Description

Pressure device of stirring pile machine and stirring pile machine

Technical Field

The utility model relates to a stake machine technical field, in particular to pressure device and stirring stake machine of stirring stake machine.

Background

At present, cement mixing piles are classified into single-shaft, double-shaft and three-shaft mixing piles according to the main construction method. The working principle is that the slurry curing agent is sprayed into the reinforced soft soil by high pressure in the process of drilling by using a deep layer stirrer, and the curing agent and the in-situ soft soil are forcibly stirred and mixed in situ by means of the rotation of a drill bit blade specially made on machinery. The curing agent is subjected to a series of physical and chemical reactions, so that the original soil of the pile position is hardened from soft to hard, and a pile body with good integrity, strong water stability and high bearing capacity is formed. The interaction between the pile body and the soil between the piles forms a composite foundation with greatly improved bearing capacity compared with the natural soft soil foundation. The curing agent used in the actual engineering is mainly cement or lime which is sprayed and stirred into cement-soil piles or lime-soil piles.

The single-shaft stirrer is high in machine frame, light in weight and feet and has certain potential safety hazard, the drill bits are four cross-shaped blades, stirring is not uniform once and needs to be repeated, and only one spiral drill hole is formed, so that the efficiency is low when hole forming and cement adding are carried out together for stirring, and the construction period is greatly prolonged; the three-shaft stirrer has a large matching among the frame structure, the power system and the torque thereof, the three drill bits are long spiral crossed blades, and the air compressor is attached to the construction for air injection, so that the stirring is uniform and sufficient, the stirring effect is improved, the pile forming quality is high, and the water stopping performance is good. Compared with other supporting piles, the triaxial mixing pile has high construction speed, and the pile forming time of each pile is about 30-40 minutes (about 60m can be completed in 24 hours); the water stopping effect is obvious after the pile is formed; the mechanical automation control is realized, and the operation procedure is simple; the labor investment is less, and the construction cost is low; and the triaxial mixing pile can be constructed after the groove is excavated, a mud pit is not needed on site, and the safety and civilization of the construction site are guaranteed. After the section steel is inserted, the triaxial mixing pile plays roles of water stopping and supporting, and meanwhile, the section steel can be recycled. Under normal conditions, the triaxial mixing pile machine carries out pressure mixing through self weight, and the problem of low construction efficiency exists.
