Description

Inject the dam grouting device continuously

Technical field

The utility model relates to a kind of improvement of injecting type dam grouting equipment, specifically a kind of can be continual, the continuous injection dam grouting device of continuous injection.

Background technology

Reservoir dam build up come into operation after, through long-term operation, dam body tends to occur seepage, should in time repair.If long-term seepage can influence the normal utilization of reservoir, when serious, have the danger of dam break.For the seepage of dam, adopt the grouting treatment technology to reduce the dam body osmotic pressure usually.Because employed cement grout is superfine when grouting, particle mean size is not more than 10 μ m, so can adopt injection device to inject grouting.Present employed injection device, comprise injection tube, injection ram, slurry outlet nozzle, slurry intake, go out slurry check valve, advance slurry check valve, inlet pipe, Grouting Pipe, cement paste fluid cylinder, negative pressure pipe, air pump constitute, injection ram is located in the injection tube, and can under the effect of air pump, in injection tube, slidably reciprocate, slurry outlet nozzle is fixed on an end of injection tube, when injection ram when the far-end of slurry outlet nozzle moves, cement grout is inhaled in the injection tube, when injection ram when the near-end of slurry outlet nozzle moves, cement grout is extruded from slurry outlet nozzle, thereby injects grouting.The deficiency of this injection grouting equipment is: because injection ram sucks cement grout outward when moving, in just inject cement grout when moving, so can not inject continuously; Because cement is a kind of rapid hardening slurry, this discontinuous injection, it is inconsistent to cause cement grout to condense, and crack and bubble occur, influences construction quality.

Summary of the invention

The purpose of this utility model is to provide a kind of injection that can be continual, continuous, and can improve the continuous injection dam grouting device of grouting quality.

For reaching above purpose, the technical scheme that the utility model adopted is: this injects the dam grouting device continuously, constitute by injection tube, injection ram, slurry outlet nozzle, slurry intake, inlet pipe, Grouting Pipe and cement paste fluid cylinder, injection ram is located in the injection tube, inlet pipe inserts in the cement paste fluid cylinder, it is characterized in that: described slurry intake is established two, be located at the two ends of the same sidewall of injection tube respectively, and in slurry intake, being provided with into slurry check valve, two slurry intakes are connected with inlet pipe by the arm that advances to starch that is connected respectively; Described slurry outlet nozzle is established two, is located at the two ends of another sidewall of injection tube respectively, and is provided with out slurry check valve in slurry outlet nozzle, and two slurry outlet nozzles are connected with Grouting Pipe by the slip casting arm that is connected respectively; Be provided with the push-and-pull piston handle on injection ram, the push-and-pull piston handle stretches out from the guide cylinder of injection tube end, connects the pull bar of hydraulic press in the outer end of push-and-pull piston handle.

The utility model is also implemented by following measure: the outside of the push-and-pull piston handle on the described injection ram is provided with collapsible mantle, the front end of collapsible mantle is fixed on by interior retainer ring on the boss of injection ram, and the rear end of collapsible mantle is fixed on the guide cylinder by corresponding external fixation ring.

Describedly include steel ball and spring into and out of slurry check valve and constitute, belong to known technology, so seldom state.

The beneficial effects of the utility model are: compare with employed injection device in the present dam injection grouting, owing to be continuous, continual injection grouting, so can increase work efficiency, cement grout rate of set unanimity, crack and bubble can be avoided occurring in the cement grout, construction quality can be improved.
