Inorganic material pressurization grouter used for mending concrete hole and seam

Abstract

The invention discloses an inorganic material pressure grouting machine for repairing holes and seams of concrete, which relates to a pressure grouting machine. The pressure grouting machine can generate powerful extrusion force, and can extrude slurry of an inorganic material into the holes and the seams of the concrete to guarantee the full repair of defects of the concrete. The pressure grouting machine comprises a support, a plunger cylinder and a jack, wherein the support comprises an upper round disk, a lower round disk and a plurality of bolts which are fixedly connected between the upper round disk and the lower round disk; the plunger cylinder comprises a plunger and a cylinder body, the upper end of the plunger is fixed under the upper round disk, the lower end of the plunger is inserted into the cylinder body, and the plunger and the cylinder body are glidingly connected by two sealing rubber rings; the plunger between the two sealing rubber rings is provided with a lubricating oil outlet; the cylinder body comprises a cylinder barrel, a cylinder bottom cover, and a rubber block; the cylinder bottom cover is arranged on the top end of the jack; the cylinder bottom cover in the cylinder barrel is provided with the rubber block; and the lower part of the cylinder barrel is provided with a slurry inlet pipe and a slurry outlet pipe. The pressure grouting machine is used for repairing the holes and the seams of the concrete by using inorganic slurry to overcome the defects caused by adopting organic material fillers.

Description

Technical field:

[0001] The invention relates to a pressurized grouting machine, in particular to an inorganic material pressurized grouting machine for repairing concrete holes and seams. Background technique:

[0002] In the field of construction, concrete components are very common. For various reasons, there are often defects such as "honeycomb, pockmarks, holes and cracks" in concrete components, which reduce their strength and affect the safety of the concrete components. For these defects In the construction industry, grouting is often used for repairing. At present, in the repairing and grouting of concrete, organic substances are mostly used as fillers, such as epoxy resin is used to inject the cracks to reinforce and repair concrete components. Wait. However, the fillers of organic substances are easy to age, have poor affinity with concrete, pollute the environment, and are affected by factors such as wet base surface, and often fail to obtain satisfactory result...
