Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe jacking, in particular to a long-distance curved pipe jacking engineering deviation correction device. BACKGROUND

[0002] The current domestic clearing technical field for hard large obstacles mainly has eight forms of vertical shaft excavation, drilling removal, slow speed top grinding, cabin opening and clearing, casing pipe obstacle removal, jacking butt joint, drilling and blasting removal, and pipe jacking back-off.

[0003] Drilling technology is prone to hole collapse in soft and complex bottom layers, and drilling and blasting and back-off methods will form high cost and have a great impact on the surrounding environment such as the bottom layer, which is not conducive to civilized and environmentally friendly construction. In addition, these methods are usually applicable to conditions such as shallow burial depth or single surrounding environment above and below ground, and wide construction site. For large burial depth pipe jacking operation area, these methods are not applicable.

[0012] Further, the inner support assembly further comprises a V-shaped pin and a pull rod, the inner support claw top portion is rotatably connected with the V-shaped pin through a trunnion, and the V-shaped pin tail end is rotatably connected with the pull rod.

[0013] Further, the inner support assembly further comprises a middle groove, a spring and an oil cylinder, the pull rod is slidably arranged in the middle groove, the pull rod is elastically connected with the middle groove inner bottom end through the spring, the pull rod is fixedly connected with the oil cylinder output end, and the oil cylinder is arranged in the base.

[0016] The long-distance curve pipe jacking engineering deviation correction device has the following beneficial effects:

[0017] 1. During the use of this invention, after the shaft construction is completed, the base is lowered to the preset height by a winch. Then, the base is supported on the inner wall of the concrete retaining wall by the internal support component. In use, the pull rod is pulled by the hydraulic cylinder. Under the transmission action of the V-shaped pins around the pull rod, the internal support claws are simultaneously protruded into the side groove. Through the stable support of the inner wall of the concrete retaining wall, a stable environment is provided for the subsequent construction of the drilling component and the crushing component, preventing the drilling component and the crushing component from deviating from the preset processing position during drilling and splitting operations, and ensuring the accuracy of the position of the boulder splitting operation.

[0018] 2. During the use of this invention, the pipe jacking machine head is located at its underground excavation position via a built-in GPS positioning module. Simultaneously, construction personnel on the ground receive signals from the GPS positioning module via handheld terminals to determine the location of the pipe jacking machine head. Through measurement and positioning, a vertical shaft is excavated downwards in reverse, with support and reinforced concrete retaining walls constructed as excavation progresses. The excavation diameter and depth are determined based on the location and size of the boulder in front of the pipe jacking machine head. The vertical shaft is excavated to directly reach the location above the weakly weathered large boulder, reducing the difficulty of insufficient construction space for breaking up large boulders in front of the pipe jacking construction. In addition, a laser emitter with its central axis is installed at the front end of the pipe jacking machine head. The laser emitter cooperates with laser receivers at both ends of the mounting platform to ensure the drilling position of the drilling component and the installation position of the rock-breaking rod of the crushing component. This ensures that the splitting position of the boulder corresponds to the travel direction of the pipe jacking machine head. The axis position of the mounting platform is adjusted by the threaded connection between the slider and the lead screw, and the rotation adjustment of the mounting platform by the motor through the rotary table is used to correct the construction position of the drilling component and the crushing component.

[0019] 3. During the use of this invention, the slide block, through its threaded engagement with the lead screw, is driven by the motor to cause the diamond drill bit to descend axially from the pre-set opening position on the boulder until the hole depth is 10 cm below the bottom of the pipe jacking machine head. Afterward, the lifting hoist lowers the splitting rod body via the lifting cable, placing it inside the hole. Hydraulic oil is pumped into the hydraulic channel by a high-pressure oil pump. Under the pressure of the hydraulic oil, the plungers arranged along the extension direction on the surface of the splitting rod body protrude from the sliding hole, causing the plungers to move outwards towards the surrounding area. The expansion generates a huge tension of nearly 1000T, while the internal tensile strength of the boulder is low. The boulder can be easily split in seconds using the splitting rod itself, causing compression inside the hard ore and thus splitting it apart. The mechanical splitting method is used for construction, eliminating the need for emulsion explosive blasting. It is practical and economical, with high precision in breaking up boulders, low noise during construction, and lightweight construction equipment that is easy to hoist down the well. The splitting operation is vibration-free, impact-free, and dust-free, making it green and environmentally friendly, with minimal disturbance to the surrounding strata and environment.
