[0033] This double-sleeve anchor bolt includes an anchor head, an anchor tube, a grouting sleeve, and a drainage sleeve. The anchor head is conical, wider at the top and narrower at the bottom, to facilitate insertion of the double-sleeve anchor bolt into the surrounding rock. The upper end of the anchor tube is fixedly connected to the anchor head. From the inside out, the anchor tube has a drainage chamber and a grouting chamber. The drainage chamber is used for drainage, and the grouting chamber is used for grouting. The grouting chamber is located in the lower middle part of the drainage chamber and surrounds it. The drainage chamber and the grouting chamber are not interconnected to avoid interference between grouting and drainage. The bottom of both the drainage chamber and the grouting chamber are open to facilitate subsequent drainage and grouting operations. The upper sidewall of the drainage chamber has multiple evenly distributed drainage holes communicating with it for drainage. Water in the surrounding rock enters the drainage chamber through these drainage holes and is finally discharged through the bottom opening. The outer sidewall of the grouting chamber has multiple evenly distributed grouting holes communicating with it for grouting. Grout in the grouting chamber is discharged into the surrounding rock through these grouting holes to improve the stability of the surrounding rock.

[0034] The connecting sleeve 1 is detachably connected to the lower end of the anchor pipe, preferably connected to the thread of the anchor pipe via the connecting thread 104, for connecting the bottom opening of the grouting cavity and sealing the bottom opening of the drainage cavity; during grouting, simply install the sealing component 2 3, that is, insert the slider 2 302 of the sealing component 2 3 into the slot 2 107 of the connecting sleeve 1. When the slider 2 302 is inserted into the bottom of the slot 2 107, the sealing component 2 3 is rotated by grasping the rotating rod 302, so that the slider 2 302 on the sealing component 2 3 rotates in the rotating groove 2 108, thereby restricting the axial movement of the sealing component 2 3 in the connecting sleeve 1. Then, the connecting sleeve 1 is connected to the grouting pipe to send the grout into the grouting cavity for grouting operation.

[0035] During drainage, simply install the sealing component 2 onto the connecting sleeve 1. Insert the slider 203 of the sealing component 2 into the slot 105 of the connecting sleeve 1. Once the slider 203 is inserted to the bottom of the slot 105, rotate the sealing component using the rotating cylinder 202. This causes the slider 203 on the sealing component 2 to rotate in the rotating groove 106, thus restricting the axial movement of the sealing component 2 within the connecting sleeve 1, allowing water to drain from the surrounding rock. The connecting sleeve 1 can then be connected to the tunnel drainage system. For each corresponding operation, simply install the corresponding sealing component. The structure is simple and easy to operate. The double-sleeve anchor bolt of this invention uses the upper section for drainage and the middle and lower sections for grouting, integrating drainage and grouting into one unit. This multi-purpose anchor reduces costs. During construction, only one anchor bolt needs to be driven in to complete subsequent grouting and drainage work. The integrated grouting and drainage structure eliminates the need for additional installations, simplifying construction and saving time and effort.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
