Cutting and polishing integrated device for standard test block of stratified soft rock and use method

Abstract

The invention discloses a cutting and polishing integrated device for a standard test block of stratified soft rock and a use method, and relates to the technical field of mechanical test devices forstratified soft rock. The cutting and polishing integrated device comprises a base, a mobile cutting mechanism, a horizontal polishing mechanism and a rotating disc mechanism, wherein the base is arranged on the first layer, the mobile cutting mechanism and the horizontal polishing mechanism are arranged on the second layer, and the rotating disc mechanism is arranged on the third layer; the baseis provided with an oil pressure device and supporting columns for supporting a mobile platform on the second layer; and the mobile platform is provided with a baffle and a baffle insertion groove forclamping and fixing the rock test block on the mobile platform, and the mobile platform is provided with preformed holes for installing polishing rods to polish and cut the rock test block into a rock test block of a cylindrical structure in cooperation with the rotating disc mechanism. By means of the technical scheme, the technical problem that it is very difficult to make an existing mechanical test standard test block of stratified soft rock can be effectively solved, the standard rock test block of the stratified soft rock can be efficiently made, the surface smoothness is guaranteed while the cutting speed is increased, and meanwhile, the making accuracy and the making efficiency are improved.

Description

technical field [0001] The present invention relates to the technical field of layered soft rock mechanics test device, and more specifically, relates to an integrated device for cutting and grinding a standard test block of layered soft rock and a method of use thereof. Background technique [0002] As our country has invested a lot of money in infrastructure construction such as transportation, especially railway construction; but the development of railway inevitably has the problem of tunnel construction, and because of the complex terrain and geological changes in our country, this makes tunnel construction face many challenges. There are endless new problems; for example, there are many mountains in the southwest of my country. With the construction of tunnels, soft rocks will inevitably be encountered. Soft rock generally refers to a rock mass with weak rock quality, low bearing capacity, well-developed joints and fissures, and broken structure; if the tunnel passes th...

Problems solved by technology

[0004] However, the current method for preparing standard test blocks mainly has the following technical problems: on the one hand, core drilling machines are used to drill core samples and then polished or collected rock blocks on the face of the drill, and then transported to the laboratory for cutting to obtain standard test blocks. However, the thickness of layered soft rock is relatively thin, and it is extremely easy to break and be easily disturbed. Therefore, when core sampling is used to collect rock samples, it is very difficult to fix the corer on the uneven and thin-layered rock surface, so it is difficult to collect Obtain rock samples with sufficient thickness and sufficient length; on the other hand, it is difficult to fix the rock samples when making rock samples, and the degree of disturbance to the rock blocks by cutting machines is very large, and the layered soft rock blocks are easily damaged and difficult to form , so the main reason why it is difficult to obtain rock test blocks and physical and mechanical parameters of rock mass is that it is difficult to obtain standard test blocks; and because rock test block mechanical tests often require multiple sets of test devices, the efficiency of ordinary mechanical methods is often extremely low , it is difficult to meet the requirements of the specification
