A dense sand and gravel filling device and construction method

Abstract

The invention discloses a compaction-type sand gravel filling device and a construction method. The compaction-type sand gravel filling device comprises two tracks, an adjustment device, a traction rope, a traction device and a sand gravel filling box. The adjustment device comprises an adjustment frame, a rotary rod and an adjustment rod. The sand gravel filling box comprises a first mounting support, a second mounting support, a feeding part, a buffering part and a discharging part. The construction method comprises the steps of a, digging of a sand gravel filling pit; b, arrangement of thetracks; c, arrangement of the adjustment device; d, arrangement of the traction device; e, hoisting and placing of the sand gravel filling box; f, sand gravel filling; g, repeating of the step e and the step f; and h, compaction of a sand gravel layer. By adoption of the compaction-type sand gravel filling device and the construction method, the sand gravel filling pit can be orderly filled with sand gravels in one direction, so that the structure of the sand gravel filling pit is prevented from being damaged; the construction difficulty is lowered, and the construction quality of an ecological retaining wall is improved; and meanwhile, the sand gravel layer can be laid rapidly by only one person, so that the labor cost is reduced, and the construction process of the whole ecological retaining wall is shortened.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a dense sand and gravel filling device and a construction method. Background technique [0002] Ecological restoration refers to stopping human disturbance to the ecosystem to reduce load pressure, relying on the self-regulation and self-organization capabilities of the ecosystem to make it evolve in an orderly direction, or using the self-recovery ability of the ecosystem, supplemented by Artificial measures to gradually restore the damaged ecosystem or make the ecosystem develop in a virtuous cycle; mainly refers to the restoration and reconstruction of the natural ecosystem that has been damaged by natural mutations and human activities, and restores the ecosystem. The original appearance. [0003] Ecological river restoration is one of the fields of ecological restoration. At present, ecological retaining walls are used to restore ecological rivers...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when a layer of dense sand and gravel is filled in the pit, the gravel is poured directly into the pit first, and then the accumulated gravel is gradually leveled. In this process, the forklift cannot be driven into the pit, so It is necessary to level the accumulated sand and gravel manually. Due to the high height of the accumulated sand and gravel, many people are required to level the accumulated sand and gravel, and it takes a long time to level the accumulated sand and gravel, which affects the construction progress of the entire ecological retaining wall; at the same time When pouring sand and gravel, it is easy to damage the structure of the pit and affect the construction quality of the ecological retaining wall
