Communication iron tower pipe pile foundation
The invention relates to a communication iron tower pipe pile foundation in the field of fixed building foundations, through an embedded cylinder embedded in a foundation body and an anti-shearing cylinder embedded in the embedded cylinder and extending into a tower body, when the tower body swings, horizontal shearing force borne by the tower body is transmitted into the embedded cylinder by utilizing the anti-shearing cylinder, and therefore the tower body swings; the large axial contact area between the tower body and the shear-resistant cylinder and the large axial contact area between the embedded cylinder and the shear-resistant cylinder are utilized, horizontal shear force borne by welding bolts is reduced, and the problem that stress is excessively concentrated on the embedded bolts is solved. Meanwhile, by means of the inclined anchor rods arranged on the lower portion of the foundation body, the road holding force of the foundation body under the action of swing inertia is enhanced, the stability of the foundation body is improved, and the better offset effect on horizontal shearing force is achieved; in addition, vibration of welding bolts installed on the upper portion of the pre-embedded cylinder is reduced through a damping ring arranged between the shear-resistant cylinder and the pre-embedded cylinder, and the stability of connection between the tower body and the foundation body is improved.
本发明涉及固定建筑基础领域的一种通信铁塔管桩基础，通过预埋在基础本体内的预埋筒以及嵌套在预埋筒内并延伸至塔体内的抗剪筒，在塔体发生摆动时，利用抗剪筒将塔体受到的水平剪切力传递到预埋筒内，利用塔体和预埋筒两者与抗剪筒之间具有较大的轴向接触面积，减小焊接螺栓受到的水平剪切力，克服应力过于集中在预埋螺栓的问题；同时，通过设置在基础本体下部的斜锚杆，增强基础本体受到摆动惯性作用时的抓地力，提高基础本体的稳定性，对水平剪切力具有更好的抵消效果；另外，通过设置在抗剪筒和预埋筒之间的减震圈，减少安装在预埋筒上部焊接螺栓的振动，提高塔体和基础本体连接的稳定性。
