施工安全防护措施补充方案
根据2005年4月14日在我项目部召开的会议精神，并结合各站段所提出的具体防护要求，为确保跨铁路施工的安全，对原上报施工方案中安全防护措施不足之处进行以下补充:
一、站场内：
1、认真组织各级作业人员学习铁路营业线施工安全管理规定，制定跨线作业区域操作规程，培训学习有关封闭作业要领。
2、施工前,在铁路限界外设置围挡,避免施工过程中的机械设备和材料侵入铁路限界内。
3、施工区两侧距相邻线路中心线不少于3.5m，沿施工区界设置限界栏杆，所有施工作业和人员必须在限界以内施工。
4、施工区采用10cm砼铺面，以保护地下各种铁路设施。
5、进入施工区需拆除A线桥下铁路围墙一段，在拆除围墙处便道侧设置道口看守房，派专人24小时执班，严格执行《铁路道口管理暂行规定》，禁止非施工人员和机械进入施工区。
6、钻孔桩施工时采用长护筒，护筒长度不得小于6.0米。并采用成孔效率高，污染小的旋挖钻进行施工，减少施工振动对铁路产生的影响，泥浆臬置于站场范围以外，钻孔的泥浆采用泥浆车及时清运，防止四处流溢，浸泡道床及路基。
7、承台开挖前，对于靠近铁路侧在4米以内距离的墩位，必须进行固化压浆及钢板桩、钢架挡板板合支护，钢板桩支
Construction of additional security measures for the program
According to April 14, 2005 in my department meeting the spirit of the project, combined with the Stations and the specific protection requirements proposed in order to ensure the safety of inter-railway construction, the original construction plan submitted to inadequate security measures in the following added:
First, stop the venue:
1, operating at all levels conscientiously organize Railway Line to learn the safety regulations, cross-line operations to develop the regional operational procedures, training, learn about the closed operating essentials.
2, before the construction of the railway gauge outside the set Weidang, to avoid construction during the invasion of mechanical equipment and materials within the railway gauge.
3, the construction area from the adjacent line on both sides of the center line of not less than 3.5m, set the gauge along the boundary fence construction, all construction activities and personnel within the construction to be bound.
4, with 10cm concrete pavement construction area to protect the underground variety of rail infrastructure.
5, into the construction area underneath the railway line be removed A section of wall, pavement in removal of the side walls Department crossing guard room set, sent by the 24-hour on duty to strictly enforce the "Provisional Regulations on Management of railway crossing," to prohibit the entry of non-construction workers and machinery construction area.
6, bored pile construction using a long casing, casing length of not less than 6.0 meters. Hole by using high efficiency, less pollution in the construction of auger drilling to reduce the construction impact of vibration on the railway, mud provincial judge placed outside the station, drilling mud with mud truck timely removal, to prevent overspill everywhere, soaking ballast and roadbed.
7, cap before excavation, near the railway side for 4 meters away from the pier spaces, must be solidified grouting and steel sheet piles, steel baffle plate co support, steel sheet pile
