Abstract

本发明涉及一种建筑基础用的连续式静力压桩机，桩体上每隔一定距离设有一个桩箍，每个桩箍绕桩体一圈，其截面形状为一倒梯形，桩体左右两边分别设有上下两液压马达，链轨环绕上下两液压马达，链轨上与桩箍等距离设有数个棘突，棘突正好勾住桩箍，液压马达固定于底盘上，本连续压入式静力压桩机通过液压马达驱动链轨上的棘突，将桩体连续压入地下，其压桩效率比间歇性压桩机提高一倍。

Description

连续压入式静力压桩机
一、技术领域
本发明涉及一种静力压桩机，特别是一种建筑基础用的连续式静力压桩机。
二、背景技术：
目前，静力压桩机都是间歇性的分数次将桩压入地下，即压入一次后再升起油缸，抱桩后收缩油缸将桩压入，如此反复。
三、发明内容：
本发明克服以上缺点，提供了一种连续式静力压桩机。
本发明是通过如下技术方案实现的：
一种连续压入式静力压桩机，桩体上每隔一定距离设有一个桩箍，每个桩箍绕桩体一圈，其截面形状为一倒梯形，桩体左右两边分别设有上下两液压马达，链轨环绕上下两液压马达，链轨上与桩箍等距离设有数个棘突，棘突正好勾住桩箍，液压马达固定于底盘上。
本发明具有以下的特点：
本连续压入式静力压桩机通过液压马达驱动链轨上的棘突，将桩体连续压入地下，其压桩效率比间歇性压桩机提高一倍。
四、附图说明：
下面结合附图对本发明作进一步的说明：
附图为本发明的结构示意图。
图中：1、桩体，2、桩箍，3、液压马达，4、链轨，5、棘突，6、底盘。
五、具体实施方式：
附图为本发明的一种具体实施例，该实施例桩体1上每隔一定距离设有一个桩箍2，每个桩箍绕桩体一圈，其截面形状为一倒梯形，桩体左右两边分别设有上下两液压马达3，链轨4环绕上下两液压马达，链轨4上与桩箍等距离设有数个棘突5，棘突5正好勾住桩箍2，液压马达3固定于底盘6上。
本发明工作时，左边的两液压马达顺时针方向转动，右边的两液压马达逆时针方向转动，液压马达在转动过程中驱动靠桩最近的两条链轨向下运动，链轨上的棘突勾住桩体上的桩箍将桩体连续压入土体。

Claims (1)
