Description

Technical Field

[0001] The utility model relates to a pipeline opening blocking construction structure, belonging to the technical field of construction. Background Art

[0002] During the construction of a power station, it is necessary to bury pipes in the construction site for laying cables, etc. When the pipes are buried over a long distance, they cannot be laid all at once, resulting in temporary leakage from the pipe openings. In order to prevent foreign objects such as stones or soil from entering the open pipe openings at the construction site, the pipe openings need to be sealed.

[0003] Existing pipe opening blocking technologies, such as a pipe opening blocking device for pre-buried water and electricity pipes in buildings with Chinese patent publication number CN213268391U, use a connecting rod to push the rubber pad at the end of the stabilizing plate against the inner wall of the pre-buried pipe opening, so that the blocking device is installed with the pipe as the force-bearing basis. Although the blocking device as a whole can block the pipe opening in the pipe, for pre-buried and suspended pipes with a long length, the increased weight of the blocking device on the pipe will pull down the suspended pipe and cause deformation. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a pipeline opening blocking construction structure.

[0005] The utility model is achieved through the following technical solutions.

[0006] The utility model provides a pipeline opening blocking construction structure, comprising:

[0007] The bottom rock and soil layer with trenches;

[0008] The pipe mouth of the pipe extends and is suspended in the space of the bottom rock and soil layer; there is a backfill layer on the bottom rock and soil layer, and the backfill layer is pressed on the upper part of the pipe;

[0009] The blocking plate is supported from the outside and is in an upright position to block the pipe opening.

[0010] The blocking plate is supported from the outside by the first external force component and / or the second external force component and is in an upright state to block the pipe opening.

[0011] A crushed stone layer is laid in the groove of the bottom rock layer, the pipeline is located in the crushed stone layer, the backfill layer is pressed on the crushed stone layer in the upper part of the pipeline, and the crushed stone layer wraps around the pipeline to provide a rigid surrounding layer.

[0012] The first external force component includes an oblique support and a support block.

[0013] The inclined support is installed at an angle, and the top end of the inclined support is supported on the middle part of the back side of the sealing plate away from the pipeline, and the bottom end of the inclined support is supported by a support block installed in the gravel layer. The support block is installed on the gravel layer to support the bottom part of the back side of the sealing plate away from the pipeline, so that the sealing plate obtains force support from the outside and is upright and close to the pipeline orifice for sealing.

[0014] The oblique support is formed by a telescopic rod.

[0015] The second external force component includes a tension rod and a knotted rope.

[0016] The tension rods are knocked into the backfill layer. There are two tension rods distributed on both sides of the sealing plate. The tension rods are tied to the upper and lower backs of the two sides of the sealing plate through two tie ropes distributed at oblique angles, so that the sealing plate can obtain force support from the outside and be upright and close to the pipe mouth for sealing.

[0017] The beneficial effect of the utility model is that the blocking plate obtains force support from the outside to block the pipe mouth, so that the suspended pipe will not be pulled down and deformed by other loads, solving the problem that the blocking device as a whole is on the pipe and the increased weight will pull down the suspended pipe and cause deformation.

[0022] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0023] like Figures 1 to 2 shown.

[0024] A pipeline opening blocking construction structure of the present application includes:

[0025] A bottom rock layer 1 is provided to bear the bottom force. The bottom rock layer 1 is provided with a trench 11 for burying a pipeline 3. A crushed stone layer 2 is laid in the trench 11 of the bottom rock layer 1. The pipeline 3 is located in the crushed stone layer 2. The crushed stone layer 2 wraps around the pipeline 3 to provide a rigid surrounding layer. The pipe opening of the pipeline 3 extends and is suspended in the space of the bottom rock layer 1.

[0026] The device also includes a blocking plate 4, constructed from a board such as a wooden board, which abuts the end of the pipe 3. An inclined support 5 is installed at an angle on the back of the blocking plate 4, away from the pipe 3. The top of the inclined support 5 contacts the middle of the back of the blocking plate 4, and the bottom of the inclined support 5 is supported by an abutment 6 installed in the gravel layer 2. The inclined support 5 is constructed using a retractable telescopic rod.

[0027] It also includes a support block 7 made of stones, which is installed on the gravel layer 2 to support the bottom back of the blocking plate 4 away from the pipeline 3, ensuring that the blocking plate 4 is upright and close to the pipe mouth of the pipeline 3 for blocking.

[0028] The gravel layer 2 in the upper part of the pipe 3 is backfilled with a backfill layer 8. The backfill layer 8 is composed of soil and stone. The backfill layer 8 is pressed on the gravel layer 2 in the upper part of the pipe 3. When there is no gravel layer 2, the backfill layer 8 is pressed on the upper part of the pipe 3. A tension rod 9 is knocked and inserted into the backfill layer 8. The tension rod 9 corresponds to the upper and lower positions of the back of the sealing plate 4 through two tie ropes 10 distributed at oblique angles. When there are inclined supports 5 and support blocks 7, the installation of the tension rod 9 and the tie rope 10 plays a reinforcing role. The inclined supports 5 and support blocks 7 can be installed and function separately, and the tension rod 9 and the tie rope 10 can also be installed and function separately. The inclined supports 5 and support blocks 7 and the tension rod 9 and the tie rope 10 can be installed and function at the same time.

[0029] The pipe mouth of the pipe 3 extending and suspended in the bottom rock and soil layer 1 is blocked by the sealing plate 4. The inclined support 5 and the support block 7 constitute the first external force component to support the sealing plate 4 from the outside of the pipe 3. At the same time, the tension rod 9 and the tie rope 10 constitute the second external force component to support the sealing plate 4 from the outside of the pipe 3. Since the sealing plate 4 obtains force support from the outside to block the pipe mouth of the pipe 3, the suspended pipe 3 will not be pulled down by other loads to deform itself, which solves the problem that the sealing device as a whole is on the pipe, which causes the increased weight to pull down the suspended pipe and cause deformation.

[0030] A pipeline burial construction method of the present application includes:

[0031] Step 1: Laying: A trench 11 is excavated on the bottom rock and soil layer 1. The lower half of the gravel layer 2 is laid in the trench 11, and then the pipeline is laid. At this time, the lower half of the gravel layer 2 is laid with an inclined portion from the end of the trench 11. The upper half of the gravel layer 2 is laid, so that the gravel layer 2 composed of gravel wraps around the pipeline 3 to provide a rigid surrounding layer. At this time, the pipe mouth of the pipeline 3 extends and is suspended in the space of the bottom rock and soil layer 1;

[0032] Step 2: Blocking: The blocking plate 4 is pressed against the pipe opening of the pipe 3, and the back side of the blocking plate 4 is erected close to the pipe opening of the pipe 3 by the first external force component and / or the second external force component to block the blocking plate 4.

[0033] The upright blocking plate 4 is pressed against the pipe mouth of the blocked pipe 3 through the first external force component and / or the second external force component, so that the pipe 3 extending and suspended in the space of the bottom rock and soil layer 1 will not be pulled down and deformed by other loads, thereby solving the problem that the blocking device as a whole is on the pipe, which causes the increased weight to pull down the suspended pipe and cause deformation.
