Problems solved by technology

like figure 1 As shown, the traditional plane layout is generally in the form that the vertical shaft is located on one side of the line, and the axis of the horizontal passage is orthogonal to the direction of the line: this layout increases the working surface for the subw...

Embodiment Construction

[0025] Such as figure 2 A city subway π-shaped double vertical shaft and double horizontal channel plane layout system shown, including the tunnel center line 1, is characterized in that: it also includes a vertical shaft 2 and two horizontal channels 3; One side; both sides of the shaft 1 are respectively connected to the cross passage 3 through the arc-shaped transition section 4, and the middle part of the cross passage 3 intersects with the tunnel center line 1 at a certain angle. The plan layout system takes into account that the setting of the cross passage 3 must meet the functional requirements of shield tunneling and underground excavation parallel construction. One cross passage 3 is set on each side of the shaft 2, and the two cross passages 3 are obliquely intersected with the main line tunnel respectively. It is π-shaped, and after the completion of the construction of the horizontal passage 3, the construction of the main line tunnel can be carried out.

Abstract

The invention discloses an urban subway n-shaped double-shaft and double transverse passage plane arrangement system. The system comprises a tunnel middle line (1), and is characterized by also comprising a shaft (2) and two transverse passages (3), wherein the shaft (2) is excavated in one side of the tunnel middle line (1) in a concealed manner; the transverse passages (3) are communicated with the shaft (2) through cambered transition sections (3) respectively; the middle parts of the transverse passages (3) are crossed with the tunnel middle line (1) at a certain angle. The system has a safe and stable structure and can simultaneously meet the requirement on concealed excavation and shield construction without mutual affection. The shafts and the n-shaped double transverse passages realize concealed excavation in a narrow range and parallel construction of a shield; the construction progress and the construction efficiency are improved; the cost is saved; a reference is provided for design and construction of the shafts and the transverse passages of metros in future.

Description

technical field [0001] The invention relates to the field of subway construction, in particular to a plane layout system for urban subway π-shaped double vertical shafts and double transverse passages. Background technique [0002] Under the current situation, domestic subway construction is developing rapidly. However, since the subway construction site is located in an urban area, it is different from other railway and highway constructions. The construction site is small and must not affect traffic. It has always been a problem that subway construction needs to overcome. Such large-scale equipment is widely used in subway construction. It is even more difficult to solve such problems, especially when the stations at both ends of the shield tunneling section cannot meet the starting or receiving conditions of the shield machine, these problems are particularly prominent. [0003] Most of the subway constructions are located in urban areas, and the construction progress of...
