Semi-automatic cement mixing pile strength uniformity device

Abstract

The invention discloses a semi-automatic cement mixing pile strength uniformity device which comprises a cement storage tank. The cement storage tank is provided with a screw conveyor, and the screw conveyor is connected with an automatic cement paste mixer through a section of cement conveying pipe; the device also comprises a slurry pump and a pressure buffer tank; and the automatic cement pastemixer is provided with a cement paste flow control box and an automatic mixer control box. According to the semi-automatic cement mixing pile strength uniformity device, through a semi-automatic cement slurry mixer, a pressure pump and a flow meter, the water-cement ratio and the cement slurry flow are accurately controlled, and the design parameters are effectively controlled, so that the pile forming quality of a cement mixing pile is effectively guaranteed. The device can meet the construction safety requirement, is convenient to construct, and has remarkable semi-automatic pile forming quality effect.

Description

technical field [0001] The invention relates to a semi-automatic cement mixing pile strength uniformity device, which belongs to the technical field of cement mixing pile construction. Background technique [0002] In construction engineering, cement mixing piles are widely used in domestic soft soil foundations because of their simple construction process, obvious reinforcement effect, no vibration and pollution during construction, no adverse effects on surrounding buildings, short construction period and low cost. widely used. However, in engineering applications, due to the relatively conservative design method, the replacement rate is as high as 40% to 80%. There is a phenomenon of "slurry overflow" during the construction of cement mixing piles, and the cement content in the upper part of the pile body is higher. [0003] less cement content. During construction, only the total amount of cement and the average amount of mixing can be controlled, but the amount of cem...

AI Technical Summary

Problems solved by technology

During construction, only the total amount of cement and the average amount of mixing can be controlled, but the amount of cement mixing per unit length cannot be quantitatively controlled. The ratio of cement mixing is unevenly distributed along the depth of the pile body, there are weak surfaces, and the quality of piles is not monitored.
