Pre-tensioning prestressed concrete porous hollow ecological pile and construction method thereof

Abstract

The invention relates to a pre-tensioning prestressed concrete porous hollow ecological pile and a construction method thereof. The pre-tensioning prestressed concrete porous hollow ecological pile is characterized by comprising a pile body with a rectangular section as well as a tenon and a mortise trough which are connected and are correspondingly arranged at the sides of two short sides of the pile body; at least one hollow hole is longitudinally formed in the pile body; and an ecological through hole communicating with the hollow hole is formed in the side of the long side of the pile body. The pre-tensioning prestressed concrete porous hollow ecological pile has the advantages that the favorable bending resistance required in the supporting engineering is realized by a section way and a stress way; and due to the adoption of a grouting groove, the on-site construction is high in operability, the assembly degrees of members and the operation efficiency are high, the structural integrality and the construction quality can be guaranteed, the construction cost can be reduced, the construction effect of the engineering is good, the soil retaining and water stopping functions are achieved, and the existing defence pile wall structure can be replaced. In addition, the water power relationship between a water body and a soil body at the bank side is guaranteed, the flowability of nutrients and energy is favorably realized, and a bank protection member plays roles in retaining a slope and keeping the balance of an ecological environment.

Description

[0001] Technical field: [0002] The invention relates to concrete products used in civil engineering, traffic engineering, water conservancy engineering and other fields, in particular to a pretensioned prestressed concrete porous hollow ecological pile and a working method thereof. [0003] Background technique: [0004] In the field of civil engineering, there are many forms of building support structures currently used. Commonly used permanent retaining support structures include: cast-in-place underground diaphragm wall, gravity reinforced concrete retaining wall, cast-in-place bored pile, steel sheet pile And concrete sheet piles, etc., as well as traditional mortar block stone and dry block stone structures. Most of the traditional support structures adopt the method of cast-in-place, which has long construction period, low work efficiency, high engineering cost, and complicated construction procedures. Moreover, the durability of mortar block stone and dry block stone...

AI Technical Summary

Problems solved by technology

However, the flexural performance of traditional concrete sheet piles is limited by materials and structures, and after the construction is completed, the sheet piles form a sealed continuous wall structure, which seriously hinders the penetration of water and cuts off the slope and the slope. The flow of water, nutrients and energy in the river is not conducive to the ecological balance of the aquatic environment
