Underground construction drilling machinery

Underground diaphragm deep wall  machine ,engineering construction machinery refers to the  drilling equipment used for the construction of underground

 diaphragm wall comstruction  underground diaphragm wall is used for supporting excavation and retaining soil underground structural 

components. These walls are typically built using a combination of drilling, excavation, and concrete pouring techniques.

Machinery used for diaphragm wall construction includes:

Continuous Wall grabbers: These are large hydraulic grabbers used to dig soil and create grooves for the continuous wall. 

The grab is attached to a crane or excavator and is able to dig to the desired depth and width.

Sand removal plants: These plants are used to remove excess soil and moisture from excavation materials. 

They consist of a series of screens and cyclones that separate the soil from the water, allowing for the reuse of excavated materials.

 Bentonite mixing plant: Bentonite is a kind of clay that is used as drilling fluid in continuous wall construction. 

The bentonite slurry is mixed and prepared by the bentonite mixing station, and then pumped into the ditch to stabilize 

the soil and support the excavation.

 Concrete mixing plants: These mixing plants are used for mixing and preparing concrete for the construction of continuous walls.

 The concrete is usually mixed on site and then pumped into the ditch with a concrete pump.

Tremi pipes: Tremi pipes are long, flexible pipes used to pour concrete into the trench. The pipe is inserted into a trench

 and the concrete is dumped from the bottom, allowing continuous and even dumping.

 Continuous wall cutting machine: These machines are used to cut and shape continuous wall panels. 

They are usually attached to cranes or excavators and are capable of cutting hardened concrete.

 Anchoring systems: Anchoring systems are used to provide additional support and stability for continuous walls.

 These systems typically consist of steel bars or cables anchored in the surrounding soil or rock.
