Abstract
The utility model relates to an injection grouting device, in particular to an adjustable high-pressure injection grouting device with the aim to solve the problems that an injecting grouting pipe is jammed and grout liquid is wasted due to the larger volume of the prior injection grouting device, and the injection grouting rate is small because of smaller injection grout pressure. The injection grouting device comprises a liquid storage cylinder body; a rubber plug, a bearing pad and a top pad are arranged in the liquid storage cylinder body. A spring is blocked and connected between the bearing pad and the top pad. A top cap is arranged at the top part of the liquid storage cylinder body. In addition, an ejector rod and a suction rod are also arranged. The diameter of the liquid storage cylinder is 15 mm to 20 mm, and the cubage is 15ml to 20 ml. The peripheral circle of the top part of the liquid storage cylinder body is provided with a boss. The peripheral circle of the top cap is fixed with the boss by bolts. The utility model has the advantages of smaller diameter of the liquid storage cylinder body and larger injection grouting pressure. The utility model is used for the grouting injection for cranks which can not be seen by naked eyes. The injection grouting rate can reach 95 percent, and the largest cubage of the liquid storage cylinder body is 20 ml. The grouting liquid can be used following the preparation. The grouting material is saved and the pipe body can not be jammed. The liquid storage cylinder body is connected with the top cap by bolts. The manufacture is simple and cracking can not easily happen. Each part of the crank can be effectively filled by using the injection grouting pipe. The injection grouting maintaining quality of the crank is guaranteed.
Description
Technical field
The utility model relates to a kind of slurry casting machine, is specially a kind of adjustable high-pressure slip-casting device that concrete structure member crevices is carried out the filling reparation.
Background technology
Distress in concrete is modal engineering disease, and its appearance can influence the intensity of concrete component, but most of crack all can be repaired.Pressure grout method is a kind of method of the most common mending concrete crack, and its construction technology is to adopt higher pressure, makes slurry inject the crack fast and solidifies, to reach the purpose that mends a split.In the prior art, usually adopt filling gun or syringe to repair thinner crackle, such as being to disclose a kind of slurry casting machine in 94201572 the patent documentation in the patent No., there is following problem in actual use in the slurry casting machine of this structure, 1, this slurry casting machine volume is bigger, be 60ml, thinner when the crack, slurries are annotated when not entering, the easy retrogradation of slurries, stop up Grouting Pipe easily, not only cause Grouting Pipe not reuse, and cause the waste of slurries; 2, because this slurry casting machine diameter is bigger, be 20～30mm, cross section is bigger, different requirements according to slip casting pressure, when changing the spring of different elastic force, can only produce the grouting pressure of 0.2MPa, 0.4MPa, 0.6MPa, when the crack slip casting that is used for that some are invisible to the naked eye, because grouting pressure is less, cause that the slip casting rate is less, repair coverage is less; 3, liquid storage cylindrical shell and top cap are screwed connection, complex manufacturing technology not only, and under big grouting pressure, easily burst apart.
Summary of the invention
The utility model is big and cause Grouting Pipe to stop up and the waste of slurries in order to solve existing slurry casting machine volume, and grouting pressure is less and make and problems such as the slip casting rate is less provide a kind of adjustable high-pressure slip-casting device simultaneously.
The utility model is to adopt following technical scheme to realize: adjustable high-pressure slip-casting device, comprise that the lower end is provided with the liquid storage cylindrical shell that slip casting is chewed, the plug that is slidingly matched with it from bottom to top is housed in liquid storage cylindrical shell successively, rim and top pad, be connected with spring between rim and the top pad, liquid storage cylindrical shell top is provided with the top cap that is mated, the upper end cooperates with top cap spiral when also comprising slip casting, the soup stick that screw thread when the push rod of jacking top, lower end pad and suction slurry in lower end and the rim is worked in coordination, inventive point of the present utility model is that the liquid storage barrel diameter is 15～20mm, and volume is 15～20ml.The utility model can be changed the spring of different elastic force according to the different requirements of slip casting pressure, can produce the grouting pressure of 0.8MPa, 1.2MPa, 1.8MPa grade, but in this scope internal pressure regulated at will.Diameter and the volume of the utility model by reducing the liquid storage cylindrical shell makes grouting pressure increase greatly, and slip casting diffusion radius reaches 0.8～1.5m, and the slip casting rate reaches more than 95%, and can save slurry with joining with usefulness.
Border, described liquid storage cylindrical shell top is provided with boss, and cap border, top is fixed by bolt and boss, not only processes easyly, and high pressure resistant, is difficult for bursting apart.
Compared with prior art, the utlity model has following advantage: 1, the liquid storage barrel diameter diminishes, and makes grouting pressure become big, can obtain high pressure in 0.8MPa, 1.2MPa, the 1.8MPa scope by changing spring, the crack slip casting that can be used for being invisible to the naked eye reaches more than 95% the slip casting rate; 2, liquid storage cylindrical shell maximum volume is 20ml, and charge only is about 13ml, can save slurry with joining with usefulness, does not stop up body; 3, the liquid storage cylindrical shell is connected by bolt with the top cap, not only process easy, and it is high pressure resistant, be difficult for bursting apart, this Grouting Pipe can make slurry can be filled in each position in the crack effectively in a word, thereby guarantee the slip casting repairing quality in crack, strengthen the bulk strength of concrete component, prolong the application life of concrete component.
