Parameters
The single-push disc earth pressure balanced pipe jacking machine can be used in soft soil and hard soil, and it is an all-earth pipe jacking machine. The depth of the compound soil is not high. The minimum diameter is 1.5 times the diameter. Through reasonable grouting, the soil can be improved and the ground subsidence of the stabilizer on the control surface can be maintained. Minimal deformation, convenient and simple transportation and disposal of spoil, good working environment, safe and convenient operation, suitable for large diameter and long distance pipe jacking.
 
Technical characteristics:
 
1. Suitable for a wide range of soils: Not only for various soils, but also for medium coarse sand, strong weathering, and weathering sandstone;
 
2. It adopts low-speed and high-torque transmission method, the cutter head has high cutting force, and the overload coefficient can reach more than 3;
 
3. There is an independent and perfect soil water injection and grouting system, which can improve the soil on the excavation surface, thereby expanding the scope of application;
 
4. The construction ground settlement is small, and the minimum soil layer is only 1.5 times the pipe diameter;
 
5, using a center-supported cutter head, compact structure, light weight, long life, easy maintenance;
 
6. Unearthed by screw conveyor, with high unearthed height and large particle size;
 
7. Deviation correction angle is 2.5 degrees, and the head's pitch and knitting adopt advanced control system, which can be displayed digitally, easy to operate, sensitive in action, intuitive and reliable;
 
8. Full face cutting, full opening rate, earth pressure is realistic.
 
单刀盘土压平衡顶管机在软土、硬土中都可采用,是全土质的顶管掘进机。复土深度要求不高,最小为1.5倍管径、通过合理的注浆方式,可以改良土体,保持控制面稳定剂地面沉降。变形极小,弃土的运输和处理方便、简单、作业环境好,操作安全、方便,适合大口径、长距离顶管。  技术特点:  1、适合土质范围广:不仅适用于各种土质,而且适用于中粗砂、强风化、中风化砂岩;  2、采用低速大扭矩传动方式,刀盘切削力度高,过载系数能达到3以上;  3、有独立、完善的土体注水、注浆系统,可对挖掘面土体进行改良,从而扩大适用范围;  4、施工地面沉降小,复土层最小仅为管径的1.5倍;  5、采用中心支撑式刀盘,结构紧凑,重量轻,寿命长,维修保养方便;  6、采用螺旋输送机出土,出土高度高,粒径大;  7、纠偏角度2.5度,机头的仰俯和编转均采用先进的控制系统,可数字显示,操作方便,动作灵敏,直观可靠;  8、全端面切削,开口率满,土压力跟切合实际。
