Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as figure 1 As shown, the shield receiving method in the subway construction of the present embodiment includes the following steps:
[0022] (S1) Construction of the receiving well for receiving the shield machine;
[0023] (S2) Before the shield machine reaches the receiving well, set a monitoring section along the designed tunneling path of the shield machine. The monitoring section is connected to the receiving well and the length is not less than 50m. The monitoring point of the attitude of the shield machine, and the reinforcement treatment of the soil at the receiving end of the receiving shaft;
[0024] (S3) After the shield machine is excavated to the monitoring section, adjust the attitude of the shield machine once for each preset length of excavation, so that the excavation direction of the shield machine is ...

Abstract
The invention discloses a shield receiving method in subway construction. The shield receiving method comprises the steps that a receiving well used for receiving a shield tunneling machine is constructed; before the shield tunneling machine reaches the receiving well, a monitoring section is arranged along the designed tunneling path of the shield tunneling machine, the monitoring section is connected with the receiving well, the length of the monitoring section is not smaller than 50 m, a plurality of monitoring points used for detecting the posture of the shield tunneling machine are arranged in the stratum of the monitoring section, and a soil body at the receiving end of the receiving well is reinforced; after the shield tunneling machine is tunneled to the monitoring section, the posture of the shield tunneling machine is adjusted once every time the shield tunneling machine is tunneled by a preset length, so that the tunneling direction of the shield tunneling machine is adjusted towards the designed tunneling path until the shield tunneling machine and the designed tunneling path coincide and coincide; and receiving the shield tunneling machine in the receiving well by adopting a bracket. The method has the advantages of being high in accuracy, good in safety, low in operation difficulty, easy to implement and apply and the like.
Description
technical field [0001] The invention relates to the technical field of shield tunnel construction, in particular to a shield tunnel receiving method in subway construction. Background technique [0002] In subway shield tunneling construction, it is an important task to receive the shield tunneling machine when the shield tunneling machine is completed and reaches the key point. How to ensure the accuracy, stability, safety and difficulty of operation of the shield tunneling receiving work, and how to avoid problems such as settlement and leakage are key considerations in the shield tunneling receiving construction. In the existing shield machine receiving methods, when the shield machine is approaching the receiving shaft, the conventional deviation correction method is used to adjust the posture of the shield machine, so that the shield machine can finally enter the receiving shaft accurately, and the receiving end of the receiving shaft is a The door openings that have b...
