Embodiment Construction
[0030] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that all the drawings of the present invention are in simplified form and use inaccurate scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.
[0031] The connecting channel construction method provided by the invention, such as figure 1 shown, combined with figure 2 , including the following steps:
[0032] S1: The connecting channel 20 is constructed after the completion of the underground space 10 connected to it, and the connecting underground continuous wall 30 adopts the method of planting bars to install a ring-shaped protective shell 40 on the outside of the connecting channel 20 to fix the connecting channel 20;
[0033] S2: A post-...

The invention relates to a connecting passage construction method. The connecting passage construction method comprises the following steps that S1, a connecting passage is constructed after an underground space connected with the connecting passage is completed, and an annular protective shell is arranged on the outer side of the connecting passage in a steel bar embedding mode through an underground diaphragm wall connected with the connecting passage, so that the connecting passage is fixed; S2, a post-cast strip is reserved between the connecting passage and the underground diaphragm wall; S3, the portions, within the range of a connecting opening, of a lining wall and the underground diaphragm wall are chiseled away; S4, reinforcing columns are arranged on the floor where the connecting opening is located and the floor below correspondingly; and S5, a top beam is arranged on the upper portion of the connecting opening, and a prying opening is formed in the lower portion of the connecting opening. According to the connecting passage construction method, the connecting passage is constructed after the underground space is completed, and the connecting opening is constructed after the connecting passage is completed, so that uniform settlement of the underground space and an overground structure is facilitated, and the construction safety is improved; and the connecting passage construction progress and the outdoor road construction progress are accelerated, roads nearby are made unobstructed, and the influence on material transportation of other projects around is reduced.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a connecting passage. Background technique [0002] With the development of the economy and the acceleration of urbanization, in order to meet the growing needs of citizens for travel, rail transit transfer, commerce, parking and other functions, in the dense urban center where the land is increasingly tight, a large-scale project will be developed in combination with urban construction and renovation. Underground space has become a necessity. As the link connecting adjacent underground spaces, the connecting passage plays a pivotal role. The existing construction method of the connecting passage cannot meet the uniform settlement of the structure during the construction of the underground space and the above-ground structure, which affects the construction safety. Contents of the invention [0003] The invention provides a construction method fo...
