Description

Technical Field

[0001] The invention relates to the technical field of external direct buried pipe network, and in particular to an automatic sand-shaking laying device for direct buried pipes. Background Art

[0002] At present, when constructing external network direct buried pipes, the laying of direct buried pipes requires foundation pit treatment first. The bottom of the on-site foundation pit is mostly filled with shaken sand manually, which has high labor intensity, large workload and low construction efficiency. The particle size of the shaken sand manually filled on site is difficult to control, which affects the subsequent foundation pit construction and the laying construction of the direct buried pipes, and affects the construction progress.

[0003] At the same time, the working conditions of foundation pit construction are complicated, especially for deep foundation pit construction. Some sites have groundwater and support difficulties, which makes it difficult to shake the sand in the foundation pit. The personal safety of construction workers is also difficult to guarantee. The complex working conditions at the bottom of the foundation pit also make the thickness of the artificially laid shaking sand uneven, and the elevation of the bottom of the foundation pit cannot be effectively controlled. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an automatic sand-shaking laying device for direct-buried pipes. Before the sand-shaking laying, a field-leveling mechanical arm is used to hammer the uneven ground in the site, and then the elevation control unit is set at the front end of the automatic laying device to effectively control the thickness of the sand-shaking, thereby ensuring the sand-shaking elevation at the bottom of the foundation pit and ensuring that each section of pipe can be constructed and operated on the sand-shaking, which is convenient and improves work efficiency. A vibrating particle size control net is arranged inside to control the particle size of the laid sand-shaking, thereby improving the quality of the sand-shaking laying, thereby achieving the purpose of saving time, saving labor, and ensuring construction quality.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A direct buried pipe shaking sand automatic laying device comprises a laying trolley, a control panel, an adjustable conveying device, a field leveling mechanical arm, a main engine power system integration, a particle size control network, walking wheels, an elevation control unit and a push-pull handle.
