Cement grouting machine for maintenance

Abstract

The invention discloses a cement grouting machine for maintenance. The cement grouting machine comprises a fixing frame, rolling wheels are arranged at the four corners at the bottom of the fixing frame, and an electric control box is fixed to the surface wall of one side of the fixing frame; a pushing hand is welded to the position, located above the electric control box, of the fixing frame, aninstalling inclined plate is welded to the fixing frame, and a discharging pipe is fixed to the installing inclined plate; a material drum is fixed to the discharging pipe through a sleeve, a discharging motor is fixed to the position, located at the top end of the discharging pipe, of the installing inclined plate, and the discharging motor is in transmission connection with a spiral conveying rod in the discharging pipe through a speed reducer; and the discharging pipe is connected with a grouting nozzle through a high-pressure pipe. According to the cement grouting machine for maintenance,through the arrangement of a flow control valve, the quantity of flow of grouted cement paste through the grouting nozzle can be controlled according to the size of a grouting crack, and overflow waste of the cement paste caused by the too-high quantity of flow is prevented; and the cement grouting machine is reasonable in design and convenient to control and use.

Description

technical field [0001] The invention relates to the technical field of cement grouting machines, in particular to a cement grouting machine for maintenance. Background technique [0002] At present, with the rapid development of the construction industry, architects pay more attention to the deformation of expansion joints in building structures than ever before. The rise and fall of temperature caused by thermal expansion and contraction, the rise and fall of the foundation, the shaking of the top of high-rise buildings, earthquakes, etc., all cause The expansion joint deformation of the building. For this reason, the research and development personnel have studied the above problems in depth, combined with the actual situation, fully considered the careful development, and absorbed the advanced design concepts and experience of foreign countries in this field, so the cement mortar spraying grouting machine came into being. The cement mortar spraying grouting machine is sui...

Problems solved by technology

[0003] Yet the existing cement grouting machine that is used for maintenance has some deficiencies in the use process, and the feeding pipe is mostly a horizontal structure, and the screw feeding rod is not provided inside, resulting in very stable feeding. The grout nozzle is not equipped with a flow control valve, and the grouting flow cannot be controlled according to the size of the crack, which may easily lead to overflow and waste of grout
