Application:
1. The grout pump can be used to grout cement paste,mortar and
other liquid(partical size ≤3mm) . Medium temperature is between
5-8℃. The water cement ratio of solid- liquid mixture should be
0.75 or higher. The maximum output pressure should be 4Mpa, and
work flow 3.6 m³/h.
2. The grout pump is widely used pressure grout in tunnels, coal
mine, bridges and dams, building foundation, and other underground
projects.
The double-fluid grouting process is a development and a new
breakthrough on the basis of grouting reinforcement of soft soil
foundation. This process overcomes the soil disturbance and
softening effect caused by the grouting reinforcement process. It
has achieved good results in controlling the settlement caused by
underground construction and excavation under overloaded ground,
and can greatly shorten the soil settlement stabilization time.
Working principle:
Double-liquid grouting mainly has the characteristics of overcoming
the disturbance and softening effect caused by grouting
reinforcement, shortening the consolidation settlement, and
controlling the settlement. Therefore, when the two-liquid grouting
is filled into the voids in the soil, especially the gap caused by
construction machinery, as the grout has the characteristics
of rapid setting and initial setting in an instant, it can play a
role of strengthening and reinforcement.
At the same time, the loss of grout is small and the effective
filling amount is increased during the grouting process, which can
supplement the problems caused by many reasons of soil
loss. Limit the displacement of the foundation activity,
and reduce the ground settlement before it affects the building
structure. At the same time, when the gap in the filled soil
reaches a certain degree of saturation, the double-liquid pump will
gradually spread under the pressure to continuously fill the gap,
which can squeeze the surrounding soil and split the weak parts of
the soil to form a cross-network solidification body, enhance
the compactness and compressive modulus of soil, expand the stress
field, improve the bearing capacity, and thus greatly reduce the
final settlement.
Features:
1. ZBS 3.6/4-5.5 double liquid grout pump is a single cylinder
double action piston pump, which can work in inflammable and
explosive sites, dusty amd rainy environment, or other bad
condition.
2.The pump has simple structure, light weight, small size, reliable
performance, high pumping pressure.
