Slope emergency rescue supporting device and method

Abstract

The invention relates to the technical field of slope emergency rescue, and discloses a slope emergency rescue supporting device and method. The slope emergency rescue supporting device comprises a lattice beam structure, a pre-stressed anchor cable structure and slope surface spray anchor structures, wherein the lattice beam structure comprises a first profile steel ground beam, a second profile steel ground beam and a concrete anchorage pier, the first profile steel ground beam and the second profile steel ground beam are arranged at an included angle, the concrete anchorage pier is arranged at the intersection of the first profile steel ground beam and the second profile steel ground beam, the second profile steel ground beam is clamped between the first profile steel ground beam and the concrete anchorage pier, the pre-stressed anchor cable structure sequentially penetrates through the concrete anchorage pier, the second profile steel ground beam and the first profile steel ground beam and extends into the side slope structure, and the slope surface spray anchor structures are arranged between and around the first profile steel ground beam and the second profile steel ground beam. According to the method, secondary disturbance of the soil body caused by foundation trench excavation is avoided, foundation trench excavation time is saved, the construction progress is accelerated, and the method has the advantages of being short in construction period, high in safety and good in economic benefit and is suitable for slope emergency rescue construction engineering.

Description

technical field [0001] The invention relates to the technical field of slope rescue, in particular to a slope rescue support device and a support method. Background technique [0002] Under complex geological conditions in mountainous areas, the original slope or mountain collapses or landslides due to geological disasters or other reasons, thus affecting the safety of nearby structures during operation. The engineering environment in the dangerous place is harsh, the construction conditions are limited, and the safety risk is extremely high. The secondary disaster of the slope is always faced, which brings personal danger to the personnel who are in the rescue. How to quickly complete slope disaster treatment with as little disturbance as possible in a limited space is the key point of emergency engineering. [0003] At present, the deep reinforcement method of soil slope adopts the prestressed anchor cable (bolt) sash beam reinforcement. In the reinforcement project of hi...

Problems solved by technology

[0005] However, for slope emergency projects, the rescue time is urgent, and the danger needs to be resolved as soon as possible. When the conventional anchor cable (anchor) frame beam is used to construct the ground beam, it is necessary to excavate the foundation groove, tie the steel bars, support the formwork, and pour the ground. Beam concrete, equal strength and post-tensioning, the construction time is longer

At the same time, the inside of the conventional anchor cable (bolt) sash beam is greened by planting grass seeds, which is not suitable for rainwater infiltration soil slopes, so as to avoid damage caused by sliding at the interface between the slope soil and the underlying bedrock
