installed on the outer side of a drainage cylinder 1. The fixing modules are used to fix the regulating module in the road surface.

[0020] The adjustment module includes a drainage cylinder 1, a lifting cylinder 3 and a manhole cover 8. The inner side of the drainage cylinder 1 is provided with an internal thread 2, and the outer wall of the lifting cylinder 3 is provided with an external thread 4 that matches the internal thread 2, so that the lifting cylinder 3 can be screwed into the drainage cylinder 1 through the thread. After the drainage cylinder 1 is fixed, the lifting cylinder 3 is rotated to change the height position of the lifting cylinder 3. A support ring plate 5 is fixedly installed on the inner side of the top of the lifting cylinder 3. The manhole cover 8 is installed on the top of the support ring plate 5 and the lifting cylinder 3, and the manhole cover 8 is slightly raised at the top of the lifting cylinder 3, so that when the manhole cover 8 is flush with the road surface, the lifting cylinder 3 does not protrude from the road surface;

[0021] The fixing module includes a fixing ring plate 9 and an outer sleeve 10. The fixing ring plate 9 is fixedly installed on the outside of the drainage tube 1. At the same time, the outer sleeve 10 is fixedly installed on the fixing ring plate 9 and is separated from the drainage pipe, so that there is a certain gap between the drainage pipe and the outer sleeve. A number of pouring holes 13 are evenly opened on the outer wall of the outer sleeve, so that when the device is cast together with the pavement, concrete can enter into the gap between the outer sleeve and the drainage pipe through the pouring holes 13, and finally the pavement and the fixing module are interlocked with each other.

[0022] A plurality of slots 6 are evenly formed on the support ring plate 5 , which facilitate the accumulated water to pass through the slots 6 from the manhole cover 8 into the drain pipe. At the same time, the user can use a tool to engage with the slots 6 and then twist the lifting cylinder 3 .

[0023] A plurality of ribs 11 are provided between the fixed ring plate 9 and the outer sleeve 10 , and the ribs 11 are used to enhance the connection strength between the fixed ring plate 9 and the outer sleeve.

[0024] The manhole cover 8 and the lifting cylinder 3 are connected by a connecting rope 7 to prevent the manhole cover 8 from being completely separated from the lifting cylinder 3, thereby preventing theft to a certain extent.

[0025] A plurality of casting grooves 14 are provided on the fixed ring plate 9 , and the casting grooves 14 make the connection strength between the fixed ring plate 9 and the concrete pavement more stronger.

[0026] The specific implementation process is as follows:

[0027] When using this municipal drainage well, cast the drainage well and the concrete pavement as one, so that the concrete filler 12 enters the casting groove 14 of the fixed ring plate 9, and at the same time, the concrete filler 12 passes through the casting hole 13 at the outer sleeve and enters the space between the outer sleeve and the drainage barrel 1, so that the device and the road surface are interlocked and fixed together; if the drainage well sinks due to reasons such as a large number of vehicles passing through this municipal drainage well or the drainage well has been used for a long time, the user can lift the manhole cover 8 to expose the support ring plate 5, and use a tool to clamp it into the card groove 6 at the support ring plate 5, rotate the support ring plate 5, and the support ring plate 5 drives the lifting barrel 3 to rotate together, and the lifting barrel 3 can change its high position until the manhole cover 8 is reinstalled at the lifting barrel 3 and the support ring plate 5, and the top surface of the manhole cover 8 is flush with the concrete pavement.

[0028] This municipal drainage well adjusts the position of the lifting cylinder 3 at the drainage cylinder 1, and then adjusts the height position of the manhole cover 8 installed on the top of the lifting cylinder 3. After the drainage well sinks, the manhole cover 8 is adjusted to the same height as the ground to avoid the drainage well position on the road surface and improve the safety performance of the road surface. At the same time, by embedding the fixed module into the road, the fixed module and the road are embedded with each other, further reducing the risk of the drainage well sinking.
