1. Xiangyang once had more than 30 slag raking machine factories, which closed down last year. Zhongliang and Shuailong are recommended as the two with the highest quality and cost performance.

The suitable cross section of the tyre scraper is 1.6 * 1.6m; 1.8 * 1.8m; 2 * 2m section
suitable section of rail loader: 80 type 1.8 * 1.8m; 100 type 2.5 * 2.5m; 120 type 2.4 * 2.5m; 150 type, 2.5 * 2.8m; 160 Type 3.2 * 3.2m section. The selection of this model is mainly based on the mechanical equipment used to transport ore [such as rail transport, bucket car transport, shuttle car transport, etc.]
suitable section of crawler excavator loader: 80 type 2 * 2.2m; 100 type 2.6 * 2.6m; 100 type 2.2 * 2.4; 120 type 2.3 * 2.6m; 120 type 2.8 * 2.8; 150 type, 2.5 * 2.9m; 150 type 3.5 * 3.5m; 180 type, 2.8 * 3.3m; 180 type, 3 * 4m; 180 type, 4 * 4m; 200 type 4 * 4m; 220 type 4.5 * 4.5m; 260 type 5 * 5m; 312 type, 5 * 5m; 330 type 5 * 5m section
suitable section for inclined shaft with large slope: 80 crawler type 2.4 * 2.5m section with maximum working slope of 30 degrees; The maximum working gradient of 100 crawler type 2.6 * 2.6m section is 25 degrees; 120 crawler type 2.4 * 2.4m, maximum working gradient 28 degrees; 150 crawler type 3.5 * 3.5m, maximum working gradient 28 degrees; The maximum working gradient of 4 * 4m section of 180 crawler type is 32 degrees; 120 crawler type 2.8 * 2.8m, maximum working gradient 32 degrees; The maximum working gradient of 312 crawler type 5 * 5m section is 30 degrees
the main equipment commonly used in the construction of large section or full section are as follows:
rail transportation: gantry drilling jumbo, bolt support, vertical claw or rake bucket rail type rock loader (slag loader), 10 ~ 30 cubic shuttle mine car or mining big bucket car, 12 ton or 25t traction motor car, concrete spraying machine or transport pump, steel formwork jumbo combined supporting construction
trackless transportation: 3-arm or 4-arm tire and crawler electric hydraulic rock drilling jumbo, shotcrete anchor support, anchor jumbo, bucket crawler loader, 20 ~ 25 ton mining truck or pit truck [small secondary wheel and small Dongfeng], concrete spraying machine or delivery pump, integral steel formwork jumbo
the advantages of trackless shipping are high proction efficiency, good mobility, overcoming the practical advantages of working with large slope, small turning radius, strong working force, fast speed, not subject to conditions and so on. Although the initial investment is relatively high, the construction cost is low and fast, the engineering quality is good, and the safety and environmental protection are constantly improving. It is a common construction method in underground construction

3. Excavation of 4 M 8 by 4 m diversion tunnel: 56 yuan per meter, including materials

4. The 7x7 diversion tunnel needs small excavators
small: under 15t is small, and 5 ~ 8t is the main type. Operation for municipal, trenching, construction in the plant, garden and other projects need small operation.

5. The hole is small, the structure is simple, the cycle period is short, the included angle is too small, the resection is not easy to use, the others are the same.

6. The tunnel in which the water flow fills the whole section is called pressure tunnel. When the water flow in the tunnel has a free surface, it is called a non pressure tunnel. There are great differences between pressure tunnel and non pressure tunnel in engineering layout, hydraulic calculation, stress and operation conditions. For reservoirs with large drawdown depth, pressure tunnel is generally used. In the face of Low Head Intake Dam or reservoir with small drawdown depth, non pressure tunnel is generally used for water diversion. Sometimes, it can be designed with or without pressure, which needs to be determined after technical and economic comparison.

7. You said this situation in the instrial and commercial law, as long as injured at work, then he belongs to instrial injury, according to you said this situation is definitely belong to instrial injury behavior.

8. Constructor of water conservancy and Hydropower Engineering

10. Well, it's ok as long as it's introced in the form of a guide. It's actually quite simple. Well, I wrote a lot about it~~
