Description

TECHNICAL FIELD

[0001] The utility model relates to the field of foundation pit construction, especially to a foundation pit dewatering well pipe structure. BACKGROUND

[0002] When constructing underground buildings, such as subway projects, a dewatering well is usually constructed to extract groundwater in the pipe well to lower the water level of the groundwater, thereby ensuring the smooth progress of excavation, opening and other construction, and also making the soil layer relatively dry, which is conducive to the smooth progress of construction.

[0003] In the prior art, the dewatering well usually needs to dig a foundation pit, and then connect and insert multiple sections of steel pipes or plastic pipes as well pipe pipes into the foundation pit in sequence, wherein the outer wall of both ends of the pipe is provided with a plurality of bolt holes, and the two pipes are connected by a plurality of bolt holes when connected, and after the pipes are fully inserted into the foundation pit, a filter layer such as filter material is filled between the gap between the pipes and the foundation pit, wherein the pipe at the bottom is also called a filter pipe, and after the groundwater is filtered through the filter layer, it enters the pipe through the filter pipe, and finally a water pipe connected with a water pump is arranged in the pipe to extract the groundwater, wherein a well cover, a retaining wall and other protective structures are arranged on the top of the well pipe, and some accessories such as valves, flow meters, etc. can also be arranged according to requirements.

[0046] Embodiment 1

[0047] It should be understood that in the construction of the precipitation well, if the connection between the two pipes 200 is unstable, a gap will appear between the pipes 200, which will cause the underground water entering the pipe 200 to overflow from the gap, thereby affecting the precipitation effect, and also, the impurities such as silt or particles will enter the pipe 200 through the gap, thereby accumulating in the pipe 200, and finally clogging the filter pipe. In addition, the unstable pipe 200 is prone to collapse and subsidence of the precipitation well.

[0048] Therefore, in order to ensure the stable connection of the pipe 200, a plurality of bolts are usually arranged at the connection of the two pipes 200, and the two pipes 200 are stably connected by the plurality of bolts. However, as the size of the pipe 200, diameter and the like increases, more bolts are needed to ensure the stable connection of the pipe 200, thereby causing the connection of the pipe 200 to be time-consuming and labor-intensive, and the efficiency is low.

[0049] Therefore, in order to improve the above problems, the present embodiment provides a foundation pit 100 precipitation well pipe structure, mainly comprising a foundation pit 100, a plurality of pipes 200 and a plurality of clamping sleeves. The structure makes the connection of the pipes 200 of the precipitation well more efficient, and the connection between the pipes 200 is stable.

[0050] The precipitation well is usually dug at a specified position to form a foundation pit 100, a protective device such as a fence or a wall is arranged on the top of the foundation pit 100, and then a pipeline 200 is inserted into the foundation pit 100 in sequence, wherein, before the first section of the pipeline 200 is inserted, a concrete blind pipe 800 can be arranged in the foundation pit 100, and then the pipeline 200 is arranged on the concrete blind pipe 800, wherein, the pipeline 200 can be provided with a filter structure such as a filter hole according to requirements, and then a filter layer 300 is formed by filling filter material between the outer wall of the pipeline 200 and the inner wall of the foundation pit 100, and then a water pumping pipe 700 is placed in the pipeline 200 to pump water, and the water pumping pipe 700 is connected with a water pump, since the precipitation well is prior art, the installation steps of the precipitation well and the rest of the structures arranged according to requirements will not be described in detail.

[0051] As shown in the embodiment, Figure 1 The pipeline 200 is provided with a plurality of elastic clamping pieces 400 at both ends, the elastic clamping pieces 400 are arranged in sequence and at intervals along the outer wall of the pipeline 200, wherein, the interval and the number of the elastic clamping pieces 400 can be selected according to the weight and diameter of the pipeline 200, for example, the larger the weight and the diameter of the pipeline 200, the smaller the interval between the elastic clamping pieces 400, and the more the number of the elastic clamping pieces 400.

[0052] As shown in the embodiment, Figures 1-5 The elastic clamping piece 400 includes a clamping block 410 and a compression spring 420, the outer wall of both ends of the pipeline 200 is provided with a plurality of grooves 230 in sequence and at intervals in the circumferential direction, the grooves 230 are adapted to the clamping block 410, a plurality of compression springs 420 are arranged in the plurality of grooves 230 respectively, the two ends of the compression spring 420 are connected with the inner wall of the groove 230 and the outer wall of the clamping block 410 respectively, and the clamping block 410 and the compression spring 420 are inserted into the groove 230 in the direction perpendicular to the axial direction of the pipeline 200, wherein, the compression spring 420 can drive the clamping block 410 to displace relative to the groove 230 when the compression spring 420 is contracted and stretched.

[0053] The clamping sleeve can adopt a polygonal structure such as a cylinder or a rectangular body, which can be selected according to the shape of the pipeline 200, in the embodiment, in order to insert the pipeline 200 into the clamping sleeve, the clamping sleeve adopts a cylindrical structure, wherein, the clamping sleeve is adapted to the pipeline 200, so that the pipeline 200 can be inserted into the clamping sleeve.

[0054] As shown in the embodiment, Figures 6-8 The inner wall of the clamping sleeve is provided with a plurality of clamping grooves 510, the plurality of clamping grooves 510 are evenly arranged on the inner wall of both ends of the clamping sleeve, wherein, the plurality of clamping grooves 510 on the same end of the clamping sleeve are arranged in sequence and at intervals along the circumferential direction of the inner wall of the clamping sleeve, and the clamping groove 510 is adapted to the clamping block 410.

[0055] The one end of the clamping block 410 away from the compression spring 420 can adopt a ball structure, a pulley structure or directly set the one end of the clamping block as an arc surface structure, thereby reducing the friction between the clamping block 410 and the inner wall of the clamping sleeve. In the embodiment, the one end of the clamping block 410 adopts an arc surface structure.

[0056] As shown in the figure, Figures 1-8 When the two pipes 200 are connected, the one ends of the two pipes 200 are inserted into the two ends of the clamping sleeve 500 respectively. At this time, the arc-shaped one end of the clamping block 410 abuts against the inner wall of the clamping sleeve 500, and the other end of the clamping block 410 extrudes the compression spring 420. The compression spring 420 is in a contracted state due to extrusion. When the clamping block 410 on the pipe 200 is driven by the pipe 200 and displaced to the clamping groove 510, the abutment of the clamping block 410 against the inner wall of the clamping sleeve 500 disappears, thereby making the extrusion force of the inner wall of the clamping sleeve 500 on the clamping block 410 disappear, so that the extrusion force of the clamping block 410 on the compression spring 420 decreases. The compression spring 420 is stretched, thereby driving the clamping block 410 to be inserted into the clamping groove 510 along the axial direction of the clamping groove 510. At this time, the clamping block 410 is attached to the inner wall of the clamping groove 510, and when the clamping block 410 is clamped in the clamping groove 510, the end faces of the two pipes 200 are attached and abutted.

[0057] When the two pipes 200 are connected, the inner wall of the clamping sleeve 500 abuts against the outer wall of the pipe 200, so that the inner wall of the clamping sleeve 500 supports the two pipes 200, and the supporting area is large, thereby making the connection of the two pipes 200 stable. Meanwhile, the clamping sleeve 500 can protect the outer wall of the connection of the two pipes 200, preventing the two pipes 200 from being damaged due to collision with the soil layer or the filter layer 300.

[0058] As shown in the figure, Figure 1 The end face of the pipe 200 is provided with a sealing gasket 600. The sealing gasket 600 is consistent with the shape and structure of the end face of the pipe 200. The sealing gasket 600 can be made of rubber. The diameter of the sealing gasket 600 is consistent with the diameter of the barrel opening of the clamping sleeve 500. When the pipe 200 is inserted into the clamping sleeve 500, the diameter of the sealing gasket 600 is consistent with the diameter of the clamping sleeve 500, and the sealing gasket 600 is made of rubber and has a certain elasticity. Therefore, the circumferential outer wall of the sealing gasket 600 is closely attached to the inner wall of the clamping sleeve 500, thereby having a good sealing and waterproof effect.

[0059] After the two pipes 200 are inserted into the clamping sleeve 500, the sealing gaskets 600 of the end faces of the two pipes 200 are attached and abutted.

[0060] As shown in the figure, Figure 1As shown, the diameter of the end of the sealing gasket 600 away from the pipe 200 decreases successively along the direction in which the pipe 200 is inserted into the clamping sleeve 500, wherein the diameter of the end of the sealing gasket 600 away from the pipe 200 is the smallest, and the diameter size is slightly smaller than the diameter of the barrel mouth of the clamping sleeve 500, so that the pipe 200 can be inserted into the clamping sleeve 500 more easily.

[0061] In this embodiment, Figure 1 、 Figure 6 、 Figure 7 and Figure 8 As shown, the inner wall of the clamping sleeve is provided with multiple first slide grooves 520 and multiple second slide grooves 530, and a first slide groove 520 is provided between two adjacent clamping grooves 510 at the same end, wherein the two ends of the first slide groove 520 are respectively connected to the two clamping grooves 510, and the multiple first slide grooves 520 at the same end are located in the same horizontal plane, and the multiple first slide grooves 520 are arranged in sequence along the inner wall of the clamping sleeve, one end of the multiple second slide grooves 530 is respectively connected to the multiple first slide grooves 520, and the notches at the other ends of the multiple second slide grooves 530 are set on the end face of the pipe 200, specifically, the extension direction of the second slide groove 530 is consistent with the axial direction of the pipe 200, and the multiple second slide grooves 530 are arranged in sequence along the circumferential direction of the inner wall of the pipe 200, wherein the first slide groove 520 and the second slide groove 530 are adapted to the clamping block 410.

[0062] In this embodiment, when the pipe 200 is inserted into the clamping sleeve 500, the clamping block 410 slides along the second slide groove 530. As the pipe 200 is inserted, the clamping block 410 slides along the second slide groove 530 to the first slide groove 520, and then slides along the first slide groove 520 to the clamping groove 510, so that when the pipe 200 is inserted into the clamping sleeve 500, the second slide groove 530 can be used as a positioning, and the first slide groove 520 and the second slide groove 530 work together to make the insertion of the pipe 200 simple and the insertion position accurate.

[0063] The second sliding groove 530 is disposed at the center of the first sliding groove 520 , so that two ends of the first sliding groove 520 are symmetrical with respect to the second sliding groove 530 .

[0064] Since both the left and right ends of the first sliding groove 520 are connected to the clamping groove 510 , the clamping block 410 can slide toward any one of the two ends of the first sliding groove 520 .

[0065] In this embodiment, the concrete blind pipe 800 is adapted to the pipeline 200 .

[0066] Example 2

[0067] According to the foundation pit 100 dewatering well pipe structure provided by the above embodiment, in order to further improve the connection stability between the two pipes 200, as shown in FIG. Figures 1-5As shown, the pipeline 200 is provided with a plurality of butt sliding grooves 210 and a plurality of butt elastic members 220. The plurality of butt sliding grooves 210 are sequentially and spacedly arranged on the end face of one end of the pipeline 200. The plurality of butt elastic members 220 are sequentially and spacedly arranged on the end face of the other end of the pipeline 200. The butt sliding groove 210 is matched with the butt elastic member 220. The butt sliding groove 210 is a T-shaped groove.

[0068] The butt elastic member 220 comprises a butt block 221, a butt spring 222 and a butt plate 223. The plurality of butt blocks 221 are sequentially and spacedly arranged on the end face of one end of the pipeline 200. Specifically, the butt block 221 is connected with the end face of the pipeline 200 through the sealing gasket 600. The butt block 221 is provided with the butt spring 222 at one end of the pipeline 200. The butt spring 222 is provided with the butt plate 223 at one end.

[0069] The plurality of butt sliding grooves 210 are sequentially and spacedly arranged on the end face of the other end of the pipeline 200. The butt sliding groove 210 is provided with a notch on the side facing the other pipeline 200. Specifically, the size of one end of the notch is larger than that of the other end.

[0070] In this embodiment, the size of one end of the butt block 221, the butt plate 223 and the butt spring 222 is matched with the size of the larger notch of the butt sliding groove 210. The size of the other end of the butt block 221 is matched with the size of the smaller notch of the butt sliding groove 210.

[0071] When the two pipelines 200 are connected, the end faces of the two pipelines 200 abut. At this time, one end of the butt plate 223, the butt spring 222 and the butt block 221 is inserted into the notch of the butt sliding groove 210. Then, with the rotation of the pipeline 200, the butt plate 223, the butt spring 222 and the butt block 221 are displaced along the notch of the butt sliding groove 210 to the smaller notch. At this time, the butt plate 223 abuts against the inner wall of the butt sliding groove 210, and the butt spring 222 is in a compressed state. The butt spring 222 generates an extrusion force on the butt block 221, so that the outer wall of the larger end of the butt block 221 abuts against the inner wall of the notch, thereby making the connection between the two pipelines 200 more stable.
