[0002] The main function of water pipelines is to safely and efficiently transport water from water sources to water use locations, provide clean and safe drinking water for urban residents, and meet people's production and living needs. It is an important part of urban infrastructure. For comprehensive considerations of functionality, safety, economy, space utilization, environmental protection, and comfort, water pipelines are usually buried underground, which not only ensures the stability and reliability of the water supply system, but also helps to improve the space utilization efficiency of the city and the quality of life of residents.

[0003] During the construction of the water pipeline, according to the design drawings, ground excavation is carried out along the laying direction of the water pipeline to dig out a foundation pit for placing the water pipeline. The foundation pit is then supported to reduce the risk of collapse. Next, piers are built with bricks in the foundation pit, and the pipeline is placed on the piers and connected end to end in sequence. The foundation pit support is then removed and backfilled.

[0004] Water pipelines are usually formed by connecting multiple pipes. During the construction process, due to the position of the horizontal line of the foundation pit bottom and the height deviation of the piers, there is a height deviation when connecting two adjacent pipes, which increases the difficulty and work intensity of pipe connection.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-6 This application is described in further detail.

[0032] The present application embodiment discloses a foundation pit support device for water pipeline construction. Figure 1 and Figure 2 The foundation pit support device includes a support plate 1 and a support rod 2. The support plate 1 is symmetrically installed on the inner wall of the foundation pit and arranged in an array along the length direction of the foundation pit. Adjacent support plates 1 are abutted against each other. The support plate 1 includes a vertical plate 101 and a horizontal plate 102. The vertical plate 101 and the horizontal plate 102 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 anchors, ground nails, etc.

[0033] The support rod 2 is symmetrically arranged between the two support plates 1, and the support rod 2 is horizontally arranged and connected between the two opposite vertical plates 101, so as to further support 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 with a mounting cylinder 18, and the mounting cylinder 18 is threadedly connected to the connecting seat 19, so that the two ends of the support rod 2 support the vertical plate 101. Furthermore, the thread directions between the mounting cylinder 18 and the connecting seat 19 at both ends of the support rod 2 are opposite, so that the support rod 2 is not easy 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, corresponding to being located directly below the pipeline. The support member 3 includes a connecting tube 31 sleeved on the outer wall of the support rod 2, an extension rod 32 fixed on the outer walls of both ends of the connecting tube 31, and an adjustment tube 33 threadedly connected to the outer wall of the extension rod 32. The support rod 2 is a cylindrical structure, and the connecting tube 31 is a cylindrical structure. The connecting tube 31 is sleeved on the outer wall of the support rod 2, so that the connecting tube 31 can rotate or slide. The two extension rods 32 extend along the radial direction of the connecting tube 31 and are parallel to each other. By rotating the adjusting tube 33, the distance between the end of the adjusting tube 33 and the surface of the connecting tube 31 can be adjusted.

[0035] The connecting tube 31 can have two states. When the connecting tube 31 rotates to the state where the extension rod 32 is vertically downward, the end of the adjusting tube 33 is adjusted to abut against the bottom surface of the foundation pit, so that the extension rod 32 can support the supporting rod 2. The connecting tube 31 rotates to the state where the extension rod 32 is vertically upward, so that the two extension rods 32 can support the pipeline, and the adjusting tube 33 can be adjusted to adjust the support height of the pipeline, so as to facilitate the alignment and connection of the pipeline. A limiting member 4 is provided between the connecting tube 31 and the supporting rod 2. When the connecting tube 31 rotates, the connecting tube 31 is positioned by the limiting member 4, so that the connecting tube 31 is not easy to rotate again.

[0036] Combination Figure 4 and Figure 5 The limiting member 4 includes a limiting block 41 fixed on the outer wall of the support rod 2, and the limiting block 41 is symmetrically arranged on the outer wall of the support rod 2. The inner wall of the connecting tube 31 is provided with a limiting groove 5, and the limiting groove 5 extends along the axial direction of the connecting tube 31. The limiting groove 5 and the limiting block 41 correspond one to one, and the limiting block 41 extends in the limiting groove 5. When the connecting tube 31 slides on the support rod 2, the limiting block 41 slides relatively in the limiting groove 5, and under the action of the limiting block 41 and the limiting groove 5, the connecting tube 31 cannot rotate on the support rod 2. An annular groove 6 is provided on the inner wall of the connecting tube 31, and the annular groove 6 extends along the circumference of the connecting tube 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 tube 31 can rotate.

[0037] Furthermore, an elastic member 7 is installed between the support rod 2 and the connecting tube 31, and the elastic member 7 is used to drive the limit block 41 to abut against the inner wall of the limit groove 5 at one end away from the annular groove 6. When the connecting tube 31 needs to be rotated, the connecting tube 31 is slid so that the limit block 41 enters the annular groove 6, and the elastic member 7 is in a compressed state at this time.

[0038] Reference Figure 3-5, an annular protrusion 8 is coaxially fixed on the outer wall of the support rod 2, and the elastic member 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 tube 31. When the connecting tube 31 slides in the direction close to the annular protrusion 8, the limit block 41 can enter the annular groove 6, and the spring is compressed. Under the action of the spring, the limit block 41 can abut against the inner wall of the end of the limit block 41 away from the annular groove 6, the limit block 41 can limit the rotation of the connecting tube 31, and the limit block 41 is not easy to detach from the limit groove 5. In order to improve the stability of the connecting tube 31, two groups of limit members 4 are provided, and are respectively located at the two ends of the connecting tube 31.

[0039] Further, combined with Figure 6 The outer wall fixing rod of the support rod 2 has a support rod 9, which extends vertically downward. The end of the support rod 9 away from the support rod 2 is threadedly connected with a support sleeve 20, and the support sleeve 20 can be made to abut against the bottom surface of the foundation pit by rotating the support sleeve 20. A receiving groove 10 is provided on the outer wall of the connecting tube 31, and the receiving groove 10 extends along the axial direction of the connecting tube 31, and the support rod 9 passes through the receiving groove 10. A clearance groove 11 is provided on the outer wall of the connecting tube 31, and the clearance groove 11 extends along the circumferential direction of the connecting tube 31. When the connecting tube 31 slides, the support rod 9 can enter the clearance groove 11 from the receiving groove 10, and when the connecting tube 31 rotates, the support rod 9 can move relatively in the clearance groove 11. Under the action of the support rod 9, the stability of the support rod 2 when supporting the pipeline is improved. Further, in order to improve the effect of supporting the pipeline, the end of the adjusting tube 33 away from the extension rod 32 is ball-hinged with a contact plate 12, thereby increasing the contact area between the adjusting tube 33 and the pipeline.

[0040] Reference Figure 4 and Figure 5 The extension rod 32 is welded to the outer wall of the connecting tube 31, and the extension rod 32 is an internal hollow structure. A through hole 14 is provided at a position of the connecting tube 31 corresponding to the inner cavity of the extension rod 32. A reinforcement rod 13 is slidably installed in the extension rod 32, and one end of the reinforcement rod 13 slides through the through hole 14. A plug-in slot 15 for inserting the end of the reinforcement rod 13 is provided on the outer wall of the support rod 2. When the connecting tube 31 is rotated to the extension rod 32 vertically upward, the reinforcement rod 13 can be inserted into the plug-in slot 15, and a driving member 16 for driving the end of the reinforcement rod 13 to abut against the plug-in slot 15 is installed in the extension rod 32. The driving member 16 is preferably a spring.

[0041] The bottom surface of the plug slot 15 is inclined upward toward the direction close to the annular protrusion 8. When the connecting tube 31 moves toward the direction close to the annular protrusion 8, the end of the reinforcing rod 13 moves uphill in the plug slot 15 and gradually slides out of the plug slot 15, so that the reinforcing rod 13 does not affect the rotation of the connecting tube 31. Under the action of the reinforcing rod 13, the extension rod 32, the connecting tube 31 and the supporting 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 the embodiment of the present application is: under the action of the support rod 2, the support effect of the support plate 1 is improved. When the adjustment cylinder 33 abuts against the bottom surface of the foundation pit, the stability of the support rod 2 can be improved. When the pipeline needs to be adjusted and supported in the height direction during pipeline connection, the connection cylinder 31 rotates until the extension rod 32 is vertically upward, and the two adjustment cylinders 33 can support the pipeline.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
