[0002] Bridge construction is the process of building a bridge according to the design content; it mainly refers to bridge construction technology and construction organization, construction management, construction quality and other contents.

[0003] Before starting bridge construction, a circle of barriers needs to be built around the work site to prevent non-staff from entering the work site, and also to intercept the dust generated during work. Traditional enclosure structures generally include a counterweight part and an interception part. The counterweight part is mainly made of cement blocks, and the interception part is a metal baffle.

A group of water mist dust-proof structures are arranged among 3-5 bases. The clean water inside the cavity can be pumped out by a diversion pump and then used for spray dust reduction. Therefore, the dust reduction treatment can be carried out with the help of the water stored inside the base, and the difficulty of arranging the dust-proof structure can be reduced. At the same time, in the process of pumping out the clean water inside the cavity, it is necessary to keep the cavity continuously filled with water, so as to ensure the stability of the counterweight of the base and meet the requirements of the water mist dust-proof structure. 3. A three-dimensional filter is arranged in the second connecting pipe for diversion, which can intercept impurities in the water. At the same time, the turning handle can be rotated through the transmission rod, thereby driving the brush plate to rotate, and the impurities on the three-dimensional filter are brushed off by the brush plate, so as to achieve deep cleaning of the filter, ensure the normal operation of the entire diversion system, and the cleaned impurities can be concentrated inside the waste storage pipe, which is convenient for the subsequent centralized cleaning of impurities; 4. The third connecting pipe is provided with a spiral guide plate inside. When clean water flows through the inside, a torque will be generated on the pipe, causing the pipe to rotate, thereby driving the nozzle to rotate together. During the rotation process, the spraying range of the water mist can be increased without generating energy consumption. At the same time, blades that can rotate together are also provided on one side of the nozzle. When the blades rotate, the flow rate of the airflow can be accelerated, and the airflow can be used to drive the water mist to drift to a farther position, thereby increasing the range of the water mist and improving the dust reduction effect.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] See also Figures 1 to 6 , an embodiment of the present invention provides a bridge construction safety protection isolation device, the bridge construction safety protection isolation device includes a fixed base structure 1, an auxiliary tripod structure 2, an isolation baffle structure 3 and a water mist dustproof structure 4; The isolation baffle structure 3 is fixed on the fixed base structure 1 through the auxiliary support structure 2; The fixed base structure 1 includes a base 11, which is made of polyethylene material. The base 11 has a cavity 12 inside, and the cavity 12 is used to store clean water for counterweight. A reinforcing plate 14 is integrally connected to one side of the base 11. The upper end of the base 11 has a deep groove 15 away from the center, and the upper end also has a strip groove 18 along the length direction. The strip groove 18 is connected to the deep groove 15. A first positioning rod 16 and a second positioning rod 17 are vertically fixed inside the deep groove 15. The length of the second positioning rod 17 exceeds the depth of the deep groove 15 and extends to the top of the deep groove 15. A tightening nut 19 is also threadedly connected. Both ends of the base 11 have grooves, and the bottom of the groove has a pipe connected to the internal cavity 12 of the base 11. The folding hose 13 is sleeved on the pipe to achieve communication between two adjacent bases 11. When the two adjacent bases 11 are close to each other, the folding hose 13 is completely inside the groove.

[0022] It should be noted that: in the device, the fixed base structure 1 is used as the basic counterweight structure, and the base 11 is used as the positioning base in the structure. The whole is made of polyethylene material, and there is a cavity 12 inside it. Therefore, the entire base 11 is a cavity shell structure, so that when carrying out transportation operations, handling operations and arrangement operations, the consumption of manpower will be lower and it will be more convenient; The side of the base 11 has a groove structure, and a pipe connected to the internal volume 12 of the base 11 is arranged inside the groove, and a folding hose 13 is sleeved on the pipe, and the volume 12 between adjacent bases 11 is connected through the folding hose 13. Therefore, after the side-by-side arrangement of the bases 11 is completed, a water pump is connected to the outermost base 11, and then clean water is introduced into the base 11, and the clean water enters the remaining bases 11 through the folding hose 13, so that all the bases 11 can be filled. After being filled with water, the weight of the entire base 11 increases, meeting the demand for counterweight use. After the arrangement of the bases 11 is completed, the auxiliary tripod structure 2 is fixed to the base 11, and then the isolation baffle structure 3 is fixed to the auxiliary tripod structure 2, thereby completing the assembly of the entire enclosure structure; A reinforcing plate 14 is also provided on the side of the base 11. The reinforcing plate 14 has holes so that pins can be driven into the soil. Therefore, if the enclosure is used on an uneven muddy ground, the stability of the entire base 11 can be further improved. The water mist dust-proof structure 4 is fixed on the base 11, and can extract clean water from the cavity 12 and then spray it out in a mist form, so as to perform dust reduction operations on the workplace; at the same time, a water mist dust-proof structure 4 is set between 3-5 enclosure structures, which can shorten the use length of the pipeline and reduce the pipeline laying operation. Moreover, when the bridge construction operation is about to be completed, all the clean water inside each base 11 can be extracted and used for dust reduction, avoiding the waste of water resources.

[0023] In the embodiments of the present invention, please refer to Figure 7 The auxiliary tripod structure 2 includes an I-shaped connecting plate 21, both ends of which are integrally connected to an assembly base 22. The I-shaped connecting plate 21 and the assembly base 22 are respectively embedded in the strip groove 18 and the deep groove 15. The upper end surfaces of the I-shaped connecting plate 21 and the assembly base 22 are flush with each other, and are also flush with the upper end surface of the base 11. A slot 23 and a through hole 24 for inserting the first positioning rod 16 and the second positioning rod 17 are also provided at the lower end of the assembly base 22. The second positioning rod 17 passes through the through hole 24 and is fixed by tightening the nut 19. A plurality of third positioning rods 25 are vertically fixed to the upper end of the I-shaped connecting plate 21.

[0024] It should be noted that: for the installation of the auxiliary tripod structure 2, its I-shaped connecting plate 21 and the assembly base 22 can be embedded in the strip groove 18 and the deep groove 15 to achieve preliminary installation. At the same time, there is a first positioning rod 16 and a second positioning rod 17 in the deep groove 15, both of which can be inserted into the slot 23 and the through hole 24 in the assembly base 22. At the same time, the second positioning rod 17 can pass through the through hole 24 and is reinforced by tightening the nut 19 to achieve the installation of the auxiliary tripod structure 2. In addition, the auxiliary tripod structure 2 is made of metal and can act as a counterweight.

[0025] In the embodiments of the present invention, please refer to Figure 8 The isolation baffle structure 3 includes an outer positioning frame 31, and the lower end of the outer positioning frame 31 has a hole adapted to the third positioning rod 25. The third positioning rod 25 passes through the hole and is fixed by a nut. A baffle 33 for interception is fixed by rivets on one side of the outer positioning frame 31. A vertically arranged auxiliary plate 32 is also fixed on one side of the outer positioning frame 31, and a bracket 34 is fixed on one side of the auxiliary plate 32.

[0026] It should be noted that the isolation baffle structure 3 is a relatively traditional baffle structure, with an external positioning frame 31 as a basic frame structure, and a baffle 33 made of metal sheets fixed thereon, so that the work site can be enclosed, and its installation operation is also relatively convenient.

[0027] In the embodiments of the present invention, please refer to Figures 9 to 13 , the water mist dustproof structure 4 includes a guide part and a rotary jet part; The diversion part includes a diversion pump 41, which is fixed on the base 11. A first connecting pipe 42 is fixed at the input end of the diversion pump 41. The other end of the first connecting pipe 42 has a horizontal second connecting pipe 43. The second connecting pipe 43 is arc-shaped near the other end and faces obliquely upward. It is also fixed to the outside of the base 11 and communicates with the cavity 12 inside the base 11, and cooperates with the diversion pump 41 to pump out the clean water in the cavity 12. A first flow guide pipe 410 is fixed at the output end of the flow guide pump 41, and the other end of the first flow guide pipe 410 is connected to a horizontally arranged second flow guide pipe 411. The second flow guide pipe 411 is mounted on the bracket 34, and one end is closed, and the other end is fixed with an external pipe 412, and is connected to another second flow guide pipe 411 through the external pipe 412. A plurality of equally spaced positioning pipes 413 are also fixed on the circumferential outer wall of the second flow guide pipe 411; At the same time, a three-dimensional filter screen 44 is fixed inside the second connecting tube 43 and near the arc-shaped area, and a concentric transmission rod 45 is rotatably connected thereto. One end of the transmission rod 45 passes through the three-dimensional filter screen 44, and a plurality of ring-shaped brush plates 47 are fixed to the end. The brush plates 47 contact the three-dimensional filter screen 44 and are used to scrape off impurities attached to the three-dimensional filter screen 44. The other end passes through the second connecting tube 43 and extends to the outside thereof, and a handle 46 is fixed to the end. A communicating waste storage pipe 48 is fixed on the outer circumferential wall of the second connecting pipe 43 and at a position corresponding to the three-dimensional filtering screen 44 , and a valve pipe 49 is fixed on the lower end of the waste storage pipe 48 .

[0028] It should be noted that: for the guide part in the water mist dustproof structure 4, the guide pump 41 is a power device, which extracts clean water from the inside of the cavity 12 through the first connecting pipe 42 and the second connecting pipe 43, and then introduces it into each second guide pipe 411 through the first guide pipe 410. In this process, the three-dimensional filter 44 in the first connecting pipe 42 can be used to intercept impurities to prevent impurities from entering the rotating jet part, thereby preventing clogging; At the same time, when too many impurities are intercepted at the three-dimensional filter 44 and affect the flow of water, the turning handle 46 drives the transmission rod 45 to rotate, and then drives each brush plate 47 to rotate. The brush plate 47 contacts the three-dimensional filter 44, and can scrape off the impurities attached to it during the rotation process. The cleaned impurities will fall into the waste storage pipe 48. After the valve pipe 49 is opened, the impurities can be discharged in a concentrated manner, thereby achieving deep cleaning of the impurities. The first connecting pipe 42 has an arc section, and the three-dimensional filter screen 44 and the waste storage pipe 48 are both close to the arc section, so the intercepted impurities can be prevented from flowing back into the cavity 12, thereby improving the cleaning effect of the impurities.

[0029] In the embodiments of the present invention, please refer to Figure 13 to Figure 14 The rotary jet part includes a third connecting pipe 415, which is rotatably mounted on the other end of the positioning pipe 413 through a rotary sealing joint 414, and a spiral guide plate 416 is fixed on the inner wall of the circumference of the third connecting pipe 415. The other end of the third connecting pipe 415 has a nozzle 417, which is in the shape of a circular plate and has a plurality of eagle-beak-shaped spray holes on the outer wall of the circumference. A sleeve 418 is fixed on one side of the nozzle 417, and the sleeve 418 is sleeved on the third connecting pipe 415; An outer ring frame 419 is also fixed to the circumferential outer wall of the sleeve 418, and a plurality of blades 420 are fixed to the circumferential outer wall of the outer ring frame 419. The blades 420 rotate along with the nozzle 417 to increase the flow rate of the airflow.

[0030] It should be noted that the third connecting pipe 415 and the positioning pipe 413 are connected via a rotating sealing joint 414, so the third connecting pipe 415 can rotate, and a spiral guide plate 416 is arranged inside the third connecting pipe 415. When clean water flows through the third connecting pipe 415, a force is generated on the spiral guide plate 416, and then a torque is generated on the entire third connecting pipe 415, so that the third connecting pipe 415 can rotate. This process does not generate energy consumption, and the rotation of the third connecting pipe 415 drives the nozzle 417 to rotate together. When the nozzle 417 rotates, the spraying range of the spray can be increased; The blade 420 disposed on the back side of the nozzle 417 will rotate together with the nozzle 417. The blade 420 can accelerate the airflow velocity when rotating. Under the action of the airflow, the water mist can be blown to a farther position, increasing the effective range of the water mist, thereby further improving the dust reduction effect.

[0031] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
