摘要： Detecting and locating leaks in building service lateral sewer pipelines is accomplished under remote control by inserting a lateral inspection television camera into the lateral pipeline from a main sewer pipeline. The lateral inspection camera is stored in a generally cylindrical launcher mechanism having a camera port opening through which the lateral camera may be projected and retracted using a hollow elongated and flexible push rod. The launcher is moved longitudinally in the main pipeline, along with a main television camera, until an entrance opening to a service lateral pipeline is viewed via the main camera. The launcher mechanism may also be rotated in order to properly align the camera aperture with the entrance to the lateral pipeline. The lateral camera can be propelled into the lateral pipeline by means of motor driven pinch rollers in the launcher mechanism pushing the push rod. Electrical power and video signals for the miniature camera are transmitted through a cable disposed within the push rod. An electronic switch is disposed in the launcher mechanism and is selectively actuable from a remote control station to effect alternative transmission of the lateral camera video signal and the main camera video signal to the remote control station.

摘要翻译： 检测和定位建筑服务侧下水管道中的泄漏是通过将侧面检查电视摄像机从主污水管道插入侧管道进行远程控制的。 侧面检查照相机存储在具有相机端口开口的大致圆柱形的发射器机构中，侧摄像机可以使用中空的细长且柔性的推杆突出和缩回。 发射器在主管道中纵向移动，连同主电视摄像机，直到通过主摄像机观看到服务侧管道的入口。 发射器机构也可以旋转以便将照相机孔径与侧向管道的入口正确对准。 侧向摄像机可以通过推动推杆的发射器机构中的电机驱动夹送辊被推进到侧管道中。 用于微型照相机的电力和视频信号通过设置在推杆内的电缆传输。 电子开关设置在发射器机构中，并且可从远程控制站选择性地致动，以实现侧向摄像机视频信号和主摄像机视频信号到遥控站的替代传输。

摘要： A system for cutting lateral holes in plastic pipe liners at the locations of lateral taps in a surrounding pipe comprises a cylindrical body which is inserted into the pipe liner, and remote devices for observing and controlling operation of the body. A rotary cutter, having axial and radial cutting teeth, can be remotely translated in three dimensions with respect to the body, making it possible to cut non-circular holes; the body can be rotated about its axis within the liner as well. A video camera on the sled permits observation of the cutter. Lateral taps are precisely located by monitoring return signals from a microwave transmitter/receiver on the sled, and identifying points of maximum deviation in microwave reflection.

摘要： A method and apparatus for detecting and sealing leaks in a sewer branch pipe including a packer member which travels along the main sewer pipe by remote control. When the packer is correctly located, the main pipe region surrounding the branch entrance is sealed off. The packer is rotated until a slot in the packer is orientated to the branch. An inflatable tube in the packer is then inflated, causing the tube to elongate and enter the branch. The remote end of the tube forms a seal against the inside of the branch so that the area of the branch near the junction with the main pipe is included in the sealed off area. Fluid can be pumped into the sealed off space to detect if a leak is present; in which case a sealant fluid is pumped into the space. Afterwards, the tube can be deflated and retracted and the traveller repositioned at the next branch. The disclosure includes a method of detecting and sealing leaks, in which an inflatable tube is used to provide a means to enter the branch, and to seal the branch away from its junction with the main pipe.
摘要翻译： 一种用于检测和密封包括通过远程控制沿着主污水管行进的封隔器构件的下水道支管的泄漏的方法和装置。 当封隔器正确定位时，分支入口周围的主管区域被密封。 打包机旋转直到封隔器的插槽朝向分支。 然后将封隔器中的可充气管充气，使管伸长并进入分支。 管的远端形成对分支内侧的密封，使得在与主管的连接处附近的分支区域被包括在密封区域中。 流体可以泵送到密封的空间中以检测是否存在泄漏; 在这种情况下，密封剂流体被泵入空间。 之后，管可以放气和收缩，并且旅行者在下一个分支处重新定位。 本公开包括一种检测和密封泄漏的方法，其中使用可膨胀管来提供进入分支的装置，并且将分支密封离开与主管的连接处。
