Xinxiang Acoustic Detection Pipe Grouting Pipe Settlement Board Manufacturer 3-Xiaoshen National Delivery Xinxiang Acoustic Detection Pipe-Xinxiang Grouting Pipe Xinxiang Settlement Plate Whether the equipment is normal and safely maintained is completely reliable. After the installation of the acoustic tube is completed, visually check whether the installed acoustic tube is erected in a straight line from top to bottom. Select the material of the acoustic tube to ensure maximum sound transmission and ease of installation. and the lowest cost is the principle. There is mud or necking in the local section. . The joint should have a smooth transition. The bottom of the acoustic pipe should be sealed with a welded blind cover or steel plate to ensure that it does not leak grout. After the installation of the acoustic pipe, the upper opening should be capped or plugged to prevent watering. Foreign objects fall into the concrete, causing the holes to be blocked. The main specifications of the spiral-threaded acoustic pipe can also be flanged. The manufacturer provides acoustic pipes. What are the types and differences of spot acoustic pipes? Flange-type acoustic pipes are pile foundation acoustic pipes. It is a type of acoustic detection pipe, which is mainly used for deep pile foundations. The wall thickness of the flange acoustic detection pipe is larger than that of the clamp-type acoustic detection pipe. Appearance quality requirements of acoustic tubes. . The deformation of the pipe is operated by the acoustic pipe. The joint is clamped into two large ends and a small one in the middle, so that the joint is stuck at one time and avoids the possibility of loose joints. The fixation method can be welding or banding. When welding is used, it should be avoided to burn through the acoustic tube or form welding lesions on the inner wall of the tube, which will affect the straightness of the acoustic tube.
According to the website of the National Development and Reform Commission, in 2019, the national railway coal shipment volume dropped by 100 million tons year-on-year. Among the main coal transportation channels, the Daqin Line completed a coal transportation volume of 100 million tons, a year-on-year decrease. The Houyue Line completed a coal transportation volume of 0.2 billion tons, a year-on-year decrease. The latest data from the National Development and Reform Commission show that railway coal shipments totaled 0.3 billion tons in January 2020, a year-on-year decrease. In addition, Zeng Hao also said that the coal shipment volume of the Daqin Line dropped by about 1.5% year-on-year in this month, hitting a historical low.
Zeng Hao said that in addition to the decline in freight volume caused by the downturn in the coal market, the transportation costs of automobiles have become increasingly lower in the past two years, which has also greatly squeezed the coal railway transportation market. Two years ago, the transportation distance was within 3 kilometers, and car transportation was relatively cheap. One year ago, the transportation distance was within 1,000 kilometers, and car transportation was relatively cheap. Currently, the transportation distance is within 700 to 800 kilometers, and car transportation is relatively cheap.
