Shield segment transport and maintenance vehicle

Abstract

The invention discloses a shield segment transport and maintenance vehicle, which relates to the technical field of shield tunneling engineering construction. The shield segment transport and maintenance vehicle includes a vehicle frame (1), the front middle part and the rear middle part of the vehicle frame (1). Respectively protrude from an external trailer connecting device (11); the running mechanism (2) is installed under the vehicle frame (1); and the maintenance base (3) is arranged on the top of the vehicle frame (1). A segment maintenance water tank (31) for storing and maintaining the shield segment is provided on the surface. The shield segment transport and maintenance vehicle of the present invention effectively improves the maintenance quality of the shield segment, facilitates the transportation and transfer of the shield segment, and reduces the transportation cost.

Description

technical field [0001] The invention relates to the technical field of shield tunneling engineering construction, in particular to a shield segment transport and maintenance vehicle. Background technique [0002] The shield segment is the main assembly component of the shield construction, and the quality of the shield segment is directly related to the overall quality and safety of the tunnel. The shield segment belongs to the large-volume reinforced concrete. In addition to the control of the concrete mix ratio pouring process, its maintenance control also directly affects the durability and strength of the structure. At present, the maintenance of shield segments is basically covered with geotextiles and plastic films, and artificially sprinkled with water pipes. Its disadvantage is that manual sprinkling not only does not cover in place, but also has low efficiency and consumes a lot of labor. Especially in the high temperature weather in summer, the water evaporates t...

Problems solved by technology

The disadvantage is that manual sprinkling not only does not cover in place, but also has low efficiency and consumes a lot of labor.

Especially in high temperature weather in summer, the water evaporates too fast, it is difficult to guarantee the quality of concrete curing

[0003] In addition, during the segment maintenance work in the shield tunnel segment production and storage workshop and the shield tunnel construction site, the shield tunnel segments are stored on the ground at random, the shield segment placement is relatively mobile, the transportation cost is high, and the shield segment It is a circular arc-shaped reinforced concrete structure, which is large in size and takes up a lot of space, which is not conducive to the storage of multiple segments

Moreover, there are many types of shield segments, which are not conducive to selection during storage and use selection; at the same time, it is easy to cause structural damage such as knocking edges and corners on the segments during hoisting
