On February 11, 2017, when the Lantern Festival was approaching, the foundation construction of 21 drilled piles on the 4# main pier of the main bridge construction of Heilongjiang Bridge was successfully completed, which indicates that the temporary construction of Heilongjiang Bridge has been carried out one after another. After the first bored pile of the Heilongjiang Bridge was successfully poured on January 22, in order to complete and open to traffic as soon as possible, the No. 8 Project Department of Longjianyi Company was in full swing, and the construction continued until the twenty-ninth day of the twelfth lunar month, when people were still enjoying it on the sixth day of the first lunar month. During the holiday brought by the Chinese New Year, all the construction and production personnel of the Eighth Project Department began to devote themselves to intensive construction and production tasks. The TS-K100 automatic ultrasonic hole-forming and groove-forming detector provided by Wuhan Tianchen Weiye Geophysical Prospecting Technology Co., Ltd. played an important role in this construction, and effectively ensured the smooth development of the project.
Heilongjiang Bridge overcomes various difficulties in the construction of bored piles. Because the design of the bored pile foundation adopts the form of expanded bottom piles with a diameter of 1.5m, the diameter gradually expands from 1.5m to 2.5m within 3m of the pile end. Bottom expansion and drilling are the key to the construction of bottom expansion bored piles. The expansion diameter of the bottom expansion drill bit is 100cm, the vertical corresponding stroke of the drill pipe is 30cm, and the drill bit expansion is divided into three gears, so each time it is necessary to pass the adjustment limit. Position the spacer block to control the maximum diameter of the reaming hole.
Although the temperature in winter is low, Wuhan Tianchen TS-K100 automatic ultrasonic hole forming groove detector has withstood the test of the extremely cold weather in Northeast China. Accurate test results have made great contributions to the inspection of the construction effect of the expanded bottom pile, which is highly affirmed and appreciated by the construction party!
