Self-propelled tunnel grouting trolley

Abstract

The invention provides a self-propelled tunnel grouting trolley. The self-propelled tunnel grouting trolley comprises a rack, a platform, a main girder, a traveling mechanism and lead screw lifting jacks; the rack is an open-spandrel framework and is arranged on the traveling mechanism; the main girder is arranged on the rack; the platform comprises a working platform and lower platforms; the working platform is arranged on the main girder; the lower platforms are respectively arranged under the working platform at the two sides of the rack along the direction of a tunnel; one ends of the lower platforms are vertically fixed on the rack, the upper sides of the end parts of the other ends of the lower platforms are connected with the main girder through first supports, and the lower sides of the end parts of the other ends of the lower platform are connected with the rack through second supports; the two side end parts of the working platform and the two side end parts of the lower platforms are connected on the rack through inclined struts; the lead screw lifting jacks are symmetrically arranged at the two sides of the working platform and the lower platforms; and the self-propelled tunnel grouting trolley has the advantages of being reasonable in structure, low in cost, capable of solving the traffic problem in the tunnel, realizing the synchronization of grouting, transportation and other operations, meeting the requirements of the engineering construction of diversion tunnels with large-sized cross sections and being rapid and efficient in grouting operation and capable of ensuring the construction period.

Problems solved by technology

[0002] At present, in the domestic water conservancy and hydropower industry, the construction mode of scaffolding and grouting equipment is used in the grouting construction of large-scale water diversion tunnels. The construction method of this mode has the repeated installation and transportation of grouting equipment, and the construction distance of grouting equipment is short and continuous. Erection of bent frames, relocation of grouting equipment, laying of cables and pipes, dismantling of bent frames, etc., greatly increased the ineffective construction time, thus causing problems such as long construction period, large resource investment and high cost, and scaffold bents occupied a considerable amount in the tunnel During the grouting construction work, the transport vehicles cannot pass through, causing the space interference between the grouting work and the transport vehicles, and affecting the facilities and other materials required for tunnel construction, so that the tunnel drilling operation cannot be combined with the grouting construction work. In parallel, the grouting operation can only be carried out after the drilling operation is completed, which increases the construction time on site and seriously interferes with other process operations, resulting in work delays due to traffic in the tunnel, greatly reducing work efficiency and increasing engineering investment and labor intensity, resulting in low efficiency and long construction period. At the same time, the use of scaffolding has relatively large safety hazards. Therefore, it cannot meet the construction requirements of long-distance and large-size tunnels. It is necessary to seek advanced, practical, and low-cost construction facilities.
