Embodiment Construction
[0039] Attached to the following Figure 1-6 This application will be described in further detail. The embodiment of the present application discloses a unitized construction method for an underground connection channel.
[0040] refer to figure 1 , 2, a unitized construction method of an underground connection channel, firstly, a starting space 1 is dug out by open-cut construction, the construction surface 2 of the underground connection channel is determined, and the construction surface 3 is detachably connected to the construction surface 2. 2 is divided into at least two layers, and the construction surface 2 of each layer is provided with a plurality of construction units 21 at intervals; and when the construction unit 21 is excavated and constructed, the construction units 21 at the corresponding oblique angles of the upper and lower layers can be simultaneously carried out. In the construction, finally, the excavation construction is carried out on the construction...

This application relates to the field of civil construction, and discloses a unitized construction method for underground connecting passages. S1. A starting space is dug out by open-cut construction, the construction surface of the underground connecting passage is determined, and the construction surface is detachably connected to the construction surface. The division mechanism divides the construction surface into several construction units; S2. When excavating the construction units, the construction units corresponding to the oblique angles connected by the upper and lower floors can be constructed at the same time. S3. Gradually construct and excavate the construction surface in a unitized manner until a complete installation path is excavated, then install the channel main body, and the channel main body is spliced by multiple channel units. The application has the following advantages and effects: the unitized construction method is adopted, and the small-section construction is combined into a large-section underground connecting passage, which reduces the need to increase the overall construction energy consumption due to the strong part of the mountain when excavating a large area. .
Description
technical field [0001] The present application relates to the technical field of civil construction, and in particular, to a unitized construction method of an underground connection channel. Background technique [0002] Underground passages are also known as underground sidewalks. In the traffic system with relatively congested and complicated traffic, there are often some non-surface traffic networks. These non-surface traffic networks generally refer to the underground sidewalks; the underground part of the underground sidewalks It is made of thicker concrete cement and thicker steel bars to ensure the bearing capacity of the top surface. [0003] At present, the patent with publication number CN103437772A discloses a pipe jacking construction method for underground passages and tunnel structures. Through repeated pouring and pipe jacking construction on site, the aperture of the tunnel during construction is not restricted by the hoisting equipment, and the aperture can...
