Street lamp foundation square foundation pit excavation device
The invention relates to the field of building construction, in particular to a street lamp foundation square foundation pit excavation device which comprises a breaking hammer, a tunneling body is installed on the breaking hammer through a connecting part, the tunneling body is of a rectangular structure with an opening in the bottom face, and a pressure bearing part is arranged on the top face of the tunneling body. The pressure bearing part is used for buffering impact generated by a drill bit of the breaking hammer in the tunneling process; a working part is arranged at the position of a bottom opening of the tunneling main body and comprises angle iron and four non-return plates, the angle iron is arranged at the position of the bottom opening of the tunneling main body at intervals, and the four non-return plates are rotationally arranged at the positions close to the inner side edge of the bottom opening of the tunneling main body respectively. In the excavation process of the foundation pit, the non-return plate can apply forward pressure to the bottom of the foundation pit in the excavation process, disturbance to undisturbed soil is reduced, in the lifting process, the non-return plate can be kept horizontal under the limiting effect of the angle iron to form a soil retaining area, and then a clear foundation pit edge is reserved, so that the foundation pit is prevented from being damaged on the premise that the undisturbed soil is not disturbed. And the excavation quality of the square foundation pit is ensured.
本发明涉及建筑施工领域，具体为一种路灯基础方形基坑开挖装置，包括破碎锤，破碎锤上通过连接部安装有掘进主体，掘进主体呈底面开口的矩形体结构，掘进主体顶面上设置有承压部，承压部用于缓冲掘进过程中破碎锤的钎头产生的冲击；掘进主体的底口位置设置有工作部，工作部包括角铁和止逆板，角铁间隔设置在掘进主体底口处，止逆板设置有四个且分别转动设置在靠近掘进主体底口内侧边处。基坑开挖过程中止逆板能够在挖掘过程中，给与基坑底部正向压力，减少了对原状土的扰动，在抬升过程中，止逆板可以在角铁限位作用下保持水平，组成一个挡土区域，进而留下清晰的基坑边缘，从而在不扰动原状土的前提下，保证方形基坑的开挖质量。
