Embodiment Construction
[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention. For the convenience of description, the "up" and "down" described below are consistent with the directions of up and down in the drawings, but this should not be a limitation of the technical solution of the present invention.
[0035] combine Figure 1 to Figure 14 Illustrate the open-cut construction method of setting up the underground connecting passage between the new and old buildings of the present invention, as figure 1 and figure 2 As shown, the above-ground part of the old building 10 in this embodiment is a reinforced concrete structure, and there is no basement structure. The original foundation form is a st...

The invention discloses an open excavation construction method for additionally forming an underground connection channel between a new building and an old building, and relates to the technical fieldof reconstruction of existing buildings. The open excavation construction method aims at solving the problems that when an existing open excavation method is adopted to additionally form an underground connection channel below the old building, construction is difficult, and energy consumption is increased. The open excavation construction method comprises the following steps that an original foundation of a basement quasi additional arranging area of the old building is reinforced, and a hole is formed in an outer wall of the old building, so that constructors pass conveniently to carry outmechanical construction and material transportation, after foundation pit enclosure is conducted on an underground connection channel quasi additional arranging area outside the old building and the basement quasi additional arranging area inside the old building, earth is excavated, a basement of the old building and the underground connection channel are poured, and holes are formed in the outerwalls and underground continuous walls, corresponding to the two ends of the underground connection channel, of the old building and the newly-built building, so that the basement of the old buildingand a basement of the newly built building are connected into a whole through the underground connection channel.
Description
technical field [0001] The invention relates to the technical field of existing building reconstruction, in particular to an open-cut construction method for adding an underground connecting passage between old and new buildings. Background technique [0002] With the development of urbanization and the gradual improvement of urban development, the demand for urban construction has gradually changed from new construction to addition and reconstruction. The addition of underground passages to the lower parts of existing old buildings is a typical project. The addition of underground passages under old buildings can not only meet the convenience and comfort requirements of users, but also reduce the traffic pressure of surrounding buildings. [0003] At present, the main construction methods for adding underground passages under existing old buildings can be divided into open-excavation method and underground excavation method. Among them, the open-excavation method is suitabl...
