Sand paving device for hydraulic engineering

Abstract

The invention discloses a sanding device for hydraulic engineering, and relates to the technical field of hydraulic engineering. The device comprises a sliding rail and a winch, the left end and the right end of the sliding rail are connected with supports respectively; a layered sanding device is mounted on the sliding rail in a sliding manner; the layered sand paving device comprises a material distribution box, a material guide plate, a left discharging pipe, a middle discharging pipe and a right discharging pipe; the outer side of the left discharging pipe, the outer side of the middle discharging pipe and the outer side of the right discharging pipe are sleeved with material control sleeves in an up-down sliding mode respectively; the guide plate is fixed to the middle in the material distribution box and located above a screen, and the front end and the rear end of the guide plate are fixedly connected with the front end and the rear end of the inner wall of the material distribution box respectively; a vibration motor is mounted at the rear end of the material distribution box; a pull rope of the winch is detachably connected with the right end of the sliding block. The sanding device for the hydraulic engineering has the beneficial effects that the sanding device better adapts to slope section sand paving, damage to a geomembrane is reduced, sand paving is more uniform, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering. Background technique [0002] Water conservancy projects involve the storage, allocation and utilization of water resources, etc., which are related to economic and social development. In order to make rational use of water resources, it is often necessary to build reservoirs and waterways to mobilize resources. During the construction of the reservoir, a leakage treatment plan is required, that is, geomembrane needs to be laid, and sand material needs to be laid before and after the geomembrane to play the role of cushion or protection. In the conventional laying method, the sand material is laid unevenly and is easy to be The damage caused by the geomembrane directly leads to the failure of the leakage treatment plan and affects the normal use of the reservoir.

During the construction of the reservoir, a leakage treatment plan is required, that is, geomembrane needs to be laid, and sand material needs to be laid before and after the geomembrane to play the role of cushion or protection. In the conventional laying method, the sand material is laid unevenly and is easy to The damage caused by the geomembrane directly leads to the failure of the leakage treatment plan and affects the normal use of the reservoir

[0003] In the existing laying device, the hoist drives the sand truck to carry out the sand laying operation, but the original sand material has a difference in thickness and size, and it is difficult to lay the sand material evenly in one-time laying, especially for the sand material laying on the slope section. When the thickness of the one-time discharge material is large, it is easy to slip, which affects the laying process and the observation and control of the laying thickness. As a result, sand can only be laid from bottom to top, and sand can not be laid from top to bottom or the efficiency and flatness are extremely poor. At the same time there is still the possibility of compressive damage to the geomembrane
