Technical Field

[0001] The utility model relates to a manhole cover, in particular to an integrated manhole cover used in the building foundation construction industry. Background Art

[0002] Currently, before pile foundation construction begins, the water in the well needs to be pumped out using a water pump. Furthermore, when working in wet soil, vacuum pumps must be replaced, requiring constant switching between different devices, hindering construction efficiency. Summary of the Invention

[0011] The utility model integrates the water pumping pipe and the vacuum pumping pipe on a manhole cover, and realizes one-way conduction through the connecting pipe and the one-way valve. Therefore, water pumping and vacuum pumping can be completed with one set of devices during the entire construction process without the need for equipment switching, which greatly improves construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a structural schematic diagram of an integrated manhole cover of the present utility model.

[0013] in:

[0014] Manhole cover body 1, ring 2, handle 3, water suction pipe 4, vacuum pipe 5, tee 6, elbow 7, connecting pipe 8, one-way valve 9, threading pipe 10. DETAILED DESCRIPTION

[0015] See also Figure 1 The utility model relates to an integrated manhole cover, which includes a manhole cover body 1. A ring 2 with an annular structure is welded to the outer edge of the bottom of the manhole cover body 1, so that when the manhole cover body 1 is installed on the well pipe, the inner side of the ring 2 can be in close contact with the outer wall of the well pipe to ensure the sealing performance.

[0016] At the same time, a handle 3 is vertically connected to the middle of the manhole cover body 1, so as to facilitate the use of the integrated manhole cover of the utility model. A water suction pipe 4 is connected to the manhole cover body 1. The top of the water suction pipe 4 is used to connect to the vacuum pump, and the bottom of the water suction pipe 4 is used to connect to the submersible pump located in the wellbore. A tee piece 6 is connected in series to one end of the water suction pipe 4 located outside the manhole cover body 1.

[0017] A vacuum tube 5 is also connected to the manhole cover body 1, and an elbow 7 is connected to one end of the vacuum tube 5 located outside the manhole cover body 1. The elbow 7 and the lateral through hole of the tee piece 6 are connected by a connecting pipe 8, and a one-way valve 9 is connected in series to the connecting pipe 8.

[0018] Finally, a wire threading tube 10 is also connected to the manhole cover body 1, which is used to insert the power line for powering the submersible motor and the control line, and when the threading is completed, it is wrapped with a stretch film to achieve sealing to prevent air leakage.

[0019] The working principle of this utility model is:

[0020] When the water level in the wellbore is high, the submersible pump operates to draw water through the pumping pipe 4 into the vacuum pump and then discharges it. The water drawn out at this time also cools the vacuum pump. Furthermore, due to the presence of the one-way valve 9, the water does not flow back into the wellbore through the vacuum pipe 5 during this process. When the water in the wellbore is pumped below the working water level and cannot be drawn out, the submersible pump stops working. The vacuum pump continues to operate, drawing air from the well through the vacuum pipe 5 and the one-way valve 9, thereby creating a negative pressure environment in the well pipe. This causes water in the surrounding soil layer to precipitate into the well pipe. When the water level reaches a certain level, the submersible pump starts again to draw water from the well pipe. At this time, the water is again drawn out through the vacuum pump and cools the vacuum pump. This cycle repeats until the operation is completed. Although the vacuum pump is in operation throughout the entire process, it is intermittently cooled by water, thereby ensuring its operational safety.

[0021] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
