螺旋式声测管可直接固定在钢筋笼的内侧，声测管固定点的间距不超越2米，其间螺旋式声测管的底端和接头部位有必要设固定点，关于无钢筋笼的部位，螺旋式声测管可用钢筋支架固定或加固三根主钢筋，绑缚间隔不得大于两米。螺旋式声测管的埋设布置应契合的规则。The spiral acoustic pipe can be directly fixed on the inner side of the reinforcement cage. The spacing between the fixed points of the acoustic pipe shall not exceed 2 meters. During this period, it is necessary to set fixed points at the bottom end and the joint of the spiral acoustic pipe. For the parts without reinforcement cage, the spiral acoustic pipe can be fixed or reinforced with three main reinforcements with a reinforcement support, and the binding interval shall not be greater than 2 meters. The laying layout of spiral acoustic pipe shall conform to the rules.
下节钢筋笼螺旋式声测管的装置：把底管或中管放在地上检查密封圈是不是无缺，然后将中管或顶管刺进底管，直到插到管底部停止，然后把螺旋紧固即可。接好后把声测管放入钢筋笼内，按规则尺度紧固在钢筋笼的主筋上。 第二节钢筋笼、第三节钢筋笼以及上面一节钢筋笼声测管的装置：把不一样长度的螺旋式声测管放在不一样长度的钢筋笼内(声测管的长度和钢筋笼的长度相对应)。声测管按步办法装置，留意密封圈的无缺。然后用铁丝穿过螺旋式声测管上的吊环，把装置好的声测管吊在钢筋笼上不要过紧能上下移动即可。向钻孔内下放钢筋笼时螺旋式声测管的装置办法：节(下节)钢筋笼下入钻孔后，应把声测管内加满清水。然后焊接第二节钢筋笼。焊接结束 ，把上面的声测管用手托起刺进下面声测管的承口端，用螺旋紧固即可，然后下放钢筋笼每到两米时需用铁丝把螺旋式声测管绑扎在钢筋笼主筋上，第二节钢筋笼下放完把螺旋式声测管内加满清水。
The device for the spiral type acoustic pipe of the reinforcement cage in the next section: put the bottom pipe or middle pipe on the ground to check whether the sealing ring is intact, and then stab the middle pipe or top pipe into the bottom pipe until it stops at the bottom of the pipe, and then tighten the screw. After connection, put the acoustic pipe into the reinforcement cage and fasten it on the main reinforcement of the reinforcement cage according to the regular dimensions. The second section of reinforcement cage, the third section of reinforcement cage and the above section of reinforcement cage acoustic pipe device: put the spiral acoustic pipe with different length in the reinforcement cage with different length (the length of the acoustic pipe corresponds to the length of the reinforcement cage). The acoustic tube shall be installed step by step, and the sealing ring shall be intact. Then use the iron wire to pass through the lifting ring on the spiral acoustic pipe, and hang the installed acoustic pipe on the reinforcement cage without being too tight to move up and down. Installation method of screw type acoustic pipe when placing the reinforcement cage into the borehole: fill the acoustic pipe with clean water after placing the reinforcement cage into the borehole. Then weld the second reinforcement cage. After welding, hold up the upper acoustic pipe by hand and stab it into the socket end of the lower acoustic pipe, and fasten it with screws. Then, when the reinforcement cage is lowered to two meters, use iron wire to bind the spiral acoustic pipe to the main reinforcement of the reinforcement cage. After the second reinforcement cage is lowered, fill the spiral acoustic pipe with clean water.
