Problems solved by technology

However, there are the following technical difficulties when using the hydraulic splitter static blasting construction method: 1. When the splitting direction determined by the construction design requirements is not on the rock bedding, the breaking difficulty will increase, and the appropriate drilling direction must be determined strictly according to the design , densely arrange the number of drilling holes, and control the drilling angle; 2. The more complicated construction terrain will cause the drilling equipment to be unable to be erected to the pre-designed position, which will make the drilling direction deviate and affect the splitting effect

Embodiment 1

[0070] Hydraulic splitting machine static blasting construction method, such as figure 1 shown, including the following steps:

[0071] Step 1: Construction preparation

[0072] (1) According to the actual situation of the construction site, set up isolation belts and arrange warning lines to prevent nearby personnel and vehicles from entering the construction area by mistake and affecting the construction;

[0073] (2) Retighten all equipment screws before starting the equipment;

[0074] (3) Before starting the air compressor, pay attention to whether the temperature of the motor is normal, whether the readings of the electric meters are within the specified range, whether the operating sound of each part is normal, whether the suction valve cover is hot, and whether the sound of the suction valve is normal. Whether all kinds of safety protection equipment are reliable, check whether the moving parts are flexible, whether the connecting parts are fastened, whether the lubr...

Embodiment 2

[0124] Any object has its own characteristics, rocks and concrete have extremely high external compressive strength, but the tensile strength from the inside to the outside is very small, and its compressive strength and tensile strength have a ratio of 100: (2-10) difference. The splitting machine is designed by grasping the brittle characteristics of rock and concrete, and cleverly utilizing the wedge principle-"a great splitting force can be released outward in the narrowest hole".

[0125] The working principle of the splitting machine: figure 2 As shown, the wedges at both ends are attached to the middle wedge to form a 42mm cylinder-splitter. Drill a number of 42mm holes on the predetermined rock splitting line in advance, then insert the splitter into these holes, start the pump station to supply ultra-high pressure hydraulic oil to the splitting gun, when the hydraulic splitting After passing through the high-pressure oil, the machine can generate thrust in the abov...

Embodiment 3

[0127] Dangerous rock removal project for Weilihe Bridge Pier No. 6 in Wucan section of Lanzhou-Haikou Expressway on G75 line. Dangerous rocks are fracturing beams and columns. The surrounding environment is complex. There are residential areas 100m away from dangerous rocks. Mechanical crushing and traditional blasting cannot be implemented. Under the circumstances, the "static blasting construction technology of hydraulic splitting machine" is used to carry out directional crushing of dangerous rocks, so that there is no secondary hazard, which ensures the construction quality and safety, shortens the construction period, reduces the project cost, and has been awarded by the superior Leaders and local residents alike.

[0128] The static blasting construction technology of the hydraulic splitter has excellent performance in dangerous rock removal, stone mining and various emergency rescue and disaster relief. It also has significant economic and social benefits. It has wide a...

Abstract

The invention relates to the technical field of construction blasting, and particularly relates to a static blasting construction method of a hydraulic splitter. The construction method can greatly accelerate the construction progress, shorten the construction period, reduce the engineering cost, prevent secondary damage to a construction target, reduce the dust pollution, reduce the noise and reduce the vibration when guaranteeing the engineering quality. The construction method comprises the steps of: construction preparation; measurement and hole distribution; drilling acceptance; gun insertion crushing; crushing effect inspection; and waste slag cleaning.

Description

technical field [0001] The invention relates to the technical field of construction blasting, in particular to a hydraulic splitting machine static blasting construction method. Background technique [0002] With the rapid development of my country's economy, the environmental protection situation is getting worse and worse, and the requirements for some construction technologies are getting higher and higher. The construction site requires the use of engineering construction technologies that are pollution-free, pollution-free, high environmental protection, and high safety factor. Traditional Explosive blasting construction technology has been banned in many occasions, or can not be used at all. Especially in complex environments such as modern urban construction and high-speed dangerous rock rescue, the use of explosives for blasting construction has been eliminated. When traditional mechanical crushing is used, strong vibration waves will be generated to cause secondary d...
