Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline construction technical field especially relates to a municipal road drainage pipeline optimization device. BACKGROUND

[0002] The municipal road drainage includes road surface drainage part and road side drainage part, and the road surface drainage part is sequentially from below to above: base layer, waterproof layer, water permeable layer, and the waterproof layer top is equipped with road surface drainage groove; The road side drainage part includes road side drainage groove and drainage well on both sides of the road; In the pipeline construction process, when the pipeline is laid, cement mortar banding treatment needs to be carried out at the inner and outer interfaces of the pipeline, so that the adjacent pipelines are connected firmly, and the pipelines are prevented from seeping, sinking and other conditions during use.

[0003] The patent with the publication number CN214657579U discloses a municipal road drainage pipeline optimization device, when in use, the staff presses the fixed shaft, the fixed shaft is separated from the fixed hole, the pipe piece one is pulled, the length of the movable pipe is adjusted according to the length of the pipeline, the fixed shaft is clamped with the fixed hole under the spring elastic force, the pipe piece two is fixedly connected with the pipe piece one, the rod piece one is pulled, the screw rod slides on the sliding groove, the length of the fixed rod is adjusted, the fixed nut is rotated, the gasket is attached to the rod piece one, the rod piece one is fixedly connected with the rod piece two, the cement mortar is applied on the plasterboard, the fixed rod is moved, the fixed frame slides in the pipeline, the plasterboard is driven to the pipeline interface, the movable pipe is pushed, the fixed ring drives the connecting plate to move left, the adjusting plate rotates on the movable ring, the adjusting assembly is opened, the plasterboard is attached to the inner wall of the pipeline, the movable pipe is rotated by rotating the swing rod, the plasterboard is rotated by the adjusting assembly, the plasterboard applies cement to the structure of the inner wall of the pipeline, and the cement is smoothed when the plasterboard rotates circularly. However, the above-mentioned device has the following defects when in use. When the device is used for pipeline internal banding construction, cement mortar needs to be applied on the plasterboard first, and then the device is pushed to the interface in the pipeline by the fixed rod and the fixed frame. However, in the process of moving the device to the pipeline interface, the inside of the pipeline is not completely flat, and the device will vibrate and shake when moving. At the same time, the installation mode of the plasterboard on the device makes the cement mortar adhere to the plasterboard only by its own adhesion, and lacks effective fixing measures. This leads to the cement applied on the plasterboard to easily fall in the way. Once the cement falls, the amount of cement on the plasterboard is often insufficient to complete the application work at the interface. At this time, the staff can only pull the device out of the pipeline, reapply cement on the plasterboard, and then push the device to the pipeline interface again. This not only increases the construction time and labor intensity, but also reduces the construction efficiency.

[0004] Therefore, how to avoid cement from falling during transportation to the construction position becomes a technical problem that technicians in the field need to solve. Utility model content
