Description
Technical Field
The utility model relates to the technical field of highway maintenance equipment, in particular to a grouting chuck special for a highway structural layer.
Background
The semi-rigid base asphalt pavement is widely used for high-grade roads in China, and the semi-rigid base has good plate property, load diffusion capacity, certain tensile strength, fatigue resistance, water stability and lower manufacturing cost, so that the semi-rigid base asphalt pavement is widely applied to China and other regions in the world. However, with the increase of service cycle, under the combined action of the dry shrinkage stress, the temperature stress, the traffic load and the rainwater, cracks are generated on the surface layer and gradually penetrate through the whole asphalt surface layer and the whole structural layer, so that the road surface structural layer is subjected to cavitation and slurry pumping under the combined action of more heavy vehicles and the rainwater, and further pits and subsidence occur on the road surface, which gradually becomes a key factor for disturbing the long-term service performance of the road surface.
In order to avoid the damage of the roadbed caused by structural layer diseases such as cracks, pits, subsidence and the like, the damage of the roadbed needs to be treated in time, at present, a drilling grouting mode is mainly adopted to treat the structural layer diseases, the existing drilling grouting is connected with a grouting pump through a joint screw thread, the other end of the joint screw thread is connected with a grouting pipe, and cement grout enters the interior of a pavement structural layer through an outlet at the bottom end of the grouting pipe and is diffused, infiltrated, filled and compacted and consolidated to the periphery. However, in the actual grouting process, the grouting pipe is likely to shake and burst due to the high grouting pressure.
SUMMERY OF THE UTILITY MODEL
The utility model provides a special chuck for grouting a road structural layer, which aims to solve the problem that a grouting pipe in the prior art bursts out in the grouting process.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
the utility model provides a special dop of highway structural layer slip casting, by the elbow, the valve, slip casting pipe and slip casting hold-down mechanism are constituteed, the elbow, the valve links to each other with slip casting pipe upper end import, slip casting pipe upper portion sets up the screw thread, slip casting hold-down mechanism is by the lead screw bull stick, the ball pressure disk, sleeve and rubber hold-down sleeve are constituteed, lead screw bull stick and slip casting pipe upper portion threaded connection, the pipe hole that the ball pressure disk passes through the middle part cup joints on the slip casting pipe of lead screw bull stick below, the ball pressure disk includes two upper and lower annular preforming, the ball dish and a plurality of ball at middle part, the ball is arranged in the ball dish, the sleeve is installed on the slip casting pipe of ball pressure disk below, rubber hold-down sleeve installs between the export of sleeve and slip casting socle bottom, rubber hold-down sleeve comprises a plurality of preforming and a plurality of rubber sleeve, every rubber sleeve arranges in between two upper and lower preforming.
And a valve is arranged on the elbow.
When the device is used, cement slurry is fed into the grouting pipe by the grouting pump through the elbow, then enters the interior of a pavement structure layer through the outlet of the grouting pipe, is diffused, infiltrated, filled, compacted and consolidated all around, if the grouting pipe shakes and erupts, the screw rod can be rotated, the screw rod drives the ball pressure plate to move downwards along the thread on the upper part of the grouting pipe, so that the sleeve is pushed to press downwards, the sleeve applies pressure to the pressing sheets of the rubber pressing sleeve, the rubber sleeve between the pressing sheets is forced to be fastened on the surface of the grouting hole, the friction force is increased, and the running stability of the grouting pipe is ensured.
The grouting clamp can be applied to drilling and grouting equipment for repairing a pavement structure layer, ensures the stability of a grouting pipe in the operation process, prevents the pavement from being damaged by shaking, bursting and collision, improves the working efficiency of repairing the pavement structure layer, saves manpower and material resources, and has the advantages of ingenious design, convenience in use, safety and reliability.

FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the ball pressure plate of the present invention;
fig. 3 is a schematic top view of the ball pressure plate of the present invention.
In the figure, 1 elbow, 2 grouting pipe, 3 thread, 4 screw rotating rod, 5 ball pressure plate, 6 sleeve, 7 outlet, 8 pressing sheet, 9 rubber sleeve, 51 annular pressing sheet, 52 ball plate, 53 ball and 54 pipe hole.
Detailed Description
As shown in fig. 1, 2 and 3, a special chuck for grouting of a road structure layer comprises an elbow 1, a grouting pipe 2 and a grouting pressing mechanism, wherein the elbow 1 is connected with an inlet at the upper end of the grouting pipe 2, the upper part of the grouting pipe 2 is provided with a thread 3, the elbow is provided with a stop valve, the grouting pressing mechanism comprises a screw rotating rod 4, a ball pressure plate 5, a sleeve 6 and a rubber pressing sleeve, the screw rotating rod 4 is connected with the thread 3 at the upper part of the grouting pipe, the ball pressure plate 5 is sleeved on the grouting pipe 2 below the screw rotating rod 4 through a pipe hole 54 at the middle part, the ball pressure plate 5 comprises an upper annular pressing sheet 51, a lower annular pressing sheet 51, a ball plate 52 at the middle part and a plurality of balls 53, the balls are arranged in the ball plate, the sleeve 6 is arranged on the grouting pipe below the ball pressure plate 5, the rubber pressing sleeve is arranged between the sleeve 6 and an outlet 7 at the bottom of the grouting pipe, the rubber pressing sleeve comprises a plurality of pressing sheets 8 and a plurality of rubber sleeves 9, each rubber sleeve 9 is placed between the upper and lower pressing plates 8.
When the device is used, cement slurry is fed into the grouting pipe by the grouting pump through the elbow, then enters the interior of a pavement structure layer through the outlet of the grouting pipe, is diffused, infiltrated, filled, compacted and consolidated to the periphery, if the grouting pipe shakes and erupts, the screw rod can be rotated, the screw rod drives the ball pressure plate to move downwards along the thread on the upper part of the grouting pipe, so that the sleeve is pushed to press downwards, the sleeve applies pressure to the pressing sheets of the rubber pressing sleeve, the rubber sleeve between the pressing sheets is forced to be expanded on the surface of the grouting hole, the friction force is increased, and the running stability of the grouting pipe is ensured.
