Definitions
- the present invention encompasses within the technical sector of the construction of fixed structures in the water, more specifically, to the methods of driving and injection of underwater piles, for the support of marine platforms or equivalent. Background of the invention.
- the solution is suitable for driving piles that have to extend from the bottom to a certain height above the water surface. It is expensive, requires very specialized equipment and poses problems of environmental impacts that can become serious.
- Another way to execute them is to place a vertical guide tube in the same way, rest it on the bottom and insert a tube that will be the final pile inside. Inside this tube a drill head and hoses for water injection are introduced. The boring machine removes the sediments and the water pressure lifts them to the top of the guide tube, from where it leads to deposits or, what is more common, they are poured into the sea. The removal of sediments causes the pile to swell to the expected length, at this time, it is necessary to inject a grout of cement, to join the pile to the ground.
- the bearing capacity of the pile can also be improved by repetitive and selective injections, both at the tip and along the entire shaft.
- the method of driving and injection of underwater piles object of the present invention presents the way to solve the technical problems described above.
- the elements to be used are the vertical tubes or pillars existing in the vertices of the vertical structures supporting the platforms that are to be fixed to the bottom with the foundation and even in the wind turbine tower, if that is what is going to be installed on the platform .
- the method consists of introducing (with an automated procedure detailed below) and during the ground fabrication of the pillars or in the tubes located at the vertices of the tower, a specially designed pile inside each of said tubes. Once the pile is inside the pillar, the tube is closed from the top with a threaded hermetic plug, an O-ring is placed on the pile and a load distribution plug is placed on the O-ring.
- a connecting cable is placed between the two elements that allows them to be recovered later.
- the manufacture of the piles is carried out on land, in an installation attached to that of the manufacturing of the lattice structures, in whose vertical elements they are to be introduced.
- a series of piling tube containers and the following complementary parts arrive to that annexed installation: steel mesh, embedment tubes in the capping, complete flushes and plugs for perimeter injection by the shaft, that is, all the necessary elements for the manufacture of the pile.
- a bridge crane takes a tube and places it on a corner.
- Parallel to the toner there are two guides, one on each side, on which a hydraulic punching head is supported, provided with interchangeable rectangular punches.
- On the punching machine there is a pillar, with sliding plate on a guide, arranged at 90 ° on the pillar.
- At the opposite end of the steer and fixed on the ground there is another equal punching head, with a fixed pillar and support of the horizontal guide.
- In the horizontal guide there is a set of vertical drills all of them, placed on sliding plates and equipped with motorized sprockets, to move on the rack fixed to the guide.
- the free punching machine moves along the parallel guides, to adapt to the length of the pile or recess tube in each case.
- the punching machines located at each end of the tube make a recess each. Simultaneously the drills, which will automatically have been placed in the established position, will perform a set of aligned drills.
- the drills are raised and the punching machine opens to allow the taper, on which the tube is placed, to rotate a certain angle.
- the punching and drilling operation is repeated in the same way as many times as necessary.
- the crane bridge removes the tube and places it on a set of parallel diabolos of varying height and some motorized ones that serve to support and move the tube longitudinally.
- the crane bridge takes a prefabricated steel mesh cylinder that has a diameter smaller than the inside of the tube and places it on the diabolos of varying height; the height is adjusted and they move longitudinally until the mesh is completely introduced into the pile.
- the crane bridge takes another mesh cylinder and places it on the lifting diabolos, these adjust its height to allow the pile with the already installed internal reinforcement to be driven in the opposite direction by the motorized diabolos that support it and introduce them into the outer armor
- the service operator folds the verticals of the mesh, inwards, through the recesses, the crane bridge removes the pile to a storage or storage area and the service personnel places the whip, the perimeter plugs for the injection of the shaft and the O-ring and the rest of the pieces necessary for the driving and injection of the piles.
- the crane bridge places the finished piles on diabolos that propel them until they are fully inserted into the longitudinal tubes that are part of the lattice structure.
- a main pump (flow and constant pressure) sends water from that tank to a regulator. Pressure regulator and variable flow rate flow from the regulator. From that regulator come out as many hoses as piles they want to drive simultaneously. That water hose is screwed up into the plug that we have threaded on the pillar. A water hose is connected to the pressurized water hole and water is introduced into the space between the steel load-sharing cap and the gasket. When the pressure increases, it compresses the joint first and improves the closing of the joint and, as the pressure continues to increase, the piles begin to penetrate the ground.
- the pile has a whip (prefabricated concrete cone with rubber gasket) underneath that facilitates driving.
- the pressure continues to increase and the pile continues to fall, until the pressure that we have to exert, (water pressure) to drive the pile multiplied by the surface of the base of the pile is the load that is desired to hold the pile.
- this way of pile driving has the advantage that the fan itself supposes a sufficient load test that avoids having to oversize the foundation, so that they swell to the necessary and fair height, reducing costs and without detriment of safety.
- this pile driving system has a series of additional advantages such as allowing several piles to be driven simultaneously and that it is a method that does not produce noise, pollution, or turbidity in the water and has no impact. over the sea.
- the closure cap has a hole through which concrete grout is injected.
- the injection system punctual, radial and along the entire shaft.
- the system provides for parallel drilling lines along the entire shaft and separated from each other an arc of circumference of the necessary degrees.
- a plug of hard elastomeric material will have been introduced under pressure into each hole, to which a steel cable will be attached at its base at the opposite end of which has a hook that will be attached to the inner reinforcement of the pile during manufacturing, leaving therefore all the cable inside the pile.
- the inside of the tube is first filled and the pressure continues to increase, until the pressure of insertion of the plugs is exceeded; these, seeing the pressure with which they were introduced, will be shot radially towards the ground by drilling it, dragging the cable together at its base and opening a hole that will be filled with grout armed by the cable and attached to the inner armor and therefore to the reinforced concrete inside the pile.
- the system allows to continue increasing the contribution of grout to the interior of the pile and the pressure to cause the exit to the ground of more grout and therefore increase the area of perimeter consolidation.
- the hook has a plug with a larger diameter than the radial plugs of the shaft and therefore with greater output resistance.
- the plug will fire towards the bottom causing the cables to exit, several in this case and forming an armed bulb, of the desired dimension depending on whether more or less grout If the first case is to say piles without radial injection, the system will work in the same way. If it is necessary to increase the resistance of the shaft and tip, it is enough to perform the described procedures successively.
- the traction plug which is the element where all the tubes are joined at the end, to make the tensile test. Once the test is done, the tubes can be removed, unscrewing the cap and removing the tubes from the top. Thus, all the elements are recoverable.
- the pillar embedment system in the slab or structure is the same (reinforcement tube with reinforcement).
- Using one method or another depends on the relationship between soil resistance and the load to be applied, as well as the seismic activity existing at the installation site.
