Tie for tie separation of tunnel boring machine trolley and battery electric vehicle system and construction method thereof

Abstract

The invention discloses a tie for tie separation of a tunnel boring machine (TBM) trolley and a battery electric vehicle (BEV) system and a construction method thereof. The tie comprises a shield tunnel, wherein the shield tunnel is provided with upper ties and a lower tie which are detachably connected with each other; the upper ties comprise upper tunnel segments cooperating with the shield tunnel; the upper tunnel segments are provided with upper position lug plates, lower position lug plates and trolley traveling ties; the upper tunnel segments are provided with bending bolt lead screw heads; the lower tie comprises a bottom supporting tunnel segment; BEV traveling ties are arranged on the bottom supporting tunnel segment; and the upper ties and the lower tie are positioned in two planes. The tie for the tie separation of the TBM trolley and the BEV system has the beneficial effects of occupying little tunnel space, facilitating the dismounting and position shifting, improving thework efficiency, fully utilizing bending bolts in annular seams between the tunnel segments of side walls of the tunnel as the force supporting point of the independent novel tie for the suspension ofthe trolley, facilitating the stress transmission of the load of the trolley, achieving non-interference since the trolley and the BEV system can operate independently after the tie separation of thetrolley and the BEV system, and realizing the circulation use of the trolley traveling ties.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling, and in particular relates to a sleeper which is divided into a shield machine trolley and battery car system and a construction method thereof. Background technique [0002] Shield method tunnel construction technology has been widely used in the domestic subway market, municipal water delivery tunnels, power tunnels and other fields. Most of the walking sleepers are in the form of "triangular", and they are mostly combined with the walking sleepers of the battery car or share a long sleeper with the battery car. Most of the battery car walking sleepers are made of channel steel, angle steel and I-beam and other materials. In actual use, the traditional battery car and trolley walking sleeper more or less affect the use, the main performance is as follows: [0003] 1. It is easy to process with channel steel, and there is no need to install a small track pressure plate, but relatively ...

AI Technical Summary

Problems solved by technology

[0003] 1. It is easy to process with channel steel, and there is no need to install a small track pressure plate, but relatively speaking, the sleeper has low rigidity, which is easy to deform and cause the track to be buckled, causing the battery car to derail, and it is not easy to clean the muck near and on the sleeper;

[0004] 2. The processing of angle steel is fast and light, but because the track groove is shallow, it is easy to detach the groove and cause the battery car to derail, especially in the turning section of the tunnel

The height of the track is relatively low, and it is easy to be submerged by the muck hanging from the muck mouth, which affects the normal transportation of battery cars;

[0005] 3. The sleeper made of I-beam has high rigidity and high strength, and is widely used, but the processing technology is relatively cumbersome, and it is necessary to drill holes to install small track pressure plates. The actual installation is time-consuming and special track maintenance workers need to be arranged for maintenance, and the input cost is high. The probability of battery car derailment is lower than that of channel steel and angle steel sleepers
