Mixed grouting machine used for tunnel construction and capable of removing concrete gas through choking pressing

Abstract

The invention discloses a mixed grouting machine used for tunnel construction and capable of removing concrete gas through choking pressing. The structure of the mixed grouting machine comprises an output pipe, a movable mixing device, an input pipe, a bearing seat and a pneumatic frame, the bearing seat is arranged on the upper side end surface of the movable mixing device and is fixedly connected with the movable mixing device, the internal concrete is pressed to descend through the pressing of an internal pressing frame; then concrete extrudes an opening and closing frame, meanwhile, choking and pressure division are performed through the opening and closing frame, internal air bubbles are exploded, then outputting is performed, meanwhile, water is injected through a water pipe below, therefore gas in an internal clamping block is extruded out, meanwhile, after an inclined column is clamped, internal water flow is output through a mounting frame, adjustment is conducted through theinclined column, electromagnetic adsorption is conducted after descending, moisture left through the inclined structure humidifies the entering concrete, and excessive drying of the concrete is prevented.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a hybrid grouting machine for tunnel construction that removes concrete gas through blocking and pressing. Background technique [0002] The grouting machine usually inputs various raw materials and performs high-speed rotation and stirring through the internal stirring device, so that the internal raw materials are mixed with water to form concrete, and the grouting is completed by negative pressure suction. But in this way: [0003] When performing grouting work, when the mixed raw materials are processed by high-speed agitation, because the internal liquid rotates at a high speed during stirring, the gas is in high-area contact, which increases the gas inside the concrete, which leads to the filling. Excessive internal gas causes the appearance of air bubbles and cavities inside the filling, which affects the filling effect, and when the mixing is output, the moisture loss ...

AI Technical Summary

Problems solved by technology

[0003] During the grouting work, when the mixed raw materials are processed by high-speed agitation, because the internal liquid rotates at a high speed during the agitation, the gas is in high-area contact, which increases the gas inside the concrete, which leads to the filling. The appearance of air bubbles and cavities inside the filling caused by excessive internal gas affects the filling effect, and when the mixing is output, the internal concrete loses too much moisture, resulting in difficulty in filling and premature condensation
