Description

Technical Field

[0001] The invention relates to the technical field of a grouting sleeve mechanism for an anchor cable, in particular to a grouting sleeve mechanism for an anchor cable. Background Art

[0002] Grouting sleeves for anchor cables are usually used in the fields of slope support, mining engineering, tunnel construction, etc. in geotechnical engineering. Their main function is to reinforce and anchor the anchor cables and the rock and soil layers through grouting. Grouting sleeves usually use thin-walled metal pipes or plastic corrugated pipes. Metal pipes have high strength and durability, while plastic corrugated pipes have good flexibility and grouting performance.

[0003] At present, anchor cable grouting is performed by inserting a casing into the middle of the anchor cable to form an annular space between the casing and the anchor cable as a grouting channel. During grouting, the slurry enters the anchor cable hole through the grouting casing.

[0004] However, in the prior art, except for the bottom of the grouting sleeve placed on the anchor sleeve, the other parts do not contact the anchor. During grouting, if the grouting pressure is too large or uneven, the sleeve may be subjected to uneven reaction force, thereby causing shaking, and then the grouting pipeline is offset, resulting in blockage or unevenness of the grouting channel, making it impossible for the slurry to fully fill the predetermined area, affecting the density of the grouting and the reinforcement effect. Summary of the invention

[0005] The object of the present invention is to provide a grouting sleeve mechanism for an anchor cable to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sleeve body, a guide tube is arranged around the bottom of the sleeve body, a first telescopic groove is opened at the front end of the inner wall of the guide tube, a first spring is arranged in the first telescopic groove, the outer side of the first spring is connected to the telescopic tube, a support plate is arranged at the outer end of the telescopic tube, a roller anchor cable sleeve is arranged between the two groups of support plates, and multiple groups of steel wire bundles are arranged around the top of the anchor cable sleeve; and a ring, the ring is clamped around the steel wire bundle, and multiple groups of clamping plates are arranged around the inner side of the ring.

[0007] Preferably, a slot is provided in the middle of the top of the anchor cable sleeve, and a plug-in base is provided at the bottom of the sleeve body, and the plug-in base is fixedly plugged into the slot.

[0008] Preferably, a second grouting port and a first grouting port are respectively provided at the upper and lower ends of the front end of the telescopic tube, and the grouting liquid can flow out from the first grouting port and the second grouting port, and the upper and lower ends of the telescopic tube are grouted simultaneously. The rear end of the telescopic tube is connected to the first spring in the first telescopic groove on the inner wall of the front end of the guide tube, and the telescopic tube can be telescoped in the first telescopic groove.

[0009] Preferably, the outer end of the telescopic tube is connected to a roller via a support plate, and the roller can be supported around the anchor hole and slide on the inner wall thereof, so that the sleeve body can be quickly inserted into the anchor hole.

[0010] Preferably, the guide tube has limiting grooves at the upper and lower ends of the first spring respectively, and limiting blocks are provided at the upper and lower ends of the inner side of the telescopic tube. The limiting blocks are clamped in the limiting grooves. The limiting blocks can limit the telescopic tube through the limiting grooves to prevent the telescopic tube from falling off from the front end of the guide tube.

[0011] Preferably, a plurality of groups of connecting rods are connected to the sleeve body, the number of groups of connecting rods is the same as the number of groups of steel wire bundles at the top of the anchor cable sleeve, and the front end of the connecting rod is connected to a ring, which is sleeved on the steel wire bundle to support the steel wire bundle and prevent the steel wire bundle from tilting.

[0012] Preferably, a second telescopic groove is formed around the inner side of the collar, a second spring is arranged in the second telescopic groove, the outer side of the second spring is connected to the holding plate, and the second spring can drive the holding plate to telescope in the second telescopic groove.

[0013] Preferably, the sleeve body can transmit the vibration generated by grouting to the steel wire bundle sleeved by the ring at the front end of the connecting rod through the connecting rod, so that the steel wire bundle is squeezed and collided with the second spring, and the shaking force is dispersed to the steel wire bundle.

[0014] Preferably, a roller is provided in the middle of the inner side of the holding plate, and the roller can be tightly attached to the outer sides of the wire bundle. The roller can provide assistance for the ring to slide on the wire bundle to prevent the wire bundle from blocking the descent of the ring driven by the sleeve body, resulting in the inability to quickly install the sleeve body.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a grouting sleeve mechanism for anchor cables. First, the anchor cable sleeve at the bottom of the anchor cable is inserted into the anchor cable hole. Then, the bottom of the sleeve body is aligned with the middle of the steel wire bundle connected around the top of the anchor cable sleeve. The sleeve ring connected to the connecting rods around the sleeve body is sleeved on the steel wire bundle. Then, the sleeve body is pushed to slowly descend. At this time, the telescopic tube squeezes the first spring connected to the rear end and shrinks to one end of the first telescopic groove, so that the telescopic tube can be placed in the anchor cable hole. At the same time, the roller connected to the support plate at the outer end of the telescopic tube is supported on the inner wall of the anchor cable hole, so that the sleeve body can be quickly descended in the anchor cable hole. At the same time, the inner clamping plate of the sleeve is passed through the sleeve body. The roller in the middle of the inner side is slidably connected with the steel wire bundle to prevent the steel wire bundle from hindering the descent of the casing body. When the plug-in base at the bottom of the casing body is plugged into the slot opened at the top of the anchor cable sleeve, the grouting liquid is injected into the casing body through the opening at the top of the casing body. The slurry flows along the casing body to the bottom of the casing body, and flows into the telescopic tube through the guide tubes around the bottom of the casing body, and then flows out from the first grouting port and the second grouting port at the upper and lower ends of the front end of the telescopic tube, and grouting is performed on the upper and lower ends of the telescopic tube at the same time; during the grouting process, if the casing body shakes, the casing body can transmit the shaking force to the ring through the connecting rod. At this time, the clamping plate on the inner side of the ring will squeeze and collide with the steel wire bundle, and further transmit the shaking force to the steel wire bundle through the telescopic action of the second spring, thereby buffering the shaking of the casing body. This mechanism can effectively prevent the grouting pipeline from being offset, avoid blockage or uneven grouting in the grouting channel, and ensure that the slurry can fully fill the predetermined area.
