AI Technical Summary

Technical Problem

Existing concrete chute structures have limited coverage area on slopes, involve numerous construction procedures, and are inefficient, making it impossible to efficiently pour concrete on slopes.

Method used

Design a concrete funnel chute device, including a conical hopper and multiple concrete chutes connected by joint pipes. Concrete is synchronously delivered to each chute through the conical hopper, covering a large area of ​​slope, and the flow rate is controlled by adjusting the chute angle to achieve uniform distribution.

Benefits of technology

It enables construction coverage of large-area slopes, simplifies the stability and efficiency of traditional chute structures, improves construction efficiency and quality, and ensures concrete uniformity and construction quality by adjusting the chute angle and pipe diameter to control the concrete flow rate.

Abstract

A concrete funnel elephant trunk device comprises a support and a conical hopper, the support is integrally a square frame body, the frame body comprises a seat plate and a platform plate which are arranged in parallel, supporting legs are arranged among the four corners of the seat plate and the four corners of the platform plate, the conical hopper is placed on the platform plate, and a cylindrical discharging pipe is arranged at the lower end of the conical hopper. A lower port of the discharging pipe is sealed through a bottom plate, connector pipes are arranged at the front end and the two sides of the discharging pipe in the radial direction, the outer ends of the connector pipes are connected with concrete articulated chutes, and the concrete articulated chutes are arranged downwards in an inclined mode; according to the articulated chute device, the plurality of joint pipes are arranged at the discharge port at the lower end of the conical hopper, the plurality of concrete articulated chutes can be simultaneously connected to the plurality of joint pipes, the concrete articulated chutes can cover a larger slope area at one time, and concrete can be synchronously conveyed to each concrete articulated chute through the conical hopper; the problems that a traditional chute structure is small in coverage area and needs to move frequently are effectively solved, the slope concrete construction efficiency is improved, and the construction cost is reduced.
