Abstract

The invention discloses grouting equipment for constructing an impervious curtain of a dam. The grouting equipment comprises a mixing box, wherein a mixing cavity opened downward is formed in the mixing box, a quantifying device is arranged in the mixing cavity, an opening device located on the front side of the quantifying device and controlled by the quantifying device is arranged in the mixingcavity, a mixing device located on the lower side of the quantifying device for stirring concrete is arranged in the mixing cavity, a power device located on the left side of the mixing device and located out of the end surface of the left side of the mixing cavity partially is arranged in the mixing cavity, and a pressurizing device is arranged on the end surface of the lower side of the mixing cavity. A quantative inputting device can set different inputting proportions by adjusting the resistance of a damper and is easy to fit different operating demands. A twin-screw stirring device can stir and mix raw materials quickly, and then concrete is poured into a construction station by a pressure conveying device, so that concrete is stirred and poured automatically in a construction site.

Description

technical field [0001] The invention relates to the technical field of embankment grouting, in particular to a grouting device used for the construction of embankment anti-seepage curtains. Background technique [0002] Curtain grouting is a grouting project that pours grout into the cracks and pores of the rock mass or soil layer to form a continuous water-blocking curtain to reduce seepage and seepage pressure. Curtain grouting is used in rock or gravel foundations of dams The construction of anti-seepage curtain by grouting. The top of the curtain is connected with the concrete gate floor or the dam body, and the bottom of the curtain is penetrated to a certain depth in the relatively impermeable rock layer to prevent or reduce the penetration of groundwater in the foundation. It can also work together with the drainage system located downstream. To reduce the uplift pressure of seepage water flow on the dam, the concrete used in the current curtain grouting is usually pr...
