Sany SR405-S rotary drilling rig has large holes and deep piles, which is economical and efficient

In November 2023, the seaside of Yueqing City, Wenzhou, Zhejiang Province, is undergoing earth-shaking changes, and Binhai Avenue in Yueqing City is in full swing under construction.

Overview:Binhai Avenue Pile Foundation Project, Yueqing City, Wenzhou, Zhejiang, with a pile depth of 110m, a pile diameter of 2m, the number of piles to be formed is 2000, and the configuration is φ580×6×20.2m machine lock rod + 2m sand bucket, the construction geology is mainly based on soil layer and silt, the upper layer of 30m is the silt layer, 30-70m is the soil layer, and 70-110m is the pebble layer.

Model features:

Cost-effective:Users are very satisfied with the cost performance of SR405-S, believing that its pricing is reasonable and the returns are rich, according to the boss, "the machine bought in September will be able to return to its cost in the first half of 2023, and the cost performance is very high."

Efficient construction:Power head torque: 405kN· M, the maximum speed of the main winch is 75m/min, and the compound action is smooth, far exceeding other levels in the same levelThe customer was very satisfied with the product, saying that "one hole can be done a day, which is much faster than the rotary digging at the same construction site, and the boss also made a special trip to see this machine."

Stable and reliable:Special chassis for rotary excavation, low center of gravity, wide spread, stable construction; The box-type mast and double boom luffing structure have strong capacity to bear alternating loads, optimized rope bar configuration, and long service life; The operator spoke highly of the reliability, "working continuously for more than 2 months, without downtime, and the stability and reliability of the rig are very good".

NEW EXPERIENCE:Intelligent cockpit, reasonable air outlet position and sealing design, so that the cab is in a low-noise and constant temperature state; 6 new intelligent functions have been added to reduce the working intensity of the operator, and the centralized lubrication system is equipped as standard, saving time and labor in maintenance.

The construction stratum is mainly soil layer and silt layer, 70-100m mixed with pebble layer, through on-site monitoring, in the case of the selection of friction rod and sand bucket, 110m pile, and the hole formation time is about 18 hours. Its construction efficiency and economic and reliable advantages have been highly recognized by customers, creating the best economic benefits for customers, and its high cost performance has been highly recognized by customers.
