Foundation reinforcement issue, urgent!
Thread Content
The injection pumps in our factory have been in use for over a decade; recently, it was discovered that due to severe vibration and lack of maintenance over time, the foundation of these pumps has become hollowed out. The pressure during injection can reach 40 MPa, and if the pumps collapse and the pipelines break, it poses significant safety risks. The new station is under construction, so the pump cannot be shut down for long periods of time. I was wondering if there are any good temporary solutions. Please give me your guidance!
Holes can be drilled at equal intervals around the pump foundation using a water drill, and the voids can be filled with pressure grouting.
Pressure grouting is a good solution; if your factory does not have very high requirements regarding the levelness of the injection pump, you can also create holes in the cement foundation beneath the pump base using two channels or I-beams, and use these solid steel members in place of the original shims. This makes the construction process much simpler, as it allows for various ways of securing the pump in place.
First, address the vibration issue of the pump, as it is the root cause, to prevent the foundation from collapsing prematurely due to vibration. Secondly, depending on the conditions on site, and without affecting operations, the existing facilities shall be used to reinforce the foundation or the pump, with relocation taking place after the new station is built. There are proposals to use grouting; it’s not impossible, but the effect is too slow and the workload is considerable.
Could four shock absorbers be added at the four corners of the pump?
Add shock-absorbing pads, and use angle steel to form a frame to enclose the foundation.
Could you please describe the basic type and damage conditions? It would be best to upload photos.
Temporary emergency measures: 1. Reinforce by pouring in rapid-setting cement； 2. Reinforce the pump’s metal base with shaped steel.
It seems everyone’s opinions are quite similar; thank you. :loveliness:
Holes can be filled with grouting material, which expands slightly and dries quickly. You can give it a try.
