Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Embodiment 1

[0030] As Figures 1 to 3 shown, a municipal engineering pipeline construction interception device, including vertical first support 1, first support 1 includes the screw sleeve 11 of upper opening, the screw sleeve 11 is screw threaded with screw rod 12, the top of screw rod 12 is fixedly provided with first conical head 13, the bottom surface of screw sleeve 11 is fixedly provided with second conical head 14. The upper end side of screw sleeve 11 of first support 1 is provided with vertical fixed plate 2, the center position of fixed plate 2 is provided with through hole 21, the second support 3 is slidably arranged in through hole 21 in the transverse direction, and the structure of the second support 3 is same with the structure of the first support 1 (the difference is that the side of the screw sleeve 11 of the second support 3 is not provided with the fixed plate 2).

[0031] The screw rod 12 below the first conical head 13 is provided with the first perforation 121 in the transverse direction, and the first pin shaft 4 is slidably arranged in the first perforation 121.

[0032] The first pin shaft 4 includes the plug 41 in the transverse direction, and the cylindrical limit block 42 is fixedly arranged at one end of the plug 41.

[0033] The screw sleeve 11 above the second conical head 14 is provided with the second perforation 111 in the transverse direction, and the second pin shaft 5 is slidably arranged in the second perforation 111, and the structure of the second pin shaft 5 is same with the structure of the first pin shaft 4.

[0034] The length of screw 12 is greater than the length of screw sleeve 11.

[0035] Screw insert 11 is a stainless steel screw insert, and screw 12 is a stainless steel screw.

[0036] The outer surface of the first pin 4 is provided with a rubber layer (not shown in the figure), and the rubber layer is in damping sliding fit with the first through hole 121.

[0037] The outer surface of the insert of the second pin 5 is provided with a rubber layer (not shown in the figure), and the rubber layer is in damping sliding fit with the second through hole 111.

[0038] In use, the first support 1 and the second support 3 are respectively brought into the maintenance point inside the pipeline. First, the first support 1 is placed vertically so that the second conical head 14 abuts against the inner bottom surface of the pipeline 6. Then, the screw 12 is rotated to extend the screw 12, so that the first conical head 13 at the top abuts against the inner top surface of the pipeline 6, thus vertically supporting and fixing the first support 1. Then, the second support 3 is passed horizontally through the through hole 21 on the fixing plate 2, so that the second conical head 14 of the second support 3 abuts against the left side of the pipeline 6. Then, the screw 12 is tightened so that the first conical head 13 abuts against the right side of the pipeline 6, thus horizontally supporting and fixing the second support 3. The whole device can block and intercept maintenance personnel. The pointed (conical head) structure is not easy to slip, and the overall structure is simplified, which helps to reduce production costs. The first pin 4 and the second pin 5 make it convenient for workers to hold and tighten the screw 12 or the screw sleeve 11, allowing the device to be disassembled and assembled without a wrench. Example 2

[0039] like Figure 4 As shown, rubber bolts 7 that limit the movement of the screw rod 12 are also screwed inward on one side of the upper end of the screw sleeve 11.

[0040] In use, after adjusting the positions of the first support 1 and the second support 3, the rubber bolt 7 can be screwed inward so that the inner end of the rubber bolt 7 abuts against the screw rod 12, preventing loosening and support failure. The rubber bolt 7 also protects the threads of the screw rod 12. Example 3

[0041] like Figure 5 As shown, the screw sleeves 11 of the first support member 1 and the second support member 3 are respectively fixed with arc-shaped handles 8.

In addition, after the first support 1 and the second support 3 are disassembled, the screw 12 is retracted into the screw sleeve 11 as much as possible. The curved handle 8 makes it easy for staff to carry, and facilitates handling and carrying.
