Description

Technical Field

[0001] The utility model relates to the technical field of anti-deformation devices, in particular to an anti-deformation device for a steel corrugated culvert pipe. Background Art

[0002] The steel corrugated culvert pipe is a pipe structure widely used in transportation and water conservancy projects, mainly used in culverts, drainage, tunnels and other occasions. Its unique corrugated shape endows it with superior strength and flexibility, enabling it to withstand pressures under different soil conditions. The material of the steel corrugated culvert pipe is usually made of high-quality carbon steel, which has a long service life after anti-corrosion treatment. Today, with the increasing emphasis on environmental protection, the application of steel corrugated culvert pipes also reflects the concept of sustainable development. Its good drainage performance can effectively avoid rainwater accumulation and reduce the risk of water pollution, and also promotes the protection of the ecological environment to a certain extent.

[0003] When some existing steel corrugated culvert pipes are in use, most of them are directly placed in the drainage trough and then covered with soil. Because they are directly placed in the drainage trough, when encountering situations such as vehicle passage, soil settlement and environmental changes, the steel corrugated pipes will bear different degrees of pressure and tension, so the steel corrugated pipes are prone to structural deformation or even rupture, thus affecting their drainage effect and traffic function. Therefore, this problem needs to be solved. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose an anti-deformation device for a steel corrugated culvert pipe.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An anti-deformation device for a steel corrugated culvert pipe, including a housing. Bolts are fixedly connected to the four corners of the housing. Support plates are sleeved at both ends of the four bolts. The two support plates cooperate with the housing. A storage groove is opened at the top of the housing. A top plate is slidably connected inside the storage groove. A reset mechanism for resetting the top plate is provided at the bottom of the top plate. A same corrugated pipe is provided inside the two support plates and the housing. A plurality of support rings are provided on the inner surface of the housing. The plurality of support rings cooperate with the corrugated pipe. Support mechanisms for supporting the support rings are provided at the bottoms of the plurality of support rings. Two support plates are symmetrically and slidably connected to the inner surface of the housing near the support rings. Moving mechanisms for moving the support plates are provided on the surfaces of the two support plates away from the support rings. Through the setting of the housing, the phenomenon of deformation and rupture of the corrugated pipe can be reduced.

[0007] As a further solution of the utility model, the reset mechanism includes multiple limit rods, multiple limit rods are fixedly connected to the bottom of the top plate, and multiple limit rods are slidably connected to the inner surface of the storage groove, a separation ring is fixedly connected to the top of the outer shell close to the storage groove, the separation ring is evenly arranged in a square shape, a docking groove is opened at the bottom of the top plate close to the separation ring, the separation ring is slidably connected to the inside of the docking groove, multiple limit rods are sleeved with a first spring on the surface of the side close to the top plate, multiple bottom ends of the first springs are fixedly connected to the inner surface of the storage groove, and multiple top ends of the first springs are fixedly connected to the bottom of the top plate. The top plate can be reset by setting the first spring.

[0008] As a further solution of the utility model, the supporting mechanism includes two telescopic cylinders, both of which are fixedly connected to the bottom of the support ring, and both of which are fixedly connected to the inner surface of the outer shell. The surfaces of the two telescopic cylinders are sleeved with second springs, the top ends of the two second springs are fixedly connected to the bottom of the support ring, and the bottom ends of the two second springs are fixedly connected to the inner surface of the outer shell. The support ring can be supported by the arrangement of the second springs.

[0009] As a further solution of the utility model, the moving mechanism includes multiple installation grooves, multiple installation grooves are opened on one side of the support plate, multiple installation grooves are slidably connected to one side of the interior of the limit column, and multiple limit columns are fixedly connected to one side of the interior of the shell, multiple limit columns are sleeved with tension springs on the surface, multiple tension springs have one end fixedly connected to one side of the interior of the installation groove, and multiple tension springs have the other end fixedly connected to one side of the interior of the shell, multiple installation grooves cooperate with the support plate, and nuts are installed at both ends of the four bolts. The support plate can be moved by setting the limit column.

[0010] The beneficial effects of the utility model are:

[0011] 1. Since the utility model adopts the technical solution of wrapping the corrugated pipe with the shell, the shell can protect the corrugated pipe to avoid deformation and rupture of the corrugated pipe, thereby effectively solving the problem that when encountering situations such as vehicle passage, soil settlement and environmental changes, the steel corrugated pipe will be subjected to different degrees of pressure and tension, so that the steel corrugated pipe is prone to structural deformation or even rupture, thereby affecting its drainage effect and traffic function. Because the shell wraps the entire corrugated pipe, when the corrugated pipe is in use, the pressure caused by vehicle passage, soil settlement and the like can be reduced, thereby minimizing the deformation and rupture of the corrugated pipe.

[0012] 2. By setting the support plate, the corrugated pipe can withstand a certain external pressure. The support plate is arranged in an inclined shape on the side close to the limit rod. Therefore, when the top plate moves downward due to external pressure, the limit rod will squeeze the support plate, causing it to move forward. After moving forward, the support plate will contact the corrugated pipe, thereby achieving the purpose of supporting the corrugated pipe to prevent the shell from cracking and the corrugated pipe can withstand a certain external pressure.
