Embodiment Construction

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.

[0030] refer to Figure 1-7 , a preferred embodiment of the present invention provides a shield escape method, characterized in that, comprising the following steps:

[0031] S10: Modify the excavation cutter set of the shield machine to increase the excavation diameter of the shield machine;

[0032] S20: Replace multiple sets of hinged cylinders between the middle shield and the tail of the shield with the connecting protective member 10 of rigid structure;

[0033] S30: Between the middle shield and the tail of the shield, add multiple sets of auxiliary oil cylinders respectively connected to the two.

[0034] In the shield tunneling method of the present invention, when the excavation cutter group of the shield tunneling machine is modified to increase the e...

Abstract

The invention discloses a shield escape method. The method is characterized by comprising the following steps of S10, modifying an excavation cutter set of a shield tunneling machine to expand the excavation diameter of the shield tunneling machine; S20, correspondingly replacing a plurality of groups of hinged oil cylinders between the shield middle and the shield tail with connecting protectioncomponents with rigid structures; and S30, adding a plurality of groups of auxiliary oil cylinders connected with the shield middle and the shield tail correspondingly between the shield middle and the shield tail. Compared with the prior art, the shield escape method is ingenious in thought, convenient and efficient, the problems that during existing shield construction, due to the fact that theshield tunneling machine generates large thrust under the special working condition, the operation efficiency is low, or even tunneling is difficult are effectively solved, the problems are solved with cooperation of the method in multiple aspects, normal tunneling can be recovered within multiple rings, and therefore, the working efficiency is improved, smooth and safe construction is guaranteed,a method reference is provided for the condition that it is difficult for the shield tunneling machine to tunnel due to large thrust in the future, and high universality, good social benefits and good popularization and application prospects are achieved.

Description

technical field [0001] The invention relates to the field of shield tunneling construction, in particular to a shield tunneling method. Background technique [0002] As my country's urban development becomes more and more saturated, the demand for underground space development continues to increase, and the use of shield construction is becoming more and more common. Due to uneven construction control levels, geological factors or long-term downtime, it is inevitable that the thrust of the shield machine will increase and it will be difficult to excavate. Under such extreme shield working conditions, the existing processing methods are mainly Increase the thrust of the shield to get out of trouble. Relying on increasing the propulsion force of the shield machine to get out of trouble, on the one hand, the speed of getting out of trouble is very slow, which leads to low construction efficiency and prolonged construction period; In addition, it is easy to cause damage to the...
