Description

Technical field:

[0001] The utility model relates to the field of roadbed reinforcement, in particular to a roadbed reinforcement mechanism for bridge construction. Background technology:

[0002] As traffic volume and vehicle weight increase, the bearing capacity of bridges and roadbeds may be insufficient, leading to structural failure, deformation or collapse. By reinforcing bridge roadbeds, their bearing capacity can be enhanced, making them safer and more reliable.

[0003] The utility model patent with publication number CN212714330U discloses a road bridge inspection roadbed reinforcement structure. The reinforcement structure is provided with a diversion port between the reinforcement plates and a plurality of drainage holes on the pressure plate. The infiltrated rainwater flows into the drainage hole through the diversion port and finally flows into the drainage pipe in the protective slope under the action of the diversion plate.

[0004] However, the diversion ports in the reinforcement structure absorb rainwater through the flow of rainwater itself, and the diversion ports are dispersed. After rainwater penetrates into the roadbed, it is difficult to flow into the diversion ports again, resulting in poor drainage. At the same time, a large area of ​​reinforcement plates is required to reinforce the roadbed, which consumes a lot of consumables and has high construction costs. Summary of the invention:

[0005] The technical problem to be solved by the utility model is to provide a roadbed reinforcement mechanism for bridge construction which has good drainage effect and small amount of consumables.

[0006] The purpose of the utility model is achieved in this way: it includes a water pumping pipe, a transverse pipe groove is opened in the roadbed and the slopes on both sides thereof, the water pumping pipe is placed in the pipe groove, and one end of the water pumping pipe is connected to the pump through a connecting pipe.

[0007] The pump is fixed in a placement groove at the bottom of the slope. A cover plate is provided on the placement groove, which is threadedly connected to the slope. A drainage pipe connected to the drainage outlet of the pump extends from the slope. The connecting pipe extends from the cover plate into the placement groove and is connected to the pump.

[0008] A number of evenly distributed vertical diversion ports are provided in the roadbed above and below the water pumping pipe, each of which is provided with a diversion pipe, each of which is connected with the water pumping pipe, and a plurality of branch pipes are provided on the side wall of each diversion pipe, and the diversion ports are provided with openings at positions corresponding to the branch pipes, and the other ends of the branch pipes extend from the openings of the diversion ports and then extend into the interior of the roadbed.

[0009] In order to avoid the blockage of the pumping pipe due to the suction of sand and gravel inside the roadbed during pumping, a pumping and filtering mechanism can be set in the branch pipe. The pumping and filtering mechanism includes a filter screen, which is fixed in the branch pipe. A cross bar passes through the middle of the filter screen, and the cross bar is rotatably connected to the filter screen. Fan blades are fixed on the cross bar located on the inner side of the filter screen (the side facing the guide pipe), and a scraper is fixed on the cross bar located on the outer side of the filter screen (the side facing the roadbed), and the scraper is in contact with the filter screen.

[0010] In order to support and reinforce the inside of the roadbed, a reinforced concrete bracket is arranged between the diversion pipe and the diversion port, and two connecting rods are symmetrically fixed on the upper end of the outer wall of the diversion pipe. A positioning ring is also included and arranged on the outer side of the upper end of the diversion pipe. The other ends of the two connecting rods are fixed on the inner wall of the positioning ring, and the positioning ring is in contact with the inner wall of the diversion port.

[0011] The reinforced concrete support is provided with an avoidance through hole at a position corresponding to the branch pipe.

[0012] The advantages of the utility model are:

[0013] The water pumping pipe, diversion port and diversion pipe are set up to support and reinforce the inside of the roadbed with the help of reinforced concrete brackets. Through the cooperation of multiple branch pipes and pump body, the seepage inside the roadbed can be actively sucked out, with good drainage effect, which can avoid excessive seepage inside the roadbed to affect the overall strength of the roadbed. In addition, there is no need to set up a large area of ​​reinforcement plates for roadbed reinforcement, which reduces the amount of consumables.

[0014] By installing a filter in the branch pipe, sand and gravel inside the roadbed can be avoided from being sucked into the water when the water is pumped. At the same time, under the suction of the pump body, the suction force drives the impeller to rotate, so that the scraper can scrape the surface of the filter to avoid clogging of the filter.

[0020] The pump is fixed in a placement groove 4 at the bottom of the slope, and a cover plate 5 is provided on the placement groove. The cover plate is threadedly connected to the slope, and a drainage pipe 6 connected to the drainage outlet of the pump extends out from the slope; the cover plate can cover and protect the pump, and try to avoid the pump from being damaged by foreign objects, thereby ensuring that the pump can be used continuously and stably; the connecting pipe extends from the cover plate into the placement groove and is connected to the pump.

[0021] A number of evenly distributed vertical diversion ports 7 are provided in the roadbed above and below the water pumping pipe, each of which is provided with a diversion pipe 8, each of which is connected to the water pumping pipe, and a plurality of branch pipes 9 are provided on the side wall of each diversion pipe, and the diversion ports are provided with openings at positions corresponding to the branch pipes, and the other ends of the branch pipes extend from the openings of the diversion ports and then extend into the roadbed. During the use of the roadbed, the pump is started, and the rainwater and other liquids that have infiltrated into the roadbed can be actively sucked out through the cooperation of the water pumping pipe, the diversion pipe and the branch pipe, so as to avoid the accumulation of liquids in the roadbed and affect the overall structure of the roadbed, and to provide auxiliary reinforcement for the roadbed to ensure the stability of the roadbed in long-term use.

[0022] In order to avoid the blockage of the water pumping pipe caused by the suction of sand and gravel inside the roadbed during water pumping, a water pumping and filtering mechanism can be set in the branch pipe, which includes a filter screen 10, which is fixed in the branch pipe, and a cross bar 11 passes through the middle of the filter screen, which is rotatably connected with the filter screen, and a fan blade 12 is fixed on the cross bar located on the inner side of the filter screen (the side facing the guide pipe), and a scraper 13 is fixed on the cross bar located on the outer side of the filter screen (the side facing the roadbed), and the scraper is in contact with the filter screen. When the water is pumped, the water can be filtered through the filter screen, and the pump body is started.
