公路桥涵构筑物的混凝土工程量大,且有一个特点:每隔5～6m就要设置一道沉降缝。沉降缝之多不仅对混凝土墙的接缝提出了较高的要求,也给混凝土的连续浇筑带来了难度,影响了模板和脚手架等的周转。为了在不增大施工成本并在现有条件下解决这一问题,我们在某高速公路工程实践中进?
Highway bridges and culverts of the large amount of concrete structures, and there is a characteristic: every 5 ~ 6m will set up a settlement. The settlement of the joint not only on the concrete wall of the seams put forward higher requirements, but also to the continuous pouring of concrete has brought difficulty, affecting the template and scaffolding turnover. In order not to increase the construction cost and solve the problem under the existing conditions, we are in a highway engineering practice?
