基坑护栏的基本组成有哪些?
大型基坑甚选用地下连续墙和柱列式钻孔灌注桩连锁等办法,防护外侧土层坍入;在邻近修建无影响者,可用井点法降低地下水位,选用放坡明挖;在冰冷地区可选用天然凉气冻结法开挖等等。
Large foundation pits even use methods such as underground continuous walls and column type bored pile interlocking to prevent the collapse of the outer soil layer; For those who are not affected by nearby construction, the well point method can be used to lower the groundwater level, and slope excavation can be used; In cold regions, natural cold gas freezing method can be used for excavation, and so on.
关于跨越必定规划的危险性较大的分部分项工程,施工单位应当组织对专项方案进行证明。基坑护栏由防护网片和立柱组成。基坑围挡护栏防护网片由2cm×4cm方管焊接组成。
The construction unit should organize experts to prove the special plan for high-risk sub projects that cross certain planning. The foundation pit guardrail is composed of protective mesh and columns. The protective mesh of the foundation pit fence is made of 2cm × Composed of 4cm square tube welding.
单片规范1.1米×1.7米,两端设有跨耳用Φ10螺栓与立柱联接固定,每个法兰盘设4个螺栓孔、顶部封闭,与地上用Φ14膨胀螺栓固定。
Monolithic specification 1.1 meters × 1.7 meters, with cross ear use at both ends Φ 10 bolts are connected and fixed to the column, and each flange is equipped with 4 bolt holes and the top is closed, which are used to connect with the ground Φ Fix with 14 expansion bolts.
设备后,护栏上边与立柱平齐,下边距地上20cm,两立柱间隔2米。所运用原资料均选用规范资料,制作严峻按图施工,规范正确,焊接点健壮,抵达防护之目的。
After the equipment is installed, the upper edge of the guardrail is flush with the column, and the lower edge is 20cm above the ground, with a distance of 2 meters between the two columns. All the raw materials used are selected from national standard materials, which are strictly constructed according to the drawings, with correct specifications and robust welding points, achieving the purpose of safety protection.
