Problems solved by technology
[0003] The present invention needs to solve the technical problem that the original beam-type bracing cannot be constructed during the construction stage of the large underground space, and provides a brace-changing system with sufficient strength, rigidity, and stability to ensure that the underground structure can resist the application of water and soil in the unfinished stage.

Embodiment Construction
[0016] Such as image 3 As shown, the basement wallboard and enclosure replacement system of the present invention includes a lattice column 1, a foundation floor 2, a first concrete support 3, an enclosure 6, an underground second floor roof 7, a bentonite waterproof blanket 5 and extruded Polystyrene board insulation layer 4.
[0017] The base plate 2 and the first concrete support 3 are supported and connected by the lattice column 1, and the enclosure 6 is used on both sides to support the wall panels of the second underground floor, and bentonite is laid between the enclosure 6 and the wall panels of the second underground floor for waterproofing Blanket 5 and extruded polystyrene board insulation layer 4.
[0018] The construction method of the basement wall panel and enclosure replacement system, the specific steps are:
[0019] 1) When the strength of the foundation floor 2 meets the design requirements, the second concrete support 8 is removed, and the extruded poly...

The invention relates to a basement wall plate and containment support changing system and a construction method. The system comprises a latticed column, a foundation bottom plate, a first path concrete support and an underground two-layered top plate, wherein the foundation bottom plate is connected with the first path concrete support through the latticed column in a supporting manner; and an underground two-layered wall plate is supported by containment at the two sides; and a bentonite waterproof carpet and an extruding polyphenyl plate heat-preservation layer are paved between the containment and the underground two-layered wall plate. The basement wall plate and containment support changing system is a novel support changing system which combines a basement structure outer wall plate to form a framework type combined support to commonly resist lateral force of the structure. The basement wall plate and containment support changing system adopts a basement structure outer wall plate so that the working amount of the backfilling construction of a foundation pit is reduced and the removing construction period of a template of an outer wall plate structure is saved. The basement structure outer wall plate and the newly-established support are combined to be stressed so that the rigidity and the stability of support changing are enhanced.
Description
technical field [0001] The invention relates to a construction method using basement outdoor wall boards instead of a bracing system, which is suitable for bracing construction with a small distance between a foundation pit enclosure system and an underground space structure in core urban areas. Background technique [0002] During the construction of conventional underground structures, due to the lack of floor slabs and small space spans, only reinforced concrete beams or profiled steel beams can be constructed at the corresponding parts to meet the support requirements. In the construction of large underground space structures, the missing area of the structural floor is large, the floor height is high, and the space span is large. It is difficult to ensure the reasonable stress and construction safety of the replacement brace from the perspectives of strength, stiffness and stability. The distance between the space structure and the maintenance system of the foundation...
