Soft soil deep foundation pit supporting structure for building construction and supporting construction method thereof
The invention discloses a soft soil deep foundation pit supporting structure for building construction and a supporting construction method thereof.The soft soil deep foundation pit supporting structure comprises a deep foundation pit, a side supporting structure, a bottom plate foundation structure and an inner supporting structure are arranged on the deep foundation pit, and the side supporting structure comprises an oblique shotcreting anchorage device, a waterproof curtain, a glass fiber rib drilling pile, a top beam and a waist beam; the end of the inclined jet grouting anchorage device is connected with the top beam, a supporting frame is arranged on the lower portion of the waist beam, a barb engineering pile is arranged at the bottom of the deep foundation pit in advance, a high-pressure jet grouting pit bottom reinforcing block is arranged on the top of the barb engineering pile, a bottom plate is arranged on the high-pressure jet grouting pit bottom reinforcing block, and a profile steel latticed column is embedded in the high-pressure jet grouting pit bottom reinforcing block. Main body inner top braces are arranged on the profile steel latticed columns, upper concrete inner braces are arranged between the top beams, steel pipe inner braces are arranged between the waist beams, waterproof side walls are arranged on the inner sides of the glass fiber rib drilled piles, and inverted braces are arranged on the waterproof side walls and the bottom plate. The method has the characteristics that the supporting strength and rigidity are better, the stability is greatly improved, and the deformation of the deep foundation pit is controlled.
本发明公开了一种建筑施工用软土深基坑支护结构及其支护施工方法，包括深基坑，深基坑上设置有侧支护结构、底板基础结构和内支撑结构，侧支护结构包括斜向喷锚具、止水帷幕、玻璃纤维筋钻孔桩、冠梁和腰梁，斜向喷锚具的端部与冠梁连接，腰梁下部设置有支撑架，深基坑的底部预设有倒刺工程桩，倒刺工程桩的顶部设置有高压旋喷坑底加固块，高压旋喷坑底加固块上设置有底板，高压旋喷坑底加固块上预埋有型钢格构柱，型钢格构柱上设置有主体内顶撑，冠梁之间设有上混凝土内支撑，腰梁之间设置有钢管内支撑，玻璃纤维筋钻孔桩内侧设置有防水侧墙，防水侧墙与底板设置有倒支撑。本发明具有支护强度和刚度较佳、稳定性大大提高及控制深基坑变形的特点。
