Embodiment 1

[0021] Embodiment 1. This embodiment provides a self-balancing pipe excavation method without foundation pit and pilot hole, including the following steps: (1) The front cutter head 1 and the back cutter head 2 arranged in pairs and rotating in opposite directions are cut by the driving module Provide thrust; (2) balance the sensor 4 in the process of advancing the state of the sensing device, and the controller will control the start and stop of the front and rear cutter head 2 switches to maintain the self-balanced state of the device; (3) turn on The excavated soil is impacted by the water flow and the muddy water is output through the pipe of the hose 5; (4) The drill bit and drive module pull the hose to the target position; (5) Remove the drill bit and drive module, and then clean the pipe to complete the entire construction process. Among them, the rear of the front cutter head 1 and the rear cutter head 2 are also matched with a spiral friction drive block 3, there are ...

Embodiment 2

[0022] Embodiment 2. This embodiment provides a device for a self-balancing pipe excavation method without foundation pits and pilot holes. The device includes a device body. The device body includes a bracket, a cutting part and a driving part. The cutting part includes a pair of front cutter heads 1, For the rear cutter head 2, the driving part includes a spiral friction driving block 3. The device body also includes a balance sensor 4 arranged on the support and sensing the balance state of the device, and a controller that controls the switching of the cutting part and the driving part. In addition, a guide device 11 is arranged at the front of the front cutter head 1, and the position and direction signal of the drill bit is transmitted to the video detector on the ground through the guide device 11 to realize manual adjustment control. There is a hose 5 at the rear of the support. The outermost part of the hose 5 is provided with a sedimentation tank 8 and a clear water ta...

Abstract

A foundation-pit-free pilot-tunnel-free self-balancing pipeline excavation method comprises the steps that a front cutter bit and a rear cutter bit which are arranged in pair and rotate in the reversedirections cut to provide thrust; a balancing sensor senses the state of a device in the propelling process, turning-on and turning-off of switches of the front cutter bit and the rear cutter bit arecontrolled by a controller, excavated soil is impacted by a water flow, and muddy water is output through a flexible pipeline; and a pipeline is laid, and construction is completed. A power part of adevice body comprises the front cutter bit and the rear cutter bit which are arranged in pair, and further comprises spiral-type friction driving blocks which are arranged in pair. A guiding instrument is arranged on the front portion of the front cutter bit. The device body further comprises the balancing sensor arranged on a bracket and sensing the balancing state of the device, and the controller for controlling turning-on and turning-off of a switch of the power part. A flexible pipe is arranged on the rear portion of the bracket. A settling pond and a clean water pond are arranged on theoutermost side of the flexible pipe. The clean water pond is internally provided with a water pipe going deep into the flexible pipe. A water pump is arranged at the water inlet end of the water pipe. No foundation pit and no pilot tunnel are achieved, the pull-back pore broadening process is not needed, and construction is convenient and fast.

Description

Technical field [0001] The invention belongs to the technical field of shallow ground pipeline construction, and relates to a method and device for excavating a self-balancing pipeline without a foundation pit and a pilot hole. Background technique [0002] At present, many existing facilities in the city cannot meet the needs of development. For example, the laying and maintenance of sewage, tap water, gas, electricity and communication pipelines are to "open up" the street and pavement when needed, resulting in traffic jams and damage. There have been a series of problems such as infrastructure and environmental pollution. Trenchless construction technology is to lay, detect, repair and update various underground pipelines without excavation (or less excavation) to solve the problems in urban pipeline construction. [0003] Although the trenchless construction technology has a history of more than 100 years abroad, its large-scale application began in the 1980s, starting from se...
