Temperature: for the solidified mortar layer or concrete component, if the cement pipe factory is often in high temperature and extreme heat conditions, there will be strength loss. This is because the calcium hydroxide in the cement stone will be separated under high temperature conditions. In addition, some aggregates will separate or expand in volume under high temperature conditions. Cement raw materials: when selecting cement, cement varieties with high strength, good durability, appropriate price and reliable quality should be selected. The cement varieties with special properties shall be selected according to the service conditions of cement pipes; It is an important condition to ensure the durability of cement pipes to select better sand and stone aggregates, and sand and stone aggregates with good quality and qualified technical conditions.

4) When mixing and sinking, start the rotary table of the deep mixing pile machine. When the speed of the mixing head is normal, the drill pipe can be mixed while sinking along the guide frame. The sinking speed can be adjusted by the gear, and the working current should not be greater than the rated value. 5) When the grout is mixed and lifted and sunk to the design depth, start the mortar pump, send the grout through the pipeline to the grout outlet of the mixing head, start the mixing pile machine and tighten the chain device after the grout is discharged, and lift the drill pipe while spraying and mixing according to the designed lifting speed (0.50~0.8m/min) to fully mix the grout and soil. 6) Repeat mixing and sinking. After the mixing bit is lifted to 500mm above the pile top, turn off the mortar pump, repeat mixing and sinking to the design depth, and the sinking speed shall be in accordance with the design requirements.

The center of gravity of the lifting object shall be properly selected, and the power generating point of the electric jack shall be effectively selected. The bottom edge must be paved, and the standard of hard and soft pavement shall be fully considered. Whether to pad the tough wood, whether to place it stably, and avoid weight depression or skew. If the residual oil of the pump body is not enough, the pump must be filled with oil during operation before application. The application of electric oil pump must refer to the manual of electric oil pump. In case of use, the requirements in the key main parameters should be followed very well. Do not be overweight. After arriving at the travel arrangement, pressure should be applied. Otherwise, when the height width ratio of lifting or the lifting tonnage exceeds the requirements, the top of the hydraulic cylinder may have serious oil leakage.

1. Centerline setting of pipeline: before construction, the starting point, end point, plane break point, longitudinal break point and straight line control center pile of the centerline can be measured on the site according to the center line control point given in the design, and the direction control pile can be set at the appropriate position outside the groove of the starting point and end plane break point, and the pile number can be determined through measurement. 2. Establish temporary bench marks: temporary bench marks are often required for pipeline works, which should be set at a stable place that is not easy to be collided, and the spacing should not be more than 30 meters. The closure error of temporary benchmark shall meet the specified standards. 3. Trench excavation is mainly conducted by excavator, supplemented by manual bottom cleaning, and the connection pipe and branch pipe of rainwater hopper are excavated manually. During excavation, pay attention to the change of soil quality, and support the sections with signs of collapse.

When it comes to cement pipes, I believe you are no stranger. All kinds of cement pipes are widely used in daily life. However, although the cement pipe is very convenient to use, it also has a certain service life. 1. It is important to choose the type of cement. Only by selecting the type of cement that meets the requirements can the service life be increased. Therefore, the selection of raw material cement is also very critical. The selected cement type must meet the requirements in strength and fineness. Ordinary Portland cement is the best choice, and the setting time should not be too long. 2. Control the water cement ratio and cement consumption.
