Embodiment Construction

[0044] Such as Figure 1 to Figure 5 As shown, it is an anti-displacement gravel backfill device of the present invention, which includes a backfill body 1, a mobile handrail 2 and a fixing device. The design of the mobile handrail 2 can facilitate actual installation and subsequent maintenance and repair, and the design is more humane. The backfill body 1 includes a backfill box 3 and a mobile base 8, a feed hopper 4 is arranged above the backfill box 3, and a discharge hopper 5 is arranged below the backfill box 3, and the discharge hopper 5 and the feed hopper 4 are connected to each other. The backfill box 3 is movable and disassembled, and the upper end of the discharge hopper 5 is provided with a crease section 6. The design of the crease section 6 can stretch the length of the discharge hopper 5 according to the thickness of the fixed steel plate 10 to ensure that the bottom of the discharge hopper 5 Located in the gravel foundation pit, the feed hopper 4 is in the shap...

Abstract

The invention discloses a moving preventing rubble backfilling device. The moving preventing rubble backfilling device comprises a backfilling body, a movable handrail and a fixing device. The backfilling body comprises a backfilling box and a moving base. A feeding hopper is arranged above the backfilling box, and a discharging hopper is arranged below the backfilling box. The backfilling box islocated on the moving base. The fixing device comprises a fixing frame and a fixing steel plate. The fixing frame comprises a fixing sleeve and a supporting frame. A construction method comprises thefollowing steps that a, rubble foundation pit excavation is conducted according to a design drawing; b, fixing steel plate arrangement is conducted; c, backfilling body arrangement is conducted; d, fixing frame arrangement is conducted; e, steel wire rope arrangement is conducted; and f, rubble backfilling is conducted. The moving preventing rubble backfilling device and the construction method are provided, the construction method is simple, mounting and dismounting are convenient and fast, backfilling body installation is firmer through the design of the fixing device, the situation that thebackfilling body moves, and the rubble backfilling rate is influenced is effectively prevented, and operation safety performance is improved.

Description

technical field [0001] The invention relates to a displacement-proof gravel backfill 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. In the process of ecological restoration of the river, since the foundations on both sides of the river are relatively soft, the actual construction strength cannot be achieved. It is necessary to excavate foundation pits on both sid...
