Prefabricated assembling type externally pre-stressed anchoring anti-slide pile

Abstract

The invention discloses a prefabricated assembling type externally pre-stressed anchoring anti-slide pile. A pile body of the anchoring anti-slide pile comprises a pile head section, a pile shaft and a pile tip section which are connected in sequence. The pile shaft is formed by connecting a plurality of pile shaft sections of the same structure from top to bottom in sequence. The cross section of each pile shaft section is in an ''I'' shape or hollow rectangular shape. A groove is formed in the top surface of each pile shaft section, and a protruding block is arranged on the bottom surface of each pile shaft section. In two adjacent pile shaft sections, the protruding block of the pile shaft section on the upper portion is embedded in the groove of the pile shaft section on the lower portion. Protruding blocks adaptive to the grooves of the pile shaft sections are arranged on the bottom surface of the pile head section. Grooves adaptive to the protruding blocks of the pile shaft sections are formed in the top surface of the pile tip section. The pile head section and the pile tip section are of an entity structure. The pile head section, the pile shaft and the pile tip section are anchored together through pre-stressed tendons arranged outside the pile shaft. According to the prefabricated assembling type externally pre-stressed anchoring anti-slide pile, factory-like manufacturing is achieved, the anchoring anti-slide pile has the characteristics of modularization, standardization and mass manufacturing, construction difficulties are reduced, and constructing is fast and efficient.

Description

technical field [0001] The invention relates to the field of slope reinforcement, in particular to a prefabricated assembled external prestressed anchor anti-slide pile. Background technique [0002] With the rapid increase of the designed mileage of mountainous railways in our country, a large number of cutting and high slope projects have appeared. Anchored anti-slide piles can reinforce deep and large cuttings and high slopes, so they are widely used in railway subgrade engineering. However, the traditional cast-in-place anchored anti-slide piles are expensive, slow in construction, and difficult to guarantee the quality of the pile body, which does not match the fast and efficient reinforcement requirements of high cutting slopes. Contents of the invention [0003] Aiming at the shortcomings of the existing cast-in-place anti-slide pile construction technology, the invention provides a prefabricated assembled external prestressed anchor anti-slide pile. The use of th...
