Description

Technical Field

[0001] The present invention relates to the technical field of municipal pipeline construction engineering, and more particularly to a high-efficiency underground pipeline burial construction system and a construction method thereof. Background Art

[0002] When laying underground pipelines in municipal engineering construction, a deep trench for burying the pipelines must first be excavated on the ground. To prevent the deep trench walls from collapsing while workers are working in the deep trench (such as connecting adjacent pipelines, installing three-way valves on pipelines, and conducting water-tightness tests), which could lead to safety accidents and affect the standardization of pipeline installation depths, existing technologies typically install steel guard plate support structures within the excavated deep trench to support the trench walls and prevent them from collapsing.

[0003] This existing support method has a good protective effect. However, the installation and removal of the steel guard plate are relatively cumbersome, and the installation and removal of the steel guard plate will slow down the overall underground pipeline burial work, making the construction process of this support and pipeline burial seem backward. Summary of the Invention

[0004] In response to the technical problem of low efficiency in underground pipeline burial in the existing technology raised in the background technology, the present invention sets a trench support unit to be installed in the deep trench after excavation, and uses a traction unit to move the support position of the trench support unit, which is circulated to the specific position of underground pipeline burial, with high work efficiency.

[0005] The present invention provides the following technical solution 1:

[0006] An efficient underground pipeline construction system, the construction system consists of the following two parts:

[0007] A trench support unit, the trench protection unit includes a left supporting side plate, a right supporting side plate and a bottom support plate; a traction unit, the traction unit is connected to the trench support unit, the traction unit is used to pull the trench support unit forward in the excavation direction in the deep trench, the lower surface of the bottom support plate is close to the bottom surface of the trench, and the upper surface of the bottom support plate is provided with a rotating component.

[0008] Through the above technical solution, the present invention sets a trench support unit to be installed in the deep trench after excavation, and uses a traction unit to move the support position of the trench support unit, which is circulated to the specific location of the underground pipeline burial, with high work efficiency.

[0009] The present invention further: a rotating drum is rotatably installed between the left supporting side plate and the right supporting side plate, and the rotating drum is the rotating assembly, and the rotating drum is used for the underground pipeline to slide on its upper surface.

[0013] Through the above technical solution, the left shallow area support plate and the right shallow area support plate are used to be installed in the shallow area of ​​the deep groove. The groove width of the shallow area is generally wider than that of the deep area. Therefore, the left shallow area support plate and the right shallow area support plate are arranged at an angle to allow the left shallow area support plate and the right shallow area support plate to be close to the groove wall.

[0014] The present invention further provides that: the upper parts of the left shallow area support plate and the right shallow area support plate are both installed with steel wire guardrails, and the steel wire guardrails are located above the ground.

[0015] Through the above technical solution, the steel wire guardrail is used to be installed in the ground area of ​​the deep trench.

DETAILED DESCRIPTION

[0040] The present invention will be further described in detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0041] An efficient underground pipeline construction system, combined with Figure 1 As shown, the construction system consists of two parts: a trench support unit 100 and a traction unit 200. Its working principle is as follows: First, the trench support unit 100 is installed in the excavated trench as a protective device for installing underground pipelines. The underground pipeline to be buried is prevented from being buried in the trench support unit 100, and installation work such as pipeline connection is carried out. During pipeline installation, the trench can continue to be excavated along its length. After the pipeline is installed, the traction unit 200 provides traction to drive the trench support unit 100 to slide in the trench. The installed pipeline remains in place and is located at the bottom of the trench. A new underground pipeline is then placed in the trench support unit 100 and connected to the previous underground pipeline to form a whole, thereby advancing in the direction of trench excavation. While advancing, the location of the installed underground pipeline can be subjected to a water-tightness test or a pipeline well can be installed. The water-tightness test refers to the test of the water-tightness performance of the pipeline connection. When all these tasks are completed, the location of the installed underground pipeline is backfilled. The underground pipeline burial construction system of the present invention is simple to operate and highly efficient, and has excellent practical effects. The specific structural design is as follows:

[0042] Combine Figure 2As shown, the trench support unit 100 of the present invention comprises three parts from bottom to top: a deep area protection structure, a shallow area protection structure, and an above-ground protection structure. The deep area protection structure refers to the left supporting side plate 101, the right supporting side plate 102, and the bottom support plate 103; the shallow area protection structure refers to the left shallow area support plate 104 and the right shallow area support plate 105; and the above-ground protection structure refers to the wire guardrail 106. The following describes each of them one by one:

[0043] Regarding the deep zone protection structure, the trench protection unit 100 includes a left supporting side plate 101, a right supporting side plate 102, and a bottom support plate 103. The left supporting side plate 101, the right supporting side plate 102, and the bottom support plate 103 are made of welded steel plates and have an overall U-shaped shape. The purpose is to protect the narrower area of ​​the trench depth zone and serve as the main working area for pipeline installation. To facilitate the rolling of the pipeline within the trench protection unit 100, a rotating drum 300 is rotatably installed between the left supporting side plate 101 and the right supporting side plate 102 of the present invention. The rotating drum 300 is used for the underground pipeline to slide on its upper surface. The axial direction of the rotating drum 300 is perpendicular to the left supporting side plate 101 and the right supporting side plate 102.

[0044] Regarding the shallow area protection structure, the trench support unit 100 includes a left shallow area support plate 104 and a right shallow area support plate 105. The left shallow area support plate 104 is fixed to the top of the left support side plate 101, and the right shallow area support plate 105 is fixed to the top of the right support side plate 102. Because the width of the shallow area trench is generally wider than the trench bottom, the left shallow area support plate 104 and the right shallow area support plate 105 are not parallel to each other, but are in an upwardly flared shape to better fit the inner wall of the shallow area of ​​the trench and provide better support.

[0045] Regarding the above-ground protective structure, a steel wire guardrail 106 is installed above the left and right shallow area support plates 104 and 105. Steel wire guardrail 106 is located above the ground. Since construction is ongoing within the trench, installing steel wire guardrail 106 above ground serves as a reminder to above-ground workers to avoid falling into the trench, and also ensures the safety of those working underground.

[0046] The traction unit 200 of the present invention is connected to the trench support unit 100 and is used to pull the trench support unit 100 forward in the excavation direction within the deep trench. The traction unit 200 can be replaced by an excavator at the trench excavation site to drive the trench support unit 100 forward.

[0047] Based on the above high-efficiency pipeline underground burial construction system, the present invention provides a high-efficiency pipeline underground burial construction method, combined with Figure 3 As shown, the following steps are included:

[0048] Step 1: Construction preparation;

[0049] Step 2: Trench excavation: excavate the trench according to the underground pipeline laying project plan;

[0050] Step 3: Place the finished trench support unit: Place the trench support unit in the excavated trench;

[0051] Step 4: Pipeline laying;

[0052] Step 4-1: Move the pipe to be laid and place it on top of the rotating drum;

[0053] Step 4-2: Perform related operations on the pipe above the drum;

[0054] Step 5: Use the traction unit to pull the trench support unit in the excavation direction, driving the trench support unit to slide along the trench excavation direction in the trench. At the same time, the laid pipeline remains in place.

[0055] Step 6: You can choose to limit and fix the backfill soil on the bottom surface, left and right sides, and top surface of the laid pipeline;

[0056] Step 7: Repeat Step 4, Step 5 and Step 6 in a loop;

[0057] At the same time, you can choose to excavate continuously along the excavation direction of the trench simultaneously;

[0058] Step 8: After all the pipes in the trench are laid, remove the trench support unit from the trench, backfill the trench with all the soil and tamp it.

[0059] The "placement of finished trench support units" in Step 3 can also be done by welding the trench support units in the trench.

[0060] "Performing related operations on the pipes above the drum" in Step 4-2 refers to connecting adjacent pipes and installing water valves on the pipes.

[0061] Between Step 7 and Step 8, that is, after the pipeline is laid and before all the earth is backfilled, the pipeline well construction step and the water-tightness test step can also be carried out.

[0062] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
