Description

Technical Field

[0001] The utility model belongs to the technical field of bridge crack repair, and specifically relates to a bridge crack repair device using microorganisms. Background Art

[0002] Microbial induced calcium carbonate precipitation (MICP) technology is a technology that uses calcium carbonate precipitation produced by microorganisms during metabolism to repair and reinforce materials. MICP is considered to be a more environmentally friendly, sustainable and highly promising repair method, and has received widespread attention and application in many fields such as geology, civil engineering, water conservancy, and environment.

[0003] The calcium carbonate precipitate generated by MICP technology has excellent consolidation properties and can be used to repair bridge cracks. It can cover the uneven surface inside the cracks and bond firmly.

[0004] When cracks appear on bridges, the existing repair measures are often to use pipes to inject emulsions containing microorganisms into the cracks. However, many cracks run through the bridge body and are prone to leakage. If baffles are installed under the cracks, additional drilling and time-consuming and laborious fixation with expansion screws are required, which is not convenient for the quick repair of through-the-bridge cracks. For this reason, we propose a bridge crack repair device that uses microorganisms. Utility Model Content

[0005] The purpose of the utility model is to provide a bridge crack repair device using microorganisms, which can seal the cracks at one time to form a pouring space without the need for additional expansion screws to fix them, and stably store emulsions containing microorganisms, thereby facilitating the quick repair of through-cracks in bridges.

[0008] The steel ring is provided with a sleeve fixedly connected to the top plate, which can tighten the steel ring and facilitate the steel ring to swing around it.

[0009] A plurality of upper protrusions are fixed on the upper surface of the bottom plate, and a plurality of lower protrusions are fixed on the lower surface of the top plate. Both the lower protrusions and the upper protrusions can be made of rubber material, which can be deformed for buffering and has good friction with the bridge surface, thereby facilitating anti-slip.

[0010] Washers are fixed at the connection between the bottom plate and the sling to strengthen the connection and prevent disconnection.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-4 As shown, a bridge crack repair device using microorganisms includes a bottom plate 1, a plurality of slings 2, a top plate 3 and a steel ring 4 arranged in sequence from bottom to top. The sling 2 can be made of steel wire or nylon rope and can be cut with strong scissors. The sling 2 is fixedly connected to the bottom plate 1. The bottom plate 1 and the top plate 3 can both be made of hard plastic plate, which is light and easy to carry and can bypass the protruding part in the crack. The steel ring 4 is rotatably connected to the top plate 3, and the number of the steel ring 4 can be at least one. The top plate 3 is provided with a threading hole 5 and a pouring port 6 staggered from the threading hole 5. The slings 2 pass through the threading hole 5 upwards to tie the steel ring 4. The emulsion containing microorganisms prefabricated based on the MICP technology can be put into a bag When repairing a through crack in a bridge, the bottom plate 1 can be used to seal the lower opening of the crack, and the slings 2 can be passed upward through the crack and the threading holes 5 of the top plate 3, and then the top plate 3 can be used to seal the upper opening of the crack, and the slings 2 can be passed around the adjacent steel rings 4 until the bottom plate 1 and the top plate 3 are tightened and the steel rings 4 are tied. This can close the crack at one time to form a pouring space, and then the pouring port 6 can be opened from the outside, and the bagged emulsion can be torn open and poured into the pouring space along the pouring port 6. The pouring port 6 is closed, and calcium carbonate precipitation is produced under the action of microorganisms, which gradually hardens in the pouring space to fill the through crack. No additional expansion screws are needed to fix it, and the emulsion with microorganisms can be stably stored, which is convenient for the quick repair of through cracks in bridges.

[0023] At the same time, the bagged emulsion containing microorganisms can refer to the Chinese utility model announcement number CN220246709U, which records the use of a liquid storage bag and an infusion tube. Opening the infusion tube can allow the bagged emulsion containing microorganisms in the liquid storage bag to flow out, and then close the infusion tube; after the emulsion hardens in the pouring space, the sling 2 can be cut with steel scissors, which facilitates the removal of the top plate 3 for demoulding, thereby reducing the obstruction to vehicles on the bridge, and the bottom plate 1 is located under the bridge and does not produce any obstruction.

[0024] like Figure 1 and Figure 2As shown, the steel ring 4 is provided with a sleeve 7 fixedly connected to the top plate 3. The sleeve 7 can be made of stainless steel, which is not easy to rust. It can tighten the steel ring 4 and facilitate the steel ring 4 to swing around it. After falling down, it can be close to the surface of the bridge. The thickness is small and it is not easy to cause obvious cushioning feeling.

[0025] like Figure 2 and Figure 4 As shown, a plurality of upper protrusions 8 are fixed on the upper surface of the bottom plate 1, and a plurality of lower protrusions 9 are fixed on the lower surface of the top plate 3. Both the lower protrusions 9 and the upper protrusions 8 can be made of rubber material, which can be deformed for buffering and has good friction with the bridge surface, thereby facilitating anti-slip.

[0026] like Figure 1 and Figure 2 As shown, washers 10 are fixed at the connection between the base plate 1 and the sling 2 to strengthen the connection and prevent disconnection.

[0027] like Figure 1 and Figure 4 As shown, a sealing ring 11 is fixed to the lower edge of the top plate 3. The sealing ring 11 surrounds the lower protrusion 9 and fits with the upper surface of the bridge, cooperating with the top plate 3 to surround the upper opening of the crack to seal it and reduce the infiltration of rainwater.

[0028] like Figure 1 and Figure 3 As shown, a rubber plug 12 is inserted into the opening of the pouring port 6. The rubber plug 12 is elastic and can have an interference fit with the pouring port 6, making it easy to plug and unplug.

[0029] The working principle of the utility model is as follows: when repairing a through crack in a bridge, the bottom plate 1 can be used to seal the lower opening of the crack, the slings 2 can be passed upward through the crack and the threading holes 5 of the top plate 3, and then the top plate 3 can be used to seal the upper opening of the crack, and the slings 2 can be passed around the adjacent steel ring 4 until the bottom plate 1 and the top plate 3 are tightened and the steel ring 4 is tied, so that the crack can be closed at one time to form a pouring space.

[0030] Then, the pouring port 6 is opened from the outside, and the bagged emulsion can be torn open and poured into the pouring space along the pouring port 6. The pouring port 6 is closed, and calcium carbonate precipitation is produced under the action of microorganisms, which gradually hardens in the pouring space to fill the through cracks. No additional expansion screws are needed to fix it. The emulsion with microorganisms can be stably stored, which is convenient for the quick repair of the through cracks in the bridge.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
