Details >Technical advantages of large diameter vibrating immersed tube gravel pile
Large-diameter vibrating immersed tube crushed stone pile is a deep and large-diameter dense pile body composed of crushed stone formed by sinking the steel feed pipe into the design depth by using high-power vibrating hammer as the driving force, filling the gravel into the hopper and silo, and then pulling out the feed pipe through vibration. Compared with the traditional technology of gravel pile, Shanghai Qiangqiang has mature construction technology and experience, and has dozens of gravel pile construction equipment, which has been successfully used in many large-scale foundation treatment projects at home and abroad.
Details >Introduction of water mixing pile construction ship
Water mixing pile construction ship (DCM ship) integrates a number of high-end technologies such as underground soil cutting and mixing, precise injection of cement slurry, high and low slurry nozzle exchange, environmental protection treatment system, intelligent control construction and so on. It is a major technical equipment with high technology and high added value
Details >Quality control: Inspect the steel support of foundation pit to ensure no deformation
From HUAINAN PANJI COAL PREPARATION PLANT TO THE CONSTRUCTION SITE OF THE FOUNDATION PIT SUPPORTING ENGINEERING OF THE UNDERGROUND CORRIDOR OF the power PLANT, Shanghai STRONG management personnel are INSPECTING the steel support of the FOUNDATION pit to ensure no deformation and no noise, so as to ensure the construction quality. The 2X660MW ultra-supercritical Coal-fired Unit Project of Panji Power Plant Phase I of Huainan Mining Group (hereinafter referred to as the "Project") is located in Wangwei Village and Huaibei Village, Jiahe Town, Panji District, Huainan City, Anhui Province, about 0.6km north of Fuhuai Railway.
Details >Introduction of large diameter vibrating immersed tube gravel pile technology
New technology of large diameter gravel pile sinking pipe basically has the following advantages: large pile frame, high power: our gravel pile of big pile frame (see figure 1) capable of carrying power 400/500 kw of high-energy vibration hammer, the crushed stone pile, pile length, pile diameter up to 1200 mm can be more than 30 m, which makes the effective of gravel pile diameter and the depth of pile has a larger breakthrough.
Details >Hong Kong airport is the biggest challenges facing the third runway construction aspect, before the project starts, sea DCM (mixing pile), land DCM (mixing pile), PVD (drain) in the sea, land gravel pile foundation treatment technology such as are for Japan, South Korea, the monopoly of international advanced technology, before and after the tender, the foreign counterparts enterprises of our country executes strict technology blockade. For this reason, the strong foundation has carried on the thorough research. After more than two years of continuous fighting day and night, countless scientific research, testing and adjustment, we have overcome the difficulties of equipment manufacturing and construction technology of PVD (drainage board) engineering ship, DCM (mixing pile) engineering ship, onshore gravel pile machine, and onshore DCM pile machine, and successfully mastered the core technology.
