Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grouting, especially to a pulse type inner wall pipeline anti-sticking fissure grouting device. BACKGROUND

[0002] In the pulse type grouting process, due to the intermittent flow of slurry, when the slurry flows in the pipeline, the solid particles in part of the slurry may deposit on the inner wall of the pipeline. Especially when the slurry viscosity is high, this deposition phenomenon is more obvious, and with the passage of time, the deposited particles will gradually increase, causing the inner wall of the pipeline to become rough, further increasing the resistance of the slurry flow. When the slurry is discharged through the hole of the grouting device, the width of the fissure is small or changes greatly, and the slurry may be hindered when entering the fissure. Part of the slurry may backflow at the entrance of the fissure and mix with the slurry at the outlet of the pipeline, forming a more complex sticking phenomenon. This sticking not only affects the injection effect of the slurry, but also may cause blockage at the outlet of the pipeline. When the outlet of the pipeline is blocked, not only the work efficiency is affected, but also the grouting effect is poor. SUMMARY

[0026] Reference Figures 1-4For the first embodiment of the utility model, provide a kind of pulse inner wall pipeline anti-sticking fissure grouting device, it includes shell 100, it includes respectively being arranged at two ends drill bit 101 and injection hole 102, several groups of discharge hole 103 being opened in the lateral wall of shell 100 and support table 104 being arranged at the side close to drill bit 101, the circumferential lateral wall of shell 100 is arranged in arc, the output end of drill bit 101 is conical, discharge hole 103 is identical with the inside of shell 100.

[0027] Specifically, staff can punch hole by shell 100 at the required position, then inject slurry into shell by injection hole 102, slurry is discharged along the discharge hole 103 of the circumferential lateral wall of shell 100, when slurry fills hole, shell 100 can be extracted.

[0028] Further include anti-blocking assembly 200, it is arranged in the inside of shell 100 and it includes the fixed connection of limit table 201 away from the side of support table 104 drill bit 101, the rotation connection of limit column 202 with limit table 201, the fixed connection of anti-blocking component 203 with limit column 202 and the transmission member 204 being arranged at the side of limit column 202 away from limit table 201, limit table 201 is limited to limit column 202 in vertical direction, limit column 202 one end and limit table 201 rotation cooperation.

[0029] Further, the circumferential lateral wall of limit column 202 is fixedly provided with anti-blocking component 203, anti-blocking component 203 is provided with several groups, and anti-blocking component 203 includes the rotation table 203a fixedly connected with limit column 202, the side away from limit column 202 of rotation table 203a is arranged in arc and is attached to the inner wall of shell 100.

[0030] Further, rotation table 203a corresponds to discharge hole 103, and the side close to discharge hole 103 of rotation table 203a is provided with telescopic hole 203a-1, and anti-blocking component 203 further includes telescopic part 203b matched with telescopic hole 203a-1, telescopic part 203b includes telescopic spring 203b-1 fixedly connected with the end of telescopic hole 203a-1 and pusher 203b-2 fixedly connected with the other end of telescopic spring 203b-1, pusher 203b-2 is matched with discharge hole 103 and pusher 203b-2 can pass through discharge hole 103.

[0031] Further, the inner wall close to discharge hole 103 of pusher 203b-2 is arranged in arc, and when pusher 203b-2 does not contact discharge hole 103, it abuts against the inner wall of shell 100 and extrudes telescopic spring 203b-1 to shrink, and the side opposite to the rotation direction of rotation table 203a and limit column 202 is provided with scraper 203c.

[0032] Further, the scraper 203c is fixedly connected with the rotating table 203a, the scraper 203c is arranged obliquely to the side of the discharge hole 103, the oblique bottom of the scraper 203c is horizontal with the lowest point of the discharge hole 103, and the transmission member 204 is spirally arranged.

[0033] Specifically, when the slurry is discharged into the shell 100 through the injection hole 102, the slurry will first pass through the transmission member 204, and the slurry will exert a certain force on the transmission member 204 in the process of contacting the transmission member 204. At this time, since the transmission member 204 is spirally arranged, a certain rotation will be generated in the circumferential direction, and the rotation of the transmission member 204 will drive the rotation of the limiting column 202, and the limiting column 202 will drive the rotation of the rotating table 203a. During the process of discharging the slurry along the transmission member 204 from the discharge hole 103, the hole diameter of the discharge hole 103 may be blocked. At this time, the pushing member 203b-2 on the rotating table 203a is always in a state of extruding the extension spring 203b-1 in the process of contacting the circumferential side wall of the shell 100. When the pushing member 203b-2 reaches the position of the discharge hole 103, the extension spring 203b-1 will release the elastic force to push the pushing member 203b-2 into the discharge hole 103 at this time. At this time, the slurry blocked in the discharge hole 103 will be cleaned. Since the limiting column 202 is still rotating, the side of the pushing member 203b-2 in contact with the discharge hole 103 is arranged to be inclined, so that when the pushing member 203b-2 contacts the side wall of the discharge hole 103 on the other end again, it will easily shrink through the contact of the inclined surface with the side wall of the discharge hole 103. If stirring is required to make the slurry more uniform, a motor can be arranged inside the limiting table 201 and connected with the limiting column 202, so that the motor drives the limiting column 202. In this way, the stirring effect can be increased, and the slurry can be filled more uniformly.

[0034] Operation process: After the pushing member 203b-2 passes through the discharge hole 103, the scraper 203c contacts the inner side wall of the shell 100 to scrape the slurry. Since the scraper 203c is inclined to the side of the discharge hole 103, the slurry scraped by the scraper 203c will be scraped into the discharge hole 103. The oblique bottom of the scraper 203c is horizontal with the lowest point of the discharge hole 103, which can increase the efficiency of the scraper and prevent the scraped slurry from not entering the discharge hole.
