HLC steel sheet pile foundation pit supporting system and construction method thereof
The invention is suitable for the technical field of building construction, and provides an HLC steel sheet pile foundation pit supporting system which comprises H-shaped steel and hot-rolled U-shaped steel sheet piles, the H-shaped steel and the hot-rolled U-shaped steel sheet piles are used in a matched mode according to models, and the hot-rolled U-shaped steel sheet piles are connected in an end-to-end meshed mode to form an enclosing purlin. The method has the advantages of being high in applicability, rapid in construction, low in cost and standard in product, has the closed waterstop performance of hot-rolled U-shaped steel sheet piles, also has the large rigidity and small deformation of H-shaped steel, and can be suitable for different types of foundation pit projects; the construction speed is higher than that of a concrete rigid support, foundation pit excavation work can be conducted without increasing the strength of concrete, due to the fact that the rigidity of the steel sheet piles is large, the steel sheet piles can be used under the condition that no inner support is arranged, and the construction period is short; after the foundation pit backfilling is completed, the HLC steel sheet piles can be pulled out for turnover use, and the manufacturing cost is low; the two kinds of steel sheet piles are both of common models, are produced in batches under a strict quality management system in the whole process and have universality.
本发明适用于建筑施工技术领域，提供了一种HLC钢板桩基坑支护体系，包括H型钢和热轧U型钢板桩，H型钢和热轧U型钢板桩根据型号配套使用，热轧U型钢板桩首尾咬合相接，形成一个围檩。本发明具有适用性高、施工快捷、成本低以及产品标准化的特点，既具备热轧U型钢板桩的闭合止水性，也具备H型钢的较大刚度，变形较小，可适用于不同类型的基坑工程；施工速度相较于混凝土刚性支撑更快，无需等混凝土强度增长即可进行基坑开挖工作，由于钢板桩刚度较大，可在不设内支撑的情况下使用，施工周期短；HLC钢板桩在基坑回填完成后，可拔出周转使用，造价较低；两种钢板桩均为常见型号，在全程、严格的质量管理体系下批量生产，具有通用性。
