Description
Parameters
The single-cutter earth pressure balance pipe jacking machine can be used in both soft and hard soils. It is a pipe jacking machine for all soils. The depth of the soil is not high, and the minimum is 1.5 times the pipe diameter. Through a reasonable grouting method, the soil can be improved and the ground settlement of the control surface stabilizer can be maintained. The deformation is extremely small, the transportation and handling of the spoil is convenient and simple, the working environment is good, the operation is safe and convenient, and it is suitable for large-diameter and long-distance pipe jacking.
 
Technical features:
 
1. It is suitable for a wide range of soil quality: not only suitable for all kinds of soil, but also for medium coarse sand, strong weathered and medium weathered sandstone;
 
2. Using low-speed and large-torque transmission mode, the cutting force of the cutter head is high, and the overload coefficient can reach more than 3;
 
3. There is an independent and complete soil water injection and grouting system, which can improve the soil of the excavation surface, thereby expanding the scope of application;
 
4. The construction ground settlement is small, and the minimum composite soil layer is only 1.5 times the pipe diameter;
 
5. It adopts a center-supported cutter head, which has compact structure, light weight, long service life and convenient maintenance;
 
6. Unearthed by screw conveyor, the unearthed height is high and the particle size is large;
 
7. The correction angle is 2.5 degrees, and the nose pitch and weave rotation adopt advanced control system, which can be digitally displayed, easy to operate, sensitive in action, intuitive and reliable;
 
8. Full-face cutting, full opening rate, realistic earth pressure.
 
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。
