Problems solved by technology

In the actual construction process, the land acquisition and demolition and pipeline relocation in the early stage of some projects are difficult, resulting in limited construction site conditions. Due to the high production efficiency of the TBM method, it is necessary to discharge the TBM slag and transport materials according to the actual conditions such as construction conditions. Reasonable analysis and comparison, selection of the optimal plan to improve efficiency, can ensure that the entire TBM construction maintains high efficiency

Embodiment Construction

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] like Figure 1 to Figure 4 As shown, the embodiment of the present invention provides a TBM hoisting and translation method in a deep well confined space. The hoisting process mainly includes the following steps:

[0034] S1, deep well hoisting

[0035] S2. Size and weight selection of main components of TBM;

[0036] S3, hoisting personnel allocation;

[0037] S4, hoisting equipment preparation;

[0038] S5. Selection of lifting equipment. The lifting equipment adopts Zoomlion QUY350 crawler crane main crane and QY160-ton truck crane to cooperate with turning over;

[0039] S6. Preparation of the construction site;

[0040] S7. Calculation of foundation bearing capacity;

[0041] S8, load rate calculation;

[0042] S9. Crane select...

Abstract

The invention discloses a TBM hoisting and translation method for a deep well confined space. The TBM hoisting and translation method for the deep well confined space comprises the steps that S1, deepwell hoisting is carried out; S2, the size and weight of TBM main parts are selected; S3, hoisting personnel are allocated; S4, hoisting machines and tools are prepared; S5, hoisting equipment is selected; S6, a construction site is prepared; S7, the bearing capacity of a foundation is calculated; S8, the load rate is calculated; S9, the crane selection performance is calculated; and S10, hoisting testing is carried out. The construction method solves the problems of deep well hoisting, large weight translation and slag discharge in a confined space in the field of urban rail transit, complexconstruction is avoided, the costs are saved, the construction experience of similar projects is accumulated for enterprises, the technical reserve of the enterprises is enhanced, guidance and reference for urban rail transit construction under similar conditions can be provided, and good promotion, application value and social influence are achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for hoisting and moving a TBM in a deep well confined space. Background technique [0002] With the rapid development of our country's economy and population growth, ground transportation can no longer meet the needs of people's life and travel. As a safe, convenient and broad available space, the development and utilization of underground urban rail transit is an important trend in the development of the world today. . In the construction of hard rock tunnels, two methods, drill and blast and TBM, are basically used. The drill and blast method has the advantages of low cost and flexible construction, but its disadvantages are low efficiency, poor construction conditions, and great safety hazards. Compared with the drill-and-blast method, the TBM method is a fast, safe and efficient tunnel forming method that uses a full-face tunnel boring machine for one...
