    螺旋声测管的链接

    1、 桩基检测与声测管的埋设布置应符合JTG/T F81-01的规定。
    2、 声测管自进入工地现场后起,在装卸、搬运、安装过程中,要避免使声测管的管体扭曲、挤压变形。声测管要存放在有遮雨设施的场地,避免管体生锈。进场安装的声测管,首先要对管体进行检验,扭曲变形的声测管不允许进入安装程序。
    3、 声测管可直接固定在钢筋笼的内侧,固定点的间距不超过2米,其中声测管的底端和接头部位必须设固定点,对于无钢筋笼的部位,声测管可用钢筋支架固定。
    4、 最下节钢筋笼声测管的安装:把底管或中管放在地上检查密封圈是否完好,然后将中管或顶管插入底管,直到插到管底部为止,然后把螺旋紧固即可。接好后把声测管放入钢筋笼内,按规定尺寸紧固在钢筋笼的主筋上,对于无钢筋笼的部位,声测管可用钢筋支架固定或加固三根主钢筋,捆绑距离不得大于两米。
    5、 第二节钢筋笼、第三节钢筋笼以及最上面一节钢筋笼声测管的安装:把不同长度的声测管放在不同长度的钢筋笼内(声测管的长度和钢筋笼的长度相对应)。按第一步方法安装,注意密封圈的完好。然后用铁丝穿过声测管上的吊环,把安装好的声测管吊在钢筋笼上不要过紧能上下移动即可。
    6、 向钻孔内下放钢筋笼时声测管的安装方法:第一节(最下节)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。 焊接完毕 ,把上面的声测管用手托起插入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声测管绑扎在钢筋笼主筋上,第二节钢筋笼下放完把声测管内加满清水。等最上节钢筋笼下放完后,一定把管内加满清水,最后用盖盖好。
    7、 注意事项:1注意密封圈是否完好。2螺旋必须用专用工具紧固到位。3下放钢筋笼时声测管接头处一定把铁丝从吊环内穿过绑在主筋上。4每下放完一节钢筋笼后必须把声测管内加满清水。5焊接钢筋不要把电焊钳、搭铁线接触到声测管上,以免电焊强流造成声测管破漏。6钢筋笼下放完毕把声测管内一定加满清水,最后用盖盖好、严禁管内进入混凝土或水泥浆。

    Acoustic detection tube 1, pile foundation inspection and embedment decorate should comply with the provisions of the JTG/T F81-01.
    2, acoustic test tube into the tie on a project site, in the process of loading and unloading, handling, installation, to avoid tube body distortion of acoustic detecting tube, extrusion deformation. Sound will be in a test tube block rain venue facilities, avoid tube body to rust. In the installation of tube, the first thing to test for the tube, distorted sound tube is not allowed to enter setup.
    3, sound tube can be directly fixed in the inside of the reinforcing steel bar cage and fixed point distance less than 2 meters, the sound at the bottom of the tube and the connector parts must set a fixed point, for the parts without reinforcing cage, acoustic detecting tube steel bracket.
    4, the installation of the acoustic detection tube section under the reinforcing cage: in the end of the tube or pipe on the ground check whether the seal is in good condition, and then insert the tube or pipe jacking pipe, until it is inserted to the bottom of the tube, then put the screw fastening. After good put sound tube in the steel cage, in accordance with the provisions, size fastening on the main steel reinforcing cage, for parts without reinforcing cage, acoustic detecting tube can use steel bracket or three main steel reinforcement, bundled distance shall not be more than two meters.
    5, reinforcing cage in the second quarter, third quarter reinforcing cage and the top section reinforcing cage acoustic detecting pipe installation: the sound of the different length of tube is placed within the different length of reinforcing cage (the length of the tube and the length of reinforcing cage corresponding). Installed by first step method, pay attention to the sealing ring in good condition. Then with the sound of the wire through the tube on the rings, the acoustic detection hanger installed on reinforcing cage do not overtighten can move up and down.
    6, to lower the reinforcing cage in the borehole drilled in the acoustic detection tube when installation method: the first section (the next) reinforced LongXia into the hole, should add fresh water acoustic detecting tube. And then welded reinforcing cage in the second quarter. After welding, the acoustic detection work hand in order to insert the above below the socket end of the tube, screw fastening, then lower the reinforcing cage every two meters need wire when the sound tube bundle on reinforcing cage main reinforcement, reinforcement in the second quarter LongXia after add fresh water acoustic detecting tube. Such as the section on reinforced LongXia after it finished, must add fresh water pipe and finish with a good cover.
    7, 1 note: pay attention to the sealing ring are in good condition. 2 screw must be fastened in place with specialized tools. 3 down reinforcing cage sound when the measuring tube must be joint through the rings in the wire tie on the main reinforcement. After 4 per delegate section reinforcing cage must add fresh water acoustic detecting tube. Steel bar don't put the electrode holder, welding by wire contact to the acoustic detecting tube, lest cause acoustic detecting welding strong flow tube broken. 6 reinforced LongXia put the completion of the measuring tube must be your voice with fresh water, with good cover, finally it is forbidden to tube into the concrete or cement.
