小直径盾构施工通风及降温措施探究

Research on Investigation on Ventilation and Cooling Measures for Small Diameter Shield Construction

在城市市政公用地下工程建设中,最适合采用小盾构进行施工,但在长距离、小断面、复杂地层中泥水盾构施工面临的最大问题是通风效果不理想,散热差。论文根据工程特点,提出相应的通风及降温措施,并验证了该方案的可行性。

In the construction of municipal public underground engineering,the small diameter shield is the most suitable for construction.However,in the long distance,small section and complex stratum,the biggest problem of slurry shield construction is that the ventilation effect is not ideal and the heat dissipation is poor.According to the characteristics of the project,the corresponding ventilation and cooling measures are proposed,and the feasibility of the scheme is verified.
