Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to the field of drainage of foundation pit water collection wells. Background Art

[0002] Pumping and drainage of foundation pits is an indispensable process in the excavation process, which requires dedicated personnel to monitor and control. In addition, the pumping and drainage situation must be observed frequently during the process to prevent the pumping equipment from being blocked and affecting the pumping efficiency and causing damage to the pumping equipment, so as to avoid water overflow from the collection well and affect the safety and civilized construction of the foundation pit.

[0003] To prevent the pumping equipment from being blocked, some pumping equipment currently installs a filter at the mouth of its pumping pipe. Although this can protect the pumping equipment, since the mouth of the pumping pipe is small, debris accumulated at the mouth will also affect the pumping efficiency. It is still necessary to stop work frequently to clean the mouth of the pumping pipe and replace the filter, which will affect construction efficiency and increase construction costs.

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0022] Reference Figure 1A preferred embodiment of the utility model is a foundation pit water collection well auxiliary pumping and drainage device, comprising: a hanging beam 10, which is erected on the foundation pit water collection well; a hanging cage 20, on which a hanging member 30 is provided, and the hanging cage 20 is hung on the hanging beam 10 through the hanging member 30; the hanging cage 20 has a accommodating space for accommodating a pumping device, and the upper part of the hanging cage 20 is provided with a through port 21 for the pumping equipment to enter and exit, and the lower side wall and / or the bottom of the hanging cage 20 is provided with a filter screen 22, and the accommodating space is connected with the outside through the mesh of the filter screen 22. When the auxiliary pumping and drainage device for the foundation pit water collection well is used, the pumping equipment can be directly placed in the cage 20. Through the hanging beams 10 and the hanging beams 10, the cage 20 can be placed in the foundation pit water collection well so that the lower part of the cage 20 is immersed in water. The water in the foundation pit water collection well can enter the cage 20 through the filter net 22, and the pumping equipment can perform pumping and drainage operations. During the operation, foreign debris can be blocked by the filter net 22 and will not enter the cage 20, so that the pumping equipment is not easy to be blocked. Moreover, the cage 20 can adopt a larger size of filter net 22, which is not easy to be blocked by the accumulation of foreign debris. The structure is simple and practical, which can effectively protect the pumping equipment and can be easily applied to various types of pumping equipment. It is not easy to malfunction and blockage, which helps to improve construction efficiency and reduce construction costs.

[0024] In this embodiment, the bottom and lower side walls of the suspension beam 10 are provided with filter screens 22, which can increase the water inlet surface, improve the drainage efficiency, and be less likely to be completely blocked to affect the drainage, making it more reliable.

[0025] In this embodiment, the cage 20 is connected to the hanging member 30 by a connecting rod 40, which can increase the distance between the cage 20 and the hanging member 30, and then increase the lowering depth of the cage 20. It can be suitable for deeper foundation pit sump and is also convenient for the erection of the hanging beam 10.

[0026] In this embodiment, the connecting rod 40 is a telescopic rod, and a locking structure for locking the telescopic action thereof is provided on the connecting rod 40, so that the distance between the cage 20 and the hanging member 30 can be adjusted as needed to adapt to the operation needs of foundation pit sump with different depths, and the use is more flexible and convenient. The telescopic rod is widely used and has a variety of common structures. The locking structure can adopt common structures such as a latch structure, a rack tooth wedge structure, and a clamping screw. Those skilled in the art can flexibly select them according to their needs, and no further details are given here.

[0027] In this embodiment, the hanging member 30 is a hanging ring, and the hanging beam 10 is inserted into the hanging ring, and the hanging ring can slide along the hanging beam 10. This can prevent the hanging member 30 from being loosened from the hanging beam 10 during operation, reduce the failure rate, and be safer and more reliable. On the other hand, the lateral position of the cage 20 can be adjusted by sliding the hanging ring along the hanging beam 10, which is more flexible and convenient to use. In other embodiments, the hanging member 30 can also adopt other common hanging structures such as rope loops and hooks as needed, and is not limited to this.

[0028] In this embodiment, there are two hanging beams 10, and each hanging beam 10 corresponds to at least two hanging members 30, which helps to ensure the stability of the cage 20 and improve the load-bearing capacity of the cage 20, and has a wider range of applications and is safer and more reliable. In this embodiment, there are four hanging members 30, and each hanging beam 10 corresponds to two hanging members 30. In other embodiments, the number and corresponding relationship of the hanging beams 10 and the hanging members 30 can be flexibly adjusted as needed, and are not limited thereto.

[0029] In this embodiment, the cage 20 is provided with an openable cage door (not shown in the figure), which is used to close the through opening 21, so as to prevent foreign debris from entering the cage 20 through the through opening 21 during operation and affecting the operation of the pumping device, which is safer and more reliable. The cage door can be opened and closed by common methods such as hinges and pull-out guide rails, and those skilled in the art can flexibly select them.

[0030] In this embodiment, the frame of the cage 20 is welded by multiple angle steels and is in the shape of a cuboid. A wire mesh is provided on the frame as a filter 22. The shape is regular and the required materials are also easily available at the construction site, which is convenient for processing and manufacturing. In other embodiments, the cage 20 can also select other suitable shapes and structures as needed, and is not limited thereto.

[0031] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0032] The above description is only a preferred implementation mode of the present utility model. Any technical solution that achieves the purpose of the present utility model by basically the same means belongs to the protection scope of the present utility model.
