由于山东兖矿熄焦车轨道基础所在场地地质较为松软,4年前曾进行注浆施工加固,但经熄焦车长期的生产行走,出现了不均匀的基础沉降,对熄焦车的生产行走造成不利影响。在此次焦炉改造期间,对熄焦车轨道基础采用夯扩桩基加固。结合实际,阐述夯扩桩技术在熄焦车轨道基础加固施工中的应用。 As Shandong Yankuang quenching coke car track where the site is relatively soft geology, grouting reinforcement construction 4 years ago, but after long-term production of quenching car walking, there has been uneven foundation settlement, the production of quenching car walking Adversely affected During the coke oven transformation, the foundation of the quenched coke track was consolidated with rammed pile foundation. Combined with the actual situation, expounds the application of rammed-expanded pile technology in quenching the car track foundation reinforcement construction.
