[0013] Step 1: The feeding mechanism moves so that different raw materials enter through the injection pipe, the flow valve controls the amount entering the mixing drum, the mixing motor is started, the mixing shaft is driven to rotate, and the mixing grid is driven to rotate, so as to achieve mixing of the mixed fiber concrete, and after mixing, the material is fed, the control valve is opened, and the mixed concrete enters the diverter box, the extraction pump is started, the concrete in the diverter box is extracted, and enters the pouring nozzle through the delivery pipe;

[0014] Step 2: The motion mechanism moves, the motion motor is started, thereby driving the motion gear to rotate, thereby driving the motion plate to move, thereby driving the device to move near the reinforced masonry;

[0015] Step 3: The drilling assembly moves, so that the drilling electric screw rotates, thereby driving the drilling movable frame to move toward the masonry, starting the drilling motor, thereby driving the drill bit to rotate and enter the masonry, thereby achieving drilling on the masonry, and during drilling, multiple holes are drilled at the same time, thereby achieving drilling on the masonry;

[0016] Step 4: After the drilling is completed, the concrete pouring mechanism moves, the pouring nozzle on the upper side is turned on, and the pouring motor is started, thereby driving the pouring nozzle to reciprocate and pour the first layer of mixed fiber concrete;

[0017] Step 5: After the first layer of hybrid fiber concrete is poured, the grid laying mechanism moves, and the initial segment of the grid is fixed at the beginning. When the rectangular frame moves upward, the mounting block is driven to move upward, thereby driving the fiber grid to move and lay on the first layer of poured concrete. After laying to the corresponding position, the shearing electric screw rotates, driving the shearing knife to move, thereby cutting the fiber grid, thereby laying the grid on the first layer of hybrid fiber concrete;

[0018] Step 6: The fixing assembly moves. After the connecting pipe moves to the corresponding position of the drill hole, the fixing electric push rod moves, thereby pushing the insulation nail to move.

[0019] Step 7: After the fixing is completed, the concrete pouring mechanism moves, the pouring nozzle on the lower side is opened, and the pouring motor is started, thereby driving the pouring nozzle to reciprocate and pour the second layer of mixed fiber concrete;

[0020] Step 8: During the entire movement process, the lifting mechanism moves to adjust the height of the reinforcement.

[0021] Preferably, the raw materials of the mixed fiber concrete in step one include cement, silica fume, fly ash, river sand, and three kinds of fibers: calcium carbonate whisker, basalt fiber, and PVA, and the ratio of cement: silica fume: fly ash: river sand: water: calcium carbonate whisker: basalt fiber: PVA is 1: 0.081: 0.270: 0.541: 0.405: 0.026: 0.021: 0.009.

[0022] Preferably, the masonry in step 2 further comprises: reserving mortar joints in the masonry construction.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention provides a device for reinforcing brickwork with grid-reinforced hybrid fiber concrete, which can realize drilling holes on the masonry to facilitate grid fixation, and can realize pouring of concrete, can realize scraping and leveling after pouring, and can realize laying and fixing of the grid, and pouring of concrete after fixation.

[0025] 2. The present invention combines the dual reinforcement effects of fiber grid and mixed fiber concrete and is used to reinforce brick masonry walls with significant effects.

[0026] 3. The advantage of the hybrid fiber concrete mix ratio in the present invention is that it utilizes the advantage of calcium carbonate whiskers as chopped fibers to reduce the dosage of PVA, thereby reducing the construction cost without reducing the strength. The use of fiber woven mesh solves the problem of closed bubbles in fiber cloth. In addition, it has good moisture permeability and is well coordinated with the hybrid fiber concrete matrix.

[0027] 4. The hybrid fiber concrete in the present invention has the properties of high strength, high ductility, high durability, etc. After being used for surface layer reinforcement, it can effectively improve the bearing capacity of brick masonry walls, improve their seismic performance, and extend the service life of the structure. It can be used for daily reinforcement and repair of brick masonry walls.

[0028] 5. The hybrid fiber concrete matrix used in the present invention has good bonding performance with the brick masonry wall, and the fiber grid and the hybrid fiber concrete matrix also have good bonding performance. Under the double reinforcement mode, this new reinforcement method effectively inhibits the development of shear cracks, improves the shear strength of the brick masonry wall, and greatly improves the deformation capacity of the brick masonry wall itself, thereby significantly improving the integrity and seismic performance of the brick masonry wall. At the same time, PVA fiber is relatively expensive. The calcium carbonate whisker in the present invention can be regarded as short-cut fiber, and the cost is very low. It can replace part of the PVA fiber and reduce the amount of PVA fiber. Adding silica fume to the hybrid fiber concrete can improve the strength while reducing the amount of cement.

[0070] (1) This research group used experiments to verify the seismic effect of fiber braided mesh reinforced hybrid fiber concrete reinforced brick masonry walls. The test data are detailed in Table 1.

[0071] Table 1 Comparison of seismic performance parameters of masonry walls

[0072] serial number Peak load / kN Destruction load / kN Ductility coefficient Cumulative energy consumption / kN∙mm M-0 380 323 1.59 26070 FM-0-1 491 417.35 8.25 50945 FM-B-1 496 421.6 5.35 68839 FM-C-1 518 440.3 4.85 58618

[0073] Analysis of the data in Table 1 shows that compared with the unreinforced specimens, after the brick masonry wall was reinforced with hybrid fiber surface layer (FM-0-1), basalt fiber woven mesh reinforced hybrid fiber concrete (FM-B-1), and carbon fiber woven mesh reinforced hybrid fiber concrete (FM-C-1), the bearing capacity of specimens FM-0-1, FM-B-1, and FM-C-1 increased by 29.2%, 30.5%, and 36.3%, respectively, and the ductility index increased by 419%, 236%, and 205%, respectively, and the cumulative energy consumption increased by 95.4%, 164%, and 124.8%, respectively, indicating that after the fiber woven mesh reinforced hybrid fiber concrete was reinforced, the bearing capacity and energy consumption capacity were greatly improved, and the method was feasible.

[0079] The appearance of the specimen at different magnifications is shown in the figure above. Fig.21 This is the SEM picture of basalt and PVA. It can be seen in the picture that the crack is deflected or blocked in front of the fiber, which shows that the presence of fiber can effectively inhibit or delay the development of cracks. Fig. 22 This is the microscopic appearance of PVA. The filaments attached to it are calcium carbonate whiskers. Under the microscopic level, calcium carbonate whiskers are attached to PVA and other fibers, filling tiny pores and making the interior of the concrete denser. The calcium carbonate whiskers dispersed in the concrete will have a bridging effect at tiny cracks. The bridging whiskers make the concrete matrix gradually form a whisker network structure, thereby inhibiting the generation of tiny cracks inside the concrete, thereby improving the mechanical properties of the concrete.
