Embodiment

[0027] Such as figure 1 , figure 2 Among them, a concrete vertical conveying system for small and medium-sized hydropower stations with high and steep slopes. Due to the complex terrain in the actual situation, a combination of various conveying methods is used. In this case, the drop reaches 150m.

[0028] 1), the whole system is composed of a belt conveying section 1, a chute conveying section 2, a chute conveying section 3 and a column chute conveying section 4, and each conveying section is connected by a hopper 12, a crutch 13 or a collecting hopper 14;

[0029] 2), the belt conveyor section 1 is erected on a slope below 40°, the chute conveyor section 2 is erected on a gentle slope of 40°-55°, the column chute conveyor section 4 is erected on a variable slope of 40°-55°, and the column chute conveyor section is erected on a slope of 56°-89° Conveyor section 3 for slope erection chute;

[0030] 3), the maximum permissible drop of the single-stage conveying section comp...

Abstract

The invention discloses a vertical concrete conveying system of a small and medium hydropower station at high steep slopes, relating to a concrete conveying system. Through flexibly combining a belt conveying section, a chute conveying section, a chute barrel conveying section and an upright post chute conveying section, the concrete conveying system solves the problems of concrete conveying under the environment of large angles, great head drops and high steep slopes, and is in particular suitable for a concrete conveying task of a project in high-mountain gorge zones. Through improvement onthe technology of the conventional concrete vertical conveying, the concrete vertical conveying system saves the materials, shortens the construction periods, reduces the construction difficulty and ensures the construction security.

Description

technical field [0001] The invention relates to a concrete conveying system, in particular to a concrete vertical conveying system for small and medium-sized hydropower stations with high and steep slopes. Background technique [0002] When building dams or other projects in high mountains and valleys, due to terrain conditions, the use of cable cranes or tower cranes and vehicles to directly enter the warehouse, there are problems such as difficulty, a large amount of equipment to be invested, and a large amount of civil engineering, resulting in high construction costs. or unable to carry out construction. Chinese patent 200810048726.7 discloses "a method of conveying concrete on high and steep slopes and large drop terrain", which adopts a downward transportation system of concrete by its own weight in the environment of large angle, large drop, and high and steep slopes. This method combines negative pressure chute and foreign MY-BOX The successful technology can not on...
