Concrete conveying process for high steep and big drop height landform

Abstract

The invention relates to a concrete delivering method in the high-slope and big-drop terrain. The method comprises the following steps: the parameters of the length, the elevation, the slope angle and the scar property of the horizontal section of a concrete placement area are comprehensively mastered through field terrain investigation; concrete is horizontally delivered through a conveyer belt; when the slope angle is larger than 40 degrees and smaller than 53 degrees, the delivering is realized through a negative pressure sliding chute; when the slope angle is larger than 53 degrees and smaller than 90 degrees, the delivering is realized through the combination of a sliding cylinder and a slowly decreasing and mixing machine. The method effectively combines the economic and practical delivering means according to local conditions, and the concrete delivering purpose is achieved, thereby, under the precondition of ensuring the concrete delivering quality, the cost is reduced further. The method is particularly applicable to the high-slope and big-drop concrete delivering in valley and mountain under the limited field and road conditions.

Description

technical field [0001] The invention relates to a concrete conveying method, in particular to a concrete conveying method for high steep slope and large drop terrain. Background technique [0002] For the transportation of concrete in the hydropower industry (such as the transportation of concrete in dams and hydropower stations), especially vertical transportation, the traditional methods mainly use cable conveyors or tower crane tanks, or use Rotek belt conveyors (that is, use tower crane belt conveyors to distribute materials) ). The common disadvantages of these traditional methods are equipment layout, long construction period, high construction cost, and strict restrictions on the construction site. Concrete engineering construction is often carried out in high mountains and valleys, where the construction site is limited, the roads are narrow, the amount of concrete conveyed is large, and the construction period is tight.

The common disadvantages of these traditional methods are equipment layout, long construction period, high construction cost, and strict restrictions on the construction site.

Concrete engineering construction is often carried out in high mountains and valleys, where the construction site is limited, the roads are narrow, the amount of concrete conveyed is large, and the construction period is tight. Especially for RCC projects that require rapid construction and high-intensity conveyance, traditional methods are often difficult to meet the actual needs of construction.
