在已建成建筑物的钢筋混凝土基础内埋入钢锚杆,并起压桩设备的支承作用,通过液压千斤顶,将预制钢筋混凝土桩压入地基土中形成桩基。这种地基加固方法,我们称为“锚杆静力压桩法”。1982年底至1983年初,我们用此法加固了芜湖市少年宫影剧院工程。本文扼要介绍施工实践和体会。一.工程概况与加固方案的选定该影剧院工程,建筑面积1386平方米,土建投资34.29万元。舞台部分檐高15.25
The steel anchor rods are embedded in the reinforced concrete foundations of the completed buildings, and they are supported by the pile driving equipment. Through the hydraulic jacks, the prefabricated reinforced concrete piles are pressed into the foundation soil to form pile foundations. This type of foundation reinforcement method is called “anchor static compression pile method”. From the end of 1982 to the beginning of 1983, we used this method to reinforce the Wuhu Children’s Palace Theatre project. This article briefly introduces construction practices and experiences. I. Selection of Project Overview and Reinforcement Plan The theater project has a building area of 1,386 square meters and a civil engineering investment of 342,900 yuan. The stage part rises 15.25
