Abstract

The invention discloses a cement mortar grouting tank for prestress long anchor rope grouting and an application method. A tank body (1) is mounted on a bracket (2); a bottom outlet of the tank body (1) is connected with a mortar outlet pipe (3); an air intake pipe (4) and an exhaust pipe (10) are arranged at the upper side of the tank body (1); a control quick valve (5) is arranged on the air intake pipe (4); a safety valve (6) is arranged on the exhaust pipe (10); a pressure cover plate (8) is arranged in an upper opening of the tank body (1); a sealing ring (7) is added below the pressure cover plate (8); and the pressure cover plate (8) and the sealing ring (7) are fixed on the edge of the upper opening of the tank body (1) through fastening bolts (9). The cement mortar grouting tank is changed from an industrial oxygen bottle, adopts an air pressure type working principle to perform the all-angle deep hole grouting of cement mortar, is full in grouting, quick in speed, easy to operate, simple in equipment configuration, easy to be maintained and convenient for use, can realize the all-angle deep hole grouting, and in particular, is suitable for use under environments of complicated terrains or narrow spaces.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a small grouting tank and a method for using the same, in particular to a prestressed long anchor cable, a bolt pressure grouting tank and a The method of use is suitable for use in complex terrain conditions in the field. Background technique [0002] Prestressed long anchor cables (bolts) are generally used in slope reinforcement and roadway surrounding rock reinforcement, and are characterized by drilling depth (8-30m), small hole diameter (45-130mm), and the drilling angle can reach 360° Scope; In the construction quality control of long anchor cables (bolts), an important node is the tank quality of the anchor grout. According to the construction operation essentials, the grouting must be full according to the requirements of the construction process. During grouting, the grouting pipe should be inserted to the bottom of the hole and slowly pull...
