[0002] Water flow engineering, also known as water conservancy engineering, is an engineering system that achieves goals such as flood control, irrigation, power generation, water supply, and soil and water conservation by controlling and allocating surface water and groundwater. Its core lies in using hydraulic structures (such as dams, spillways, channels, etc.) to regulate water flow and serve agricultural production, energy development, ecological protection and other fields.

[0003] Sidewalls are vertical structures used to restrict water flow and protect slopes in hydraulic structures. They are commonly found in spillways, chutes, dams, and other scenarios. As an important component of water flow engineering, the design, construction, and material selection of sidewalls directly affect the overall effect of water flow engineering. Reasonable sidewall design can ensure smooth water flow, reduce scouring and erosion, and improve the stability and safety of water flow engineering.

[0004] Traditional side wall construction technology requires the coordination of multiple steps, such as supporting formwork, dismantling formwork, concrete vibration, etc. The process is cumbersome and relies on manual operation. Summary of the invention

[0030] Step 2: Equipment positioning and leveling:

At the same time, the quick-setting agent spraying device sprays the quick-setting agent evenly onto the surface of the extrusion wall through air pressure control;

[0037] c. Monitor the forming speed in real time and control the auger speed by adjusting the diesel engine throttle to maintain the forming speed at 40-80 m / h;

[0038] Step 4: Dynamic adjustment and quality control:

[0039] a. Use the spring of the rear wheel mechanism to buffer ground impact, and adjust the ground clearance through the cylinder to adapt to the terrain;

[0040] b. Control the front wheel steering through the steering system, and correct the linearity of the extrusion wall by combining the vertical line detection of the base surface behind the forming chamber;

[0041] c. Adjust the pressure regulating valve according to the pressure value displayed on the barometer to ensure uniformity of the quick-setting agent spraying;

[0042] Step 5: Construction completion processing:

[0043] a. After stopping feeding, clean the residual concrete in the auger bin and the forming bin, empty the accelerator storage tank and flush the pipeline with clean water;

[0044] b. Shut down the diesel engine, lift it off the sidewall extruder and perform maintenance, including lubricating key components, checking welds and bolt tightness.

[0045] Preferably, the nozzle of the quick-setting agent spraying device in step 3 dynamically adjusts the spraying angle by adjusting the clamp to cover the forming surface of the extrusion wall with a slope ratio of 1:1.3-1:1.55 on the water-facing surface;

[0046] Preferably, the lifting assembly of the rear wheel mechanism described in step 4 cooperates with the spring to drive the sleeve assembly to move vertically through the cylinder, thereby compensating for the change in the inclination angle of the equipment caused by the uneven ground in real time and keeping the horizontal error of the molding bin less than ±3mm.

[0047] Preferably, the maintenance described in step five includes replacing the agitator faucet and baffle that are worn beyond the limit, and repairing the spiral blade circumference to a diameter of 268 mm using D707 surfacing welding with a tolerance range of 0 to -2 mm.

[0048] Preferably, the maximum particle size of the coarse aggregate of the concrete mixture does not exceed 2 cm, the water-cement ratio is controlled at 1:1.31-1:1.45, and the amount of accelerator added is 4%-6% of the amount of cement.

[0050] Through the frame integrated molding chamber, power chamber, auger chamber and other core modules, the continuous operation of concrete transportation, extrusion molding and quick-setting agent spraying is realized, the process switching time is reduced, and the work efficiency is greatly improved. At the same time, the present invention relies on the reaction force generated by the auger to drive the device to move, and the travel speed can be controlled according to the feed speed, so that the side wall extruder moves along the driving direction, stops the supply of the mixing material, and the side wall extruder stops driving immediately, resumes the supply, and restarts driving;

[0051] The rear wheel lifting assembly (cylinder driven) works in conjunction with the spring buffer system to dynamically adjust the height of the equipment from the ground and absorb ground impact to maintain the stability of the molding chamber operation;

[0052] The air pressure driven quick setting agent spraying system realizes constant pressure spraying through oil-water separation, pressure regulating valve and pressure gauge, avoiding the problem of easy clogging of traditional pumping and ensuring uniform atomization.
