Description

Utility tunnel erector

Technical Field

The utility model relates to the technical field of comprehensive pipe gallery assembly, in particular to a comprehensive pipe gallery assembly machine.

Background

With the vigorous support of the urban comprehensive pipe gallery in policy in China, the comprehensive pipe gallery currently put into construction and used has two construction methods of cast-in-place and prefabrication. The cast-in-place is a traditional structural form which is widely applied at present, and the construction process is mature. The prefabricated comprehensive pipe gallery is a new construction form in recent years, has the advantages of short construction period, good structure quality, material consumption conservation, small influence on environment and life and the like, meets the requirements of building industrialization and greening, and is applied to a plurality of large-scale projects although the construction is started later in China. However, due to the influence of multiple factors, the prefabricated comprehensive pipe gallery lacks of standardized design standards and corresponding laws and regulations and management systems are not sound, so that the prefabricated comprehensive pipe gallery faces a plurality of problems in popularization and application.

At present, the application of the underground comprehensive prefabricated pipe gallery assembling technology in engineering has obtained certain achievements and experiences, but most of the existing research and practice aims at the assembling of the integral single-cabin prefabricated pipe gallery, the research locality of the multi-cabin large-tonnage prefabricated pipe gallery is obvious, and the referential result is limited.

In the prior art, as a 'prefabricated comprehensive pipe gallery installation positioning system' with the publication number of CN206267152U, a movable trolley is proposed to carry out pushing and splicing, namely, trolley tracks are embedded in a cushion layer in advance, the prefabricated sections are carried by the specially designed movable trolley, and the prefabricated sections are pushed to a design position and then are subjected to prestress tensioning and fixing. This kind of mode is little to the foundation ditch influence, need not carry out interim the operation of propping that trades, and the piping lane festival section is counterpointed efficiently, nevertheless increases the bed course construction degree of difficulty, and construction control is difficult, and is with high costs. The construction process for splicing the prefabricated sections of the urban comprehensive pipe gallery by using the crawler crane is described in detail by the 'splicing method' with the publication number of CN109024677A, and comprises the arrangement of a hoisting point and a hoisting frame. But great to the foundation ditch influence, need carry out local ground reinforcement, and the part needs to carry out interim the construction of trading propping, and wire rope is longer to be difficult to reach piping lane festival section alignment precision, and the installation effectiveness is low. Meanwhile, the stand of the crane can only adapt to the assembly of the single-cabin pipe gallery with light self weight. And the utility model is "a utility tunnel multidimension degree directional installation car" of CN201720937731.8, through adopting vertical lift, vertically slide, transversely slide, with the help of piping lane body structure and concrete cushion, realize the directional installation work of vertical, horizontal, vertical multidimension degree of prefabricated utility tunnel. The problem that a large-tonnage pipe rack transport vehicle is high in height and large in pipe joint length is considered in the mode, and the method can only be suitable for assembling of the light-weight single-cabin pipe rack.

Therefore, it is necessary to design a piping lane erector that is high to piping lane position control accuracy, and the flexibility ratio is high and be applicable to arbitrary section, arbitrary weight prefabricated utility tunnel and assemble.
