Description

Technical Field

[0002] Bridges are an important part of transportation infrastructure; whether they are cross-sea or cross-river bridges, or urban viaducts, they all carry the transportation functions of roads or railways; the bridge pile foundation is the key structure of the lower part of the bridge, and plays a key supporting role for the bridge; whether the pile foundation is stable plays a decisive role in the service life and safety of the bridge.

[0003] Pile foundation protection is not only about protecting against structural problems such as cracking of the pile foundation itself, but also about protecting against damage that may be caused to the pile foundation by external factors, such as vehicle collisions that may occur to the pile foundation of urban viaducts; and ship collisions that may occur to cross-river or cross-sea bridges. Therefore, the prior art discloses a protective device for bridge anti-collision, which is arranged at the pile foundation of the bridge to reduce the damage that may be caused to the bridge by external impact forces. However, for the pile foundation of a bridge that crosses a river, in addition to anti-collision protection, the impact force of river torrents on the pile foundation is also a key factor causing safety hazards to the pile foundation of the bridge. The current pile foundation protection device directly sets drainage holes on it, but the setting of the drainage holes, on the one hand, weakens the anti-collision effect of the protection device, and on the other hand, the drainage holes only play the role of guiding the torrent, but the impact force of the torrent still does not avoid the pile foundation and can still act on the pile foundation.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] Example 1

[0044] A bridge pile foundation protection device, comprising: a pile foundation protection clamping plate 1, a buffer protection plate 2, a guide plate 3, a guide plate driving structure, an anti-collision buffer component, and an anti-collision buffer balance component;

[0045] The protective pile foundation clamping plate 1 is used to cover the outer side of the pile foundation and is detachably connected to the pile foundation; the specific disassembly structure is: the protective pile foundation clamping plate 1 is set to include two mirror-symmetrical clamping plates, and after the two clamping plates are closed, the outer periphery of the pile foundation can be completely covered;

[0046] Each of the two sides of the clamping plate is provided with an attachment ear 101. In this embodiment, three attachment ears 101 are provided on one side. The number of the attachment ears 101 is adaptively set according to the height of the protective pile foundation clamping plate 1. When the two clamping plates are closed, the attachment ears 101 thereon can correspond one to one. Figure 3 As shown, the structure of the pile foundation protection clamping plate 1 is formed after the clamping plates are closed, and the six pairs of attachment ears 101 in the upper, middle and lower parts can correspond to each other one by one; bolt holes are arranged on the attachment ears 101, and fastening bolts 102 are arranged in the bolt holes; after the clamping plates are covered on the pile foundation, the fastening bolts fasten the two clamping plates, and at the same time, the entire pile foundation protection clamping plate 1 is fixed to the outer surface of the pile foundation;

[0047] like Figure 3 As shown, in this embodiment, the protective pile foundation clamp is set as a cylindrical pile; in actual application, the shape and structure of the fixing plate can be designed according to the structural shape of the pile foundation; for example, if the pile foundation is a rectangular column, the two fixing plates can be designed to be a rectangular column when closed.

[0048] like Figure 1 As shown in or 2, a buffer protection plate 2 is arranged in a circumferential distribution on the outer side of the protective pile foundation clamp plate 1; an anti-collision buffer component is arranged between the buffer protection plate 2 and the protective pile foundation clamp plate 1, and the best setting position is the midline of the buffer protection plate 2 and the protective pile foundation clamp plate 1; when a foreign object collides with the pile foundation, the impact force first acts on the buffer protection plate 2, and then the impact force is changed in direction and buffered and absorbed by the anti-collision buffer component, thereby minimizing the impact of the force on the pile foundation;

[0049] like Figure 3 and Figure 6 As shown, the above-mentioned anti-collision buffer assembly includes: a buffer vertical rod 6, a slide rod 601, an elastic member 602, a sliding ring 606, a hinge plate 607, and a buffer arm 603; a slide rod 601 is vertically arranged in the buffer vertical rod 6;

[0050] Two sliding rings 606 are movably mounted on the slide bar 601; elastic members 602 are arranged between the upper sliding ring 606 and the upper end of the buffer vertical rod 6 and between the lower sliding ring 606 and the lower end of the buffer vertical rod 6, and the elastic members 602 in this embodiment are springs; the springs are mounted on the outer periphery of the slide bar 601 and have no contact with the slide bar 601; hinged plates 607 are arranged on the sliding ring 606, and the tail ends of a buffer arm 603 are hinged in the upper and lower hinged plates 607, and the head ends of the two buffer arms 603 are connected by a hinge joint 604; a fixed block 605 is arranged on the hinge joint 604, and the fixed block 605 is welded to the inner wall of the buffer protection plate 2.

[0051] When a collision occurs, the impact force directly acts on the buffer protection plate 2, and then the buffer protection plate 2 moves inward under the action of the force. During the inward movement, the anti-collision buffer component plays a role, and the two buffer arms 603 move in the upward and downward directions respectively, pushing the sliding ring 606 to move on the sliding rod 601, compressing the spring, and the spring plays a buffering role; at this time, the impact force is actually dispersed to the upper and lower directions, coupled with the buffering absorption effect, the impact force directly acting on the pile foundation is very small.

[0052] Ideally, the center of the impact is exactly at the center line of the buffer protection plate. However, if the impact point deviates from the center line, the buffer protection plate 2 will be excessively tilted to one side. In addition, the impact force is generated suddenly and increases sharply, and the buffer protection plate 2 is likely to be separated from the fixed block 605, causing the buffer protection plate 2 to detach from the anti-collision buffer component. Considering the offset of the impact point, the buffer protection plate 2 needs to be balanced. Therefore, anti-collision buffer balancing components are arranged around the anti-collision buffer component. When the impact deviates from the center line, the anti-collision buffer balancing component can play an auxiliary buffering role to prevent the buffer protection plate 2 from tilting rapidly to one side after the force increases sharply. Figure 3As shown, the anti-collision buffer balance assembly includes four buffer damping columns 4, and the telescopic section of the buffer damping column 4 is covered with an elastic member, which is a spring, and the two ends of the spring are respectively arranged on the surface of the protective pile foundation clamp 1 and the buffer damping column base section 401; Figure 3 The buffer damping columns 4 are respectively located at the vertices around the anti-collision buffer component, and the projections of the four vertices connected are rectangular.

[0053] The guide plate 3 is movably arranged on the buffer protection plate 2, one side of the guide plate 3 is arranged on the side wall of the buffer protection plate 2 through a hinged joint shaft rod 301, and the other side is separated from the buffer protection plate 2; Figure 1 or Figure 2 As shown, the guide plates 3 are arranged in groups in front and behind according to the flow direction of the water flow, and a group of guide plates 3 includes two guide plates 3 arranged in mirror symmetry on the left and right; under the action of the guide plate driving structure, the guide plates 3 are unfolded, and the two opposite sides of the two guide plates 3 in one group are close together, and the two guide plates 3 form a conical cylindrical structure. When the flood hits the conical cylindrical guide plate 3, it can automatically be divided into two sides, guiding and diverting the flood and bypassing the pile foundation. A guide groove 302 is arranged on the outer surface of the guide plate 3, and the guide groove 302 can be used to accelerate the guiding and diverting effect of the flood.

[0054] The above-mentioned guide plate driving structure can directly replace the hinged hinge shaft rod 301 with an electrically controlled rotating shaft rod, and directly use the hinged joint with the buffer protection plate 2 as the electrically controlled driving structure of the guide plate 3; the electrically controlled rotating shaft rod is used to drive the guide plate 3 to unfold;

[0055] like Figure 2 As shown in Figure 4, in this embodiment, the guide plate driving structure is arranged above the buffer protection plate 2 and the guide plate 3;

[0056] The guide plate driving structure includes: a rotating shaft seat 501, a hydraulic push rod 5, an embedded rod 502, and a guide slide groove 304;

[0057] The shaft seat 501 is arranged above the buffer protection plate 2, and the tail end of the hydraulic push rod 5 is arranged on the shaft seat 501, and the hydraulic push rod 5 can rotate around the shaft seat 501; the guide slot 304 is arranged above the guide plate 3; an embedding rod 502 is arranged below the telescopic end of the hydraulic push rod 5, and the embedding rod 502 is movably embedded in the guide slot 304; the hydraulic push rod 5 extends to give an external thrust to the guide plate 3, and at the same time cooperates with the shaft seat 501 and the free movement of the embedding rod 502 in the guide slot 304, so that the guide plate 3 can be pushed away from the buffer protection plate 2 to make it unfold. Figure 2 As shown, when the two guide plates 3 of the same group are unfolded, a raised conical structure can be formed when viewed from a top view. This conical cylindrical structure can be used to forcibly guide the flood. When the flood encounters the conical cylindrical structure, it will be diverted to both sides by itself, destroying its impact force and allowing the flood to avoid the pile foundation.

[0058] Example 2

[0059] Based on the embodiment 1, two guide plates 3 of the same group are unfolded to form a conical cylinder; if the length of the two guide plates 3 is not enough, the two opposite sides may not touch each other, and a gap will be formed in the middle; the torrent will enter from the gap and eventually act on the buffer protection plate 2, causing the buffer protection plate 2 to bear pressure, such as Figure 1 , and part of the flood will also directly act on the protective pile foundation clamping plate 1 from the gap between the two buffer protection plates 2;

[0060] So, if Figure 2 As shown, this embodiment is based on the guide plate 3 in embodiment 1. On the side where the guide plate 3 is separated from the buffer protection plate 2, an interlayer is provided inside the guide plate 3, and an extension plate 303 is movably provided inside the interlayer; the depth of the interlayer is determined according to the length of the arc surface of the extension plate 303; the upper and lower side surfaces of the guide plate interlayer are connected to the upper and lower side surfaces of the extension plate by an extended sliding structure.

[0061] The extended sliding structure in this embodiment comprises: sliding convex strips arranged on the upper and lower sides of the guide plate interlayer, and sliding grooves arranged on the upper and lower sides of the extension plate; when the extension plate 303 is arranged in the interlayer, the convex strips are located in the grooves; the extension plate 303 can slide in the interlayer by the cooperation and guidance of the convex strips and the grooves to achieve extension or recovery;

[0062] The above-mentioned extension sliding structure is a manual structure, and it is necessary to manually drag the extension plate 303 out of the interlayer after the guide plates 3 are unfolded, so as to achieve the purpose of extending the length of the guide plates 3 and fill the gaps between the guide plates 3.

[0063] Example 3

[0064] Based on Example 2, on the side where the guide plate 3 is separated from the buffer protection plate 2, a interlayer is set inside the guide plate 3, and an extension plate 303 is movably set inside the interlayer; the depth of the interlayer is determined according to the arc length of the extension plate 303; the upper and lower side surfaces of the guide plate interlayer are connected to the upper and lower side surfaces of the extension plate through an extended sliding structure.

[0065] The extended sliding structure of Example 3 is: an electrically controlled slide rail arranged on the upper and lower sides of the guide plate interlayer and an electrically controlled slider arranged on the upper and lower sides of the extension plate; the electrically controlled slider is movably embedded in the electrically controlled slide rail, and under the action of the electrically controlled slide rail and the electrically controlled slider, the extension plate 303 can be pushed out or retracted from the interlayer.

[0066] The driving structure and principle of the electric-controlled slide rail and the electric-controlled slider are existing technologies and will not be repeated here; the cooperation between the electric-controlled slide rail and the electric-controlled slider enables the extension or retraction of the extension plate 303 to be automatically controlled without manual operation; when a flood comes, it can be deployed together with the guide plate 3; the response is more timely.

[0067] Example 4

[0068] Based on the second or third embodiment, two guide plates 3 of the same group are unfolded, and two extension plates 303 extend out of the guide plate interlayer until two opposite sides of the extension plates 303 are in contact; the guide structure of the guide plate 3 is completed; however, there is no connection structure between the two extension plates 303, especially for the manually driven extension plates 303 in the second embodiment, it is very likely that the extension plates 303 will be washed back into the interlayer under the flood, and a gap will be generated again;

[0069] like Figure 2 and Figure 5 As shown, a hook shaft 305 is provided on one side of the extension plate 303 outside the interlayer, and a fixing hook 306 is movably provided on the hook shaft 305; a fixing ring 307 is correspondingly provided on the extension plate 303 on the opposite side; the fixing hook 306 is hooked in the fixing ring 307 to connect the opposite sides of the extension plates 303 of the same group; so that the two extension plates 303 are restrained from each other to prevent them from retracting into the interlayer.

[0070] Example 5

[0071] Based on embodiments 1, 2, and 4, a water flow monitor 7 is provided on the protective pile foundation clamp 1, and the water flow monitor 7 is communicatively connected to the hydraulic push rod 5 and the electric control slide rail and slider driving central control of the extension plate; whether the guide plate 3 needs to be deployed is determined by the water flow monitoring result.

[0072] When the water flow monitor 7 detects a sudden increase in water flow and there is a danger of a flood, the monitoring information is fed into the drive control, which issues instructions to the corresponding hydraulic push rod 5 and the electric control slide rail and slider to immediately deploy the guide plate 3 and the extension plate 303.
