JMP Method (Micro-disturbance Ultra-high Pressure Jet Mixing Pile) utilizes ultra-high pressure water for hole forming, with cement slurry performing secondary cutting and mixing with soil. The drill bit's opening-closing blades actively stir and apply incline reverse pressure, while strictly monitoring multiple process parameters. It adopts underground pressure early warning and in-hole slurry discharge technologies to achieve omni-directional foundation reinforcement.
The KR300ES is a specially designed low headroom rotary drilling rig ideal for working under height-restricted environments such as bridges, tunnels, and indoors. With powerful torque and compact structure, it delivers efficient deep foundation drilling without compromising performance or safety.
Boremaskinen med omvendt cirkulation er velegnet til store diametre, ultradybe eller klippefyldte pæle og andre komplekse geologiske forhold i forbindelse med borekonstruktion. Den bruges i vid udstrækning til at bore pælefundamenter til store bygninger, havne, kajer, dæmningsbeskyttelse, broer, offshore-vindkraftværker og så videre. Det er et alternativt produkt til andet pæleudstyr.

The single roler bit is composed of a single cone and a lug matched by a bearing.According to different strata and construction requirements, different cutting struclures can be selected; wear resistant carbide are welded and cemented carbide inserts are inserted on the back of the lug.
Den roterende borerig får akslen til at rotere og udøver et positivt tryk, så den roterende borekrone kan ramme, rulle og klippe klippen. Knus klippen for at danne en knusende ringzone, knæk derefter den midterste søjle ved at svinge skaftet og tag den knækkede søjle ud for at danne et hul.
