Technical Field

The mountain area water supply and irrigation water delivery pipeline often is difficult to avoid laying along the contour lines of the mountain feet or climbing along the ridge, and when the water delivery pipeline climbs along the ridge, the design gradient of the pipeline is usually large, and a series of difficulties such as follow-up construction installation, operation, maintenance and overhaul can be caused.

When a water pipe is paved on a steep slope, a inclined pipe groove needs to be excavated along a ridge, then a formwork is supported in the inclined pipe groove, and concrete is poured to form a concrete pipe foundation. After the concrete pipeline foundation is formed, two measures are generally adopted to install the water pipeline, one is to arrange the water pipeline on the concrete pipeline foundation, then continue to pour concrete on the water pipeline to form a concrete structure fully covering the water pipeline, and fix the water pipeline by using the holding force and friction force of the concrete structure.

According to the measure, after the water pipe is arranged on the concrete pipe foundation, steel bars are arranged on the peripheral surface of the concrete, and then the pipe and the concrete pipe foundation are tightly held by adopting a bolt fastening mode.

The construction of the water conveying pipeline can be completed by fixedly mounting the water conveying pipeline on the concrete pipeline foundation, but the two measures are relatively used for slopes with smaller pipeline slopes (generally, the pipeline slopes are smaller than or equal to 20 percent, and the inclination angle of the pipeline is not larger than 11.31 degrees), when the pipeline slopes are larger, the two measures easily cause aggregate accumulation or slipping in replacement materials or pouring materials due to the influence of gravity when the concrete pipeline foundation is constructed, so that the uniformity and quality of the concrete pipeline foundation construction are difficult to ensure, and the construction process is difficult and the potential safety hazard of the concrete pipeline foundation is caused.
