Abstract

The invention discloses a fishbone-shaped string barrel suitable for deep foundation pit concrete warehousing pouring. The fishbone-shaped string barrel comprises multiple sections of string barrel bodies which are sequentially connected end-to-end into a whole. A plurality of groups of fishbone-shaped sliding grooves are formed in the inner wall of each section of the string barrel body in the form of spiral extending at intervals. Each fishbone-shaped sliding groove is of a streamline form space curved surface structure and extends downwards. The fishbone-shaped string barrel can comprehensively adapt to foundation pit environmental conditions such as narrow, high and steep, deep and narrow foundation pits. The fishbone-shaped string barrel is simple in structure, low in cost and rapid in construction.

Description

technical field

[0001] The invention belongs to the technical fields of water conservancy and hydropower engineering, water supply engineering, etc., and more specifically relates to a fishbone string structure suitable for pouring concrete in deep foundation pits, and is especially suitable for pouring concrete into silos for foundation pits such as narrow, high and steep, and deep and narrow. Poured new structures. Background technique

[0002] In water conservancy and hydropower projects, the construction site is narrow such as tunnels, hidden culverts, etc., high and steep such as pile foundations, pipe columns, etc., and deep and narrow such as vertical side walls. Due to the constraints of these boundary conditions, the method of pumping concrete into the warehouse has to be used. Completed, in this kind of large drop foundation pit, the steel bars are dense, and the pumping of concrete into the warehouse increases a lot of difficulties, which will cause concrete segre...
