一、前言随着筑港事业的飞速发展,混凝土工程量与日俱增。木模板施工已由钢模极取而代之。虽然钢模板施工可以节约大量木材,增加模板周转次数并降低模板成本,但在实际施工过程中,发现有些钢模板之间,以及钢模板与底模之间等部位的衔接因加工、组装等原因,不易做到密封,新灌混凝土会从其缝隙中溢出,混 I. INTRODUCTION With the rapid development of the port construction industry, the number of concrete works is increasing day by day.

Although the steel formwork construction can save a lot of wood, increase the number of template turnovers and reduce the cost of the formwork, during the actual construction process, it was found that some steel formworks, and between the steel formworks and the bottom formwork, were connected due to processing, assembly, etc. , It is not easy to be sealed and the new concrete will overflow from its crevice and mix.
