Description

Technical Field

[0001] This application relates to the technical field of water pipeline construction, and in particular to a foundation pit support device for water pipeline construction. Background Technology

[0002] The primary function of water pipelines is to safely and efficiently transport water from water sources to water-using locations, providing urban residents with clean and safe drinking water to meet their production and daily needs. They are an important component of urban infrastructure. Considering factors such as functionality, safety, economy, space utilization, environmental protection, and comfort, water pipelines are typically laid underground. This not only ensures the stability and reliability of the water supply system but also helps improve urban space utilization efficiency and residents' quality of life.

[0003] During the construction of the water pipeline, the ground is excavated along the laying direction of the water pipeline according to the design drawings. The foundation pit for placing the water pipeline is dug out, and then the foundation pit is supported to reduce the risk of collapse. Then, brick supports are built in the foundation pit, the pipeline is placed on the supports and connected end to end in sequence, and the foundation pit support is removed and backfilled.

[0004] Water pipelines are typically formed by connecting multiple pipes. During construction, issues such as the position of the bottom horizontal line of the foundation pit and deviations in the height of the supports can cause height discrepancies when connecting adjacent pipes, increasing the difficulty and workload of the connection process. Summary of the Invention

[0005] This application provides a foundation pit support device for water pipeline construction.

[0006] The technical solution adopted in this application is as follows:

[0007] A foundation pit support device for water pipeline construction includes support plates and support rods. Multiple support plates are symmetrically arranged on the inner wall of the foundation pit and arrayed along the length of the pit. Support rods are connected between two opposing support plates. A support member is installed on the outer wall of each support rod. The support member includes a connecting cylinder sleeved on the outer wall of the support rod, extension rods at both ends of the connecting cylinder, and an adjusting cylinder threaded to the outer wall of the extension rods. The extension rods are parallel to each other and can be used to support the pipeline. A limiting member is provided between the connecting cylinder and the support rod. The connecting cylinder can rotate on the support rod so that the adjusting cylinder is vertically downward or vertically upward, and the connecting cylinder can be positioned by the limiting member.

[0008] By adopting the above technical solution, the support plates are symmetrically arranged on the opposite inner walls of the pit, and support rods are connected between the two opposite inner walls. This allows the support rods to further support the two support plates, improving the stability of the support. The connecting cylinder can rotate on the outer wall of the support rod. When there is a height difference when connecting pipelines, rotating the connecting cylinder makes the two extension rods vertically upward, and the extension rods can support the pipelines. The pipeline height can be adjusted by adjusting the position of the adjusting cylinder. When not in use, the connecting cylinder is rotated so that the extension rods are vertically downward, and the adjusting cylinder is rotated so that the adjusting cylinder abuts against the bottom surface of the pit, allowing the extension rods to support the support rods, further improving the stability of the support.

[0009] Optionally, the limiting member includes limiting blocks symmetrically arranged on the outer wall of the support rod, and the inner wall of the connecting cylinder has a limiting groove extending along the axial direction of the connecting cylinder. The limiting groove and the limiting block correspond to each other, and the limiting block extends in the limiting groove. The inner wall of the connecting cylinder has an annular groove extending along the circumferential direction of the connecting cylinder. One end of the limiting groove is connected to the annular groove. The outer wall of the support rod is provided with an elastic member, which provides a force for the limiting block to abut against the end of the limiting groove away from the annular groove.

[0010] By adopting the above technical solution, the sliding connecting cylinder causes the limiting block to move into the annular groove, thereby enabling the connecting cylinder to rotate; when the limiting block enters the limiting groove, it restricts the rotation of the connecting cylinder, making it difficult for the connecting cylinder to rotate.

[0011] Optionally, the outer wall of the support rod is provided with an annular protrusion, and the elastic element includes a spring sleeved on the outer wall of the support rod. One end of the spring abuts against the annular protrusion, and the other end abuts against the end of the connecting cylinder. When the limiting block is located in the annular groove, the spring is compressed.

[0012] By adopting the above technical solution, the limiting block is not easy to detach from the limiting groove under the elastic force of the spring, thereby improving the stability of the connecting cylinder.

[0013] Optionally, the outer wall of the support rod is provided with a downwardly extending support rod, and the side wall of the connecting cylinder is symmetrically provided with receiving grooves, which extend along the axial direction of the connecting cylinder, and the support rod passes through the receiving grooves; the outer wall of the connecting cylinder is provided with a relief groove extending along the circumferential direction of the connecting cylinder, and when the connecting cylinder slides on the support rod, the support rod can enter the relief groove, and when the connecting cylinder rotates, the support rod can move relative to the relief groove.

[0014] By adopting the above technical solution, the support effect of the support rod can be improved under the action of the support rod, so that the support rod is not easy to bend when the extension rod supports the pipeline; and with the cooperation of the receiving groove and the relief groove, the rotation of the connecting cylinder is not affected.

[0015] Optionally, the end of the adjusting cylinder away from the connecting cylinder is ball-hinged with an abutment plate.

[0016] By adopting the above technical solutions, the contact area between the pipe and the support is increased, thereby improving the support effect on the pipe.

[0017] Optionally, the extension rod has an internal hollow structure, and a reinforcing rod is slidably installed in the extension rod. The side wall of the connecting cylinder has a through hole for the reinforcing rod to slide through, and the side wall of the support rod has an insertion groove. A driving member is provided between the upper end of the reinforcing rod and the inner wall of the extension rod. The driving member is used to drive the end of the reinforcing rod to be inserted into the insertion groove. When the connecting cylinder slides towards the annular protrusion, the reinforcing rod is pressed against the inner wall of the insertion groove and slides into the extension rod, so that the insertion groove is disengaged.

[0018] By adopting the above technical solution, the reinforcing rod is inserted through the through hole and into the insertion groove, thereby improving the stability of the extension rod. This allows the extension rod, connecting cylinder, and support rod to be connected together through the reinforcing rod, improving the stability of the extension rod and connecting cylinder when supporting the pipeline.

[0019] Optionally, the end of the support rod is threadedly connected to a mounting sleeve, and a connecting seat is mounted on the support plate, with the mounting sleeve threadedly connected to the connecting seat.

[0020] By adopting the above technical solutions, the installation of support rods and support plates is simple and quick.

[0021] In summary, this application includes at least one of the following beneficial effects:

[0022] 1. By setting support rods between two support plates, the stability of the support plates is improved. Supporting components are installed on the support rods. When the pipeline needs to be supported, the connecting cylinder is rotated so that the extension rod is vertically upward. The two extension rods can support the pipeline. The height of the pipeline can be adjusted by adjusting the position of the adjusting cylinder.

[0023] 2. Vertical support rods are installed on the support rods, which improve the support effect of the support rods and make the support rods less prone to bending during the pipeline support process. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] This application discloses a foundation pit support device for water pipeline construction. (Refer to...) Figure 1 and Figure 2 The foundation pit support device includes support plates 1 and support rods 2. The support plates 1 are symmetrically installed on the inner wall of the foundation pit and arranged in an array along the length of the foundation pit. Adjacent support plates 1 abut against each other. The support plate 1 includes a vertical plate 101 and a horizontal plate 102, which are perpendicular to each other. The vertical plate 101 abuts against the side wall of the foundation pit, and the horizontal plate 102 abuts against the bottom surface of the foundation pit. The vertical plate 101 and the horizontal plate 102 can be fixed in the foundation pit by means of anchors, ground nails, etc.

[0033] Support rods 2 are symmetrically arranged between two support plates 1, and are horizontally positioned and connected between two opposing vertical plates 101, thereby providing further support to the support plates 1. Preferably, a connecting seat 19 is fixed on the vertical plate 101, and both ends of the support rod 2 are threadedly connected to mounting sleeves 18, which are then threadedly connected to the connecting seats 19, thus enabling both ends of the support rod 2 to support the vertical plate 101. Furthermore, the threads between the mounting sleeves 18 and the connecting seats 19 at both ends of the support rod 2 are in opposite directions, making it less likely for the support rod 2 to rotate and loosen.

[0034] Reference Figure 2 and Figure 3 A support member 3 is installed on the outer wall of the support rod 2. Preferably, the support member 3 is located at the center of the support rod 2, directly below the pipe. The support member 3 includes a connecting cylinder 31 sleeved on the outer wall of the support rod 2, extension rods 32 fixed to the outer walls of both ends of the connecting cylinder 31, and an adjusting cylinder 33 threadedly connected to the outer wall of the extension rods 32. The support rod 2 has a cylindrical structure, and the connecting cylinder 31 has a cylindrical structure. The connecting cylinder 31 is sleeved on the outer wall of the support rod 2, allowing it to rotate or slide. The two extension rods 32 extend radially along the connecting cylinder 31 and are parallel to each other. The distance between the end of the adjusting cylinder 33 and the surface of the connecting cylinder 31 can be adjusted by rotating the adjusting cylinder 33.

[0035] The connecting cylinder 31 has two states. When the connecting cylinder 31 rotates to the position where the extension rod 32 is vertically downward, the end of the adjusting cylinder 33 abuts against the bottom of the pit, allowing the extension rod 32 to support the support rod 2. When the connecting cylinder 31 rotates to the position where the extension rod 32 is vertically upward, the two extension rods 32 can support the pipeline, and the support height of the pipeline can be adjusted by adjusting the adjusting cylinder 33, making it easier to align and connect the pipeline. A limiting member 4 is provided between the connecting cylinder 31 and the support rod 2. When the connecting cylinder 31 rotates, the limiting member 4 positions the connecting cylinder 31, making it less likely to rotate further.

[0036] Combined Figure 4 and Figure 5 The limiting component 4 includes a limiting block 41 fixed to the outer wall of the support rod 2, with the limiting blocks 41 symmetrically arranged on the outer wall of the support rod 2. A limiting groove 5 is formed on the inner wall of the connecting cylinder 31, extending along the axial direction of the connecting cylinder 31. The limiting groove 5 and the limiting block 41 correspond one-to-one, and the limiting block 41 extends into the limiting groove 5. When the connecting cylinder 31 slides on the support rod 2, the limiting block 41 slides relative to it in the limiting groove 5, and under the action of the limiting block 41 and the limiting groove 5, the connecting cylinder 31 cannot rotate on the support rod 2. An annular groove 6 is formed on the inner wall of the connecting cylinder 31, extending circumferentially along the connecting cylinder 31, and one end of the limiting groove 5 is connected to the annular groove 6. After the limiting block 41 enters the annular groove 6, the connecting cylinder 31 can rotate.

[0037] Furthermore, an elastic element 7 is installed between the support rod 2 and the connecting cylinder 31. The elastic element 7 is used to drive the limiting block 41 to abut against the inner wall of the limiting groove 5 away from the annular groove 6. When it is necessary to rotate the connecting cylinder 31, the sliding connecting cylinder 31 causes the limiting block 41 to enter the annular groove 6, and at this time the elastic element 7 is in a compressed state.

[0038] Reference Figure 3-5An annular protrusion 8 is coaxially fixed to the outer wall of the support rod 2. The elastic element 7 includes a spring sleeved on the outer wall of the support rod 2. One end of the spring abuts against the annular protrusion 8, and the other end abuts against the end face of the connecting cylinder 31. When the connecting cylinder 31 slides towards the annular protrusion 8, the limiting block 41 can enter the annular groove 6, and the spring is compressed. Under the action of the spring, the limiting block 41 can abut against the inner wall of the end of the limiting block 41 away from the annular groove 6. The limiting block 41 can restrict the rotation of the connecting cylinder 31, and the limiting block 41 is not easy to disengage from the limiting groove 5. In order to improve the stability of the connecting cylinder 31, two sets of limiting elements 4 are provided, which are located at both ends of the connecting cylinder 31 respectively.

[0039] Furthermore, in combination Figure 6 The outer wall of the support rod 2 has a support rod 9, which extends vertically downwards. A support sleeve 20 is threadedly connected to the end of the support rod 9 furthest from the support rod 2. Rotating the support sleeve 20 allows it to abut against the bottom of the pit. A receiving groove 10 is formed on the outer wall of the connecting cylinder 31, extending along the axis of the connecting cylinder 31. The support rod 9 passes through the receiving groove 10. A clearance groove 11 is formed on the outer wall of the connecting cylinder 31, extending circumferentially. When the connecting cylinder 31 slides, the support rod 9 can enter the clearance groove 11 from the receiving groove 10. When the connecting cylinder 31 rotates, the support rod 9 can move relative to the clearance groove 11. The support rod 9 enhances the stability of the support rod 2 when supporting the pipeline. Furthermore, to improve the pipeline support effect, a contact plate 12 is ball-hinged at the end of the adjusting cylinder 33 furthest from the extending rod 32, thereby increasing the contact area with the pipeline.

[0040] Reference Figure 4 and Figure 5 The extension rod 32 is welded to the outer wall of the connecting cylinder 31, and the extension rod 32 has an internal hollow structure. A through hole 14 is provided in the connecting cylinder 31 corresponding to the inner cavity of the extension rod 32. A reinforcing rod 13 is slidably installed in the extension rod 32, with one end of the reinforcing rod 13 slidably passing through the through hole 14. An insertion groove 15 is provided on the outer wall of the support rod 2 for inserting the end of the reinforcing rod 13. When the connecting cylinder 31 rotates to a vertically upward position on the extension rod 32, the reinforcing rod 13 can be inserted into the insertion groove 15, and a driving member 16 is installed in the extension rod 32 to drive the end of the reinforcing rod 13 to abut against the insertion groove 15. The driving member 16 is preferably a spring.

[0041] The bottom of the insertion groove 15 is inclined upwards towards the annular protrusion 8. When the connecting cylinder 31 moves towards the annular protrusion 8, the end of the reinforcing rod 13 moves uphill in the insertion groove 15 and gradually slides out of the insertion groove 15, so that the reinforcing rod 13 does not affect the rotation of the connecting cylinder 31. Under the action of the reinforcing rod 13, the extension rod 32, the connecting cylinder 31 and the support rod 2 are connected together, thereby improving the stability when supporting the pipeline.

[0042] The implementation principle of the foundation pit support device for water pipeline construction in this application embodiment is as follows: under the action of the support rod 2, the support effect on the support plate 1 is improved. When the adjusting cylinder 33 abuts against the bottom surface of the foundation pit, it can improve the stability of the support rod 2. When the pipeline needs to be adjusted and supported in the height direction during pipeline connection, the connecting cylinder 31 is rotated until the extension rod 32 is vertically upward, and the two adjusting cylinders 33 can support the pipeline.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
