Three of Henan Machinery Manufacturing Co., Ltd. successfully test machine screw pile driver

Henan Sanli Machinery Manufacturing Co., Ltd. in May 21, 2014 off the assembly line production plant from 35 a screw pile, piling depth of 35 meters, less unearthed, high efficiency. Screw pile to pile spiral, screw piles and steel fiber developed in Japan all the advantages of precast concrete piles spiral, with the absence of screw piles pile clear bottom, Wall, the collapse of the hole, off the pile, necking and other issues, pile quality and reliable, won the praise of the majority of foundation engineering workers. Characterized by its technical pile consists of two parts, the upper part of the pile rectilinear equal diameter cylinder, the lower end portion of the pile head and vertebrae to expand and expand the diameter of the cylinder head and the vertebral body diameter of 1.0 to 2.0 times the Inter, when the expansion of the head of the vertebral body diameter 1.0 times the diameter of the cylinder, the cylinder piles of equal diameter, referred to as rotary extrusion CFG pile. The piles due to soil compaction pile type, pile capacity than ordinary casting pile high, with per cubic meter of concrete than ordinary concrete piles with less, save the cost and speed of construction, quality of pile readily available protection. Screw pile technology advantages: 1, by a mechanical one-time squeeze into the hole into the pile, not borrow, partly soil; 2, single construction 750-1000 meter per day (500mm diameter piles calculation); 3, depending on the length ratio of the soil can be adjusted with the threaded section of the screw, with the pump pressure irrigation concrete pile; 4, the first use of the drill torque technology to determine pile capacity to solve the in-situ concrete can not be predicted in advance bearing capacity problems ; 5, the first rotary power and enhance the power of synchronous technology and asynchronous technology; 6, the first output torque of 25 t m; 7, the first high-torque drill hex-head quick connector; 8, the first pile of Networked Control system. Day test drive site, many construction workers have raised the camera to take pictures or video, three of the successful screw pile technology and manufacturing capability to make the industry praise, three of the machinery screw pile another walk in Henan Piling industry forefront. The pile stood the test of hundreds of projects, overcome all kinds of soil, both for 400KPa strongly weathered rock and gravel content of 50% of the complex soil can ease into the hole into the pile, the synchronization error of millimeters, output smooth torque.
