Description

Technical Field

[0001] The present invention relates to the technical field of pipeline laying, in particular to a vertical excavation and support process for a soft soil pipe trench and a pipeline laying device. Background Art

[0002] During the pipeline laying process, corresponding support equipment is needed to support the trench where the pipeline is laid to prevent the trench from deforming or becoming unstable when construction workers are laying the pipeline.

[0003] Although existing support equipment can support the excavated trench, during the installation process, most of the support equipment is directly pressed and fixed inside the trench by excavators and other equipment. Although this installation method can fix the support equipment inside the trench, when multiple support equipment needs to be installed inside the trench, the adjacent support equipment will often be pushed by the subsequently installed support equipment, causing the support equipment previously installed inside the trench to shift. At this time, the shifted support equipment will affect the subsequent pipeline laying. For this reason, we proposed a vertical excavation support process and pipeline laying device for soft soil trenches. Summary of the Invention

[0004] In order to solve the technical problem of poor stability of existing pipeline laying devices, the present invention provides a vertical excavation and support process for a soft soil trench and a pipeline laying device.

The inner wall of the trench can be supported by the support plate. The bolt 1 is rotated to drive the bolt 1 to move vertically. When the bolt 1 is disengaged from the inside of the threaded groove 1, the support plate can be pulled. The sliding cooperation between the mounting groove and the support block can drive the support block and the support plate to move. At this time, the spacing between the two support plates can be adjusted according to the width of the trench. The bolt 2 is rotated to drive the bolt 2 to move. When the bolt 2 is disengaged from the inside of the threaded groove 2, the support block can be pulled to drive the support block and the fixing plate to move. When the fixing plate is separated from the support plate, the two support plates are split.

[0006] The top of described supporting plate is hinged on the base, and the supporting plate is hinged on the base, and the supporting plate is hinged on the base. A second sliding groove is provided, and a card block is inserted into the sliding interior of the second sliding groove, and the mounting block is provided with a card slot that slides with the card block. A baffle is provided between the two support plates, and a placement groove is provided on the side of the card block close to the baffle. The two ends of the baffle slide in the adjacent placement grooves respectively.

The corresponding heights of the linkage plate and the stabilizing bar can be adjusted according to the corresponding heights of the soil on both sides of the trench. The corresponding position of the stabilizing bar can be adjusted to avoid stones in the soil on both sides of the trench blocking the stabilizing bar from being inserted into the soil. The baffle can be used to protect the construction personnel inside the trench.

[0007] As a further improvement of the above scheme, sliding grooves are opened on the inner walls on both sides of the slide groove, and a sliding block sliding inside the sliding groove is fixed on the outer side of the stabilizing rod. The stabilizing rod inside the slide groove can be limited by the sliding cooperation between the sliding groove and the sliding block.
