Shallow U-shaped sandstone riverbed steel trestle guide hole construction method
The invention provides a shallow U-shaped sandstone riverbed steel trestle guide hole construction method. The method comprises the following steps of S1, manufacturing a steel platform according to agradient and water depth of a bottom of a riverbed; S2, measuring a guide hole position, hoisting the steel platform to the guide hole position, leveling the steel platform, and fixing the steel platform in the riverbed; S3, after the steel platform is positioned and leveled, mounting and fixing a drilling machine at the drilling hole of the steel platform; S4, starting a drilling machine, carrying out trial operation, then carrying out slow sinking, and then drilling to a designed depth; and S5, hoisting away the drilling machine, then hoisting a large steel pipe, and inserting the large steel pipe into the drilled hole and fixing in place. Problems that a shallow U-shaped sandstone riverbed and a large machine tool are not high in economical applicability, traditional punching equipmentcannot achieve accurate positioning, and a vibration hammer cannot sink are solved, the method is particularly suitable for the U-shaped shallow with the uneven riverbed bottom of the hard riverbed of a village and town river, the steel platform is convenient to move, the hole guiding speed is high, the economic practicability is high. and a construction period is saved.
本发明提出了一种浅滩U形砂岩河床钢栈桥引孔施工方法，包括如下步骤：S1、根据河床底部坡度水深，制作钢平台；S2、量出引孔位置，吊放钢平台至引孔位置，调平钢平台并使钢平台固定在河床中；S3、在钢平台定位调平后，将钻机安装在钢平台的钻孔孔洞处并固定；S4、启动钻机，试运行然后缓慢下沉，随后钻孔到设计深度；S5、吊离钻机，再吊装大钢管，将大钢管插入钻孔中并固定到位。本发明解决了浅滩U形砂岩河床，大型机具经济适用型不强，传统冲孔设备无法精准定位，振动锤无法下沉等难题，本发明特别适用于乡镇河流河床坚硬的河床底凹凸不平的成U字型的浅滩，而且钢平台移动方便，引孔速度快，经济实用性强，节约工期。
