Embodiment Construction

[0040] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] like Figure 1-4 As shown, a construction method for a three-hole road tunnel passing through an existing railway, comprising the following steps:

[0042] S1. Collect the geological data of the three-hole highway tunnel to be crossed by the existing railway area and the geographical coordinate information of the existing railway, and install a number of settlement monitoring sensors and displacement monitoring sensors on the existing railway;

[0043] S2. Utilize modeling software to establish a geological model according to the geological data collected in step S1, and import the geographical coordinate information, the line information and monitoring information of the three-hole highway tunnel into the geological model;

[0044] S3. Determine the geological type and carry out the construction of the main structure ...

Abstract

The invention relates to the technical field of tunnel engineering construction, in particular to a construction method for underneath passing of a three-hole highway tunnel through an existing railway. Through the above scheme, the geological data of the three highway tunnels crossing the existing railway area and the geographic coordinate information of the existing railway are collected, the sensors are arranged on the existing railway, the collected information is imported into the modeling software to establish the geological model, and then the information collected by the sensors is transmitted to the model in real time. And the next circulating footage is adjusted in real time according to the settlement amount, monitored by the sensor, of each circulating footage, so that the technical defect that in the prior art, the construction progress of the tunnel under construction cannot be adjusted in real time according to information such as settlement displacement of an existing railway during tunnel excavation is overcome.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering construction, in particular to a construction method for a three-hole highway tunnel passing under an existing railway. Background technique [0002] The existing method to reduce the construction settlement and disturbance of the existing operating track is: chemical grouting reinforcement stratum method, that is, to carry out grouting reinforcement in advance on the existing railway subgrade stratum and the stratum within a certain range below to improve the soil quality. parameters, so as to reduce the construction settlement and disturbance caused by tunnels and other buildings passing under or adjacent to the construction process. However, the grouting reinforcement method has many disadvantages: First, the grouting reinforcement construction itself will cause disturbance and settlement to the existing subgrade, especially in the loess area, where the collapsibility of the loess is...
