Description

Technical Field

[0001] This invention relates to the field of precipitation engineering technology, and in particular to a simple device for preventing bending and folding of a hose in a subway station's precipitation well. Background Technology

[0002] In the construction of subway stations, in order to ensure that the groundwater level can be effectively controlled throughout the construction process, all subway station construction must take dewatering measures. Most of the dewatering wells are located inside the foundation pit. Water pumps are used in combination with hoses to pump water from inside the dewatering wells to the outside of the foundation pit, thereby achieving the effect of dewatering and draining the foundation pit.

[0003] However, in actual construction, due to the large depth of the station foundation pit, plastic flexible hoses are mostly used for drainage pipes to facilitate installation and dismantling. Chinese patent application CN200920221500.2 discloses a device to prevent bending of the outlet pipe of a dewatering well, consisting of a helical spring and a clamp. Its key feature is that a clamp is horizontally fixed to the lower end of the helical spring. One end of the helical spring is horizontally welded to the outer wall of the clamp, and the helical spring is fixed to the connecting pipe of the main drainage pipe via the clamp. The other end of the helical spring extends beyond the uppermost end of the connecting pipe. The outlet pipe is inserted into the connecting pipe. When water flows through, the outlet pipe will bend due to gravity. When the outlet pipe contacts the helical spring, it will be supported, effectively preventing bending of the outlet pipe, reducing the impact on dewatering, and effectively ensuring construction safety.

[0004] However, when the dewatering hose is laid outward along the height of the pit, it is difficult to control its verticality and curvature. The most common problem is that the hose bends at the wellhead of the dewatering well, with the bend angle reaching up to 90°. Existing technology using helical springs is ineffective, which seriously affects the efficiency of dewatering and the normal operation of the water pump. Summary of the Invention

[0005] In order to overcome the defect of bending at the wellhead of the dewatering well in the prior art, the present invention provides a simple anti-bending device for the dewatering well hose in subway stations, which effectively reduces the risk of pump burnout and pump stoppage caused by bending of the dewatering hose during operation.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a simple anti-bending device for a hose in a subway station dewatering well, comprising an L-shaped channel steel set on the dewatering well, the L-shaped channel steel being equidistantly arranged along the circumference of the dewatering well, a sliding component being set on each L-shaped channel steel, a rotating component being sleeved on each sliding component, and a dewatering hose being set at the center of the rotating component.

[0007] L-shaped channel steel is easy to fix on the dewatering well.

[0008] As a further improvement of the present invention, the L-shaped channel steel includes a horizontal section and a vertical section. The thick part of the horizontal section has an opening along the pipe diameter direction, and the thick part of the vertical section has an arc groove. The opening facilitates the fixing of the sliding component, and the arc groove facilitates a tight fit with the outer wall of the dewatering well.

[0009] As a further improvement of the present invention, the sliding component includes a flat steel bar, one end of which is provided with a bolt, and the other end of which is provided with an arc-shaped groove. The flat steel bar is placed on the horizontal section of the L-shaped channel steel. After the position of the sliding component is adjusted, the bolt is inserted into the opening and tightened, and the sliding component and the L-shaped channel steel are connected as a whole.

[0010] As a further improvement of the present invention, the arc-shaped groove is provided with a slot hole. The arc-shaped groove is used to hold the ball bearing, and the connecting rod slides on the slot hole.

[0011] As a further improvement of the present invention, the rotating assembly includes a connecting rod, one end of which is fixedly connected to an arc-shaped steel bar, and the other end of which is rotatably connected to a ball bearing. This facilitates adjustment of the position of the arc-shaped steel bar.

[0012] As a further improvement of the present invention, a rubber pad is provided on the side of the curved steel. The rubber pad prevents long-term friction damage between the rainwater hose and the curved steel.

[0013] As a further improvement of the present invention, a helical spring is fitted onto the drainage hose, and the upper end of the helical spring is connected to the rotating assembly. The helical spring effectively prevents the drainage hose from bending.

[0014] Compared with the prior art, the present invention has the following advantages: the upper end of the helical spring is connected to the rotating assembly. Utilizing the L-shaped channel steel, sliding assembly, and rotating assembly, the rainwater hose is effectively prevented from bending and fixed to the rainwater well. When the rainwater hose contacts the helical spring, it is supported, and the helical spring effectively prevents the outlet pipe from bending, reducing the impact on the rainwater hose and effectively ensuring construction safety.

[0025] To make the technical solution and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments.

[0026] Reference Figure 1 and Figure 2 This invention discloses a simple anti-bending device for a hose in a subway station dewatering well. It includes L-shaped channel steel 2 installed on a dewatering well 1, with the L-shaped channel steel 2 evenly spaced around the circumference of the well 1. Each L-shaped channel steel 2 has a sliding component 3, and each sliding component 3 is fitted with a rotating component 4. A dewatering hose 5 is installed at the center of the rotating component 4, and a helical spring 6 is fitted onto the dewatering hose 5. The upper end of the helical spring 6 is connected to the rotating component 4. Using the L-shaped channel steel 2, sliding component 3, and rotating component 4, the dewatering hose 5 is effectively prevented from bending and fixed to the dewatering well 1. The helical spring 6 effectively prevents the outlet pipe from bending.

[0027] Reference Figure 3 , Figure 4 and Figure 5 The L-shaped channel steel is easy to fix to the dewatering well 1. The L-shaped channel steel 2 includes a horizontal section 21 and a vertical section 22. The thick part of the horizontal section 21 has an opening 23 along the pipe diameter direction, and the thick part of the vertical section 22 has an arc groove 24. The opening 23 facilitates the fixing of the sliding component 3, and the arc groove 24 facilitates a tight fit with the outer wall of the dewatering well 1.

[0028] Reference Figure 6 and Figure 7The sliding component 3 includes a flat steel bar 31, with a bolt 32 at one end and an arc-shaped groove 33 at the other end. The flat steel bar 31 is placed on the horizontal section 21 of the L-shaped channel steel 2. After adjusting the position of the sliding component 3, the bolt 32 is inserted into the opening 23 and tightened, connecting the sliding component 3 and the L-shaped channel steel 2 into a whole. The arc-shaped groove 33 has a slot 34. The arc-shaped groove 33 is used to hold the ball bearing 43, and the connecting rod 41 slides on the slot 34.

[0029] Reference Figure 8 The rotating assembly 4 includes a connecting rod 41, one end of which is fixedly connected to an arc-shaped steel 42, and the other end of which is rotatably connected to a ball bearing 43. This facilitates adjustment of the position of the arc-shaped steel 42. A rubber pad 44 is provided on the side of the arc-shaped steel 42. The rubber pad 44 prevents long-term friction damage between the rainwater hose and the arc-shaped steel 42.

[0030] The upper end of the helical spring 6 is connected to the rotating assembly 4. Utilizing the L-shaped channel steel 2, the sliding assembly 3, and the rotating assembly 4, the downspout hose 5 is effectively prevented from bending and fixed to the downspout well 1. When the downspout hose 5 contacts the helical spring 6, it is supported, and the helical spring 6 effectively prevents the outlet pipe from bending. The flat steel 31 of the sliding assembly 3 slides within the horizontal section 21 of the L-shaped channel steel 2, adapting to downspout wells 1 and downspout hoses 5 of different diameters. Considering that the downspout pipe may be disturbed or require directional adjustment during the entire construction process, the arc-shaped steel 42 also needs to adjust its direction accordingly. When the ball bearing 43 rolls within the arc-shaped groove 33, the arc-shaped steel 42 rotates accordingly, achieving directional adjustment. The rubber pad 44 prevents long-term friction damage between the downspout hose and the arc-shaped steel 42.

[0031] It should be understood that the specific embodiments described herein are for understanding the present invention only and are not intended to limit the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
