Introduction of piston rock splitter equipment:
The piston rock splitter equipment consists of two parts: the hydraulic pump station and the splitter. The working principle of the splitting machine is that the ultra high pressure oil driven cylinder output from the pumping station has a great driving force and can be made by the mechanical magnification Direction cracked.

Concrete application of piston rock splitter equipment in tunnel excavation
1. Rock crusher dismantling during tunnel excavation
As we all know, during the excavation and construction of the tunnel, the dismantling of the hydraulic rock splitter has always been carried out as a very important project. Before the artificial construction of the tunnel, the first thing we must do is to dismantle the rock and rock splitting machine in the rock. The demolition process has a very important role. With the continuous development of science and technology, the application of hydraulic rock splitters is becoming more and more extensive. In the tunnel mining process, first of all, the rock that is integrated with the mountain body should be gradually split from the mountain, and then the split rock should be transported out of the tunnel to gradually form the construction space. In the tunnel excavation and construction process, we need to effectively analyze the rock structures that have been demolished, and come up with a reasonable splitting plan. For example, according to the structure and force of the rock, we will use the hydraulic rock splitter to disassemble it first. Which part of the site is to be removed later, so as to avoid the occurrence of landslides, rock fall, etc. during the rock removal process. The use of hydraulic rock splitters to dismantle the rock that is integrated with the mountain body has high directionality and demolition accuracy. According to the pre-designed excavation scheme for tunnels, reasonable use of hydraulic rock splitters for rock removal can not only achieve good demolition results. , And it is conducive to the implementation of the entire construction project, which not only achieves the purpose of accurate crushing, but also effectively reduces the production cost and improves the economic efficiency of the construction team.
2. During the excavation process of the tunnel, the secondary crushing of rocks by rock splitters
As mentioned earlier, although there are currently advanced hydraulic rock splitters, the previously used explosives can not be abandoned completely. In the course of tunnel excavation and construction using explosives, it will inevitably result in the formation of bodies. And the larger rock, this rock has been split from the mountain, but due to the construction space, etc., it is impossible to smoothly transport the split whole rock out of the tunnel. At this time, the rock splitting machine needs to split it. This type of rock undergoes secondary crushing. We know that for rock, in general, its compressive strength is relatively large, but its tensile strength is relatively small. According to surveys, the ratio of compressive strength and tensile strength of rock is approximately About 10:3, the rock splitter is designed based on this mechanical property. The hydraulic rock splitter consists of two parts: one is a hydraulic pump that provides power, and the other is a split gun that is used for rock breaking. During the working process, the hydraulic pump transmits the super high pressure oil pressure generated by the transmission system to the split gun, and the split gun advances under the mechanical action. In the process of advancement, the wedge in the middle of the split gun will be opened on both sides. Under the action of this mechanical movement, the split and heavy rock will be effectively split. According to device size
Different from the power, different rock splitters produce different splitting forces. In the general tunneling process, the rock splitting gun can produce more than 600 tons of splitting force under the action of a hydraulic pump. It is enough to cut and split the rock of the general structure.
3. Splitting and dismantling of the reinforced concrete structure of the tunnel during tunnel excavation
We know that in the process of tunnel excavation and construction, reinforced concrete structures are often used as a kind of civil structure, while tunnels made of reinforced concrete are only relying on artificial forces in the process of later improvement and construction. It is impossible to meet the construction needs. For example, we need to reconstruct the already-constructed tunnel concrete structure and use the traditional manual method to dismantle the original concrete structure. The work efficiency is very low and cannot meet normal work. Progress and nodal points, this time requires the use of rock splitters to effectively demolish the concrete structure. We know that ordinary rock splitters can produce more than 600 tons of splitting force instantaneously, so the use of hydraulic rock splitters to carry out the tunnel in the concrete The demolition and reconstruction of the structure has a very important role. Especially for concrete structures that require local reconstruction, if the concrete is split by means of an explosive demolition scheme, the degree of fragmentation cannot be grasped, and the surrounding rocks and concrete structures that do not need to be classified will be destroyed to varying degrees. This will cause serious construction quality problems in the entire tunnel project, leaving great potential safety hazards for future tunnel operations. The use of rock splitters for local reinforced concrete demolition can effectively avoid this, and the use of rock splitters for demolition can precisely split the concrete structure and ensure that the surrounding rock or concrete structure will not be affected. Its split accuracy.
