Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] like Figure 1-3 As shown, the steel sleeve is assembled in sections, including:

[0029] A plurality of cylinders 1 arranged side by side, and two adjacent cylinders 1 are connected together by a set of longitudinal bolts, each cylinder 1 includes an upper cylinder 101 and a lower cylinder 102, so The upper cylinder 101 and the lower cylinder 102 are connected into one body by two sets of transverse bolts;

[0030] A plurality of bottom frames 5 arra...

Abstract

The invention discloses a sectional assembling steel sleeve, and relates to the technical field of steel sleeve manufacturing. The technical problems that an existing starting and receiving steel sleeve cannot be subjected to sectional assembling, the construction convenience is poor, the installation time is long, the steel sleeve cannot be recycled, and therefore the construction cost is increased are solved. According to the technical scheme for solving the problems, the sectional assembling steel sleeve has the technical effects that the steel sleeve is formed by assembling and connecting a plurality of small steel structure modules into a whole, and therefore the steel sleeve can be assembled and disassembled many times, the construction convenience is good, and the steel sleeve can be recycled many times; although the manufacturing cost is high, the cost can be shared through repeated recycling, and a large amount of end reinforcing cost is saved; and the sectional assembling steel sleeve has more economic benefits especially on lines with more shield passing stations, and is suitable for being widely used and popularized.

Description

technical field [0001] The invention relates to the technical field of manufacturing steel sleeves, in particular to segmented and assembled steel sleeves. Background technique [0002] The current shield machine construction schemes mainly include the large pipe shed reinforcement scheme and the steel sleeve scheme. The steel sleeve technology is a new shield technology developed based on the principle of balance. Compared with the traditional shield starting technology, the safety performance is greatly improved. By installing a steel sleeve outside the shield machine, a closed space is formed between the shield body, steel sleeve, negative ring segment and reference ring, and the closed space is filled with fillers. Pressure holding treatment. Through the closed space of the steel sleeve, the shield machine can create a pressure environment when passing through the soil layer before starting, effectively preventing the occurrence of water gushing and sand gushing when th...
