Description

Technical Field

[0001] This application relates to the technical field of construction engineering, and in particular to a temporary water supply and drainage device for construction projects. Background Art

[0002] During the construction process of construction projects, temporary water supply and drainage devices are indispensable and important equipment, mainly used for pumping the accumulated water in the foundation pit to ensure the smooth progress of construction. At present, there are various temporary water supply and drainage devices on the market, but most of the devices are prone to clogging problems when dealing with sewage containing a large amount of sediment, which affects the pumping efficiency, and even causes damage to the water pump and shortens its service life.

[0003] In the existing technical solutions, generally, a filter screen is added at the pumping end to reduce the sediment entering the pump body. For example, a foundation pit drainage anti-clogging system with the authorization announcement number CN211285662U reduces the sediment passing through by setting a connection pipe to be quickly disassembled from the box body and the pipe joint, and at the same time setting multiple independently used connection pipes, so that the filter screen connected to the connection pipe can be replaced while the water pump is running, reducing the sediment passing through and facilitating the quick replacement of the filter screen. However, in the actual use process, although a filtering device is used to reduce the sediment entering the pipeline, there will still be a small part of the sediment entering the pipeline and then causing clogging, which affects the operation of the pump body. Summary of the Utility Model

[0004] In order to solve the problem that sediment still passes through the filter screen and enters the pump body, and there is still sediment entering the pipeline causing clogging or damage to the pump body, this application provides a temporary water supply and drainage device for construction projects.

[0005] A temporary water supply and drainage device for construction projects provided by this application adopts the following technical solutions:

[0006] A temporary water supply and drainage device for construction projects includes a pumping pipeline connected to the water inlet end of the temporary drainage device. The end of the pumping pipeline is connected with a filter cover, and an interception component is arranged inside the pumping pipeline;

[0007] The interception component includes a rotating shaft rotatably arranged inside the pumping pipeline, and spiral blades are arranged on the rotating shaft for intercepting and reversely conveying the sediment in the water.

[0008] Preferably, a number of water filtering holes are arranged on the spiral blades, and a driving component is also arranged on the rotating shaft for driving the rotating shaft and the spiral blades to rotate.

[0009] Preferably, the pumping pipeline includes a vertical pipe and a straight pipe. The straight pipe is arranged on the side of the vertical pipe and above the spiral blades.

[0010] Preferably, the filter cover includes a connecting pipe provided at the lower end of the vertical pipe. A support cover is provided at the lower end of the connecting pipe, and a partition is provided inside the support cover.

[0011] Preferably, the support cover includes a filter net provided on the connecting pipe, and a strengthening structure is provided on the side of the filter net to improve the overall support strength.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] Through the combined use of the pumping pipeline, the filter cover, and the interception component, the pumping pipeline is connected to the water pump to pump the water in the foundation pit. The support cover is used to initially intercept the soil and sand, reducing the sediment entering the pumping pipeline. After the water enters the vertical pipe, the spiral blades and the water filtering holes facilitate the flow of water while effectively intercepting and discharging the sediment in the water, preventing pipeline blockage and reducing pump body damage; compared with the prior art, it has the effects of preventing blockage and extending the service life of the pump body.

Detailed Description of the Embodiment

[0018] The following will further describe the present application in detail Figures 1 - 3 with reference to the accompanying drawings.

[0019] The embodiment of the present application discloses a temporary water supply and drainage device for construction engineering construction. Refer to Figures 1 - 3, A temporary water supply and drainage device for construction engineering construction, including a pumping pipeline 1 connected to the water inlet end of the temporary drainage device. A filter cover 2 is connected to the lower end of the pumping pipeline 1. An interception component 3 is installed inside the pumping pipeline 1. The interception component 3 includes a rotating shaft 301 rotatably installed inside the pumping pipeline 1. A spiral blade 302 with water filtering holes is installed on the rotating shaft 301. A driving component is also installed on the rotating shaft 301. The driving component can be selected in the way of electric or fluid drive, such as a turbine 303 installed on the rotating shaft 301. The turbine 303 is located above the spiral blade 302. The water flow passing through the pumping pipeline 1 can be used to drive the turbine 303 to rotate, and then drive the turbine 303 to rotate. Then, the turbine 303 drives the spiral blade 302 to discharge the intercepted sediment downward.

[0020] Refer to Figure 3 , The pumping pipeline 1 includes a straight pipe 103 connected to the water inlet end of the temporary water supply and drainage device through a flange. The end of the straight pipe 103 is connected to a vertical pipe 101. The rotating shaft 301 is rotatably installed on an end cover 102. The straight pipe 103 is located above the turbine 303 to ensure that the water flow can always pass through the turbine 303 and drive the turbine 303 to operate. The top of the vertical pipe 101 is detachably installed with an end cover 102, such as by bolts, and a sealing ring is used for sealing at the connection between the vertical pipe 101 and the end cover 102. The temporary water supply and drainage device can select a suitable water pump according to needs.

[0021] Refer to Figure 2 , The filter cover 2 includes a connecting pipe 201 detachably installed at the lower end of the vertical pipe 101. A support cover 202 is installed at the lower end of the connecting pipe 201. The support cover 202 includes a filter net 2021 installed on the connecting pipe 201. The end of the spiral blade 302 is located inside the filter net 2021. A reinforcing structure is installed on the side of the filter net 2021. The reinforcing structure adopts a support skeleton 2022 composed of several reinforcing ribs to improve the support and anti-deformation ability of the support cover 202. The support cover 202 is designed in a horn shape. By installing a partition 203 inside the support cover 202, the support area is expanded, the support cover 202 is prevented from sinking into the sediment, and at the same time, the sediment can be separated from the internal space of the support cover 202 to prevent the sediment from surging up.

[0022] The implementation principle of a temporary water supply and drainage device for construction engineering construction in an embodiment of this application is as follows:

[0023] First, connect the straight pipe part 103 of the pumping pipeline 1 to the water inlet end of the water pump at the construction site of the construction project through a flange to ensure a tight and leak-free connection. Then, install the connecting pipe 201 of the filter cover 2 at the lower end of the vertical pipe 101 to ensure a tight connection between the two.

[0024] Start the water pump. When the water flow at the construction site passes through the filter screen 2021 to filter out the sand, small stones and mud in the water and enters the pumping pipeline 1 through the temporary drainage device, the water flow first passes through the spiral blade 302. The spiral blade 302 is provided with water filtering holes, allowing water to pass through but intercepting impurities such as sediment. At the same time, the water flow drives the turbine 303 installed above the rotating shaft 301 to rotate, and the turbine 303 drives the rotating shaft 301 and the spiral blade 302 to rotate. The rotation of the spiral blade 302 pushes the intercepted sediment and other impurities downward into 2021.
