Description

Technical Field

[0001] The utility model relates to the technical field of valve well installation, in particular to a valve well installation structure. Background Art

[0002] The valve well is a pit (or well) similar to a small room, where valves are installed and arranged in underground pipelines and underground pipes (such as water, oil, and natural gas pipelines) to facilitate opening and closing of part of the pipe network or maintenance work. This pit is called a valve well.

[0003] Chinese patent CN215442023U discloses an underground valve well to solve the problem that the original underground valve well does not use a double-fixed clip water pipe structure and a structure that is slidably installed inside the supporting wellbore, which not only reduces the overall durability of the wellbore, but also reduces the practicality and durability of the underground valve well. It includes a wellbore, which is a hollow cylindrical structure, a well cover, which is a conical structure, and the well cover is centrally installed at the upper end of the wellbore; a fixed disk, which is installed at the central lower end of the well cover, and the fixed disk is installed on the hollow inner side of the wellbore; a push block, which is a semi-cylindrical structure, and the push blocks are arranged in a ring at the lower end of the fixed disk. In the utility model, the baffle plate can cooperate with the fixed disk to temporarily store the accumulated water on the inner side of the wellbore, and at the same time, when the fixed disk is taken out, the baffle plate can perform a self-external structural flip to allow the accumulated water in the fixed disk to flow out.

[0004] However, the above technical solution still has the following defects: the space in the well is reduced to reduce the method of water intrusion, which is not conducive to the installation of valves in the well and is not conducive to manual underground work. Utility Model Content

[0007] A valve well installation structure comprises a well body and a well cover, wherein a sump is provided at the bottom of the well body, and a water treatment component is connected to the sump; the well body comprises a bottom plate, a well wall and a cover plate, a prefabricated wellbore is installed on the cover plate, the well cover is installed on the prefabricated wellbore, and a pier is provided in the well body; the water treatment component comprises a detachable filter basket installed in the sump, the bottom of the filter basket is suspended above the bottom of the sump, the water treatment component also comprises a pumping pipe, the water inlet end of the pumping pipe is located at the bottom of the sump, the pumping pipe is in contact with the well wall and the prefabricated wellbore and extends out of the well, the water outlet end of the pumping pipe is detachably connected to an external pumping pump, and the water outlet end of the pumping pipe is provided with a stop valve.

[0008] Furthermore, the sump is an inverted cone structure, and the shape of the filter basket fits the inner wall design of the sump.

[0009] Furthermore, a filter head is connected to the water inlet end of the water pumping pipe, and a replaceable filter element is provided inside the filter head.

[0010] Furthermore, the well wall adopts a brick structure, and a through hole for pipe installation is opened on the well wall.

[0011] Furthermore, steps are provided in the prefabricated wellbore for 360° rotation, and a hook is provided at the wellhead of the prefabricated wellbore, on which a high-strength protective net is detachably mounted.

[0012] Beneficial effects of the utility model:

[0013] In actual use scenarios, the size of the well body is set to a corresponding size according to the number of valves that need to be installed. The cover plate is made of reinforced concrete structure. A prefabricated wellbore is installed at a suitable position on the cover plate as a manhole and an operation hole. The valve is installed according to the national standard and supported by piers. A filter basket is designed in the sump to intercept large volumes of garbage or large-size mud and sand. The accumulated water flows into the bottom of the sump after preliminary filtration, and then an external pump is connected to pump out the accumulated water using a pumping pipe. This structure does not require manual entry into the well to complete the cleaning of the accumulated water, which is more convenient. The well environment of the utility model is simple, the valve pipeline is easy to install, and it is also easy to clean the accumulated water. BRIEF DESCRIPTION OF THE DRAWINGS
