Description

Technical Field

[0001] The utility model relates to the technical field of construction safety, in particular to a deep excavation supporting device for underground pipelines. Background Art

[0002] In civil engineering, underground excavation, drilling and grouting, piling support, pipe jacking, pipe pulling and other constructions must be carried out in advance through on-site disclosure and detection of underground pipelines to find out the location, direction, burial depth, integrity, etc. of underground pipelines including water supply, drainage, gas, heat, telecommunications, national defense optical cables, electricity, industry and comprehensive pipelines. However, some underground pipelines must be manually excavated to timely and safely find all underground facilities that affect underground construction due to "long construction years, unclear positioning records, insufficient detection accuracy, or need to be dug out, relocated or protected" to avoid affecting the construction safety and progress of related projects.

[0003] At present, when deep excavation of underground pipelines is carried out, only simple fencing is built around the inner wall of the foundation pit, resulting in general construction safety. In addition, as the excavation depth increases, it is not convenient to install a secondary fence. Based on this, we propose an underground pipeline deep excavation support device for improvement.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, an underground pipeline deep excavation support device includes a enclosure 1, a ladder 2, a mounting column 9 and a top plate 12. A plurality of hanging plates 8 are fixedly connected to the outer wall of the enclosure 1, a plurality of locking plates 10 are rotatably connected to the outer wall of the mounting column 9, and the locking plates 10 are movably sleeved on the hanging plates 8. Screw holes 4 are provided on the upper end of the enclosure 1 near both sides, and positioning screws 5 are sleeved on the inner threads of the screw holes 4. A mounting block 11 is fixedly connected to the upper end of the mounting column 9, and a mounting groove 13 is provided at the lower end of the mounting column 9. An inlet and outlet 15 is provided on one side of the upper end of the top plate 12, and a trap door 16 is rotatably provided on the inlet and outlet 15. A pipe hole 3 is provided at the lower end of the middle part of the enclosure 1, and the pipe hole 3 is used to be erected above the pipeline.

[0024] In this embodiment, the entrance and exit 15 is arranged at a position directly above the ladder 2 , and a handle is fixedly connected to the trap door 16 to facilitate opening the trap door 16 from the upper end of the top plate 12 .

[0025] As a further solution of the utility model, the height of the positioning screw 5 is greater than the height of the enclosure 1, and the lower end is made of a conical structure, which is convenient for anchoring the positioning screw 5 into the soil layer to reinforce the enclosure 1.

[0026] As a further solution of the utility model, a knob 6 is fixedly connected to the upper end of the positioning screw 5, a receiving groove 7 is opened at the lower end of the enclosure 1, and a receiving groove 2 14 is opened at the lower end of the top plate 12. The receiving groove 1 7 and the receiving groove 2 14 are the same size, and the receiving groove 1 7 and the receiving groove 2 14 are matched with the knob 6. The receiving groove 1 7 is sleeved with the knob 6 so that there is no large gap between the upper and lower adjacent enclosures 1 when there are multiple layers of enclosures. The receiving groove 2 14 is sleeved with the knob 6 so that there is no large gap between the top plate 12 and the enclosure 1 when only a single-layer enclosure is equipped with the top plate 12.

[0027] As a further solution of the utility model, a docking groove 17 is provided on the lower end surface of the top plate 12, the mounting groove 13 and the docking groove 17 are of the same size, and the mounting groove 13 and the docking groove 17 are matched with the mounting block 11. The upper and lower mounting columns 9 can be docked by using the mounting block 11 to fit the mounting groove 13, and the top plate 12 can be installed on the upper end of the enclosure by using the mounting block 11 to fit the docking groove 17.

[0028] As a further solution of the utility model, four enclosures 1 and mounting columns 9 are provided, and the ladder 2 is fixedly connected to the inner wall of one of the enclosures 1. When the enclosure is provided with multiple layers, multiple ladders 2 are connected to each other to facilitate workers to enter and exit.

[0029] As a further solution of the utility model, multiple hanging plates 8 and locking plates 10 are provided, and multiple hanging plates 8 are evenly distributed on the outer wall of the enclosure 1, and multiple locking plates 10 are evenly distributed on the outer wall of the mounting column 9. The installation can be completed by rotating the locking plate 10 to engage it on the hanging plate 8. Then, the characteristic that the locking plate 10 is distributed on two vertical planes of the mounting column 9 can be used to prevent the enclosure 1 from sliding in the horizontal direction, which is convenient and saves trouble.

[0030] It should be noted that the utility model is a deep excavation support device for underground pipelines. When in use, the enclosure 1 with the ladder 2 is threadedly sleeved into the screw hole 4 through the positioning screw 5, and then rotated until the lower end of the positioning screw 5 extends out of the enclosure 1 and enters the soil layer to fix the enclosure 1, and then the locking plate 10 is sleeved with the hanging plate 8 to install the other three enclosures 1 and four installation columns 9 to form an enclosure. At the same time, the positioning screw 5 is used to fix the remaining three enclosures 1 so that the enclosure can be stabilized on the ground. Then, according to the depth of the foundation pit, when the enclosure needs to be raised, only the locking plate 10 is used to sleeve the hanging plate 8 to install the other three enclosures 1 and four installation columns 9 to form an enclosure. It is necessary to connect the mounting grooves 13 at the lower ends of the four mounting columns 9 with the mounting blocks 11 at the upper ends of the four mounting columns 9 that have been installed in turn, and then install the four enclosure panels 1 to complete the construction of double-layer or even multi-layer enclosures. Then, the end of the top plate 12 with the inlet and outlet 15 is installed toward the position of the ladder 2, and the top plate 12 can be fixed by using the topmost mounting block 11 to fit the docking groove 17, so that the support device can not only adapt to foundation pit support of different depths, but also be convenient and quick to disassemble and replace, thereby improving the construction effect.
