Further, the force storage column is in friction contact with the fixing frame, and when the force storage column extrudes the elastic piece to enable the force storage of the elastic piece to be larger than a preset value, the force storage column overcomes the friction force between the force storage column and the fixing frame to move.
Further, the belt pressing mechanism further comprises an adjusting component, and when the water-based polyurethane absorbs water again to expand after losing water and moves to a first preset position in the direction close to the force storage column through the pressing column and the hydraulic oil pushing sealing column, the adjusting component promotes the force storage column to move to a second preset position in the direction close to the sealing column.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of the present invention, a large span monolithic basement deformation joint seepage prevention structure, is disposed at the deformation joint between two substrates 100, as shown in fig. 1 to 6, and comprises a water blocking belt 300 and two belt pressing mechanisms 400.
The water blocking tape 300 is disposed between two substrates 100 distributed along the first direction, and two tape pressing mechanisms 400 fix both sides of the water blocking tape 300 in the first direction to the two substrates 100, respectively.
The water blocking tape 300 is filled with the aqueous polyurethane 500 between the side close to the substrate 100 and the substrate 100 in the second direction, and the aqueous polyurethane 500 swells after absorbing water and shrinks after losing water. The second direction is a direction perpendicular to the plane of the two substrates 100.
The belt press 400 includes a mount 410, a press post 420, a seal post 430, a power storage post 440 and an elastic member 450,
The fixing frame 410 is fixedly installed on the base body 100, a hydraulic cavity is arranged in the fixing frame 410, and hydraulic oil is filled in the hydraulic cavity; the pressing columns 420 are arranged in sequence along the first direction and are slidably arranged on the fixing frame 410 along the second direction; one end of the pressing column 420 is used for abutting against one side, far away from the aqueous polyurethane 500, of the water barrier 300, and the other end of the pressing column is positioned in the hydraulic cavity; the effective displacement of the plurality of pressing columns 420 moving along the second direction towards the direction approaching the water-blocking tape 300 increases sequentially along the first direction and towards the direction approaching the deformation joint, and the fixing frame 410 limits the continuous movement of the pressing columns 420 after moving corresponding effective displacement towards the direction approaching the water-blocking tape 300. The force storage column 440 is mounted on the fixing frame 410, the sealing column 430 is slidably mounted in the hydraulic cavity and is connected with the force storage column 440 through the elastic member 450, and the elastic member 450 causes the sealing column 430 to move to squeeze hydraulic oil in the hydraulic cavity, so as to cause the pressing column 420 to move towards the direction approaching the water blocking belt 300. Wherein the elastic member 450 is a spring.
The water-based polyurethane 500 seals between the water-blocking tape 300 and the substrate 100 through water absorption expansion, after the water-based polyurethane 500 is dehydrated and contracted due to environmental drying, the sealing column 430 moves and extrudes hydraulic oil in the hydraulic cavity under the action of the elastic piece 450, so that the pressing column 420 moves towards the direction close to the water-blocking tape 300 and extrudes the water-blocking tape 300, and the water-blocking tape 300 and the water-based polyurethane 500 keep sealed. Along with the movement of the sealing post 430, the storage force of the elastic member 450 is gradually reduced, and the top pressure applied to the pressing post 420 is also gradually reduced, so that the pressing force of hydraulic oil is not further divided after the corresponding effective displacement of the pressing post 420 is moved, so that the pressing posts 420 which are not moved to the corresponding effective displacement bear the top pressure, and further, the top pressure of at least one pressing post 420 on the water-blocking belt 300 is ensured to be basically unchanged compared with the top pressure of the pressing post 420 on the water-absorbing polyurethane 500 in the water-absorbing expansion state. The effective displacement of the plurality of pressing columns 420 moving along the second direction towards the direction close to the water-blocking tape 300 increases sequentially along the first direction and towards the direction close to the deformation joint, so that the pressing force of the pressing column 420 closest to the deformation joint to the water-blocking tape 300 can be kept substantially unchanged compared with the pressing force of the pressing column 420 to the water-soluble polyurethane 500 in the water-absorbing expansion state. Specifically, there are N pressure columns 420, and in the initial state, the elastic force F of the elastic member 450 acts on each pressure column 420 through the sealing column 430 and the hydraulic oil with a pressing force F/N; the movement of the press stud 420 and the damping of the elastic force F of the elastic member 450 may be calculated and configured such that the following relationship is satisfied: when the elastic force of the elastic member 450 is reduced by F/N, one pressing column 420 moves to a position limited by the fixing frame 410, the elastic force of the elastic member 450 is reduced to F/N, and the pressing column 420 closest to the deformation joint bears all the pressing force of the elastic member 450, so that the pressing force of the pressing column 420 to the water-proof belt 300 is as consistent as possible under the water absorption and water loss state of the water-proof polyurethane 500, the expansion of the elastic member 450 is not reduced, and the sealing effect between the water-proof belt 300 and the matrix 100 is ensured.
In the present embodiment, the force storage column 440 is in frictional contact with the fixing frame 410, and when the force storage column 440 presses the elastic member 450 to make the force storage force greater than a predetermined value, the force storage column 440 moves against the frictional force with the fixing frame 410. By making the force storage column 440 in frictional contact with the fixing frame 410, the force storage of the elastic member 450 does not exceed a preset value, so that the acting force of the elastic member 450 on the water-blocking tape 300 through the sealing column 430, the hydraulic oil and the pressure column 420 is as stable as possible.
In this embodiment, the belt pressing mechanism 400 further includes an adjusting component 460, and when the aqueous polyurethane 500 absorbs water again to expand after losing water and moves to a first preset position in a direction approaching the force storage column 440 through the pressing column 420 and the hydraulic oil pushing the sealing column 430, the adjusting component 460 urges the force storage column 440 to move to a second preset position in a direction approaching the sealing column 430, and the second preset position is closer to the sealing column 430 than the initial position of the force storage column 440. When the aqueous polyurethane 500 expands again after each water loss, the expansion degree is attenuated compared with the expansion degree of the previous time, and by moving the force storage column 440 towards the direction close to the force storage column 440 each time when the sealing column 430 moves towards the direction close to the force storage column 430, the displacement reduction of the sealing column 430 caused by the attenuation of the expansion degree of the aqueous polyurethane 500 is compensated, the elastic piece 450 can be compressed and stored to a preset value each time when the sealing column 430 moves towards the direction close to the force storage column 440, and after the elastic piece 450 is compressed and stored to the preset value by the sealing column 430, the force storage column 440 is pushed to move towards the direction far away from the sealing column 430 until the expansion of the aqueous polyurethane 500 is completed.

In this embodiment, a large-span connected basement deformation joint seepage-proofing structure further includes a shroud plate 200, the shroud plate 200 is installed between two substrates 100 and two belt pressing mechanisms 400 are far away from one side of the water-blocking belt 300, the shroud plate 200 covers the deformation joint to prevent the water-blocking belt 300 and the belt pressing mechanisms 400 from being damaged.
The large-span connected basement deformation joint seepage-proofing structure can be used for deformation joints of two matrixes 100 on the ground and can also be used for deformation joints between two matrixes 100 on a wall. When in use, the water-proof belt 300 is covered on the deformation joint, two sides along the first direction are respectively supported by the two matrixes 100, the fixing frames 410 of the two belt pressing mechanisms 400 are respectively fixed on the two matrixes 100 through the bolts 411 and the nuts 412, the water-proof belt 300 and the matrixes 100 are filled with the water-based polyurethane 500, the water-based polyurethane 500 is in a water absorption state in an initial state, and the plurality of pressing columns 420 of the belt pressing mechanisms 400 press the water-proof belt 300 under the action of the elastic pieces 450, so that the water-proof belt 300 and the matrixes 100 are sealed through the water-based polyurethane 500.
When the water-based polyurethane 500 is dehydrated and contracted along with the drying of the weather, the elastic piece 450 moves to the direction close to the water-blocking tape 300 through the sealing column 430 and the hydraulic oil pushing pressure column 420, so that the water-blocking tape 300 and the water-based polyurethane 500 are kept in fit and seal. And along with the further shrinkage of the aqueous polyurethane 500, the sealing column 430 continuously moves towards the direction far away from the force storage column 440 under the action of the elastic element 450, so that the plurality of pressing columns 420 from the direction far away from the deformation joint to the direction close to the deformation joint sequentially move to be in butt joint with the end part of the mounting hole, part of the pressing columns 420 do not move after moving to be in butt joint with the end part of the mounting hole, the extrusion force of hydraulic oil is not divided, so that other pressing columns 420 which do not move to be in butt joint with the end part of the mounting hole bear the jacking force, and the jacking force of at least one pressing column 420 on the water-blocking belt 300 is ensured to be kept basically unchanged. And the effective displacement of the plurality of pressing columns 420 moving along the second direction towards the direction close to the water-blocking tape 300 sequentially increases along the first direction and towards the direction close to the deformation joint, so that the pressing force of the pressing column 420 closest to the deformation joint to the water-blocking tape 300 can be kept basically unchanged. When the sealing post 430 moves away from the force storage post 440, the limiting plate 461 is driven to move away from the force storage plate 462 until the limiting plate 461 moves to be abutted against the end of the chute and then no longer moves along with the sealing post 430, and the limiting plate 461 is always abutted against the limiting post 465 in the process that the limiting plate 461 moves away from the force storage plate 462, so that the force storage plate 462 is prevented from rotating.
When the water-based polyurethane 500 absorbs water again and expands, the water-based polyurethane 500 pushes the pressing column 420 to move away from the water-blocking tape 300 through the water-blocking tape 300, the pressing column 420 pushes the sealing column 430 to move towards the direction close to the force-accumulating column 440 through extruding hydraulic oil, the sealing column 430 drives the limiting plate 461 to move synchronously until the limiting plate 461 moves to a first preset position along with the sealing column 430, the limiting column 465 is separated from the limiting plate 461, the force-accumulating disc 462 rotates by a preset angle under the action of the force-accumulating part 464 and is blocked by the limiting plate 461 again, and the force-accumulating disc 462 drives the eccentric wheel 463 to rotate by a preset angle, so that the eccentric wheel 463 pushes the force-accumulating column 440 to move towards the direction close to the sealing column 430 to a second preset position. Then, the sealing post 430 continues to move towards the direction close to the force storage post 440 under the expansion action of the aqueous polyurethane 500, the elastic piece 450 is pressed to store the force to a preset value, and then the force storage post 440 is pushed to move synchronously, so that the jacking force of the pressing post 420 on the water-blocking tape 300 is kept as stable as possible. Until the aqueous polyurethane 500 is dehydrated and contracted again, the plurality of pressing columns 420 press the water-blocking tape 300 under the action of the elastic member 450.
When the water-based polyurethane 500 absorbs water and expands again after water loss each time, the force storage column 440 moves to a second preset position in the direction close to the sealing column 430 so as to compensate for the displacement reduction of the sealing column 430 caused by the attenuation of the expansion degree of the water-based polyurethane 500 or the reduction of the thickness of the water-blocking tape 300, so that the elastic piece 450 can be compressed and stored to a preset value when the sealing column 430 moves in the direction close to the force storage column 440 each time, and the stability of the pressing force of the pressing column 420 to the water-blocking tape 300 is further ensured.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
