Problems solved by technology

[0005] However, the three patents already authorized by the inventor are only applicable to the follow-up supporting trolley of the shield machine with a cutterhead diameter D<6.28m and the sleeper system sleeper sub-sleeper of the flat-bed transport battery car; they are not applicable to those with D≥6.28m Subsequent supporting trolley for shield machine and flatbed transportation battery car sleeper system sleeper sub-sleeper
[0006] However, it has been nearly 200 years since the tunnel construction technology came out. With its continuous development, shield tunneling projects with super large diameters (that is, the diameter of the shield machine cutter head D≥6.28m) are not uncommon at home and abroad. Subsequent supporting flatbed transportation battery car bears a larger load, and its vertical load will be transmitted to the shield tunnel pipe ring segment ring body through the battery car sleeper. Due to the stress concentration, it is easy to damage the local concrete of the segment segment, which will cause sleeper deformation, Slipping, vibration, derailment of the steel wheel of the battery car, and the danger of overturning
[0007] Therefore, when the diameter of the cutter head of the shield machine is D≥6.28m, the existing battery car sleeper is difficult to meet the stability and safety of its work, especially when the battery car system is overloaded, the problem is even more serious

Embodiment Construction

[0036] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0037] As shown in the figure, a shock-absorbing, compression-resistant, anti-slip sleeper for subsequent transportation of a shield machine for a battery car relates to a shield tunnel pipe ring for installing a sleeper. The shield tunnel pipe ring is composed of several shield tunnel segments 7 and shield Tunnel ring segment annular seam waterproof tape 10 is assembled, and a shield tunnel ring annular gap 8 is formed between adjacent shield tunnel segments 7; the sleeper includes an arc-shaped steel plate belt 1, and the arc Shaped steel plate strip 1 fits the inner surface of the shield tunnel pipe ring, and it is arranged symmetrically with the longitudinal centerline of the lower part of the shield tunnel pipe ring in the arc length direction; There are more than 3 vertical load-bearing ribs 2 distributed evenly at intervals, and the top surfaces of th...

Abstract

A damping and anti-compression and sliding slip sleeper for a subsequent trolley transporting battery car of a shielding tunnel machine is provided. The damping and anti-compression and sliding slip sleeper is characterized in that an arc-shaped steel plate strip is applied to the internal surface of a shielded tunnel pipe ring; vertical bearing rib plates are arranged on the arc-shaped steel plate strip; the top surfaces of the vertical bearing rib plates are on the same elevation; and each vertical bearing rib plate is provided with a horizontal supporting member for installation and supportof a steel rail. The damping and anti-compression and sliding slip sleeper for the subsequent trolley transporting battery car of the shielding tunnel machine is advantageous in that the battery cartransmits load to the internal surface of the shielding tunnel pipe ring via the horizontal supporting members, the vertical bearing rib plates and the arc-shaped steel plate strip orderly; concentrated load vertically transmitted can be converted into surface load evenly distributed; stress to the local of the lower part of the shielding tunnel pipe ring is even, so lower part local concrete fracture can be effectively avoided and breakage, deformation and slippage of the local of the lower part of the shielding tunnel pipe ring can be prevented; work stability and safety can be enhanced; anda technical demand for super-large diameter shielding tunnel engineering construction can be met.

Description

technical field [0001] The invention relates to a battery car sleeper for subsequent transportation of a shield machine, which belongs to the technical field of underground space expansion, in particular to a shock-absorbing, pressure-resistant, anti-slip sleeper for a shield machine for subsequent transportation of a battery car with a cutter head diameter D≥6.28m and its construction method. Background technique [0002] In the shield construction, the follow-up trolley of the shield machine is required to follow the shield machine to move forward in the tunnel sleeper, and the soil cut by the cutter head of the shield machine and the segments used for assembling the tunnel are transported by the flat plate The battery car is transported on sleepers. [0003] In the past construction, the laying of sleepers imitated the sleepers of railway rails. The sleepers of large-gauge trolleys and small-gauge battery car sleepers were jointly laid. Cannot be recycled. [0004] For...
