The invention discloses a slide valve for vertical slide conveying of concrete. The slide valve comprises a feeding pipe, a tank body, a buffer funnel and a discharging pipe which are sequentially communicated from top to bottom, a lower sealing cavity is formed in the position, corresponding to the buffer funnel, of the outer side wall of the tank body, and a telescopic rod and a drawing and inserting sealing plate are arranged in the lower sealing cavity; and one end of the telescopic rod is fixed in the lower sealing cavity, the other end of the telescopic rod is fixedly connected with one end of the drawing and inserting sealing plate, the other end of the drawing and inserting sealing plate can extend into the discharging pipe and seal the discharging pipe, and the whole drawing and inserting sealing plate can be driven by the telescopic rod to reciprocate in the length direction of the drawing and inserting sealing plate. The slide valve can realize continuous downward transportation of the concrete, is mainly suitable for continuous transportation of the concrete in a vertical shaft and an inclined shaft with the inclination larger than 60 degrees, and has the advantages of high efficiency, high speed, good continuity and no separation in concrete slide conveying compared with a traditional hanging tank warehousing manner, so that the pouring quality is obviously improved, the time required by building construction is shortened, and the working efficiency of workers is greatly improved.
Description
technical field [0001] The invention relates to the field of concrete transportation, in particular to a slide valve for vertical concrete delivery. Background technique [0002] With the continuous development of economy, society and construction technology, there are more and more super high-rise and super deep foundation pit projects. In the construction of such construction projects, the construction of mass concrete for the foundation floor is an important construction link. In the construction of large-volume concrete pouring in foundation pits, segmentally connected slide pipes are often used as pouring pipes. Generally, the slide pipes are at a certain angle to the horizontal plane and supported by steel brackets. In order to ensure the coverage of the concrete when pouring large-volume concrete, it is usually necessary to install branch pipes at the rigid support. In order to control the flow direction conversion of the slide pipe, the current conventional method is...
