Automatic control device for concrete elevation pouring and control method for concrete elevation pouring

Abstract

The invention discloses an automatic control device for concrete elevation pouring and a control method for concrete elevation pouring. The automatic control device for concrete elevation pouring canrealize full-automatic concrete pouring work in combination with the control method and can realize concrete surface positioning within a certain height range of a designed elevation; a depth sensor is arranged at a measuring position within a certain height range to detect the height of a concrete surface at the measuring position, and the accuracy is improved under the assistance of a main sensor; and in addition, the depth sensor is used for combining the height of the concrete surface with the amount of poured concrete in the measuring position, so that the pump output of the concrete begins to be gradually reduced when the concrete surface reaches a preset target position; and the pump output of the concrete of a flow control valve is reduced to the minimum when the concrete surface reaches the elevation position and pouring is stopped, a pump outlet of a concrete supply device can be closed immediately, and over-pouring is avoided.

Description

technical field [0001] The invention relates to the technical field of basic construction engineering, in particular to an automatic control device and a control method for concrete elevation pouring. Background technique [0002] Cast-in-situ piles are formed by directly opening a circular hole with a cross-section on the designed pile position. After the hole is formed, a steel cage is added in the hole and concrete is poured. With the vigorous development of engineering construction in my country, the cast-in-place pile foundation project is It is widely used in large-scale projects such as high-rise buildings, bridges, port terminals, offshore oil production platforms, and nuclear power plants, but the elevation control of concrete pouring piles has always been one of the difficulties in the construction of concrete pouring piles. In the following positions, it is impossible to directly obtain the concrete pouring height in real time. In actual engineering, we can only rel...
