The AMT series is an auxiliary piling equipment primarily designed to support trenching, foundation construction, drilled foundation work, and trench less foundation machinery. It effectively controls the sand content and particle precision in the slurry during, construction, achieving solid-liquid separation of solid particles in the slurry and discharging, dewatered waste residue. This process enhances pile hole formation rates, reduces the cost of slurry used in construction, and slurry recycling.
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.
The RJP-3.0 Method realizes real-time monitoring and regulation of construction parameters through the jet drilling real-time measurement system, addressing the drawback of lacking key parameters in traditional jet grouting technology. It can simultaneously acquire basic parameters such as nozzle holder lifting speed, rotation speed, nozzle diameter and quantity, air pressure, slurry flow rate, and pump outlet pressure. It achieves real-time drilling deviation monitoring and dynamic collection of downhole pressure inside and outside the drill pipe, assists in analyzing the actual kinetic energy of the slurry and inferring the pile diameter, and forms a closed-loop control system by integrating post-construction deviation data. This significantly improves the preparation accuracy of the soil-cement mixture and construction reliability.

Pipe jacking-maskiner bruger skjoldteknologi til at udgrave jord eller sten med et roterende skærehoved og fjerner det udgravede materiale via et muddertransportsystem, mens hydrauliske donkrafte skubber præfabrikerede rør ind i tunnelen, og injektionsmørtel stabiliserer væggene.
Disse maskiner anvendes i forskellige kommunale og civile projekter, herunder bygning af underjordiske vandforsynings-/afløbssystemer, installation af gasrørledninger, optiske kabler og konstruktion af metrotunneler, hvilket minimerer forstyrrelsen af overfladen.
Med hensyn til typer passer gyllebalancemaskinen til forskellige jordbunds- og grundvandsforhold; jordtryksbalancemaskinen er til blød til mellemhård jord; og klippemaskinen, der er udstyret med kraftige værktøjer, er til klippeformationer og endda blandede jord- og klippeforhold. De er nøglen til moderne underjordisk byggeri.
