In all aspects, the threaded steel is superior to other materials.
所述掘进杆前端出水口2的直径小于掘进杆1的内径，水流从掘进杆前端出水口2处喷出时水流压力增大，可对土壤产生冲击力，掘进杆后端设有连接丝口16，可根据需要在掘进杆后端的连接丝口16处承插所需长度的加长杆，以适应不同距离过道场所所需长度，连接丝口16处也可连接进水软管。The diameter of the water outlet 2 at the front end of the driving rod is smaller than the inner diameter of the driving rod 1. When the water flow is sprayed from the water outlet 2 at the front end of the driving rod, the pressure of the water flow increases, which can generate impact on the soil. 16. An extension rod of the required length can be inserted into the connecting wire port 16 at the rear end of the driving rod as required, so as to adapt to the required length of the aisle places with different distances. The connecting wire port 16 can also be connected to the water inlet hose.

The galvanized steel pipe has strong bending and torsion resistance. Considering safety, operability and other mechanical properties, the material of the tunneling rod 1 is galvanized steel pipe. During the jacking process, there is basically no cohesive force between the pipe surface and the soil. There is no dead pipe in the middle, and the galvanized steel pipe has strong corrosion resistance and long service life.
进行使用时，将固定座11放置平稳，拧松调节销13，根据需要调节上下调节杆，改变底座的高度，确定好高度后拧紧调节销13，使其固定在此高度上，之后将掘进杆1水平放置在半圆形卡槽8内，拧松掘进杆转动装置上的固定销6，使套管4可在掘进杆1上滑动，拉开套管4与半圆形卡槽8的距离后，拧紧固定销6，使套管4上的摇杆7与掘进杆1同步转动，掘进钻头3也随之转动，搅动待穿孔的土壤。在掘进杆1的后端连接水源或进水软管，打开压力水阀17，水流通过掘进杆前端出水口2处喷出，因掘进杆1前端的管口直径缩小，增大了水的压力，所以从掘进钻头3内喷出的水对待穿孔的土壤产生冲击力，减小掘进难度，配合掘进钻头3的转动，即实现快速的穿孔掘进。When in use, place the fixing seat 11 stably, unscrew the adjusting pin 13, adjust the upper and lower adjusting rods as required, change the height of the base, and tighten the adjusting pin 13 after determining the height to fix it at this height, and then install the driving rod 1 Place it horizontally in the semicircular slot 8, unscrew the fixed pin 6 on the driving rod rotation device, so that the casing 4 can slide on the tunneling rod 1, and open the distance between the casing 4 and the semicircular slot 8 Finally, tighten the fixed pin 6 to make the rocking bar 7 on the sleeve pipe 4 rotate synchronously with the driving rod 1, and the driving bit 3 also rotates thereupon, stirring the soil to be perforated. Connect the water source or water inlet hose at the rear end of the driving rod 1, open the pressure water valve 17, and the water flow will be sprayed out through the 2 water outlets at the front end of the driving rod 1, because the diameter of the nozzle at the front end of the driving rod 1 is reduced, increasing the pressure of the water , so the water ejected from the tunneling bit 3 produces an impact force on the perforated soil, reducing the difficulty of tunneling, and cooperates with the rotation of the tunneling bit 3 to realize rapid perforation tunneling.
