Description

Technical Field

[0001] The utility model relates to the technical field of valve wells, in particular to a high-strength composite valve well. Background Art

[0002] The valve well is a valve for underground pipelines and underground pipes (such as tap water, oil, natural gas pipelines, etc.). In order to facilitate the opening and closing of part of the pipe network operation or maintenance work, a pit (or well) similar to a small room is set up, and the valves are installed and arranged in this pit, which is convenient for regular inspection, cleaning and dredging of pipelines to prevent pipeline blockage. This pit is called a valve well. The traditional valve well is a brick structure with slow construction speed, low strength and easy damage. It is gradually being replaced by steel valve wells. The steel valve well is easy to connect and has good sealing, which effectively prevents sewage leakage and is safe and environmentally friendly. However, after the advent of the steel valve well, after practical observations in recent years, it has been found that its performance still has certain shortcomings, because the valve well is generally buried underground and is usually arranged along municipal roads or factory roads. The side of the road is subjected to external forces such as vehicle rolling, and the problem of deformation and damage of the valve well is also more prominent.

[0003] After searching, we found that in the published patent (a new type of high-strength valve well CN214530784U), a reinforcing mechanism is arranged inside the upper well body. The reinforcing mechanism is placed in a triangular shape on the inner wall of the upper well body for support, which blocks the interior of the upper well body, limits the internal space of the upper well body, and restricts the activities of the staff in the upper well body, making it inconvenient for the staff to perform maintenance operations in the well. Therefore, we have launched a new high-strength composite valve well. Utility Model Content

[0004] The main purpose of the utility model is to provide a high-strength composite valve well, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A high-strength composite valve well, comprising a well body, a pipe being interspersed and connected to the lower part of the outer surface of the well body, a No. 1 reinforcement ring being fixedly connected to the upper wall of the well body, a plurality of connecting strips being fixedly connected to the lower end of the No. 1 reinforcement ring, a No. 2 reinforcement ring being fixedly connected to the lower end of the plurality of connecting strips, a No. 2 reinforcement ring being fixedly connected to the lower ends of the plurality of connecting strips, four extension strips being fixedly connected to the outer surface of the No. 1 reinforcement ring, anti-pullout nails being interspersed and connected to the upper ends of the four extension strips, a well cover being provided at the upper end of the well body, a sealing plug being fixedly connected to the lower end of the well cover, a vent being provided at the middle part of the upper end of the well cover, and handles being fixedly connected to the upper left and upper right parts of the well cover.

[0007] Preferably, the No. 1 reinforcement ring and the No. 2 reinforcement ring are both made of alloy structural steel, and the No. 1 reinforcement ring and the No. 2 reinforcement ring are the same in size.

[0008] Preferably, the four connecting strips are distributed in a circular array, and the outer surface of the second reinforcing ring is fixedly connected to the lower wall of the well body.

[0009] Preferably, the four extension strips are all interlaced and connected with the well body, and the four anti-pullout nails are distributed in a ring array.

[0010] Preferably, the outer surface of the sealing plug fits tightly against the inner wall of the well body, and the lower end of the well cover fits tightly against the upper end of the well body.

[0011] Preferably, the vent is communicated with the interior of the well body.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting No. 1 and No. 2 reinforcing rings inside the well body, both of which are made of alloy structural steel, the inner wall of the well body can be supported. By inserting four anti-pullout nails deep into the soil outside the well body, the outside can be anchored, which can improve the overall support strength. Both No. 1 and No. 2 reinforcing rings are attached to the inside of the well body in a circular shape to avoid blocking the internal space of the well body, which is convenient for workers to carry out maintenance operations in the well;

[0014] 2. By setting a sealing plug at the lower end of the manhole cover, the outer surface of the sealing plug fits tightly against the inner wall of the well body, which can prevent external debris, such as stones, branches, etc. from entering the well body, keep the inside of the well body clean, and allow air to circulate inside the well body through the vent.
