Abstract
Description
Technical Field
[0001] The present invention relates to the field of trapezoidal building block processing, and in particular to a production device for non-cement-based trapezoidal building blocks and a manufacturing method thereof. Background Art
[0002] Trapezoidal blocks are precast concrete components commonly used in farmland irrigation, drainage systems, or roadside ditches. The use of trapezoidal blocks can reduce water loss due to leakage and evaporation during water transportation, improving water resource utilization efficiency. Furthermore, their rapid water delivery shortens the irrigation cycle, thereby reducing electricity consumption during the irrigation process and achieving energy conservation. Trapezoidal channels have a scientifically designed cross-section, resulting in rapid water flow and strong water delivery capacity. The average flow rate can reach 0.6 to 0.9 meters per second, and the channel roughness value is approximately 0.013. Compared to U-shaped channels, they significantly improve water delivery efficiency and effectively reduce sedimentation.
[0003] Currently, the trapezoidal blocks sold on the market are mainly made using a pressing machine. This machine relies on the pressure of a pressing head to form the blocks. The special structure of the trapezoidal cross-section makes it difficult to completely expel internal bubbles, resulting in uneven block density and affecting the quality of batch molding. In addition, the raw materials need to be centrally prepared and mixed before being transferred to the molding machine for pressing, resulting in multiple processes and low efficiency. On the other hand, this type of trapezoidal block is currently usually made using high-content cement, aggregate and other materials. The high content of cement leads to relatively high raw material costs, which is not conducive to reducing construction costs. In addition, the high ambient temperature in summer makes the mixture prone to problems such as rapid slump loss, plastic shrinkage cracking, and excessively fast setting rate, which significantly increases the risk of temperature stress cracking. Under low temperature conditions in winter, there are common problems such as slow strength development and prolonged setting time, which greatly increases the possibility of frost damage and causes quality defects such as cracking and dislocation at the joints of prefabricated channels, affecting the service life of the channels.

[0025] The guide rail mechanism includes a channel steel guide rail 171 and a winch 173 arranged side by side. The side of the upper hopper 12 is connected to the wheel axle 126 through a rotating support 161. The outer end of the wheel axle is connected to a main guide wheel 124. The upper hopper 12 can rotate relative to the wheel axle 126 of the main guide wheel 124. The main guide wheel 124 is matched and connected in the channel steel guide rail 171.

[0027] The scraper 128 provided at the end of the stirring arm 132 is used to fully fit with the inner wall of the double-chamber cylinder 11, exerting sufficient scraping force on the inner wall to prevent non-cement-based building block raw materials from adhering to the inner wall of the double-chamber cylinder 11 and increasing the resistance of the stirring arm, thereby avoiding the phenomenon of the stirring arm 132 being blocked or stuck in the stirring chamber, thereby ensuring efficient and stable operation of the equipment.

The change in route drives the blocking plate 122 to flip over. The flipped blocking plate 122 drives the upper hopper 12 to rotate around the axle 126 of the main wheel 124. The lower port of the upper hopper 12 is opened, and the raw materials flow into the double-chamber cylinder 11. (3) The two stirring shafts 13 in the double-chamber cylinder 11 rotate in opposite directions to mix and stir the raw materials, and at the same time, the nozzle 114 on the water inlet pipe 113 sprays water evenly into the double-chamber cylinder 11 to evenly stir the block raw materials; (4) The cylinder 16 is started to push the arc-shaped rocker 162, which drives the arc-shaped rocker 162 to rotate the rotating shaft 155 of the roller door 15, and the arc plate 152 rotates away from the discharge port 111. The block raw materials enter the mold cavity inlet 24 of the trapezoidal mold 2 below from the hopper 5. The vibration force generated by the vibration platform 3 continuously discharges the gas in the raw materials, making the raw materials in a dense state; (5) After the trapezoidal mold 2 is filled with raw materials and cast into shape, the cylinder 16 is activated again to close the roller door 15, and then the handle 52 on the hopper 5 is held and pushed to slide outward along the slide rail 53, so that the hopper 5 leaves the mold cavity entrance 24 of the trapezoidal mold 2; (6) Use a forklift to drag the trapezoidal mold 2 horizontally from the vibration platform 3 and place it in the warehouse for curing. After the compressive strength reaches the requirement, remove the trapezoidal inner template 21 and the trapezoidal outer template 22, and the trapezoidal building block is completed.

Furthermore, the incorporated PP fibers create a three-dimensional, randomly distributed reinforcement network within the matrix, contributing to overall matrix stability. This material design strategy ensures construction operability (setting time ≥ 60 minutes) in high summer temperatures (daily temperatures ≥ 30°C) while also achieving low shrinkage and high crack resistance in high-temperature environments through a multi-scale reinforcement mechanism (molecular-level reaction regulation + macroscopic fiber toughening).
[0035] Example 4, a non-cement-based trapezoidal building block, the building block raw materials are calculated by weight and are composed of: 1.0 part of mud and sand, 1.0 part of gravel, 0.25-0.30 part of water glass with a modulus of 1.5, 0.80-0.90 part of S105 grade mineral powder, 0.18-0.22 part of water, 0.03-0.035 part of water reducer, and 0.015-0.020 part of PP-12mm fiber.
[0036] This embodiment addresses the technical difficulties of slow alkali-induced reaction rate and sluggish strength development in low-temperature winter environments. By optimizing the modulus of the activator and the alkali equivalent, dual regulation is achieved. On the one hand, the dissolution rate of the aluminosilicate precursor (such as mineral powder) under low-temperature conditions is improved; on the other hand, the condensation behavior of the dissolved products is controlled, which helps the orderly accumulation of the reaction products in low-temperature environments, thereby achieving rapid early strength development and stable long-term strength growth in low-temperature environments. The three-dimensional, randomly distributed network of incorporated PP fibers effectively inhibits the development of shrinkage microcracks in low-temperature environments, significantly improving the material's durability in freeze-thaw cycles. This design, through the synergistic effect of "chemically activated optimization + fiber reinforcement," addresses the construction and application challenges of non-cement-based materials in winter environments.
