Prefabricated drainage prestressed anti-slide pile structure and construction process thereof

Abstract

The invention discloses a prefabricated drainage prestressed anti-slide pile structure and a construction process thereof. The anti-slide pile structure comprises pipe piles, and the pipe piles comprise the I type steel concrete pipe pile, the II type steel concrete pipe pile and the III type steel concrete pipe pile which are sequentially connected, a tip plate is arranged at the bottom of the Itype steel concrete pipe pile, a connecting end disc is arranged at the upper end of the I type steel concrete pipe pile, the lower end of the II type steel concrete pipe pile is provided with a threaded end disc, the upper end of the II type steel concrete pipe pile is provided with a connecting end disc, the top of the III type steel concrete pipe pile is provided with a tip plate, the lower endof the III type steel concrete pipe pile is provided with a threaded end disc, and every two adjacent pipe piles are connected through the corresponding connecting end disc to the corresponding threaded end disc. The prefabricated drainage prestressed anti-slide pile structure and the construction process are applicable to a landslide disaster rapid treatment project or an emergency rescue project which is in progressive damage or accelerated damage state, have the characteristics of the short construction period, simple and convenient construction, small economic input, large landslide loads, drainage capacity and the like, and have the disaster prevention, disaster mitigation and emergency rescue attributes.

Description

technical field [0001] The invention relates to a prefabricated drainage prestressed anti-slide pile structure for fast landslide control and its construction technology, which belongs to the landslide prevention and disease structure of mountainous roads, railways, urban pedestrian passages, reservoir banks, infrastructure and other transportation, water conservancy, and construction projects reinforcement field. Background technique [0002] Anti-slide piles are piles that pass through the landslide body and go deep into the slide bed. They are used to support the sliding force of the slide body and stabilize the slope. They are suitable for shallow and medium-thick landslides and are the main anti-slide treatment. measure. It has the advantages of convenient construction, safety and reliability, can withstand large thrust, and can save a lot of masonry. Anti-slide piles were first used in the United States in the 1930s, introduced into China in the 1950s, and widely use...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above that the existing anti-slide pile structure is not suitable for landslide disasters that are in gradual damage or accelerated damage.
