Technical Field
[0001] The utility model relates to the technical field of underground structure construction, in particular to a waterproof structure at a junction of underground structures. Background Art
[0002] Underground structures are divided into arch structures, circular and rectangular tubular structures, frame structures, thin shell structures, and special-shaped structures according to their structural forms. The loads borne by underground structures are divided into the following three categories according to their functional characteristics and possible situations that may occur during use: permanent (main) loads, variable (additional) loads, and accidental (special) loads. The characteristics are permanent, variable, and accidental loads, and the joints of underground structures generally require waterproofing.
[0003] The existing underground structure joints are generally constructed by using water-swelling waterstop glue and embedded rubber waterstop. In actual use, when unconventional structure joints appear, such as the joints between the open-cut end wall of a subway and the top of a concealed tunnel, the construction process will be more difficult, and the waterstop cannot be reserved. Even if it can be reserved, it cannot be effectively protected and the waterproof effect cannot be ensured. There is a risk of leakage and seepage. When leakage and seepage occur, it is inconvenient to handle and repair, which reduces the practicality of the existing waterproof structure at the joints of underground structures.

[0034] In this embodiment, the waterproof structure 300 is a structure for achieving a waterproof effect.
[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the waterproof structure 300 includes a waterproof component 301 installed on the top of the concrete grouting layer 1 for isolating water, and a grouting component 302 installed on the concrete grouting layer 1 for grouting the intersection of the underground structure.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the waterproof assembly 301 includes a waterproof layer 3011 fixed on the top of the concrete grouting layer 1, a buffer layer 3012 fixed on the top of the waterproof layer 3011, a waterproof board 3013 fixed on the top of the buffer layer 3012, and a waterproof layer 3014 fixed on the right side of the side wall 2.
[0038] It should be noted that the left side of the waterproof board 3013 is fixed to the right side of the waterproof layer 3014, and the left sides of the buffer layer 3012 and the waterproof layer 3011 are fixed to the right side of the side wall 2, ensuring that the waterproof board 3013, the buffer layer 3012 and the waterproof layer 3011 can achieve the expected waterproof effect.
[0039] In addition, the bottom of the support 201 passes through the waterproof board 3013, the buffer layer 3012 and the waterproof layer 3011 in sequence and extends to the bottom of the waterproof layer 3011 and is fixed to the top of the concrete grouting layer 1, ensuring that the support 201 can be effectively fixed to achieve the expected protective effect.

In actual use, when an unconventional structural junction occurs, the grouting pipe is easier to set up and construct than the water stop belt, and there is no risk of being unable to protect or being easily damaged, thereby effectively avoiding the occurrence of leakage and seepage due to ineffective protection. After the subsequent grouting construction, the construction joint position can be effectively guaranteed to be relatively dense, and even if seepage occurs, it is easy to repair, thereby improving the practicability of the waterproof structure at the junction of underground structures and solving the problem of low practicability of the existing waterproof structure at the junction of underground structures.
