In order to more clearly describe the specific implementation of the utility model, an embodiment is provided below:

The utility model is a pipeline suspension protection device for pipe well excavation construction. It has been applied in the protection of 220Kv power pipelines in the pipeline and river relocation at Balitai Station of Metro Line 7 in a certain city, and has been promoted and applied in the subsequent cutting and modification of relevant municipal drainage pipelines. Its construction operation has a simple manufacturing process and can be used repeatedly. It not only plays the role of environmental protection and resource conservation, achieves the effect of green and low carbon, but also ensures that the pipeline can be suspended for protection. It guarantees the molding quality, can be used in a turnover manner, and is easy to disassemble. It not only plays the role of environmental protection and resource conservation, but also reduces costs.

The utility model discloses a pipeline suspension protection device for pipe well excavation construction, and the process flow thereof is: waste material selection→frame erection→placement of angle steel and wooden beams→drilling holes→installation of screw rods and nuts→welding of steel bars.

Compared with the traditional pipeline suspension method, the suspension protection device using the above technical solution has the following advantages in suspending pipelines:

(1) Improve the utilization rate of waste materials: Steel (steel sections or channel steel, etc.), wood beams, and steel bars are commonly used on construction sites, and relatively more waste wood beams, steel bars, and steel are generated. In order to better improve the utilization of waste materials, the site can select suitable waste wood beams, steel bars, and steel for cutting and production to reduce the generation of waste materials.

(2) High turnover rate: It can be manufactured once and used for a long time at the construction site. It is easy to disassemble. This kind of suspension device can not only be used for conversion between the foundation pits of this project, but also can be used for transfer between different projects.

(3) Simple production and convenient operation: Since there are a lot of waste materials on site, the tools are relatively complete, and the production process is relatively simple, it can be processed in batches. During the installation operation, workers can directly reinforce the nuts at both ends to improve the work efficiency of workers.

(4) Less breakage, repair and maintenance: The assembled "mouth" type device has a simple connection method. Since its main components are steel materials such as steel sections or channel steels, steel bars, screws, wooden beams, etc., it is less likely to be damaged. If damage occurs, the device can be repaired immediately and can be used after completion.

(5) Energy saving, environmental protection and resource conservation: By increasing the use of waste materials, the generation of construction waste is reduced, and batch production can be carried out on site, eliminating the environmental pollution caused by the production and processing of traditional suspension devices by upstream industries.

The utility model is a pipeline suspension protection device for pipe well excavation construction. According to the width of the on-site pipeline and the foundation pit excavation, the on-site steel or channel steel and other waste steel materials can be selected and overlapped vertically and horizontally to form a framework, and then angle steel is placed on the upper part of the steel, and then wooden beams and angle steel are placed at the bottom of the pipeline. Finally, holes are drilled in the angle steel and screws are inserted to reinforce the overall protection device. When the pipeline is buried too deep, the screw and steel bar welding combination can be used to adjust the suspension length.

The ground beam is made of double HW300*300 steel, the screw is M20*0.3m, the angle is 10*10*0.5cm, the steel bar is C18, and the wood is 40*90mm. Subsequent use needs to select the appropriate specifications and materials according to the on-site excavation conditions.

Processing and manufacturing steps of suspension protection device:

(1) Waste material selection: Use scrap steel, steel bars, and wooden beams left over from construction on site. However, the appropriate specifications must be selected based on the site's topography, excavation conditions, etc.

(2) Erection of ground beams: Based on the width of the on-site pipelines and the excavation of the foundation pit, select scrap steel such as steel sections or channel steels on site and overlap them vertically and horizontally to form the skeleton.

(3) Place angle steel and wooden beams: Place angle steel on the top of the steel section, and then place wooden beams and angle steel at the bottom of the pipeline. The spacing between angle steels should be 1m (depending on the importance and characteristics of the pipeline to be protected on site).

(4) Drilling holes: Drill holes on the angle steel.

(5) Install the screw and nut.

(6) Welding screws and steel bars.

In summary, the utility model can ensure the molding quality and can be used in a turnover manner. It can not only protect the environment and save resources, but also be green, low-carbon and environmentally friendly, and can reduce costs.
