High-pressure grouting device for bridge bottom reinforcement in high temperature environment

Abstract

The invention relates to the technical field of bridge maintenance, and discloses a high-pressure grouting device for bridge bottom reinforcement under high temperature environment, Including groutingchamber, Slurry inlet pipe, slurry guide pipe, casing, surge chamber, breathable diaphragm, pressure regulator, Two cooling mechanisms, a metering chamber, a slurry outlet pipe and a circulation hole, wherein the slurry inlet pipe is fixedly communicated with the left end of the slurry injection chamber, the slurry guide pipe is fixedly communicated with the right end of the slurry injection chamber, the sleeve is fixedly sleeved on the outer surface of the slurry inlet pipe, the surge chamber is fixedly sleeved on the outer surface of the sleeve and the slurry guide pipe, and the air permeable diaphragm is fixed on the middle of the top wall of the slurry injection chamber. The air pressure in the grouting chamber can be dredged from the two exhaust holes, the air intensity difference inside and outside the grouting chamber can be reduced, the grouting chamber can be prevented from cracking due to the larger pressure difference, the airflow flow rate between the grouting chamber andthe surge chamber can be accelerated, the temperature on the outer surface of the grouting chamber can be rapidly evaporated, and the effect of lowering the temperature of the grouting chamber can beachieved.

Description

technical field [0001] The invention relates to the technical field of bridge maintenance, in particular to a high-pressure grouting equipment for reinforcing the bottom of a bridge in a high-temperature environment. Background technique [0002] When the car passes over the bridge, it will cause the road surface of the bridge to vibrate. In the hot summer, thermal expansion and contraction will cause cracks at the bottom of the bridge. Therefore, it is necessary to reinforce the bottom of the bridge and use high-pressure grouting equipment Repair the cracks that appear. However, when the traditional high-pressure grouting equipment is used in a high-temperature environment, there will be a large difference in the internal and external pressure of the grouting equipment due to the high temperature. The large pressure difference will cause the grouting pipe to burst. Thus affecting the effect of bridge reinforcement, for this reason, we propose a high-pressure grouting equipm...

[0002] When the car passes over the bridge, it will cause the road surface of the bridge to vibrate. In the hot summer, thermal expansion and contraction will cause cracks at the bottom of the bridge. For this reason, the bottom of the bridge needs to be reinforced, using high-pressure grouting equipment Repair the cracks that appear. However, when the traditional high-pressure grouting equipment is used in a high-temperature environment, there will be a large difference in the internal and external pressure of the grouting equipment due to the high temperature. The large pressure difference will cause the grouting pipe to burst. Thus affecting the effect of bridge reinforcement, for this reason, we propose a high-pressure grouting equipment for bridge bottom reinforcement under high temperature environment
