Embodiment

[0065] Embodiment: The present invention provides a construction organization method of complete sets of mechanical equipment for tunnels,

[0066] (1) Construction organization method of tunnel body excavation and initial support

[0067] The construction quality of tunnel body excavation and primary support, especially the physical quality of primary support structure is an important guarantee to ensure the safety during tunnel construction. In the process of construction organization, the measures of "two close follow" of the initial support steel frame closely following the tunnel face and the initial support inverted arch are timely closed to form a ring and closely follow the lower steps, and at the same time strictly implement the excavation and support cycle footage of the upper steps 1~ 2 intervals between steel frames (2 intervals when the surrounding rock is stable, 1 interval when the surrounding rock is weak and poor in stability, and blocks falling off), and 2 inte...

Abstract

The invention discloses a complete set of tunnel mechanical equipment, which specifically refers to an excavation trolley (or an excavation gantry), a drainage and steel bar binding trolley, a liningtrolley, a spray maintenance trolley, a ditch cable trough trolley, an inverted arch self-propelled hydraulic trestle and a wet spray manipulator, referred to as five trolleys, one trestle and one wetspray machine. A construction organization method matched with the complete set of mechanical equipment comprises the following construction organization steps: S1, hole excavation; S2, initial support; S3, inverted arch lining; S4, arched wall lining; S5, ditch cable troughs and the complete set of mechanical equipment. The construction organization method is reasonable, effectively improves tunnel management effect, improves construction operation environment, ensures construction safety and quality, improves construction progress and is worthy of promotion.

Description

technical field [0001] The invention relates to a tunnel construction organization method, in particular to a tunnel construction organization method for complete mechanical equipment, belonging to the field of railway tunnel construction. Background technique [0002] The mechanized construction of railway tunnels in our country only started in the 1980s, starting with the construction of the Dayaoshan Tunnel on the Hengguang-Guangzhou double track, and then promoted and improved in the construction of Daqin, Nankun, Jingjiu, Xikang and other railways, forming a variety of mechanized Complete set of construction technology and equipment matching mode. With the improvement of domestic tunnel construction technology, mechanized construction has become the development trend of tunnel construction and is urgently needed. It is an effective way to improve construction efficiency and effectively ensure construction safety and project quality. [0003] In the past, the tunnel con...
