Description

Technical Field

[0001] This utility model relates to the field of road grouting technology, and in particular to a portable road device based on a two-component green grouting material. Background Technology

[0002] In road construction, the performance of grouting materials plays a crucial role in the reinforcement effect. Cement grouting, due to its low cost, wide availability, and simple construction process, is widely used in practical projects. However, it also has certain drawbacks. For example, cement grouting suffers from slow early strength formation, difficulty in controlling stability and fluidity, and a tendency to segregate, especially in areas with high soil moisture content, where it is easily diluted by groundwater, severely affecting grouting quality and effectiveness. Furthermore, cement production emits large amounts of greenhouse gases such as carbon dioxide, resulting in high pollution and energy consumption, far from my country's goal of achieving carbon neutrality. Alkali-activated geopolymers, with their high early strength and acid / corrosion resistance, are a green cementitious material that can replace silicate cement. However, because alkali-activated geopolymers have a short gelation time and rapid strength formation after forming the grouting material, once solidification occurs, they cannot be used for on-site construction, resulting in waste of raw materials and disrupting normal construction progress. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a portable road-use device based on a two-component green grouting material, suitable for use with alkali-activated geopolymers. Specifically, the following technical solution can be adopted:

[0004] The portable road-use device based on a two-component green grouting material of this utility model includes a handcart. An electrical control box, a liquid storage tank, and a mixing tank are mounted on the support plate of the handcart. A liquid inlet is located at the top of the liquid storage tank. The liquid storage tank and the mixing tank are connected via a liquid outlet pipe. A pump and a first flow sensor are mounted on the liquid outlet pipe. A stirrer connected to a rotary motor is located inside the mixing tank. A grouting conduit connected to a grouting pump is located at the bottom of the mixing tank. A pressure sensor and a second flow sensor are mounted on the grouting conduit. A rechargeable battery and a PLC are located inside the electrical control box. The rechargeable battery supplies power to the pump, the rotary motor, the grouting pump, the first flow sensor, the second flow sensor, and the pressure sensor. The signal output terminals of the first flow sensor, the second flow sensor, and the pressure sensor are respectively connected to the signal input terminal of the PLC. The control output terminal of the PLC is respectively connected to the control input terminals of the pump, the rotary motor, and the grouting pump.

[0005] The electrical control box is equipped with an LCD screen, a power switch, a liquid injection switch, a mixing switch, and a grouting switch. The power switch is located on the output circuit of the rechargeable battery, the liquid injection switch is located on the connection circuit between the rechargeable battery and the liquid pump, the mixing switch is located on the connection circuit between the rechargeable battery and the rotary motor, and the grouting switch is located on the connection circuit between the rechargeable battery and the grouting pump.

[0006] The liquid storage tank is equipped with a level gauge, and the liquid outlet pipe extends upward from the bottom of the liquid storage tank and connects to the top of the side wall of the mixing tank.

[0007] The mixing tank is equipped with a movable top cover, and the agitator includes a rotating shaft and two sets of upper and lower mixing blades disposed thereon. The mixing blades are all arc-shaped blades with the same rotation direction, and the mixing blades in the same set are evenly distributed along the circumference.

[0008] A hollow liquid distributor is sleeved on the rotating shaft. The liquid distributor is located above the stirring blades. The side of the liquid distributor is connected to the output end of the liquid outlet pipe. A liquid injection port is provided at the bottom of the hollow liquid storage chamber.

[0009] This utility model provides a portable road-use device based on a two-component green grouting material. It stores solid raw materials rich in aluminosilicates, such as slag, fly ash, and red mud, separately from a liquid-phase alkaline activator. When grouting is needed, the two are mixed and stirred evenly to form a grouting material for immediate use, avoiding the phenomenon of grout solidification rendering it unusable. During the grouting material preparation process, flow sensors and pressure sensors are installed on the pipeline to monitor the grouting pressure, flow rate, and grout ratio in real time, enabling dynamic adjustment to ensure stable grouting parameters and improve construction quality. This utility model has a simple structure and is easy to use. Road operations are carried out using a handcart, allowing for simultaneous preparation and pouring of the grouting material. It effectively controls the activation time of the aluminosilicate raw materials, allowing the grouting material to fully utilize its advantages of short gelation time and rapid strength formation, avoiding material waste and ensuring project quality.

[0012] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific working processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0013] like Figure 1 , 2 As shown, the portable road equipment based on two-component green grouting material of this utility model includes a handcart 1, and an electrical control box 2, a liquid storage tank 3 and a mixing tank 4 are provided on the support plate of the handcart 1.

[0014] Liquid storage tank 3 is used to store the liquid phase alkaline activator. A level gauge is installed on liquid storage tank 3 to monitor the liquid level. The top of liquid storage tank 3 is provided with a liquid inlet 31 (which can also serve as a vent) and a liquid outlet. A flexible section of liquid outlet pipe 32 is inserted into the liquid outlet, with one end extending to the bottom of liquid storage tank 3 and the other end connected to the liquid inlet at the top of the side wall of stirred tank 4. Inside stirred tank 4, a metal pipe connected to the liquid inlet serves as a rigid section of outlet pipe 32, on which a liquid pump 5 is installed. Stirred tank 4 uses a removable top cover for easy loading of solid raw materials.

[0015] A stirrer connected to a rotary motor 61 is installed inside the mixing tank 4. The stirrer includes a rotating shaft 62 mounted on the bottom plate of the tank, and two sets of stirring blades 63 mounted on the rotating shaft 62. All stirring blades 63 are arc-shaped blades with the same rotation direction, and the blades in the same set are evenly distributed circumferentially. The distance between the end of each stirring blade 63 and the side wall of the mixing tank 4 is maintained at 2-3 cm, allowing for the scraping and removal of adhering substances from the inner wall. A liquid distributor 7 is sleeved on the rotating shaft 62, positioned above the stirring blades 63. The liquid distributor 7 has a hollow structure, with its side connected to the output end of the rigid section of the liquid outlet pipe 32, and a liquid spray nozzle at its bottom. When the alkaline activator in liquid phase is transported from the liquid storage tank 3 to the mixing tank 4, it can be evenly sprayed from the center of the tank outwards through the liquid distributor 7, increasing the contact area between the solid and liquid phases and improving the uniformity of mixing. In addition, the structure connecting the rotating shaft 62, liquid distributor 7, and outlet pipe 32 via rigid pipe sections provides mutual support, improving the operational stability of the various devices inside the mixing tank 4. The aforementioned liquid pump 5 and rotary motor 61 are both located inside the tank, minimizing operating noise and reducing noise pollution to the surrounding environment. Based on their working environment, both the liquid pump 5 and rotary motor 61 must be dustproof and waterproof. The bottom of the mixing tank 4 is also equipped with a grouting conduit 8 connected to the grouting pump 81 for pouring the prepared grouting material onto the working surface.

[0016] A first flow sensor 91 is installed on the liquid outlet pipe 32, and a pressure sensor 92 and a second flow sensor 93 are installed on the grouting conduit 7. The electrical control box 2 houses a rechargeable battery and a PLC. The rechargeable battery supplies power to the pump 5, rotary motor 61, grouting pump 81, first flow sensor 91, second flow sensor 92, and pressure sensor 92. The signal output terminals of the first flow sensor 91, second flow sensor 93, and pressure sensor 92 are respectively connected to the signal input terminals of the PLC. The control output terminals of the PLC are respectively connected to the control input terminals of the pump 5, rotary motor 61, and grouting pump 81. Furthermore, the electrical control box 2 is equipped with an LCD screen, a power switch, a liquid injection switch, a mixing switch, and a grouting switch. The power switch is located on the output circuit of the rechargeable battery, the liquid injection switch is located on the connection circuit between the rechargeable battery and the pump 5, the mixing switch is located on the connection circuit between the rechargeable battery and the rotary motor 61, and the grouting switch is located on the connection circuit between the rechargeable battery and the grouting pump 81. The LCD screen displays monitoring data such as flow rate and pressure.

[0017] The solid raw materials mentioned above are industrial waste materials rich in aluminosilicates, such as slag, fly ash, and red mud. After grinding, they are screened through a 45μm square hole sieve until the sieve residue rate is below 10%. They are then put into the mixing tank 4, a certain amount of water is added, and the mixture is stirred evenly. Before this, sodium silicate reagent, 98% sodium hydroxide, and deionized water are mixed according to the design ratio to the optimal modulus and then injected into the liquid storage tank 3 for storage. After the solid raw materials are stirred, the rotary motor 61 is kept in working condition, and the liquid pump 5 is turned on to add the liquid-phase alkaline activator in the liquid storage tank 3 into the mixing tank 4. After stirring for a certain period of time, the grouting pump 81 is turned on to inject the prepared grouting material into the working face. When the pump 5 is working, the amount of liquid alkaline activator added is monitored by the first flow sensor 91. During the grouting process, the flow rate and pressure of the grout are monitored by the second flow sensor 93 and the pressure sensor 92, and the viscosity is converted and compared with the preset value. When it deviates from the preset value, a sample is taken for analysis. According to the monitoring results, the corresponding raw materials are added to readjust the grout to ensure the quality of the grout.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1) Storing alkaline activators and solid waste materials separately can better control the gelation time and strength forming time of the grouting liquid, greatly improving the fluidity of the grouting material and the controllability of the solidified body strength;

[0020] 2) Portable road equipment based on two-component green grouting materials can flexibly use minerals rich in aluminosilicates such as slag, fly ash, and red mud as raw materials for the production of grouting materials. Compared with traditional silicate cement, the effective use of geopolymers can not only reduce carbon emissions, alleviate resource and environmental pollution pressures, and meet the sustainable development needs of modern industry, but also solve the problem of large-scale industrial waste disposal, which is of great significance for building a resource-saving and environmentally friendly society.
