Description

The diving slurry casting machine

One, technical field: the present invention relates to a kind of chemical grouting device, especially a kind of diving slurry casting machine.

Two, background technology: the underwater portion generation rhegma of water retaining structure, must cause and leak.Hole, a few place seam of a dam upstream face leaks, and through the dam body dismemberment, can cause the leaking hole seam of dam back side to spread all over the place, and what particularly minimum capacity of a reservoir was following leaks.The root of not diving beneath the water is difficult to be repaired, and makes diving slip casting be widely used.Be existing diving slip casting facility, pore-creating under water earlier before the slip casting (pick seam boring and bury Grouting Pipe underground), given grouting pressure will be with the submerged depth adjustment. from waterborne calm the anger adjust pressure can slip casting.The Grouting Pipe of burying underground under water will being caused of having is waterborne, slip casting on the water.Pore-creating is very difficult under water, and the difficult accurately control of grouting parameter roots such as grouting amount, grouting pressure is regulated and control in diving slip casting on the water, has hindered the progress of diving slurry injection technique.

Three, summary of the invention:, just be to provide a kind of novel diving slurry injection technique, i.e. the diving grouting device of the direct slip casting of not pore-creating in task of the present invention.This task is achieved in that the present invention's slurry casting machine of diving under water annotated rifle, sucked type slip casting box and gas storage mud jacking bag three parts and formed by two crossing, it is characterized in that annotating the rifle front end at biliquid installs sucked type slip casting box, the gas storage mud jacking bag that is equipped with is the capsule that holds slurries that 4 are made of latex, and be contained in 1 gas storage mud jacking bag of making of flexible material to collection, 4 defeated holes of starching that 4 feed pipe for mortar of containing milk capsules and ratio are annotated gunman's handle both sides link into an integrated entity again.

Upstream face at the leaking hole seam uses the diving slurry casting machine, and the leaking hole that utilizes sucker just can seek under water stitches, and leaks and cause negative pressure under sucker, sucker is adsorbed on the upstream face of Pu Shuikong seam.At this moment slip casting, slurries retrain through sucker, only can enter the hole seam that leaks under the inducing of leaking, and have controlled in the slurry stream dehydration, have realized the direct slip casting of not pore-creating under water.Slurries hole seam inner gel intercept leak after, the negative pressure under the sucker has not just existed, thus real-time test the effect of grouting for water plugging.

Chemical grout by the bi-component preparation, quantitatively is divided in 4 storage milk capsules, and collection is put into 1 gas storage mud jacking bag, is bearing same pressure, so that implement the energy storage two fluid grouting.The storage slurry and the gas storage mud jacking parts of the configuration of diving slurry casting machine adopt soft body structure entirely, and inflating given energy storage grouting pressure must be with the submerged depth adjustment.The slurries of enabling one by one during slip casting in the storage slurry strand capsule quantitatively supply slurry, make grouting pressure and grouting amount quantitatively to control, and make diving slip casting break away from regulation and control waterborne, have alleviated work under water.
