Recently，In 1xbet review New Dollar Company 9111 Median Gas Drainage Lane，A full-section shield machine moving forward。430 meters deep underground，This 108-meter-1xBet bonus code steel "1xBet bonus code dragon" successfully turned the 387-meter-1xBet bonus code U-shaped bend，Enter new position。This is not only the first time that a coal mining enterprise in Shanxi Province has used a shield machine to construct a small-radius U-shaped turn tunnel，Also reached the maximum daily footage of turning excavation of 15.A great achievement of 1 meter，Accumulated valuable experience for rapid excavation of rock tunnels。
“Compared with straight line excavation，The fuselage status of the shield machine during turning tunneling、Higher requirements for transportation systems and working steps、More accurate，In addition, the roadway has a slope turn of 4 degrees and 12 minutes，The shield machine is 1xBet bonus code，The difficulty and intensity of construction are unprecedented。”1xbet reviewXinyuan Company Deputy General Manager Liu Chong told reporters。
9110、9111 The two median gas extraction lanes are 3500 meters 1xBet bonus code in total，U-shaped tunnel composed of two 1/4 arcs connected。This is the third operation line of 1xbet review Xinyuan Company using shield tunneling machine。Consider the large amount of disassembly and installation work of the shield machine、1xBet bonus code construction period，The company decided to adopt U-turn continuous construction method，Exchange time for space，Shorten the work surface appearance period。
"To ensure that 1xBet bonus code turns without deviation，Geological surveyors have to measure and orient the tunnel of the shield tunnel every day，Fine-tune the profile trajectory at any time according to the actual geological conditions and layers underground，To meet design and construction needs。A total of 6 slope adjustments for this turning section。”1xbet review Zhang Zeyu, deputy director of the Geological Survey Department of Xinyuan Company, told reporters。
Introduced by Liu Chong，With traditional cannon digging、Comprehensive excavation comparison，1xBet bonus code excavation has strong continuity、High operating efficiency、Environmentally friendly and other advantages。At the same time，The tunnel tunnel excavated by 1xBet bonus code is well formed，Little impact on the stability of the surrounding rock of the tunnel。It comes with temporary support device and anchor drilling system，High safety factor，Can effectively reduce workers’ labor intensity，Improve support efficiency。In addition，1xBet bonus code uses a laser guidance system to control the tunnel excavation direction，Can greatly reduce the probability of lane misalignment，All data is automatically stored，Conducive to subsequent scientific decision-making。
Early this year，Aiming at the upcoming turning construction of the 9110 median gas drainage tunnel，1xbet review Xinyuan Company plans and deploys in advance，Discussed the construction process many times，Comprehensively consider various factors such as working space，Formulate a set of construction plans suitable for on-site operating conditions。In order to adapt to small radius turning excavation，Technicians adjust the direction of the torque beam connector and the cylinder of the main part of 1xBet bonus code，The second transport bridge was shortened and a batch of belt deviation prevention devices adapted to turning were customized，Fix all turning belt racks with ground anchors，Make it more stable during turns。
Gao Jinchuan, the person in charge of the tunnel construction, introduced to reporters，In order to ensure that all the gangue that falls after tunnel excavation can be transported out，1xBet bonus code changes steps every time，The staff will make adjustments to the transportation equipment，To better adapt to the roadway trajectory，Ensure the continuity of belt operation。
The guidance measurement data screen in the main control room changes from arc to straight line，marks that 1xBet bonus code successfully completed the second arc of turning construction，Enter 9111 Median Gas Drainage Alley。1xbet review Xinyuan company’s relevant person in charge said，The continuous turning operation of 1xBet bonus code was completed with high quality，Not only solved the slow construction progress of gas drainage tunnel，The problem of gas drainage restricting the connection of mining，It also shortened the tunnel excavation period，Reduces the cost of tunnel support and equipment disassembly and installation，A new construction method for soft rock tunnels has been formed。
According to statistics，This U-turn of 1xBet bonus code saved a total cost of 7.5 million yuan，High productivity for enterprises、Efficient、High-quality development plays a positive role。
