Embodiment Construction

[0025] Use the 20T ground crane 9 to transport the construction segments and road slabs 17 from the ground to the tunnel through the working shaft 7, and multiple 14T electric locomotives 6 in the tunnel drive the segment flat car 5 to transport the segments and drag the shield The special takeover trolley 4 for construction transports the ring-forming segment 11 for the excavation and laying of the shield machine 1,

[0026] When the shield is excavated, the ring segment 11 protruding from the inner side of the ring to protrude the support bump 25 is installed, and the road slab 17 that divides the upper and lower layers is laid on the support bump 25 synchronously; at the negative ring segment of the working well 7, A wellhead steel platform 28 with an opening 21 is set, which is used as a vertical passage entrance for transporting workpieces from the ground to the lower layer of the tunnel from the wellhead, forming separate transportation passages and construction sites for...

Abstract

A shield driving and synchronous road construction method for double layer highway tunnel belongs to tunnel construction technology field. It is characterized in that: mounting annular pipe piece with bracket, and laying a road plate for diving upper and lower layer on the bracket; setting a well mouth steel platform with an opening at the annular pipe piece place of the work well for conveying the vertical channel entrance of the workpiece to the tunnel lower part from the ground at the well mount to form a transport channel and a construction place with unique upper and lower layers, and form a synchronous road construction method with shield driving in previous and the road construction in the later, and four phases construction step is brought forward based on work procedure property.After actualizing the invention, the tunnel construction progress is accelerated and the construction period is shortened.

Description

Technical field: [0001] The invention belongs to the technical field of tunnel construction, specifically a technology for simultaneous construction of shield excavation of a double-layer highway tunnel and road structure in the tunnel. Background technique: [0002] With the rapid development of urban underground transportation projects in my country in the past ten years, large-diameter shield construction has been widely used in tunnel construction. According to domestic and foreign practices, the construction of the internal structure usually takes 4-6 months after the construction of the shield tunnel is completed, which is more obvious in the construction of long tunnels. In order to shorten the construction period, the method of synchronous construction is being studied at home and abroad, but the method of synchronous construction for double-layer highway tunnels has not been found yet. [0003] Similar construction methods include: [0004] Synchronous road constr...
