The works consisted of installing temporary propping throughout the structure core-wall supports, which went across 4 levels of back-propping, hydraulic jacking the temporary works and pre-stressing of the tension bars to ensure the suppoort of structure was maintained during demolition and steelwork installation works.
Hydra Capsule were able to offer 24/7 serivce to ensure the loadings were correctly distributed throughout the structure and in addition we supplied competent engineers for crash-deck installation. Offering the main contractor a "one-stop" solution for all their requirements during the 3 months constructions works.
Due to Hydra Capsule continuing development and investment within the flat jacking, hydraulic jacking & monitoring equipment and temporary propping equipment sections. We are proud to release technical data information for all our current clients and engineers for on-going and future projects.
The information consist of our ever-growing 'hire fleet' of hydraulic jacks, pressurising and pumping equipment and lifting equipment which excess over 1,000 items readily avaliable for hire within 24 hours. In addition, Hydra Capsule have progressed into offer ingcomplete contractual service packages, ranging from flat jacks, temporary propping systems with intregrated jacking and remote geotedic monitoring system to become a leading company for an "one-stop solution".
Detailed on the technical data and information can be found on our 'Downloads' page.
Hydra Capsule have supplied in excess of 60 number 200 tonnes and 20 number 100 tonnes x locking collar hydraulic jacks with associated pressurising and pumping equipment (15 number hydraulic hand and electric pumps) to assist with the installation and sliding of the new bridge decks and support beams over a 12 weeks period.
In total over 200 number items were supplied ranging from hydraulic hoses, pressure gauge, manifold adaptors, hydraulic electric and hand pumps and hydraulic cylinders.

Hydra Capsule were awarded the subcontract to supply and fix approximately 65 number x grout-filled flat jacks. The flat jacks were used to pre-load excavation support struts ranging from 40 tonnes upto 900 tonnes to assist with ground works to be completed.
In additon, a load transfer for the complete southside wall of the V&A Museum was completed, which in turn weighed 400 tonnes and was synchronuously lifted across 30 number hydraulic jakcs, accurate to +/- 0.10mm throughout the jacking operation. The jacks were then transferred with cementitious grout for permanent in-situ application, maintaining existing movement and load accuracy ranging from 0.25mm and +/- 5 kNs at each jacking location.
Hydra Capsule recently supplied a hydraulic jacking and monitoring system for transferring a newly constructed bridge worth £5.5 million near the Manchester Airport. The huge 1,500-tonne structure was approximately 100 metres in length, was built beside the motorwar and then transported and lifted into position.
The project to install the new bridge is one of 121 in the Government's two-year £300m improvement scheme by improving road safety and tackling congestion bottlenecks.
The works involved using a mixture of 200 tonnes and 360 tonnes hydraulic jacks, interlinked pumping sets, controlled by individually synchronous pumps. With real-time load and movement monitoring at all the applicable locations. Once the bridge had been positioned. The bridge was lowered onto the hydraulic jacks to transfer the loads for the transportation units.
Once completed, the bridge deck was surveyed and adjusted by the hydraulic jacks to the specified level(s). The cylinders were mechanically locked-off with a screw-thread isolation nut for the installation of the bridge bearings and curing of the supporting plinths.

Hydra Capsule were awarded the contract to supply temporary / permanent transfusion-grout flat jacks to assist the pre-loading of bridge bearings and lifting of the newly installed reinforced concrete beams.
The works involved using single, pairs and sets of grout flat jacks, rated at 50 tonnes, to pre-load newly installed bearings to the correct loads and defined bridge levels for the widening of two bridges.
Initially, the bearings were loaded with temporary fluid (ie. water and/or water) to induce the calcuated bearings loads. Once the defined load and/or uplift had been achieved (uplift of + 2.00mm). The bearings were levelled to accommodate the settlement within the newly cased concrete support piers.
The jacks were monitored for a period of time to observe (if any) movement, settlement and bedding-in occurred. Once these were achieved, the flat jacks was carefully transfused from its temporary state to the permanent grout-filled application. This operation involve gradually injection cementitiuos grout into the flat jacks' capsule, whilst releasing the temporary fluid. Maintaining load and levels throughout the operation.
All works were carried out successfully within traffice managmenet possessions using Hydra Capsule's purposed built digital monitoring and injection system.

Hydra Capsule were approached to design and install 3 number temporary propping support towers at approximately 14 metres high with an integrated hydraulic jacking and monitoring system to accurately pre-load the existing dead loads into the temporary works system. Prior to remedial works being completed on the universal support columns.
The temporary propping was design the accommodate the need to access the column(s) for maintenance inspections and remedial splice modification works. Hydraulic jacks connected with mechanically locking-collars allowed the load transfer to be permanent induced throughout the duration of the project.
In addition, Hydra Capsule supplied access scaffolding to each level of the tower (7 in total per tower), which allowed safe access throughout. All works we completed by our in-house trained and competant personnel.
