技术领域technical field
本实用新型涉及一种建筑工程结构，尤其是涉及一种加筋钢板桩基坑。The utility model relates to a construction engineering structure, in particular to a reinforced steel sheet pile foundation pit.
背景技术Background technique
当施工区域内地下水丰富，建筑物基础均坐在淤泥质粉质粘土层上，而且很多设备基础埋设深度较大，且部分基础周围环境复杂、均有建筑物，采用大开挖施工完全不可能。拉森钢板桩进行基坑支护，拉森钢板桩施工处理深度大、施工时对相邻建筑物影响小、能克服许多环境困难、施工速度快等优点得到充分显示，钢板桩入土深度除保证本身的稳定性外，还应保证基坑底部在施工期间不会出现隆起和管涌现象。在软土中开挖较深的基坑，当桩背后的土柱重量超过基坑底面以下地基土的承载力时，地基的平衡状态受到破坏，常会发生坑壁土流动，坑顶下陷，坑底隆起的现象。When the groundwater in the construction area is rich, the building foundations are all sitting on the muddy silty clay layer, and many equipment foundations are buried deeply, and the surrounding environment of some foundations is complex and there are buildings, it is completely impossible to use large excavation construction . Larsen steel sheet piles are used for foundation pit support. The advantages of Larsen steel sheet piles are large construction treatment depth, little impact on adjacent buildings during construction, can overcome many environmental difficulties, and fast construction speed. In addition to its own stability, it should also ensure that the bottom of the foundation pit will not bulge and pipe during construction. When excavating a deep foundation pit in soft soil, when the weight of the soil column behind the pile exceeds the bearing capacity of the foundation soil below the bottom of the foundation pit, the balance of the foundation will be destroyed, and the soil on the pit wall will often flow, the pit roof will sink, and the bottom of the pit will sink. uplift phenomenon.
发明内容Contents of the invention
本实用新型主要是针对现有技术所存在的结构复杂，施工成本较高，易漏水，开挖量较大，地基平衡易受破坏等的技术问题，提供一种结构简单，施工成本较低，不易漏水，开挖量较小，地基平衡不易受破坏的加筋钢板桩基坑。The utility model mainly aims at the technical problems existing in the prior art that the structure is complex, the construction cost is high, water leakage is easy, the excavation volume is large, and the foundation balance is easily damaged, etc., and provides a simple structure, low construction cost, The reinforced steel sheet pile foundation pit is not easy to leak, the excavation volume is small, and the foundation balance is not easily damaged.
本实用新型的上述技术问题主要是通过下述技术方案得以解决的：加筋钢板桩基坑由打入基坑内的钢板桩围成，基坑两侧设置有钢板桩，钢板桩之间设置有钢管支撑，钢管支撑水平横置在基坑口上，且两端分别连接两个钢板桩，钢管支撑的两端头上分别设置有端头板，基坑底部设置有排水沟，排水沟之间埋设有固定钢块，固定钢块上焊接有斜撑筋，斜撑筋的另一端伸向端头板并固定。端头板利用螺栓将H型钢连接而成，具有组装方便，现场装配简单，根据不同的基坑按设计要求进行组合和连接，可重复使用，在支撑杆件上能安装各种检测仪器进行施工检测。The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: the reinforced steel sheet pile foundation pit is surrounded by steel sheet piles driven into the foundation pit, steel sheet piles are arranged on both sides of the foundation pit, and steel sheet piles are arranged between the steel sheet piles. Steel pipe support, the steel pipe support is placed horizontally on the opening of the foundation pit, and two steel sheet piles are connected at both ends, the two ends of the steel pipe support are respectively provided with end plates, and the bottom of the foundation pit is provided with drainage ditches, and the drainage ditches are buried There is a fixed steel block, and a diagonal brace is welded on the fixed steel block, and the other end of the diagonal brace extends to the end plate and is fixed. The end plate is made by connecting H-shaped steel with bolts. It is easy to assemble and assemble on site. It can be combined and connected according to the design requirements of different foundation pits. It can be used repeatedly. Various testing instruments can be installed on the supporting rods for construction. detection.
因此，本实用新型具有设计较合理，施工成本较低，不易漏水，开挖量较小，地基平衡不易受破坏等特点。Therefore, the utility model has the characteristics of more reasonable design, lower construction cost, less water leakage, less excavation volume, less vulnerable foundation balance and the like.
