Problems solved by technology

[0004] The main problem of existing horizontal drilling rigs is that the power of the power head comes directly from the motor. Since the construction is underground, safety accidents such as electric leakage and electric shock are prone to occur during the construction process, which endangers the personal safety of underground construction personnel, and motor failure often occurs due to flooding. scrapped accident
In addition, these drilling rigs cannot adjust the angle, so that the levelness of the horizontal pipe construction cannot be guaranteed, which affects the construction quality, and the screw rod is generally used to support the well wall, which affects the support effect

Abstract

Above ground part of well includes power station, high-pressure hydraulic pump and high-pressure oil pump. Underground part of well is full hydraulic system including power transmission system, chassis supporter, manipulator system, drill pipe and drilling bit, balancing and positioning system, and landing gear of angular adjustment. Hydraulic motor drives rotation of drill pipe, and hydraulic ram controls drill pipe for going forward or back. Features of the invention are high safety ensured by full hydraulic system in underground part, powerful drilling force, easy to adjust angle of drilling machine. The invented system is suitable for developing and controlling shallow groundwater, irrigation of agricultural land, city water supply and lowering level of water in pothole etc.

Description

technical field [0001] The invention relates to equipment for the construction of horizontal radiation tubes in radiation wells, which belongs to civil engineering construction machinery. Background technique [0002] The radiation well is composed of a large-diameter reinforced concrete pipe shaft and a certain length of multi-layer, several or dozens of horizontal radiation pipes driven from any elevation and horizontal direction aquifer in the shaft. The shaft is the place where the horizontal radiant tube is constructed, water is collected, and the pump is installed to drain the water out of the well. The horizontal radiant tube is used to collect the groundwater from the aquifer into the shaft. [0003] At present, the equipment used for the construction of horizontal pipes in radiation wells at home and abroad mainly contains two types: horizontal drilling rigs and jacking machines (jacks), which are respectively applicable to drilling method construction and jacking (...
