[0001] The present invention relates to underground construction technology, and particularly to a technology for micro-disturbance implantation of prefabricated structural components in underground engineering. Background Art

[0002] For the construction of underground structures such as traditional pile foundations, deep foundation pit support, and underground structures, processes such as bored cast-in-place piles, diaphragm walls, jacked precast piles, driven precast piles, and caissons are mostly used. These processes have certain limitations on the formation and have a greater impact on the surrounding environment. The precast components used in the vertical shield tunneling process of assembled precast components are all solid structures. Since they are connected by bolts, their structural integrity, structural strength, and waterproof effect are not ideal. Summary of the Invention

[0004] To solve the above technical problem, a prefabricated structural component for micro-disturbance implantation in underground engineering provided by the present invention includes a plurality of double-H structural members, and each double-H structural member includes two outer structural plates and two inner structural plates. The two outer structural plates are arranged at intervals front and back. The two inner structural plates are arranged between the two outer structural plates and at intervals left and right. The front edges of the two inner structural plates are fixedly connected to the front outer structural plate, and the rear edges of the two inner structural plates are fixedly connected to the rear outer structural plate. The left inner structural plate and the left parts of the two outer structural plates form an H-shaped structure, and the right inner structural plate and the right parts of the two outer structural plates form an H-shaped structure. A casting hole that penetrates up and down is enclosed by the two outer structural plates and the two inner structural plates. On each of the two outer structural plates, there are two through holes, one on the left and one on the right, and the four through holes are respectively located at the joint parts of the two outer structural plates and the two inner structural plates. Vertical tongue-and-groove interfaces are provided on the upper and lower sides of the double-H structural member, and horizontal tongue-and-groove interfaces are provided on the left and right sides of the double-H structural member.

In other embodiments, other materials such as steel can also be used for production.

[0014] During the construction of the first embodiment of the present invention, a plurality of double-H structural members can be horizontally and vertically assembled to form an underground structural wall.

[0015] As Figure 3As shown in the figure, when horizontally assembling two double-H structural members in the first embodiment of the present invention, the adjacent side horizontal tongue-and-groove interfaces of the two double-H structural members are aligned and then joined together. Then, bolts are screwed into each bolt hole 4 and fixed to the ground or the lower double-H structural member, so as to position the two horizontally assembled double-H structural members. After the two horizontally assembled double-H structural members are positioned, a pouring hole 5 is enclosed at the joint of the two double-H structural members.

[0016] As Figure 4 shown in the figure, when vertically assembling two double-H structural members in the first embodiment of the present invention, the lower vertical tongue-and-groove interface of the upper double-H structural member is aligned with the upper vertical tongue-and-groove interface of the lower double-H structural member and then joined together. Then, bolts 7 are screwed into each bolt hole 4 of the upper double-H structural member, and the bolts are inserted into each bolt hole 4 of the lower double-H structural member and fixed to the lower double-H structural member, so as to position the two vertically assembled double-H structural members.

[0017] After forming an underground structural wall by horizontally and vertically assembling multiple double-H structural members, concrete is poured into each pouring hole 3, each pouring hole 5 and each bolt hole, so that each double-H structural member is bonded together. After the concrete solidifies and forms, the construction of the underground structural wall is completed.

[0018] During the process of assembling the underground structural wall, fixed clamping members can be placed in the clamping grooves 6 of each double-H structural member to keep the assembled wall stable.

[0019] As Figure 5 shown in the figure, the first embodiment of the present invention further includes a corner structural member, and the corner structural member includes a first outer structural plate 301 of the corner member, a second outer structural plate 302 of the corner member, and an inner structural plate 303 of the corner member; The first outer structural plate 301 of the corner member and the second outer structural plate 302 of the corner member are arranged at intervals front and back.
