Grout pumps for tunnel boring machine
When applying Leadcrete grout pump, it’s imperative that the correct equipment is used in order to fill all gaps and penetrate into all vacant spaces to give the finished product the required strength, durability and waterproofing qualities.  The correct application of grout is also essential.
When the TBM grouting pump is used in the tunnel boring machine. Grouting on a cement basis represents a tried and tested measure for stabilizing and securing the subsoil and excavated areas. Such injections place high demands on planners and contractors as well as on the mixing and grouting equipment. As a consequence the right choice of machines – the mixing, grouting and registration units for instance – have an important part to play for carrying out grouting projects.
Leadcrete LGH95/165PL-E High Pressure Grouting Pump was used for tunnel boring machine. For the LGH95/ 165PL E High Pressure Grouting Pump, it is a horizontal hydraulic pump used for pumping fluid mixtures, such as cement slurry or bentonite slurry, etc. For injecting in the sub-soil for soil consolidation, piling or even for long transport of material. The equipment adopts two pieces of High Pressure Plungers to stabilize the consistency of the grouting flow. Grouting pressure and displacement is step-less adjustable.
Grout typically comprises a mixture of cement, sand, water with other materials such as fine gravel and accelerating mixtures added on occasion, and it can be a tricky substance to work with unless you have the correct equipment.
There are different types of grout for different applications and each type has unique characteristics including flow rate, setting time and pumping distance. Understanding each of these will aid the selection of the most appropriate pump and production procedure.  For example, pumping distance should always be kept to a minimum and hoses should run as straight as possible, but circumstances don’t always allow for this so it’s crucial to understand the properties of the material and the challenges of each application before making a product selection.
