Definitions

  • a continually elastic curing compound such as a cold curing silicone caoutchouc is used.
  • a compound which has an accelerated curing effect under the influences of moisture is employed.
  • This invention recognizes the fact that when applying such bonding method for water submerged joints, a sufficient bonding will result when the compound is brought into the joint under such pressure that the water is extensively pushed away. The remaining moisture of the pores later on reacts with the compound and effects its complete curing within short time intervals. Afterwards, the bonding of the compound is so strong that it stands even stronger dashes of the waves in a storm. Also, the extensions and compressions caused here by the working of the interlocking joints remain without influence. Besides, in many cases neither for the purpose of tightening nor for positioning, the curing strip is a bonding actually required.
  • This form-fitting bonding is given in narrow clefts by the roughness of the surfaces.
  • the strong curving of the joint in the direction transversal to the wall plane acts in a sense of a form-fitting positioning of the compound strip in the joint. It is especially advantageous to use the method according to this invention with joint shapes which are narrowed in the direction of the tightening.
  • the already mentioned characteristic of the elasticity of the compound cured in the joint is important in two concerns. Firstly, the compound should be able to yield to relative movements of the two joint walls facing each other and secondly, the elasticity of the compound should make possible the pressing of the compound strip under the prevailing differential pressure into the narrowing of the joint and therewith the desired tightening effect.
  • the compound may be injected into the joints to be tightened with well known equipment.
  • injection it is understood to be a method by which the liquid or viscous compound is extruded out of a nozzle directed to the joint under such pressure as to make it penetrate into it sufficiently deep.
  • the viscosity of the compound during the injection process should be low enough to enable it to penetrate into the joint deep enough under the prevailing conditions but also large enough so as not to be rinsed out of the joint under the influence of gravity or under the influence of differential pressures which might become active during injection.
  • Lugatolastic registered trade mark
  • silicone caoutchouc basis by Lugato Chemie & Co., Hamburg 70.
  • the compound is injected under water from the pressure side into the joint. After injection and before curing the water pressure then has an effect in the sense of pushing the compound further into the joint. If it is feared that the water pressure might be too heavy so that the compound might be pressed out of the joint at its inner side again, the water pressure may be screened off for a time until curing of the compound by any suitable means, for instance by adhesive strips which are applied outwardly to the joint immediately after injection and which need only to have a limited durability. In any case, especially at higher differential pressures, it is advantageous to use a very fast curing compound.
  • the indication of the compound strip cured in the joint as a substantially form-stable body means that this body possesses such an internal coherence that it may not be pressed out of the joint which has to be tightened, under the differential pressures which have to be expected.
  • Preferred are those compounds which solidify to a permanently elastic body, but in many cases, also permanently plastic compounds are employable if they solidify from the originally liquid or viscous condition to a toughness great enough to be kept inside the joint under the prevailing conditions in consequence of the form-fitting cooperation with the joint.
  • FIG. 1 illustrates a joint in cross-section, which is to be tightened in accordance with this invention
  • FIG. 2 shows a cross-sectional view through the connected edges of two steel sheet piles with an apparatus applied for the injection filling the joint;
  • FIG. 3 is an elevational view of the apparatus of this invention in direction III as shown in FIG. 2, and
  • FIG. 4 is an elevational view of the apparatus in direction IV as shown in FIG. 2.
  • two wall forming elements 1 and 2 form a joint 3 on which from side 4 is a water pressure indicated by arrows. On the other side 5, lower or no water pressure is effective.
  • the joint 3 narrows from side 4 to side 5. It is partly filled out by a strip 6 of permanently elastic compound which is cured inside the joint and has been pressed into the narrowing of the joint 3 by the pressure effective on side 4, and therethrough is kept even so that it should undergo no sufficient bonding with the walls of joint 3. It is pressed tightly against the joint surface so that a good tightening is achieved.
  • FIG. 2 shows the edges of two steel sheet piling elements 8 and 9 facing each other and connected to each other by lock 7.
  • an interlocking joint 10 which is to be tightened.
  • a device suitable for this purpose is indicated in a purely schematical drawing at 11. It consists of a carrier frame 12 to which magnets 13 are fastened facing the steel sheet piling and which may be permanent or electro-magnets. Further provided are wheels 14 on which the device is drivably mounted along the steel sheet piling. The magnets 13 are adjusted in a manner so that there remains only a small interstice 15 between them and the steel sheet piling elements 8 and 9.
  • an injection mechanism 16 is positioned with nozzle 17 which is directed to joint 10 and which is supplied with the compound to be injected via pressure hose 18.
  • nozzle mouth tightening means may be provided preferably in the form of rails effecting the tightening compound which is supplied under high pressure, not to be squeezed out sidewise but to penetrate deeply into the joint.
  • the pins 19 may be fastened on the carrier frame 12 and the steel sheet piling ends seen in the direction of FIG. 2 are in aligned position to nozzle 17 so as to be suitable as guiding means along lock 7.
  • the wheels 14 may be positioned so that under an oblique angle and during forward movement of the apparatus a continuous lateral power component originates which presses the nozzle, the pins and/or the tightening rails against the edges of the joint to be tightened.
  • Magnets 13 are provided which are dimensioned strong enough to keep the device attached to the steel sheet piling also under the highest forces which might occur during the injection process. I
  • the device is provided on its upper side with cars 20 to which a chain 21 or a rope is fastened which leads to a winch.
  • a watching hole 22 is provided in the plate 12 .
  • Means may also be provided so as to de-rust the joint and/or the area in which the rollers 14 are runnmg.
  • the invention operates in the following manner:
  • the apparatus While suspended in a winch the apparatus will be attached to the steel sheet piling 8, 9 in such a way that the guiding means fix the nozzle mouth in the correct position in front of the joint. If necessary, the guiding means and respectively, the nozzle 17 are adjusted to their correct position after the magnets 13 have been switched on the device and are attracted against the steel sheet piling by the originated magnetic field.
  • the device When suspended by the winch, the device may be moved up and down on the steel sheet piling.
  • the diver accompanying the device may only have to supervise its function.
  • the working speed will be adjusted so that a sufficient filling of the joint is warranted. It may be automatically controlled by the pressure by which the compound is supplied to the nozzle.
  • a method of tightening a joint defined between facing walls of forming elements that lie adjacent each other and are submerged in water comprising the steps of a. injecting a permanently elastic compound, in a liquid form and under pressure into the joint along the length thereof; said pressure being sufficient to push the water from the joint and the facing walls of the forming elements in the area of which the compound is injected; and
