Problems solved by technology

The use of traditional excavation technology for culvert maintenance and reinforcement often has a greater impact on the normal passage of vehicles
If in-situ reinforcement of the damaged section is required, due to the narrow space inside the culvert, it is very difficult to implement regardless of the construction technology of pouring concrete or sprayed concrete

Abstract

The invention discloses a self-propelled concrete spraying machine with a spray head with functions of automatic rotation and traction. The spraying machine comprises a sled with a sled plate, and a concrete feeding device, with a material mixer, arranged on the sled plate. The material mixer is driven by a driving device to rotate, and the driving device is mounted on the sled plate. Concrete in the concrete feeding device is delivered from the material outlet of the material mixer to a rotary spray head through a pipeline. The concrete spraying machine is mounted on the sled, the material mixer is driven to rotate through the driving device, the concrete is delivered from the material outlet of the material mixer to the rotary spray head through a landscape channel, the trenchless culvert maintenance and reinforcement construction technology is adopted for the entire device, adverse effect on normal road traffic operation is omitted, construction shortcut constructing cost and increased cost due to vehicle detouring are reduced, construction producing efficiency is improved greatly, manual labor is reduced, construction quality is improved, and adverse effect to worker by dust is avoided.

Description

technical field [0001] The invention belongs to the field of concrete mechanical equipment, and in particular relates to a self-propelled concrete sprayer with automatic rotation and traction of a spray head. Background technique [0002] At present, most of the roads and auxiliary structures built during the large-scale construction of expressways in my country in the 1990s have entered the stage of maintenance and reinforcement. With the increasing workload of road maintenance and repair, it is urgent to develop a series of maintenance and reinforcement technologies and equipment with a high degree of mechanization and automation, so as to change the current situation of mainly manual operation and low construction efficiency. [0003] Culverts are an important part of highway engineering. According to the existing technical level, the maintenance and reinforcement of some damaged culverts requires excavation of the subgrade and pavement to replace damaged components for ...
