Automatic grouting device and method for joints of precast slabs of side slope catchwater

Abstract

Two ends of a circular plastic pipe of the automatic grouting device are closed and fixed on a frame, circular holes with the same aperture are uniformly distributed in the lower side of the circular plastic pipe, and the circle centers of the circular holes are positioned on the same straight line; the plastic pipe is horizontally or vertically adjusted and fixed through the nut, the scale used for distance measurement is perpendicular to the ground and installed on the outer side of the vehicle frame, so that the plastic pipe is higher than the surface of the intercepting ditch, the clamping groove is used for vertically moving and fixing the plastic pipe, the horizontal nut is used for keeping the plastic pipe at the horizontal position, and the vertical nut is used for achieving angle rotation and fixing of the plastic pipe. Grouting is conducted on joints of the precast slabs of the inclined catchwater; a material box internally provided with stirring blades driven by a motor is used for storing a mixture for grouting, the real-time uniformity of the mixture is guaranteed, and a discharging opening is connected with a guide pipe so that grout can enter a plastic pipe. The side slope intercepting ditch precast slab joint automatic grouting device is simple in structure, convenient to operate, suitable for various precast slab joints, stable in joint grouting effect and long in service life.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to an automatic grouting device for joints of prefabricated slabs of slope intercepting ditches. Background technique [0002] The quality of the cut-off ditch project on the side slope of the subgrade is directly related to the long-term stability of the subgrade. If the joint position is not done well, it will directly cause rainwater to enter the slope soil, resulting in a decrease in the safety factor of the side slope. The existing subgrade construction specifications require joint injection The grout is uniform, full, dense and beautiful, but at present, the joint grouting mainly relies on manpower to fill it with a shovel, the density is not easy to control, and there are problems such as poor fullness and unevenness. [0003] The automatic grouting device for the prefabricated slab joints of the slope intercepting ditch is an automatic filling device for...
