[0002] With the rapid development of urban rail transit, more and more new urban rail lines are being built. During the construction of shield sections on soft soil foundations, the connecting channel is constructed using the freezing method. After the construction of the connecting channel structure is completed, melting and grouting are required. In the period of tight construction period and heavy tasks, in order to speed up the overall construction progress and ensure the opening node, the connecting channel of the shield section is often handed over to the track laying unit after the construction is completed. The melting and grouting of the connecting channel is constructed at the same time as the track laying. During the melting and grouting operation, the melting and grouting operation surface is narrow, and only the cable trough covers on both sides can be used to store construction machinery and a small amount of materials. Cement, water glass and construction machinery need to be transported to the site by rail vehicles. The transportation cost is expensive and the transportation time is difficult to determine. The narrow space on site is mainly used to stack cement and grouting equipment, and water glass concentrate cannot be stored. In addition, there are safety hazards due to its proximity to the track.
