Description

Technical Field

[0001] The utility model belongs to the technical field of precipitation well supports, in particular to a precipitation well support in fine sand geology. Background Art

[0002] Fine sand geological dewatering well is an engineering well specially designed for dewatering (pumping water) in fine sand or similar loose soil layers. Its main purpose is to lower the groundwater level by extracting groundwater, preventing surface water accumulation or instability of the foundation soil layer in the construction area. It is usually used in engineering projects such as subways, foundation pit excavation, and basements.

[0003] In fine sand geology precipitation wells, the support structure is one of the key components, used to support the well pipe, fix equipment and maintain the stability of the well wall. At present, there are some precipitation well support structures on the market, such as a precipitation well pipe support support with the announcement number CN204849792U disclosed on the China Patent Network. This support structure can be used for fine sand geology precipitation wells, but there are some defects and deficiencies that need to be improved: (1) Due to structural design reasons, most of the existing precipitation well supports are fixed to the ground by a single fastener such as screws, and the contact area with the ground is small, which makes the support structure unstable and will become loose over time; (2) Some existing precipitation well supports lack effective reinforcement measures. The support structure is prone to bending and deformation after being subjected to stress for a long time, resulting in the precipitation well lacking sufficient support and fixation, and then breaking under the action of external force. Therefore, in response to the above problems, the fine sand geology precipitation well support provided by the utility model is of great significance. Utility Model Content

[0004] The utility model provides a fine sand geological precipitation well support, which can fix the base together with the entire support structure on the ground where the fine sand geological precipitation well is located through a screw, and the bottom end of the screw is in the shape of a spike, which can be inserted into the soil of the fine sand geological ground so that the screw can be firmly fixed to the ground, thereby improving the stability of the base and preventing it from loosening. The anti-skid patterns on the surface of the anti-skid pad can increase the friction between the base and the ground to play an anti-skid role, thereby effectively preventing the base from slipping and displacement and affecting the stability of the precipitation well support; the structural strength of the casing can be effectively enhanced by the reinforcement rods in the multiple reinforcement cavities to prevent the casing from bending and deforming after being subjected to force for a long time, thereby causing the well pipe of the precipitation well to rupture under the action of external force; the compression and deformation resistance of each connecting block can be enhanced by the reinforcement ribs to prevent the connecting block from bending and deforming and affecting the stability of the precipitation well support; the structural strength of the precipitation well support can be further improved by the multiple reinforcement blocks to increase its service life. In summary, the problems in the background technology are solved.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0012] Furthermore, a plurality of filter ports are provided at the bottom end of the casing, and the filter ports are distributed in an equidistant annular pattern along the circumference of the casing, and a filter screen is installed in each of the filter ports.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When the fine sand geological precipitation well support in the utility model is used, the base together with the entire support structure can be fixedly installed on the ground where the fine sand geological precipitation well is located by a screw. The bottom end of the screw is in the shape of a spike and can be inserted into the soil of the fine sand geological ground so that the screw can be firmly fixed to the ground, thereby improving the stability of the base and preventing it from loosening.

The compression and deformation resistance of each connecting block can be enhanced by the reinforcement ribs to prevent the connecting blocks from bending and deforming and affecting the stability of the precipitation well support.

A casing 7 is provided between the base 3 and the well pipe 1, and the casing 7 is laid in the ground and sleeved on the outside of the well pipe 1, and a plurality of connecting blocks 8 are fixedly connected between the outer wall of the casing 7 and the inner wall of the base 3. The casing 7 can be used to support the well pipe 1 of the precipitation well to maintain the stability of the well wall of the well pipe 1 and prevent collapse at the wellhead.

[0029] Among them, the mounting seats 4 are distributed in an equidistant ring shape along the circumferential direction of the base 3, and the bottom end of the screw 6 is in a spike shape, which can be inserted into the soil of the fine sand geological ground, so that the screw 6 can be firmly fixed to the ground, thereby improving the stability of the base 3 and preventing it from loosening.

[0030] Among them, the bottom surface of the base 3 is provided with an anti-slip pad 9, which is annular and has a herringbone anti-slip pattern engraved on its surface. The anti-slip pad 9 is made of elastic material such as rubber and is fixed by glue or other means. When the base 3 is fixed to the ground by the screw 6, the anti-slip pattern on the surface of the anti-slip pad 9 can increase the friction between the base 3 and the ground to play an anti-slip role, thereby effectively preventing the base 3 from slipping and displacing and affecting the stability of the precipitation well bracket.

[0031] Among them, a number of reinforcement cavities 10 are opened inside the casing 7, and the reinforcement cavities 10 are equidistantly distributed in annular shapes along the circumferential direction of the casing 7, and a reinforcement rod 11 is provided in each reinforcement cavity 10. The reinforcement rods 11 in multiple reinforcement cavities 10 can effectively enhance the structural strength of the casing 7 to prevent the casing 7 from bending and deforming after being subjected to stress for a long time, thereby preventing the well pipe 1 of the precipitation well from rupturing under the action of external force.

When the base 3 is fixed to the ground by the screw rod 6, the anti-skid pattern on the surface of the anti-skid pad 9 can increase the friction between the base 3 and the ground to play an anti-skid role, thereby effectively preventing the base 3 from slipping and displacement and affecting the stability of the precipitation well bracket. When the precipitation well bracket is installed and fixed, the casing 7 can be laid in the ground and sleeved on the outside of the well pipe 1. At this time, the casing 7 can be used to support the well pipe 1 of the precipitation well to maintain the well pipe 1, the well wall is stable to prevent collapse at the wellhead. Several reinforcement cavities 10 are opened inside the casing 7, and each reinforcement cavity 10 is provided with a reinforcement rod 11.

Several connecting blocks 8 are fixedly connected between the outer wall of the casing 7 and the inner wall of the base 3, and reinforcing ribs 12 are fixedly connected between each adjacent two connecting blocks 8.
