DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Refer to Figure 1, A basement raft anti-seepage structure on campus, including anchor pile 1. An anti-floating anchor 2 is vertically arranged inside the anchor pile 1. A waterproof layer 3 is arranged at the top of the anchor pile 1. A concrete cushion 4 is arranged around the waterproof layer 3. A first waterproof rubber sleeve 5 is sleeved outside the anti-floating anchor 2 at the top of the waterproof layer 3. A second waterproof rubber sleeve 6 is overlapped and sleeved outside the first waterproof rubber sleeve 5. A waterproof coiled material 7 is arranged between the first waterproof rubber sleeve 5 and the second waterproof rubber sleeve 6. The periphery of the waterproof coiled material 7 extends to the upper surface of the concrete cushion 4. The inside of the first waterproof rubber sleeve 5 is filled with asphalt waterproof ointment 8. A sealing strip 9 is sleeved on the anti-floating anchor 2 at the position corresponding to the upper surface of the asphalt waterproof ointment 8. The bottom end of the sealing strip 9 is in close contact with the upper surface of the asphalt waterproof ointment 8. A structural floor slab 10 is arranged at the top of the concrete cushion 4.

[0018] In this embodiment, both the first waterproof rubber sleeve 5 and the second waterproof rubber sleeve 6 include a vertically arranged cylinder part and a horizontal part connected to the bottom end of the cylinder part. The asphalt waterproof ointment 8 is filled in the cylinder part of the first waterproof rubber sleeve 5. The side surface of the horizontal part of the first waterproof rubber sleeve 5 is closely attached to the side surface of the concrete cushion 4.
