Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of building engineering, especially relate to a reinforcing system of the inclined lattice column of one column and one pile of underground engineering. BACKGROUND
[0002] In underground engineering, one column and one pile composed of a bored pile and a lattice column are generally used as a vertical support component, and the lattice column is welded on the reinforcement cage of the bored pile as a stand and is lowered together. Due to the fact that the verticality adjustment of the lattice column is not forceful or not in place, the disturbance in the concrete pouring process, and the unbalanced earth pressure on both sides of the lattice column in the soft soil layer, the verticality of the lattice column deviates and tilts, the stability and vertical bearing capacity of the tilted lattice column cannot meet the construction requirements, and the safety of the foundation pit is affected. In order to ensure the safety of the foundation pit, the tilted lattice column needs to be reinforced. The conventional reinforcing measure is to set a shear brace between the floor and the support of the enclosure structure to connect adjacent lattice columns, so that the tilted lattice column and the adjacent lattice columns form a whole, thereby effectively controlling the lateral deformation of the tilted lattice column and preventing its expansion. The disadvantage of this measure is that the shear brace is cross-laid, occupies a large area, cannot avoid the positions of the wall, column and other building structures of the underground structure, and causes obstacles to the construction of the underground structure. In addition, when the verticality deviation of the lattice column is large, for example, when the verticality deviation of the lattice column is more than 500mm, part of the tilted lattice column is located below the trestle, which results in insufficient vertical load capacity of the tilted lattice column to the trestle, affecting the safety of the use of the trestle. After the second support is removed, the tilted lattice column needs to be re-set with reinforcing measures, which results in complex reinforcing procedures and affects the construction progress of the underground engineering.
