Hydraulic fracturing is we often used in the construction, we will often see its shadow, then the equipment such as hydraulic fracturing device, when in use, is what specific actions it? Next, we will look at it together. Hydraulic fracturing consists of two major pumping stations and splitting machine components, high-pressure oil pump station output driven operating cylinder, a huge thrust, driving the wedge in the middle of the wedge group project forward, reverse wedge distraction to both sides can be split so that the object split. Hydraulic fracturing is the specific implementation steps are as follows: First, the object to be split drill a specific diameter and depth of the hole, the hydraulic splitting the wedge set (an intermediate wedge and two reverse wedge) into the hole , the intermediate pressure hydraulic wedge action between the two counter-wedge forward movement, is released from the inside out has shown great energy, an object to be split split in a predetermined direction within a few seconds. Any object has its own characteristics, rock and concrete with high external compressive strength, tensile strength from the inside out is very small, the compressive and tensile strength is 100: The difference of 2 to 10, in a brittle state. Hydraulic fracturing is caught brittle rocks and concrete features, the use of wedge design principle - in the most narrow bore outward to release a great deal of division force.
