　　防护雕栏应由高低横杆和雕栏柱构成。上杆离地高度为1.0~1.2m，下杆离地高度为0.5~0.6m。坡度大于1：2.2的程度，护栏应高1.5m，并加设菜园子菠菜论坛 。除设想计较外，当横杆长度大于2m时，必须加设雕栏柱。

　　The protective railing shall be composed of upper and lower rail and railing column. The upper rod is 1.0-1.2 m above the ground, and the lower rod is 0.5-0.6 m above the ground. If the slope is greater than 1:2.2, the guardrail should be 1.5m high and a safety net should be added. In addition to the design calculation, when the length of the crossbar is greater than 2m, the railing column must be added.

　　雕栏的安稳应适合以下请求：

　　The railings shall be fixed according to the following requirements:

　　基坑四周安稳时，可用钢管打入公开50~70cm深。钢管与边缘的间隔不应小于50cm。在基坑四周利用钢板桩时，可以或许在钢板桩的外侧打入钢管。

　　When the foundation pit is fixed around, the steel pipe can be used to drive into the underground 50~70cm deep. The distance between steel pipe and edge should not be less than 50cm. When steel sheet piles are used around foundation pits, steel pipes can be driven into the outer side of the steel sheet piles.

　　安稳在混凝土地板、屋顶或墙壁上时，预埋件可用钢管或钢筋焊接安稳。利用竹木雕栏时，可在预埋件上焊接30cm长∟50×5角钢，并在高低两侧钻孔，而后用10mm螺栓将竹木件安稳。

　　When fixed on concrete floor, roof or wall, the embedded parts can be welded firmly with steel pipe or steel bar. When using bamboo railings, weld 30cm ∟50×5 Angle steel on the embedded parts, drill holes on the upper and lower sides, and secure the bamboo and wood parts with 10mm bolts.

　　在砖块或砌块等砌体上安稳时，可事后搭好规格适合的80×6曲折扁钢作为预埋铁的混凝土砌块，而后按上述方式安稳。

　　When fixed on masonry such as bricks or blocks, 80×6 bending flat steel of suitable specifications can be pre-built as concrete blocks with embedded iron and then fixed in accordance with the above method.

　　雕栏立柱的安稳及其与程度面的毗连，全体布局应使护栏在上杆上的肆意地位，可以或许蒙受任何标的目的1000N的外力。当雕栏地位轻易产生拥堵、车辆撞击或物体碰撞等环境时，应增添雕栏截面或加密柱间距。

　　The railing column is fixed and connected with the horizontal plane. The overall structure should make the guardrail at any position on the upper pole and be able to withstand the external force of 1000N in any direction. When the position of the railing is prone to congestion, vehicle collision or object collision, the section of the railing or the spacing of the column should be increased.

　　白菜彩金社区菜园子 必须自上而下用竖网封锁，或在雕栏下设置高度不小于18cm的慎密安稳的护脚板或高度40cm的护脚板。若是护趾板和护栏有孔洞，则不应大于25mm。板与围栏底部之间的空隙不应大于10mm。领受台两侧的雕栏必须自上而下用竖网或竹栅栏吊挂。

If the toe guard and guardrail have holes, they should not be larger than 25mm. The gap between the plate and the bottom of the fence should not be greater than 10mm. The railing on either side of the receiving station must be hung from top to bottom with vertical nets or bamboo fences.
