After the construction of the underground diaphragm wall is completed, a shield machine is usually used for cutting part of the underground diaphragm wall in order to arrange an underground space. And the underground continuous wall usually adopts a reinforcement cage as a concrete pouring framework, so that part of the structure of the reinforcement cage can be cut by a shield machine. In the embodiment, as shown in fig. 1, the reinforcement cage includes a shield cutting segment 101, which is a main framework of a shielded area of the underground diaphragm wall 100, and a first support 1011 and a second support 1012 are oppositely disposed on the shield cutting segment 101. The left side of the first support 1011 is the exterior wall soil 102 and the right side of the second support 1012 is the interior wall 103. In order to facilitate the shield machine to cut the shield cutting section 101 in the later construction, optionally, the first support member 1011 and the second support member 1012 are both made of glass fiber reinforced plastics, so that the shield machine is light in weight, high in strength and convenient to hang and mount. And the glass fiber ribs have good corrosion resistance and long service life.
As shown in fig. 1, the present embodiment provides a reinforcement structure of a reinforcement cage, which includes at least one reinforcement assembly including a concrete support column 1, a new and old concrete connector, and a grout pipe 3.
The both ends of concrete support column 1 are connected respectively in first support piece 1011 and second support piece 1012 to support first support piece 1011 and second support piece 1012, prevent that two support pieces from taking place to warp, consequently, the difficult local displacement that takes place of steel reinforcement cage, thereby when hanging the steel reinforcement cage, can pinpoint it and fix. After the steel reinforcement cage is accurately positioned, the protective layer with the standard thickness can be obtained by integrally pouring concrete into the steel reinforcement cage, and the construction quality of the underground continuous wall 100 is improved. Preferably, the concrete support column 1 is the same number as the concrete poured in the reinforcement cage. The concrete with the same mark number is adopted, so that the texture of the concrete members of each part in the underground continuous wall 100 is uniform, and the reliability of the underground continuous wall 100 is improved.
In this embodiment, the concrete supporting column 1 is a prefabricated independent member, and before the reinforcement cage is suspended underground, the concrete supporting column 1 can be fixed between the two supporting members in advance. Optionally, in order to facilitate the installation of the concrete support column 1, the reinforcing assembly further includes a connector, the connector penetrates through the concrete support column 1, and two ends of the connector are respectively connected to the first support 1011 and the second support 1012. Specifically, the connecting member is an iron wire, and one end thereof may be bound to the first support member 1011 and the other end thereof may be bound to the second support member 1012. Binding operation, simple operation and firm fixation. Of course, the connecting member may also be fixed to the two supporting members by welding, screwing, or other methods, which are not described herein again.
After the reinforcement cage with the concrete support columns 1 is hung underground, the space where the reinforcement cage is located can be integrally poured to form the main body of the underground continuous wall 100. In order to ensure that the connection between the concrete support column 1 and the concrete poured in the reinforcement cage is reliable, the new and old concrete connecting pieces are arranged on the concrete support column 1. Optionally, the new and old concrete connecting piece is a brittle connecting pipe 2, and the brittle connecting pipe 2 is sleeved outside the concrete supporting column 1. The inner side of the brittle connection pipe 2 is attached to the concrete support column 1, and the outer side of the brittle connection pipe is coated by concrete poured in the reinforcement cage, so that comprehensive connection between the brittle connection pipe and the concrete support column is realized. When the cutter head of the shield machine is used for cutting the brittle material, the abrasion is small, and the cutting efficiency is high. In this embodiment, the brittle connection pipe 2 is a plastic pipe, and the concrete support pillar 1 can be directly poured into the plastic pipe by using the plastic pipe as a mold. And the plastic pipe is convenient to cut, and shield construction of the shield machine is facilitated.
After the concrete poured into the reinforcement cage is cured, the main structure of the underground diaphragm wall 100 is formed. In order to prevent water from continuously permeating into the underground continuous wall 100 along both side walls of the brittle joint pipe 2 and further eroding the structure of the underground continuous wall 100, the reinforcing assembly optionally further comprises a first annular water stop member 4 and a second annular water stop member 5, as shown in fig. 2 and 3. The first annular water stop 4 is attached to the inner wall of the brittle connection pipe 2 along the circumferential direction, and the second annular water stop 5 is sleeved outside the brittle connection pipe 2. In this embodiment, the first annular water stop 4 and the second annular water stop 5 are annular plates that block water flow radially inward and outward of the frangible connection 2.

In this embodiment, the grout pipe 3 is a thin-walled iron pipe, which is pre-embedded in the concrete support pillar 1. When the shield cuts, the influence of the thin-wall iron sheet on the cutter head of the shield machine is small, and the shield construction efficiency is improved.
In order to prevent water from continuously permeating into the underground continuous wall 100 along the two side walls of the grout pipe 3 and further corroding the concrete support column 1, the reinforcing component optionally further comprises a third annular water stop member 6 sleeved outside the grout pipe 3, as shown in fig. 1. In this embodiment, the third annular water stop 6 is also an annular plate, which can widen the radial dimension of the slurry filling pipe 3 outside the slurry filling pipe 3, thereby playing a role in retaining water. Further, the third annular water stop 6 can also be made of thin-wall iron sheet and welded outside the slurry supplementing pipe 3.
Optionally, there are two third annular water stop members 6, and the two third annular water stop members 6 are arranged in the concrete support column 1 at intervals. In this embodiment, two third ring-shaped water stop members 6 are respectively pre-arranged at two ends of the concrete support column 1, so that the erosion of the inner structure of the concrete support column 1 caused by water flow can be effectively avoided.
