变频车、砂浆车、渣车及管片车是盾构施工中常用的工矿编组列车。为了解决传统的工矿编组列车单气路制动控制系统在启停时存在延时、不能无级调节刹车力等问题，对传统的工矿编组列车气路制动控制系统进行双作用气路改造，对制动装置加装一套气压控制管路，使得机车在制动时气缸迅速排气，从而解决了延迟问题，同时也保证在制动过程中能对气缸进气压力调节，实现制动过程可控，大大提高了机车制动的可靠性，解除了工矿编组列车制动不同步带来的安全隐患。通过这个小改进，希望对盾构施工过程中存在类似问题的项目提供一些参考和借鉴。

Locomotives,grout cars,muck cars and segment cars are the common mining marshaling train which is used in shield tunneling.The traditional mining marshaling train control has a single pneumatic control,this will lead to brake time delay and cannot make the braking step-less adjustment.In order to solve this problem,we have changed the single pneumatic control by double-acting pneumatic by adding a pressure piping on braking device.This will make the cylin-der exhaust quickly,so that the delay problem can be solved.Meanwhile,the cylinders will get step-less air press to make the braking controllable.It will be greatly improve the reliability of the locomotive while braking,and can avoid the braking out of sync.
