Earth Pressure Balancing(EPB)Pipe Jacking Machine
發布時間：2018-04-26
D1型土壓平衡頂管機在軟土、硬土中都可采用，是全土質的頂管掘進機。覆土深度要求不高，最小為1.5倍管徑，一般管徑在φ1500-φ4000mm之間，通過合理的注漿方式，可改良土體，保持控制面穩定及地面沉降。變形極小，棄土的運輸和處理方便、簡單，作業環境好，操作安全、方便，適合大口徑、長距離頂管
The D1 EPB pipe jacking machine can be used in wide and all-range soil conditions, with either soft or hard soil.The covered depth of the pipe is minimally 1.5X the pipe diameter, while the pipe diameter is generally between 1500 to 4000mm. With shield outside lubrication, soil paste in the excavation chamber could have the equal support pressure to the surrounding soil and groundwater, so as to achieve an improved balance. With the aforesaid Soil Improvement, the risk of heave or settlement at the surface when advancing can be minimized.
Therefor the EPB Pipe Jacking Machine can minimize the ground deformation, improve the efficiency of soil conveying and excavation. The operational environment is better runand the advancing process is safer.
The EPB technology is suitable for large diameter and long distance pipe jacking.
土壓平衡頂管機技術性能與特點：Technical Performance Characteristics
1.適用土質范圍廣，適用于從N值接近0的粘土至N值為50的砂礫卵石地形，對于透水性較高的砂層，進行土體改良后形成螺旋輸送機土塞效應亦可進行有效施工。
The EPB Pipe Jacking Machinecan be used in a wide range of soil conditions. It is applicable to sandy, gravel and pebbly topography from clay with N value close to 0 to 50. For sand layer with higher permeability, advancing is viable with the Soil Improvement and the consequent plug effect of the screw conveyor.
2.采用低速大扭矩傳動方式，刀盤切削力較高，過載系數能達到3以上
The EPB Pipe Jacking Machineadopts low speed and high torque transmission method, with which the cutting force of cutter is strengthened and the overload coefficient can exceed 3.
3.有獨立、完善的土體注水、注漿系統，可對挖掘面土體進行改良，從而擴大適用范圍
The EPB Pipe Jacking Machine comprises a separate slurry injection and shield outside lubrication system, to facilitate the Soil Improvement and hence to widen the range of the soil conditions where the it operates.
4.施工地面沉降小，復土層最小僅為管徑的1.5倍
The ground settlement is small, and the covered depth of the pipe is as small as 1.5X the pipe diameter.
5.采用中心支撐式刀盤，結構緊湊，重量輕，壽命長，維修保養方便
The EPB Pipe Jacking Machinehas a centralized supporting cutter plate, and thus has a compact and light weightedstructure, a long service life with easy maintenance requirement.
6.采用螺旋輸送機出土，出土高度高，粒徑大
The EPB Pipe Jacking Machineexcavates soil by the screw conveyor with a high excavation power.
7.糾偏角度2.5°，機頭的仰俯和偏轉均采用先進的控制系統，可數字顯示，操作方便，動作靈敏，直觀可靠
The EPB Pipe Jacking Machineuses an advanced control system in head bending and deflection with a Correction Angle of 2.5 °with digital display, which is easy to operate and turn. This makes the machine more reliable in advancing.
