Abstract
Description
Technical Field
[0001] The present application relates to the technical field of oil and gas pipeline engineering, and in particular to a TBM construction device and TBM construction equipment for a long-distance pipeline. Background Art
[0002] TBM (Tunnel Boring Machine) technology is comprehensively considered in combination with strategic development, technological development, market demand and other factors. Through the application prospects and potential of TBM technology in different industries and fields, it is necessary to establish a team with relevant professional knowledge and skills to evaluate the risks that may be faced in the implementation of TBM technology strategy, formulate corresponding response measures, and make prevention and response preparations in advance; promote the continuous development and innovative application of TBM technology from the aspects of technological innovation, product development, technology application, and establishment of supervision management system.
[0003] TBM technology is constantly innovating and developing. At present, TBM technology has realized automated control and intelligent construction. With the application of TBM technology in long-distance pipeline projects, combined with TBM technology for long-distance pipeline supervision personnel to better perform their duties in TBM positions, give full play to the role of tunnel supervision, enhance the professional level of supervision, it is more urgent to establish and improve the guidance documents, forms, systems, etc. for supervision in long-distance pipeline TBM technology.
[0004] The scale of domestic long-distance oil and gas pipeline construction continues to grow. In recent years, pipeline construction projects have adopted TBM tunnel crossing for the first time based on the needs of construction units, the requirements of crossing rights departments, and the constraints of geological conditions. The length is 6-10km, which is a dangerous project with great construction difficulty and high risk. Therefore, it is particularly important to ensure the construction quality and ensure the one-time success of the jacking tunnel.
[0005] (1) Domestic technology status
[0006] As the first time that the TBM single shield construction technology was adopted for a long-distance pipeline, the supervision experience was relatively limited and a complete set of guidance documents for supervision work was lacking. The risks involved in the construction process were not well understood and the quality control points were not well mastered. The main difficulties in carrying out TBM supervision work at present were the handling of adverse geology during TBM construction, equipment operation risk control, long-distance tunnel construction and transportation safety risks, and downhill excavation control.
[0007] (2) Current status of foreign technology
[0008] The development status of TBM shield technology abroad is very rapid. As an advanced underground tunnel excavation technology, shield has been widely used in many countries.
[0009] In Europe, TBM shield technology has become the main method for subway and railway tunnel construction. For example, cities such as London, Paris, and Berlin have used shield machines for subway construction. Shield technology has rich experience in application in Europe and has a high technical level. In Asia, TBM shield technology has also been widely used. Countries such as China, Japan, and South Korea have made significant progress in subway construction. New York, the United States, Sydney, Australia, and other places have also used TBM shield machines for subway tunnel construction. The development of shield technology in these regions is relatively new, but it has gradually been recognized and adopted.
[0010] In general, the development of shield technology abroad is at a relatively mature and widely used stage. With the acceleration of urbanization, the demand for the construction of subways, railways, and long-distance pipelines is increasing, and TBM shield technology has broad development space and market prospects. In the future, TBM technology will replace the traditional blasting excavation process and improve construction efficiency and safety, but the technical system for TBM technology to be used in long-distance pipeline projects is relatively lacking.
[0011] TBMs are mainly suitable for long-distance hard rock geological tunnel construction, but the probability of long-distance tunnel geology being solely hard rock geology is almost zero. Often during TBM excavation, unforeseen soft strata that are not suitable for TBM excavation are often encountered, such as faults, soft soil, mud-rock strata, etc. When encountering such strata, the soft surrounding rock exposed at the TBM shield tail position cannot be supported in time, which will lead to frequent collapses and great safety risks. At the same time, the collapsed bodies scattered in the tunnel require a lot of manual cleaning, resulting in very slow TBM excavation or even no excavation.
[0012] Open-type TBM is a type of tunnel boring machine, which is an automated tunneling equipment that integrates a complete set of tunnel construction processes such as excavation, support (such as anchors, arches, shotcrete, Mcnally system support, etc.), and slag removal. At the tail of the TBM shield, the equipment manufacturer configures the corresponding support equipment, which are arch installers, anchor drills, shotcrete sprayers, etc.
[0013] As shown in the "Schematic Diagram of the Sectional Arrangement of TBM Support Equipment", the densely arranged steel bars in the 120° range of the arch (also known as Mcnally system support, which is to insert the steel bars into the top shield in advance. As the TBM shield moves forward, the steel bars are naturally exposed at the shield tail to cooperate with the subsequent support of the steel arch frame to support the surrounding rock of the arch) implement synchronous support for the surrounding rock in the 120° range of the arch exposed at the shield tail, which can ensure that the 120° range of the arch will not collapse during the excavation process; the support equipment configured by the TBM also includes arch frame support, anchor support, shotcrete support, etc. in order of priority. Excavation first, support later, this is the characteristic of open TBM excavation technology.
[0014] When encountering soft strata during open TBM excavation, the conventional method is generally to use advance reinforcement of the soft strata in front of the TBM, such as advance large pipe shed grouting reinforcement or small pipe shed grouting reinforcement, and even freezing method for reinforcement of water-rich soft strata, etc. The reinforcement is tested and then excavated. Because conventional reinforcement methods are time-consuming, inefficient, costly, and difficult to construct, they cannot give full play to the advantages of high excavation efficiency of TBM equipment. For this reason, an upper anti-collapse cover and a side anti-collapse cover are set behind the cutter head of the tunnel boring machine. The combined effect of the upper anti-collapse cover and the side anti-collapse cover can prevent tunnel collapse. Utility Model Content

[0033] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

The long-distance pipeline TBM construction device and TBM construction equipment provided in the embodiments of the present application are used to solve the problem that in the existing design process, the upper anti-collapse cover and the side anti-collapse cover are fixed by welding, which increases the labor cost and time cost for later maintenance and replacement, thereby invisibly increasing the production input.

For water-rich soft strata, even freezing method is adopted for reinforcement, etc. The reinforcement is tested to be safe before excavation.
