Technical Field

[0002] Cut-and-cover station is a method of construction that uses the open-cut method in the construction of subway stations. Its advantages are easy design and fast construction. The cut-and-cover method refers to digging the ground during subway construction, excavating earth and stone from top to bottom to the designed elevation, and then carrying out structural construction from the bottom to top. After the underground main structure is completed, the foundation pit is backfilled and the ground is restored. The construction process of the cut-and-cover station includes the construction of the retaining structure, dewatering, layered excavation and support, and the completion of the concrete pouring of the side walls, middle plates, and top plates of the structure. The cut-and-cover method is mainly suitable for areas with good geological conditions, low groundwater levels, or areas that can be effectively controlled. The construction technology is mature and widely used. During the construction process, plain concrete is usually required for pouring.

[0003] The existing technology has defects: during the mixing and stirring process of plain concrete, if the raw materials contain large particles, the locking force of the concrete will be poor and the porosity will be large, thus affecting the uniformity and strength of the concrete; incomplete stirring of the plain concrete during mixing will lead to problems such as insufficient concrete strength and easy cracking; when the plain concrete is poured, due to the different specific gravities of various materials in the raw materials, the coarse aggregate in the concrete will sink and accumulate at the discharge port, causing the discharge port to be blocked, affecting work efficiency, and at the same time affecting the homogeneity of the concrete, reducing the strength and durability of the concrete.

The pawl slides on the ratchet 382, ​​and the rotating rod 372 drives the scraper 374 and the drainage fan 389 to rotate. The scraper 374 sweeps away the large particles on the surface of the first filter disc 371 to prevent the large particles from blocking the filter holes of the first filter disc 371. The drainage fan 389 drives the concrete to flow upward, so that the large particles in the concrete enter the crushing blocks. The crushing blocks on the first crushing barrel 331 and the second crushing barrel 332 crush the large particles into broken particles, and the broken particles enter between the second filter disc 378 and the first filter disc 371 from the filter holes of the first filter disc 371.

[0042] When the transmission rod 32 rotates, the transmission rod 32 drives the first gear 34 to rotate, the first gear 34 drives the belt 35 to rotate, the belt 35 drives the second gear 36 to rotate, the second gear 36 drives the first rotating shaft 375 to rotate, the first rotating shaft 375 drives the first connecting rod 376 to rotate, the first connecting rod 376 drives the second connecting rod 377 to rotate, the second connecting rod 377 drives the second filter disc 378 to slide along the rotating rod 372, the second filter disc 378 reciprocates and hits the first filter disc 371, grinding the broken particles into small particles, and the small particles fall into the mixing device 38 from the filter holes of the second filter disc 378.

[0043] When small particles enter the mixing device 38, the first motor 4 is controlled to reverse, the first motor 4 drives the transmission rod 32 to reverse, the transmission rod 32 drives the third worm gear 373 to reverse, the third worm gear 373 drives the rotating rod 372 to reverse, the pawl on the rotating rod 372 drives the ratchet 382 to rotate, the ratchet 382 drives the sleeve rod 381 to rotate, the sleeve rod 381 drives the first stirring block and the first bevel gear 384 to rotate, the first bevel gear 384 drives the second bevel gear 385 to rotate, the second bevel gear 385 drives the third bevel gear 386 to rotate, the third bevel gear 386 drives the second rotating shaft 388 to rotate, the second rotating shaft 388 and the sleeve rod 381 rotate in opposite directions, the second rotating shaft 388 drives the second stirring block to rotate, the drainage fan 389 rotates in the opposite direction, drives the concrete to flow downward, makes the concrete shake up and down in the mixing device 38, the first stirring block and the second stirring block fully stir the concrete, after the concrete is fully stirred, the first discharge valve is controlled to open, and the concrete enters the second protective shell 51 from the first feeding port 39.

[0044] After a period of time when the concrete enters the second protective shell 51, the control system controls the second motor 6 and the electric heating network 53 to start, the output shaft of the second motor 6 drives the screw rod 52 to rotate, the screw rod 52 drives the fan 54 to rotate, the fan 54 blows the heat of the electric heating network 53 into the second protective shell 51 to heat and keep the concrete warm, and the hot air is blown out from the heat dissipation holes. At the same time, the screw rod 52 drives the lifting plate 561 to rise, the concrete presses the baffle 566 on the lifting plate 561, the small hole 563 blocks the particles, and the particles rise together with the lifting plate 561. The lifting plate 56 drives the particles deposited on the concrete bottom plate to move upward. When the lifting plate 56 reaches a predetermined height, the second motor 6 is controlled to reverse, the output shaft of the second motor 6 drives the screw rod 52 to reverse, the screw rod 52 drives the fan 54 to reverse, and the fan 54 draws air from the heat dissipation holes. Blow out to the filter plate 55 to blow out the dust, particles, etc. on the outside of the filter plate 55. At the same time, the screw rod 52 drives the lifting plate body 561 to descend. The concrete presses the baffle 566 on the limit block 565. The concrete can enter and exit from the filter port, reducing the pressure on the lifting plate body 561 until it descends to the initial position. The control system turns off the electric heating network 53. At this time, the particles in the concrete fall down to make the particles evenly distributed in the concrete. Repeat the above steps at regular intervals. When the lifting plate 56 reciprocates up and down, the dynamic circulation of the concrete material can be realized, which can not only avoid the stratification phenomenon caused by long-term deposition of particles, but also help maintain the uniformity of the concrete, and effectively prevent the blockage of the discharge port 7 caused by the particles sinking to the bottom. When concrete needs to be used, the second discharge valve is controlled to open, and the concrete enters the feeder through the discharge port 7.
