This not only impacts the HDPE pipes' ability to deliver water, but also requires frequent repairs and replacements, increasing maintenance costs and wasting resources. In some cities near the edge of the desert, the impact of quicksand shortens the lifespan of HDPE pipes, leading to frequent leaks and other issues, severely impacting the city's water supply security and residents' quality of life.

DETAILED DESCRIPTION
[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0017] See also Figure 1 The anti-floating and stable installation structure for HDPE pipes in a quicksand geological environment provided by the present invention will now be described. The anti-floating and stable installation structure for HDPE pipes in a quicksand geological environment comprises a fixed clamping unit 10, an anti-floating mechanism 20, and a transverse connecting mechanism 30. The fixed clamping unit 10 has a receiving cavity and a through hole 111 that is connected to the receiving cavity and for the HDPE pipe 40 to pass through. The receiving cavity has a clamping portion for clamping and fixing the HDPE pipe 40. There are multiple anti-floating mechanisms 20, each of which is spaced apart along the axial direction of the through hole 111, and each anti-floating mechanism 20 has a connecting hole for the HDPE pipe 40 to pass through. Each anti-floating mechanism 20 has a fastening portion that can be fixed to the surrounding soil. The transverse connecting mechanism 30 can fixedly connect the fixed clamping unit 10 and each anti-floating mechanism 20.
[0018] Compared to the prior art, the anti-floating and stable installation structure for HDPE pipes in quicksand geological environments provided in this embodiment utilizes a fixed clamping unit 10 and each anti-floating mechanism 20, via a transverse connecting mechanism 30, to form an installation structure of a certain length. This ensures long-distance fixation of the HDPE pipe 40, increases the contact area of the HDPE pipe 40 in the quicksand geological environment, and thus ensures the stability of the HDPE pipe 40. The fixed clamping unit 10 can securely clamp the HDPE pipe 40 via the clamping portion within the accommodating cavity, thereby ensuring that the HDPE pipe 40 is positioned axially and radially, effectively preventing axial or radial displacement of the HDPE pipe 40. The multiple anti-floating mechanisms 20 can provide multi-point support for the HDPE pipe 40 to ensure that the HDPE pipe 40 is subjected to uniform force. At the same time, the anti-floating mechanism 20 can also be fixed to the soil, which can effectively prevent the HDPE pipe 40 from being deformed due to the buoyancy of the soil, and thus effectively prevent the HDPE pipe 40 from being broken. It can effectively ensure the stability of the HDPE pipe 40 in the quicksand geological environment, extend the service life of the HDPE pipe 40, and is highly practical.
[0019] In this embodiment, the anti-floating mechanisms 20 can be evenly distributed on both sides of the fixed clamping unit 10, or only placed on one side of the fixed clamping unit 10, and can be randomly adjusted according to the actual construction environment.
[0020] In some embodiments, the fixed clamping unit 10 may be configured as follows: Figures 2 to 4 The structure shown. Figures 2 to 4 The fixed clamping unit 10 includes a shell 11, a limiting slide 12, a first slide 13, a second slide 14, a driving structure 15 and a linkage structure 16. The shell 11 has an inner cavity, which is a accommodating cavity. The through hole 111 is located on the shell 11. The horizontal direction perpendicular to the axis of the through hole 111 is set as the first direction. There are multiple limiting slides 12, and each limiting slide 12 is arranged in the accommodating cavity along the first direction. The first slide 13 is slidably connected to each limiting slide 12 and is located on one side of the through hole 111 along the first direction. A first arc-shaped clamping opening 131 is provided at the end of the first slide 13 close to the through hole 111. The second slide 14 is slidably connected to each limiting slide 12 and is located on the other side of the through hole 111 along the first direction. A second arc-shaped clamping opening 141 is provided at the end of the second slide 14 close to the through hole 111. The second slide 14 and the first slide 13 are combined to form a clamping portion. The drive structure 15 is disposed on the housing 11 and is in dynamic connection with the first slide 13. The linkage structure 16 is disposed in the accommodating cavity and is connected to the first slide 13 and the second slide 14, respectively. After the drive structure 15 drives the first slide 13 to move, it can drive the second slide 14 to move relative to or away from the first slide 13.
[0021] Specifically, the driving structure 15 can drive the first slide 13 to slide on each limiting slide rod 12, approaching or moving away from the through-hole 111. When the first slide 13 approaches the through-hole 111, the linkage structure 16 connected to the first slide 13 drives the second slide 14 to move synchronously, and the second slide 14 also approaches the through-hole 111. The first slide 13 and the second slide 14 move relative to each other. At this time, the first arc-shaped clamping opening 131 on the first slide 13 and the second arc-shaped clamping opening 141 on the second slide 14 can clamp the HDPE pipe 40 on both sides of the through-hole 111, thereby securing the HDPE pipe 40. When the first slide 13 moves away from the through-hole 111, the linkage structure 16 connected to the first slide 13 drives the second slide 14 to move synchronously, and the second slide 14 also moves away from the through-hole 111. The first slide 13 and the second slide 14 move away from each other, thereby releasing the clamping of the HDPE pipe 40.
[0022] In this embodiment, the first slide 13 is driven by the driving structure 15, and the second slide 14 is driven to move synchronously by the linkage structure 16 connected to the first slide 13, which can ensure the relative or opposite movement of the first slide 13 and the second slide 14, thereby ensuring the fixed clamping effect of the HDPE pipe 40, and effectively ensuring the fixation of the HDPE pipe 40, thereby adapting to the quicksand geological environment.
[0023] In some embodiments, the driving structure 15 may be configured as follows: Figures 3 and 4 The structure shown. Figures 3 and 4 The drive structure 15 includes a screw 151 and a rotating handle 152. The screw 151 is arranged along the first direction and is rotatably connected to the housing 11. The screw 151 is screw-engaged with the nut on the first slide 13. The rotating handle 152 is connected to one end of the screw 151 and can drive the screw 151 to rotate.
[0024] The screw 151 is spirally connected to the first slide 13 to ensure that the screw 151 drives the first slide 13 to move, and rotating the handle 152 can ensure manual adjustment of the screw 151. It has a simple structure and strong practicality, which makes it convenient for staff to manually fix and clamp the HDPE pipe 40.
[0025] In some embodiments, the fixed clamping unit 10 may be configured as follows: Figure 5 The structure shown. Figure 5The fixed clamping unit 10 also includes a self-locking structure 17, which includes a fixed plate 171, a ratchet 172 and a pawl 173. The fixed plate 171 is arranged in the accommodating cavity and is fixedly connected to the housing 11. The fixed plate 171 has a through hole for the screw 151 to pass through. An installation space is formed between the fixed plate 171 and the inner wall of the accommodating cavity. The ratchet 172 is located in the installation space and is coaxially connected to the screw 151. The pawl 173 is arranged on the fixed plate 171 and engages with the ratchet 172, and can unidirectionally lock the ratchet 172 when the screw 151 drives the first slide 13 to move close to the through hole 111.
[0026] The screw 151 is screwed together with the nut on the first slide 13. The screw 151 can drive the first slide 13 to move, and the first slide 13 and the second slide 14 can jointly fix and clamp the HDPE pipe 40. After clamping, the screw 151 can be locked by the self-locking structure 17 to prevent the screw 151 from rotating in the opposite direction due to the opposing force from the first slide 13 and the second slide 14. This structure can effectively ensure stable clamping of the HDPE pipe 40 and is highly practical.
[0027] It should be noted that the coordination between the ratchet 172 and the pawl 173 is a prior art and well known to those skilled in the art, and will not be described in detail here. Figure 2 A push rod is provided on the housing 11 to adjust the pawl 173 to ensure that the pawl 173 releases the self-locking effect on the ratchet 172.
[0028] In some embodiments, the linkage structure 16 may be configured as follows: Figures 3 and 4 The structure shown. Figures 3 and 4 The linkage structure 16 includes an intermediate rotating rod 161 and a connecting rod 162. The intermediate rotating rod 161 is located at the bottom of the accommodating cavity and is rotatably connected to the housing 11, with the rotation axis arranged along the vertical direction. The intermediate rotating rod 161 has two connecting ends extending in opposite directions. Two connecting rods 162 are provided, one end of which is rotatably connected to the first slide 13 and the other end is rotatably connected to one of the connecting ends. The other connecting rod 162 has one end rotatably connected to the second slide 14 and the other end is rotatably connected to the other connecting end.
[0029] The midpoint of the rotating rod is rotatably connected to the housing 11, and the axis of rotation is along the vertical direction. The two ends of the rotating rod are respectively connected to connecting rods 162. The two connecting rods 162 are connected to the first slide 13 and the second slide 14. This structure ensures that after the first slide 13 moves, it can drive the rotating rod to rotate through one of the connecting rods 162, and then the rotating rod will drive the other connecting rod 162 to pull or push the second slide 14 to move, realizing the synchronous relative or opposite movement of the first slide 13 and the second slide 14. The structure is simple and practical, and can ensure effective fixation and clamping of the HDPE pipe 40, thereby ensuring adaptation to quicksand geological environments.
[0030] In some embodiments, the anti-floating mechanism 20 may be implemented as follows: Figure 6 The structure shown. Figure 6 Each anti-floating mechanism 20 includes a fixed block 21 and an expansion structure 22. The fixed block 21 has a connection hole. There are multiple expansion structures 22, each of which is arranged at the bottom of the fixed block 21 and is combined to form a fastening portion.
[0031] The fixing block 21 can be connected to the HDPE pipe 40 through the provided connection hole, and can also achieve the fixation of the HDPE pipe 40. The expansion structure 22 at the bottom of the fixing block 21 can be fixedly connected with the soil below, or increase the contact area with the soil, thereby ensuring the stability of the fixing block 21 and the stability of the HDPE pipe 40, ensuring that the HDPE pipe 40 has a good anti-floating effect.
[0032] The fixing block 21 may include two half-shaped blocks that can be matched together. After the two half-shaped blocks are matched together and clamp the HDPE pipe 40, they can be locked and connected by bolts.
[0033] In some embodiments, the expansion structure 22 may be formed as follows: Figure 7 The structure shown. Figure 7Each expansion structure 22 includes a cylinder 221, a screw 222, a sliding ring 224, an external support claw 226 and a pull rod 227. The cylinder 221 is vertically fixed to the bottom end of the fixed block 21, and a tapered portion is provided at the bottom end of the cylinder 221. At least two vertical long strips are provided on the side wall of the cylinder 221, and each vertical long strip is connected to the barrel cavity of the cylinder 221. The screw 222 is coaxially arranged with the cylinder 221 and is rotatably connected to the cylinder 221. A rotary valve 223 is provided at the protruding end of the screw 222. The sliding ring 224 is arranged in the barrel cavity of the cylinder 221, and the sliding ring 224 is threadedly connected to the screw 222. A plurality of adapters that can correspond one-to-one to each vertical long strip are provided on the sliding ring 224. A limiting slider 225 that slides with the inner wall of the barrel cavity is provided on the sliding ring 224. There are multiple external support claws 226, each of which is positioned in each vertical elongated opening. The bottom end of each external support claw 226 is rotatably connected to the bottom end of the corresponding vertical elongated opening. There are multiple pull rods 227, each of which corresponds to a corresponding external support claw 226. One end of each pull rod 227 is rotatably connected to the corresponding pull rod 227, and the other end is rotatably connected to the corresponding adapter.
[0034] The cylinder 221 can be inserted into the soil through the conical part at the bottom. After the cylinder 221 is inserted into the soil, the screw 222 can be driven to rotate by rotating the valve 223. After the screw 222 rotates, it can drive the sliding ring 224 to move vertically in the cylinder cavity. When the sliding ring 224 moves downward, it can push each outer support claw 226 to flip through each pull rod 227. Each outer support claw 226 can use the hinge point at its bottom as the axis and the top end to pitch downward, thereby moving the top end of the outer support claw 226 into the soil, increasing the contact range with the soil, and at the same time forming a limit in the vertical direction, which can effectively ensure the stability of the fixed block 21 and ensure the stability and anti-floating effect of the HDPE pipe 40.
[0035] The limiting slider 225 provided on the sliding ring 224 can be connected to the limiting groove on the inner wall of the cylinder cavity in a limiting sliding manner, thereby preventing the sliding ring 224 from rotating.
[0036] In some embodiments, the transverse connection mechanism 30 may be configured as follows: Figure 1 The structure shown. Figure 1 The transverse connecting mechanism 30 includes multiple connectors, each of which is disposed in the spaces formed between the fixed clamping unit 10 and each anti-floating mechanism 20. Each connector includes two right-angled stabilizing plates 31, which are located on either side of the HDPE pipe 40. The two ends of each right-angled stabilizing plate 31 are connected to two adjacent anti-floating mechanisms 20, or to an adjacent fixed clamping unit 10 and anti-floating mechanism 20.
[0037] Each connector includes two right-angled stabilizing plates 31 distributed on both sides of the HDPE pipe 40. Each connector can ensure that the fixed clamping unit 10 and the anti-floating mechanism 20 are connected to form an installation structure with a certain length, thereby increasing the fixed length of the HDPE pipe 40 and increasing the contact area, thereby effectively preventing the HDPE pipe 40 from displacement, deformation or rupture.
[0038] Each connector includes two right-angled stabilizing plates 31, which extend outward a certain distance to further increase the contact area with the soil and ensure stability. Each right-angled stabilizing plate 31 also has a certain length in the vertical direction, which enhances structural strength and further increases the contact area with the soil, thereby ensuring the stability of the HDPE pipe 40.
[0039] It should be noted that each right-angled stabilizing plate 31 can be formed by bolting two plates arranged at right angles to each other, as shown in FIG. Figure 1 In addition, multiple auxiliary plates can be arranged at intervals on the surface of each plate body to ensure that the contact area with the soil and the friction with the soil are further increased.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
