Description

Technical Field

[0001] The present invention belongs to the technical field of marine engineering, and particularly relates to a new type of OMEGA pressing structure that is convenient for installation. Background Art

[0002] The construction of the drainage culvert for the unit by the sectional immersed tube method has been widely used in the project of the nuclear power drainage outlet. Generally, several drainage immersed tubes are prefabricated in a prefabrication yard and transported to the corresponding waterways by floating. The tube sections are docked in the dredged foundation trench that has been completed. At present, flexible joints are mostly used for the immersed tube culvert. The waterproof structure of the flexible joint generally adopts the double-layer combination method of "compression rubber waterstop (GINA) + external pasted rubber waterstop (OMEGA)". The GINA waterstop is installed at the joint of the tube section, and the OMEGA waterstop is arranged on the outer wall of the tube section. The OMEGA waterstop is the direct component that bears the influence of environmental deformation on the connection of the tube sections.

[0003] When the existing OMEGA waterstop is in use, the following disadvantages exist:

[0004] First, the construction process of the existing OMEGA waterstop is complex. The embedded sleeves and angle steels need to be welded together with the steel bars. Therefore, before the subsequent installation of the waterstop, holes need to be drilled at the corresponding positions of the formwork, which affects the secondary utilization of the formwork and the construction period allocation. Moreover, when installing the OMEGA waterstop, it needs to be paved in a relay transmission manner by multiple people so that the installation position of the waterstop corresponds to the joint of the segment. Since each circle of the waterstop is long and heavy, it is inconvenient to install. Especially when installing the waterstop on the top plate and side wall of the tube section, multiple people need to support the waterstop to make it close to the embedded parts, and then the waterstop is fixed on the embedded parts through the pressing plates at each fixed position. At the same time, whether it is the lever-type and perforated-type pressing parts, after the unilateral pressing part is fixed, affected by errors, the alignment installation on the other side with the perforation is more difficult, greatly increasing the construction difficulty. Since the installation of the waterstop is an underwater operation, most of the installation process of this type of waterstop requires manual labor. Therefore, the underwater operation results in a significant increase in labor intensity, high difficulty, and long construction time.

[0005] Second, when the water flow in the tube section is very large, the water pressure in the tube section will increase accordingly, and the water pressure received by the OMEGA waterstop is also relatively large. The OMEGA waterstop is made of rubber material. When the OMEGA waterstop is in a tight state for a long time, it is easy to cause permanent deformation of the OMEGA waterstop, resulting in a decline in the sealing and waterproof effect of the OMEGA waterstop.

[0006] Therefore, we propose a new type of OMEGA pressing structure that is convenient for installation to solve the above problems. Summary of the Invention

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] As Figure 1-6 shown, a new type of OMEGA pressing part structure that is convenient for installation includes two embedded angle steels 1, and the two embedded angle steels 1 are respectively fixed at the interfaces of two precast pipe sections 2. The upper side walls of the two embedded angle steels 1 are provided with the same OMEGA water stop belt body 3. The upper side of the OMEGA water stop belt body 3 is covered with a plurality of Ω pressing plates 4. The right side of the OMEGA water stop belt body 3 and the Ω pressing plates 4 are inserted with the same right stud 5, and the lower end of the right stud 5 is located inside the chemical anchor bolt 6 embedded in the precast pipe section 2. A right fixed anchor bolt 7 is fixedly sleeved outside the right stud 5. An extension plate is provided on the lower side of the right fixed anchor bolt 7. A left stud 8 is inserted into the left embedded angle steel 1. The lower end of the left stud 8 is located inside the chemical anchor bolt 6 embedded in the precast pipe section 2. A left fixed anchor bolt 9 is fixedly sleeved outside the left stud 8. A pressing block 10 is sleeved outside the left stud 8. A round steel 11 is provided below the pressing block 10. A protrusion 12 is provided on the left side of the Ω pressing plate 4. A groove 13 matching the protrusion 12 is opened on the lower side wall of the pressing block 10.

[0029] The upper side walls of two embedded angle steels 1 are both fixedly connected with the same sealing cover 14 through bolts. An air pump 15 is fixedly connected to the upper side wall of the sealing cover 14. The air outlet end of the air pump 15 is fixedly communicated with an exhaust pipe 16. An intake pipe 17 is fixedly communicated with the pipe wall of the exhaust pipe 16. An air outlet pipe 18 is fixedly communicated with the left side wall of the sealing cover 14. The lower end of the intake pipe 17 and the left end of the air outlet pipe 18 are both communicated with an adjusting mechanism 19. An induction cylinder 26 is fixedly connected to the inner wall of the precast pipe section 2. A ventilation pipe 27 is communicated with the rear side wall of the induction cylinder 26. The rear end of the ventilation pipe 27 extends out of the precast pipe section 2. The induction cylinder 26 is located in the middle part of the precast pipe section 2. An air bag 28 is fixedly communicated with the side wall of the induction cylinder 26. A piston plate 29 and a marking plate 30 are slidably connected in the induction cylinder 26. Electrically conductive plates 31 are fixedly connected to both the upper and lower side walls of the marking plate 30. A lower conductive block 32 is fixedly connected to the upper side wall of the piston plate 29. A bent plate 33 is fixedly connected to the upper side wall of the piston plate 29. Communicating components 34 are fixedly connected to both the upper side walls of the piston plate 29 and the bent plate 33. The upper end of the bent plate 33 passes through the marking plate 30, and an upper conductive block 39 is fixedly connected to the inner wall. Resistor plates 40 that match the communicating components 34 are fixedly connected to both the left and right sides of the induction cylinder 26. The upper end of the resistor plate 40 on the right side is electrically connected to the adjusting mechanism 19 on the right side, and the lower end of the resistor plate 40 on the left side is electrically connected to the adjusting mechanism 19 on the left side. The electrically conductive plates 31 are electrically connected to an external power source. The upper conductive block 39 is connected to the upper communicating component 34 through a timing controller, and the lower conductive block 32 is electrically connected to the air pump 15 through a time relay. After the OMEGA waterstop belt is subjected to a strong water pressure, a certain air pressure can be applied to the other side of the OMEGA waterstop belt to balance the water pressure borne by the OMEGA waterstop belt, avoiding the OMEGA waterstop belt being in a tight state for a long time, resulting in permanent deformation of the OMEGA waterstop belt and causing the problem of the sealing and waterproof effect of the OMEGA waterstop belt decreasing.

[0030] An electric push rod 41 is fixedly connected to the inner wall of the upper side of the sealing cover 14. The electric push rod 41 is electrically connected to an external power supply through a timing controller. The output end of the electric push rod 41 is fixedly connected to a cylinder 42. The inner wall of the cylinder 42 is fixedly connected to a lifting plate 43 through a spring. A top block 44 is fixedly connected to the lower side wall of the lifting plate 43. The lower end of the top block 44 extends out of the cylinder 42. Metal plates 45 are fixedly connected to the side walls of the opposite sides of the lifting plate 43 and the cylinder 42. The metal plate 45 on the lower side is electrically connected to an external power supply. A bent pipe 46 is fixedly communicated with the upper side wall of the sealing cover 14. A piston block 47 is inserted into the bent pipe 46. A motor 48 is fixedly connected to the upper side wall of the sealing cover 14. The output end of the motor 48 is fixedly connected to a circular plate 49. The circular plate 49 and the piston block 47 are hinged by the same connecting rod 50. The upper metal plate 45 is electrically connected to the motor 48 through a time relay. By setting the timing controller, the electric push rod 41 reciprocates every two weeks. The electric push rod 41 drives the cylinder 42 to move in the direction where the OMEGA water stop belt body 3 is exposed outside the Ω pressing plate 4, so that the top block 44 contacts the OMEGA water stop belt body 3. When there is more scale attached to the inner side of the OMEGA water stop belt body 3, the OMEGA water stop belt body 3 will become hard, its elasticity will also weaken, and the supporting force of the OMEGA water stop belt body 3 will also increase accordingly. After the top block 44 contacts the OMEGA water stop belt body 3, the pushing force between the OMEGA water stop belt body 3 and the top block 44 will overcome the elastic force of the spring and push the lower metal plate 45 upward to contact the upper metal plate 45, thereby connecting the circuit of the motor 48 through the time relay. By setting the time relay, the motor 48 works continuously for one minute. The motor 48 will drive the circular plate 49 to rotate. The circular plate 49 controls the piston block 47 to reciprocate in the bent pipe 46 through the connecting rod 50, so that the air pressure in the sealing cover 14 drops and rises suddenly. The OMEGA water stop belt body 3 will shake continuously under the change of air pressure, so that the scale attached to the OMEGA water stop belt body 3 will fall off, avoiding that too much scale on the OMEGA water stop belt surface will affect the shrinkage and sealing effect stability of the OMEGA water stop belt.

[0031] The adjusting mechanism 19 includes two fixed boxes 191 and a placement plate 192. The two fixed boxes 191 are respectively communicated with the ends of the intake pipe 17 and the outlet pipe 18. The placement plate 192 is located on the inner wall of the fixed box 191. A vertical rod 20 is inserted into the side wall of the placement plate 192. The lower end of the vertical rod 20 is fixedly connected with a connecting plate 21. The same spring is fixedly connected between the connecting plate 21 and the placement plate 192. One end of the vertical rod 20 far from the connecting plate 21 is fixedly connected with a tapered plug 22. A permanent magnet plate 23 is fixedly connected to the lower side wall of the connecting plate 21. A support frame 24 is fixedly connected to the inner wall of the fixed box 191. An electromagnet 25 is fixedly connected to the upper side wall of the support frame 24. The electromagnet 25 on the right is electrically connected to the right resistor plate 40, and the electromagnet 25 on the left is electrically connected to the left resistor plate 40, which is convenient for adjusting the air volume of the intake pipe 17 and the outlet pipe 18.

[0032] The connecting component 34 includes two support seats 341 and a fixed frame 342. The two support seats 341 are arranged in opposite directions. The fixed frame 342 is fixedly connected with the support seats 341. A metal wheel 35 is fixedly connected to the inner wall of the fixed frame 342. An insulating pad 36 is fixedly sleeved on the outside of the metal wheel 35. A limiting plate 37 is fixedly connected to the inner wall of the fixed frame 342. Two blocking blocks 38 are fixedly connected to the outer wall of the metal wheel 35. The upper metal wheel 35 and the upper conductive block 39 are electrically connected through a time relay. The lower metal wheel 35 and the external power supply are electrically connected. When the piston plate 29 moves upward, the metal wheel 35 on the right will contact the resistor plate 40 on the right, and the metal wheel 35 on the left will not contact the resistor plate 40 on the left. When the piston plate 29 moves downward, the metal wheel 35 on the left will contact the resistor plate 40 on the left, and the metal wheel 35 on the right will not contact the resistor plate 40 on the right.

[0033] An exhaust port 51 is opened on the side wall of the fixed box 191. A baffle 52 located outside the exhaust port 51 is hinged on the side wall of the fixed box 191. The same spring is fixedly connected between the baffle 52 and the fixed box 191, which can discharge the gas from the fixed box 191 and prevent external gas from entering the fixed box 191.

[0034] A guiding cylinder sleeved outside the airbag 28 is fixedly connected to the outer wall of the induction cylinder 26. A water blocking plate 53 is fixedly connected to the end of the airbag 28, which can protect the airbag 28.

[0035] A protective cover 54 covering the motor 48 is fixedly connected to the upper side wall of the sealing cover 14. A waterproof pad 55 is fixedly connected to the lower side wall of the sealing cover 14, which can protect the motor 48 and ensure the sealing performance of the sealing cover 14.

[0036] The operating principle of the present invention is described as follows: The embedded angle steel 1 is welded and fixed on the precast pipe section 2 after the steel bar project stage. The right stud 5 is inserted into the chemical anchor bolt 6 through the OMEGA waterstop body 3 and the Ω pressing plate 4, and the upper end is fastened by the right fixing anchor bolt 7. Then, the left stud 8 is inserted into the chemical anchor bolt 6 through the pressing block 10 and fixed, and the upper end is fastened by the left fixing anchor bolt 9. The left fixing anchor bolt 9 is in direct contact with the pressing block 10. One end of the pressing plate presses on the round steel 11 and the other end presses on the Ω pressing plate 4. This method avoids the influence of the installation error of the unilateral pressing part on the installation of the other side. At the same time, the new type of anchor bolt is convenient to install and has higher strength. Moreover, this device can effectively reduce the difficulty of underwater installation, shorten the operation time, reduce risks, and provide higher local strength and durability. After anti-corrosion treatment, the service life of the entire OMEGA waterstop and related components is effectively extended. After the OMEGA waterstop is pulled to the initial waterstop stage, it has been proved by practice that it can effectively ensure the waterstop effect and quickly drain the water at the joint. In addition, the waterstop structure has a wide applicability and does not affect the original high water pressure resistance and the ability to adapt to structural deformation, and has good application prospects;

[0037] When the water pressure inside the precast pipe section 2 is relatively high, the airbag 28 will be squeezed by the water, so that the air in the airbag 28 is transported into the induction cylinder 26. The gas will push the piston plate 29 to move upward. The piston plate 29 drives the lower conductive block 32 to contact the lower power-on plate 31, thereby connecting the air pump 15 to work. And the operation of the air pump 15 is controlled by the set time relay for a certain period of time. The piston plate 29 will push the marking plate 30 to move upward. During the upward movement of the piston plate 29, the metal wheel 35 on the right will contact the resistor plate 40 on the right. When the metal wheel 35 contacts the resistor plate 40 on the right, the circuit of the electromagnetic block 25 on the right will be connected, so that the electromagnetic block 25 on the right contacts. When the metal wheel 35 gradually moves upward, the resistance of contacting the electromagnetic block 25 will gradually decrease, and the magnetism of the electromagnetic block 25 will gradually increase, so that the magnetic force of the electromagnetic block 25 attracting the permanent magnet plate 23 will gradually increase, thereby attracting the connecting plate 21, the vertical rod 20 and the conical plug 22 to gradually move downward, thereby changing the size of the outlet of the air inlet pipe 17, so that a part of the gas is discharged from the exhaust pipe 16, and a part of the gas enters the fixed box 191 through the air inlet pipe 17 and is transported to the sealing cover 14 through the exhaust port 51, so that the pressure inside the sealing cover 14 increases, which is used to counteract the water pressure received inside the OMEGA waterstop body 3. When the water pressure is stronger, more gas enters the sealing cover 14, and the pressure inside the sealing cover 14 is also higher, so as to ensure that the pressures on the upper and lower sides of the OMEGA waterstop body 3 are kept as equal as possible, avoiding the OMEGA waterstop being in a tight state for a long time, resulting in permanent deformation of the OMEGA waterstop and causing the problem of the sealing and waterproof effect of the OMEGA waterstop decreasing. When the water pressure inside the precast pipe section 2 drops, the airbag 28 will gradually return to its original state. When the airbag 28 returns to its original state, the air pressure below the piston plate 29 will decrease, and the piston plate 29 will gradually move downward. The piston plate 29 drives the marking plate 30 to move downward through the bent plate 33. When the bent plate 33 drives the marking plate 30 to move downward, the lower conductive block 32 is separated from the lower power-on plate 31, disconnecting the circuit of the air pump 15. The upper conductive block 39 will contact the upper power-on plate 31, thereby connecting the circuit of the left metal wheel 35. The left metal wheel 35 contacts the resistor plate 40 on the left. When the metal wheel 35 moves downward, the left metal wheel 35 will rotate a certain angle through the mutual cooperation of the limiting plate 37 and the blocking block 38, so that the metal part of the metal wheel 35 contacts the resistor plate 40 on the left, and the circuit of the left electromagnetic block 25 can be connected, so that the excess gas in the sealing cover 14 is discharged. Similarly, when the two metal wheels 35 move downward, the metal wheel 35 on the right will also rotate, so that the insulating pad 36 contacts the resistor plate 40 on the right, thereby disconnecting the circuit of the electromagnetic block 25 on the right. The metal wheel 35 on the left can control the operation of the solenoid valve at the left end for a short time through the timing controller, so as to avoid discharging all the gas in the sealing cover 14 at one time.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
