Acoustic Pipe bridge spot in bondage to pile on top of the steel cage, it should be The sound of a test tube with a thin steel plate welded sealed to prevent foreign matter falling into the tube blockage acoustic tube; 2. Acoustic steel pipe during coupling, the general use of welding or wire port link, welding should be careful not to destruction of pipe, in order to avoid the hole leading to penetrate concrete pouring cement paste when clogged acoustic tube; flax should the wind be at the mouth when the wire wire port links, which also aims to prevent the infiltration of cement paste; 3. Sound bridge Pipe general should adopt steel pipe, PVC pipe and although the price is cheap, but because of the banding, cement hydration heat and other factors and is easily deformed, leading up and down movement of the probe can not be detected, it is generally should not be used; 4. One day, then acoustic tube ends before removing steel sheet pile testing, construction Jiamusi acoustic tube spot before the first test tube acoustic measuring rope inspection, inspection items Steel Association latest data show that in mid-October focus on steel prices Nissan 1.7629 million tons of crude steel, down 2% qoq late. In mid-October, the end of the key enterprises in stocks 15,656,300 tons, 32,000 tons lower than the previous ten days, production fell slightly. This week, APEC meeting will be held in Beijing, had developed a variety of security programs will be formally implemented. View from steel producers, from November 1, steelmakers around Beijing will begin production or limited production, but November is still large steel overhaul efforts, bearing steel, Shougang Jingtang Shougang Qian'an hot rolling production Each line maintenance arrangements, the supply of steel around Beijing will be significantly reduced during the period, particularly in construction steel, profiles and steel and other steel products will become more tense. By then, the early transient resource constraints and pressure relief funds or finished products will drive the spot market prices rose slightly. But Lange Steel Information Research Center, Ma Guanghui Analysts pointed out that the limited production and cut the main spot in Jiamusi acoustic tube around Beijing and Hebei, Jiamusi acoustic tube stock is relatively limited impact on the national market, but taking into account Tangshan etc. spiral, profiles and other resource flows to channel wider and more involving national market, will impact on the market will be relatively sensitive to hot and cold rolled sheet and plate and other products affected or not great.
