Full-face stirring and cutting wall construction machine

Abstract

The invention discloses a full-face stirring and cutting wall construction machine. The full-face stirring and cutting wall construction machine mainly comprises a crawler crane, a pulley block, a chain rotating device and a grouting pipe, wherein the chain rotating device mainly comprises a rectangular chain support, a chain, a plurality of knives and a motor; the grouting pipe is arranged on the rectangular chain support; chain wheels are arranged at four corners of the rectangular chain support; a plurality of guiding wheels are distributed on the two sides and the bottom of the rectangular chain support; the chain is arranged on chain wheels and the guiding wheels; the knives are distributed on the surface of the chain at intervals; a crawler crane drives the rectangular chain support to move up and down; the motor drives the chain wheels at the two corners of the upper end of the rectangular chain support to rotate; the chain wheels drive the chain; the chain drives the knives; the knives continuously cut off and stir a rock fracture face; and a plurality of knife dropping preventing mechanisms are distributed on the chain at intervals. The full-face stirring and cutting wall construction machine has the advantages that the full-face stirring and cutting wall construction machine is simple in structure, low in cost, easy to operate, high in efficiency and wide in application range and can adapt to change of rock surfaces of strata.

Description

technical field [0001] The invention relates to civil engineering construction equipment, in particular to a full-section mixing and cutting wall building machine. Background technique [0002] In today's civil engineering construction process, it often involves the construction of underground buildings (structures) such as basements and subways. According to the geological conditions during construction, the foundation pit support body should be constructed first. In areas with rich groundwater, weak soil layers or areas without precipitation conditions, the basement pit support body must also have the function of retaining water and intercepting water. The water intercepting methods mainly include reinforced concrete underground diaphragm walls and lapped cement-soil mixing pile walls. Or high-pressure rotary (pendulum) spray wall, etc. [0003] Cement-soil mixing piles are widely used because of their low cost. Initially, they consisted of single piles with a diameter o...

Problems solved by technology

The height of these traditional deep mixing pile machine racks is limited, relying on overlapping to form a cutoff wall, and the mixing head of the mixing pile is located at the bottom end and can only mix locally. The biggest disadvantage is that the depth of the wall has reached the limit of 35 meters, and the wall The lower part is easy to split, the upper and lower strength is uneven, and the strength is very low when encountering soft soil layers, which greatly affects the effect of retaining soil and water interception
