Description
Technical Field
The invention relates to the technical field of pipe curtain structures, in particular to a construction method for providing shear-resistant bearing capacity for a gapped discrete steel structure pipe row.
Background
With the rapid development of economy and the increasing population density of China, the ground developable resources are less and less, and the land utilization rate tends to be saturated. Therefore, the development of cities to underground spaces is a necessary trend for the development of the international metropolis. However, when underground structures are built in urban core areas and old urban areas, the problems of insufficient underground space, incapability of touching adjacent facilities and the like exist.
The existing underground excavation method in the field is gradually the preferred method for building underground structures in complex environments by virtue of the advantage that the underground excavation method has less interference to the ground environment. The pipe curtain method is used as an underground excavation method, and has the advantages of low noise during construction, small ground surface settlement, low construction space requirement, no need of road reconstruction and pipeline adjustment, suitability for underground construction of various soil bodies and the like.
However, in the existing pipe curtain structure, steel pipes are arranged in the longitudinal direction and connected with each other in the transverse direction through lock catches, and concrete is poured inside the steel pipes. Because the restraint effect of the transverse lock catch is weaker, a pipe shed supporting system is formed mainly by the longitudinal strength of a pipe curtain structure and the temporary steel arch frame in the earth excavation process. On the basis of the above, new Tube curtain structures, such as ntr (new Tube Roof) Tube curtain structure, sts (Steel Tube slab) Tube curtain structure, FCSR (Flange-Channel Steel Roof) Tube curtain structure, pcr (stressed Concrete Roof) Tube curtain structure, and bundle Tube curtain structure, have been developed in recent decades. However, considering the factors of overall rigidity, improvement of structural bearing capacity, isolation of underground water and the like, concrete needs to be filled in the steel pipe joints. But not only can the construction period be prolonged and the construction cost be increased, but also the construction difficulty and risk are increased; meanwhile, most pipe curtain structures are stressed longitudinally, so that the shearing-resistant bearing capacity of the transverse pipe joints and the lock catches among the pipe joints is small.
Therefore, how to ensure the shear-resistant bearing capacity of the steel-structured tube bank without filling concrete in the tube bank is a new technical problem to be solved urgently by technical personnel in the technical field.
