Embodiment Construction

[0030] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Establish communication channel interface 3 between the two underground spaces that have been built. In this example, if figure 1 Shown, two underground spaces are specifically basement and underground passage (basement roof 19, basement bottom 5, underground passage bottom 20 and underground passage top 7 such as figure 2 Shown), the construction communication passage interface 3 between the two, the construction method of described underground communication passage interface 3 comprises the steps:

[0032] Step 1. Consult the drawings, measure and set out the lines: consult the drawings of the completed underground passages and basements, the service life, and the form of support structures, investigate the surrounding pipelines and groundwater levels, and measure and release the e...

Abstract

The invention discloses a method for constructing an interface of an underground communication channel. The method comprises: consulting drawings, measuring and setting out lines; hardening the surface layer; setting a diversion pipe to drain and divert the soil at the interface of the communication channel; The communication channel interface of the basement adopts open-cut construction, and multi-layer I-beams A are installed between the basement exterior wall and the basement support structure, and the I-beams A are connected by connecting bars; the communication channel interface on the outside of the basement support structure adopts Underground construction. The beneficial effects of the present invention are: the construction method of the present invention fully utilizes the existing structures such as the basement outer wall and the basement support structure as force-bearing bodies to support the support structure of the communication channel interface, which is comparable to the prior art. Compared with it, it saves time and effort, greatly reduces the project cost and improves the construction progress.

Description

technical field [0001] The invention relates to the technical field of underground space support, in particular to a construction method for an underground space connection interface. Background technique [0002] The rise of urban underground space construction makes the underground structure present a diversified development. Under the action of the underground enclosure structure, the new underground spaces are independent and closed, blocking the connection between the underground spaces. In order to promote mutual circulation between underground spaces, communication channels and interfaces are usually set up between two underground spaces, and at the same time, the existing support structure between the two interfaces must pass through. The setting of the contact interface is inseparable from the protective structure, and the construction of the underground interface usually adopts the underground excavation method. [0003] After the underground structure is complet...
