A high-altitude unmanned mobile spraying construction method and spraying equipment

Abstract

The invention belongs to a construction method for high-altitude unmanned mobile guniting and guniting equipment. The method comprises the following steps: a lifting basket is used for supporting a guniting head; an operator holds one ends of nylon ropes wound around corresponding guide wheels; and the lifting basket and the guniting head are controlled to finish guniting. The guniting equipment comprises a windlass, a mixer and an air press, and further comprises the lifting basket, lifting arm support columns and parallel lifting arms for bearing the guniting head to finish guniting of an area to be gunited. The guniting head is fixed at the middle part of the upper end of the lifting basket. The lifting basket is hooked with a lifting hook at the lower end of a lifting rope of the windlass. The method and the guniting equipment can finish the surface guniting construction of foundation slopes without needing the frame building support in highway or railway construction, and have the advantages of feasible and safe construction method, simple structure, fast construction speed, time and labor saving, low construction cost, good construction quality and good energy saving and environmental protecting effects.

Description

technical field [0001] The invention belongs to a high-altitude unmanned mobile spraying construction method and spraying equipment. Background technique [0002] At present, building roads or railways in mountainous areas often makes the excavation depth of the foundation pit passing through the mountain or facing the mountain at one end large. In the case of soil construction with good soil quality, it is also necessary to adopt the construction method of erecting supports and excavating at the same time, which requires a lot of support and construction time, and the support work and the excavation construction work are carried out intersecting. It is beneficial to the progress of Shi Wang’s excavation; if the foundation pit is dug at one time for the whole section, the depth of the foundation pit will be greater, and the overall support and frame spraying will cost more, consume more steel pipe materials, and the construction cost will also increase significantly; in addi...

Problems solved by technology

In the case of soil construction with good soil quality, it is also necessary to adopt the construction method of erecting supports and excavating at the same time, which requires a lot of support and construction time, and the support work and the excavation construction work are carried out intersecting. It is beneficial to the progress of Shi Wang’s excavation; if the foundation pit is dug at one time for the whole section, the depth of the foundation pit will be greater, and the overall support and frame spraying will cost more, consume more steel pipe materials, and the construction cost will also increase significantly; in addition The depth of some anchorage surfaces in mountainous areas is often more than 30 meters, and the risk of supporting the scaffolding is relatively high. However, repeated removal and removal of the scaffolds will result in slower construction speed, time-consuming and laborious, and high construction costs. Concrete needs to be sprayed on the anchorage surface, or the bedrock surface of the base slope or on the base slope to fix and increase the strength of the base slope
