简介：摘要随着我国经济的发展，挤压式金属铸造对铸造设备的要求不断提升。因此，对挤压式金属铸造设备关键技术的研究具有重要的意义。本文首先对挤压铸造进行了概述，探讨了当前挤压设备的发展现状及挤压式金属铸造设备关键技术，旨在提高金属铸造的水平。

简介：摘要：着经济和城市建设的发展，城市基础设施日趋完善，市政道路下布置有煤气、热力、电力、给排水管道等各种地下管线,当需要新敷设地下管线时，传统的明挖施工因需要破坏道路，中断交通，改迁地下管线而无法实施。此时，顶管施工就比较合适。顶管施工不影响地面交通，不需要迁改地下管线，在交通繁忙、居民稠密、商业密布的城市中心地区，以及旧城改造和城市扩展工程中，顶管施工已成为城市基础设施建设中一种不可缺少的施工方法，应用越来越多。
