Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and in particular to a reservoir hazard removal and reinforcement system and a construction method. Background Art

[0002] As the core structure for reservoir hazard removal and reinforcement, flood walls are subject to complex effects such as water pressure, temperature changes, and geological subsidence for a long time, and are prone to problems such as structural deformation, surface weathering, and crack expansion. Traditional flood wall repair technologies mostly use single methods such as concrete filling and crack grouting. However, when faced with problems such as expansion joint leakage and incomplete repair of deep cracks, it is often difficult to take into account both dynamic deformation adaptability and deep structural repair effects, resulting in insufficient durability of the repaired wall and easy safety hazards due to secondary cracking.

[0003] The existing flood wall crack repair process usually adopts a uniform drilling depth grouting method, which does not distinguish between through cracks and shallow cracks. This results in insufficient penetration of shallow hole grouting materials and low filling density of deep holes. After repair, there are still voids or unbonded areas inside the cracks, making it difficult to completely restore the integrity and anti-seepage performance of the wall. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a reservoir hazard removal and reinforcement system and construction method, which solves the problem of insufficient grouting due to failure to distinguish the depth of cracks, the existence of voids or bonding defects inside after repair, and the weakening of the integrity and impermeability of the wall.

[0008] Through the above technical solution: the hemp fiber layer is elastically filled with a mixture of asphalt and hemp fiber to adapt to the expansion and contraction of the flood wall, and the sealing layer uses asphalt paste to seal the expansion joint to prevent leakage and reduce secondary cracking caused by thermal expansion and contraction.

[0009] Preferably, the repaired honeycomb surface includes through-filling holes, which are drilled along the cracks with an electric drill, and the through-filling holes are in a state of drilling through the cracks on the flood control wall.

[0010] Through the above technical solution: through-filling holes, drilling through the cracks and then grouting, the deep cracks can be completely filled and the water seepage path can be blocked.

[0011] Preferably, the repaired honeycomb surface includes a non-through filling hole, and the non-through filling hole is a shallow hole punched in the crack on the flood control wall.

[0012] Through the above technical solution: non-through filling holes, drilling holes for shallow cracks can avoid excessive damage to the wall structure and improve the slurry penetration efficiency.

[0013] Preferably, the track mechanism includes two sliding tracks, and the surfaces of the two sliding tracks are slidably connected to sliding sleeves. One side of the two sliding sleeves is provided with a penetrating threaded hole, and the threaded holes are threaded with limiting screws. The bottom of one side of the two sliding sleeves is fixedly connected to a tension ring, and a connecting plate is rotatably connected between the two sliding sleeves.

[0014] Through the above technical solution: the sliding track and the sliding sleeve cooperate to realize the vertical positioning of the grouting mechanism, limit the fixing position of the screw to prevent deviation, and the hinged design of the connecting plate adapts to the uneven wall surface, thereby improving the stability and coverage of the grouting operation.

[0015] Preferably, the grouting mechanism includes a screw pump, the material port input end of the screw pump is fixedly connected to a material storage barrel, the material port output end of the screw pump is fixedly connected to a slurry discharge head, the tube surface of the slurry discharge head is fixedly connected to a connecting block, both sides of the connecting block are fixedly connected to pressing handles, and the surfaces of the two pressing handles are both clipped with tension springs.

[0016] Through the above technical solution: the screw pump provides controllable grouting pressure, the grouting head reduces leakage through the rubber sealing ring, the tension spring and the pressing handle adjust the fitting pressure, reducing the intensity of manual operation and improving the grouting density.

[0017] Preferably, the thickness of the cement mortar layer is 1.5 to 2.5 cm, and an interface agent is pre-sprayed on the base surface before the epoxy mortar is applied. The interface agent is a slurry of epoxy resin and cement mixed in a ratio of 1:1.

[0018] Through the above technical solution: the interface agent is pre-sprayed to form a transition layer, which reduces the shrinkage stress after the epoxy mortar is applied and improves the coating uniformity and long-term adhesion.

[0019] Preferably, the connecting plate and the sliding sleeve are connected via a hinge shaft, the axial direction of the hinge shaft is perpendicular to the extension direction of the sliding track, and a hook is provided at the bottom of the connecting plate for fixing the steel cable.

[0020] Through the above technical solution: the articulated shaft design allows the connecting plate to fine-tune the angle according to the wall slope, and the hook-fixed steel cable ensures the balance of the grouting mechanism during the lowering process, avoiding grouting deviation caused by equipment tilt.

[0021] A reservoir hazard removal and reinforcement construction method, the construction method comprising the following steps: First, the exposed areas of weathered aggregate on the surface of the flood wall are roughened. An electric rotary hammer drill is used to remove 3-5 cm thick concrete to form a repair honeycomb surface. Through-holes or non-through-holes are drilled in the cracks on the repair honeycomb surface. Then, a high-pressure water gun is used to rinse the roughened base surface to ensure that the base surface is moist and free of water accumulation. Install the track mechanism, lay the sliding track vertically downward along the top of the flood wall and close to the wall surface, insert the sliding sleeve into the track and connect it to the connecting plate through the steel cable, lower it to the target position, and tighten the limit screw to fix the grouting mechanism; Start the screw pump of the grouting mechanism and inject the modified epoxy resin cement slurry in the storage barrel into the through filling hole or non-through filling hole through the grouting head. Use the pressing handle and tension spring to assist the worker in the grouting work and reduce the outward pressure during grouting until the slurry fills the cracks. Pour C30 fine stone concrete on the base surface of the honeycomb surface for repair and smooth it. Apply two layers of epoxy mortar after initial setting to ensure uniform coating without any missing coating. For areas without obvious weathering, directly high-pressure clean them and then apply epoxy mortar. Repair the expansion joints on the water-facing side of the flood wall, remove the original cracked asphalt grease sealing layer and the failed hemp layer, refill with a hemp layer mixed with asphalt and hemp, and seal both sides with asphalt grease to form a new sealing layer; Finally, the grouting density and coating integrity were checked, and the repaired area was subjected to 7 days of wet curing to ensure the structural stability of the flood wall.

[0022] Through the above technical solution: the roughening depth of 3~5cm increases the roughness of the base surface, high-pressure washing removes loose particles, provides a clean bonding surface for concrete repair, differentiated drilling matches the crack depth, optimizes the slurry filling path, vertical laying of the sliding track ensures the accurate movement trajectory of the grouting mechanism, and the steel cable controls the lowering speed to avoid equipment shaking, thereby improving the efficiency of grouting point positioning. Modified epoxy resin cement slurry is injected into the filling hole through pressure, and the tension spring buffers the reaction force to reduce slurry overflow and ensure that the cracks are fully filled. C30 fine stone concrete fills the deep roughening area, and epoxy mortar covers the surface micro-cracks to form a composite protective layer to improve the anti-seepage and anti-scouring properties. After removing the failed filler, the hemp fiber layer is refilled. The asphalt grease sealing layer restores the dynamic sealing of the expansion joint and extends the service life. The non-woven fabric covering combined with water mist spraying maintains the humidity of the base surface. Temperature-controlled maintenance reduces shrinkage and cracking. The 7-day maintenance cycle ensures the stable development of the strength of the repair material.

[0023] Preferably, during the wet curing period, the repair area is covered with non-woven fabric, sprayed with water mist 3 to 4 times a day, the curing temperature is controlled at 15 to 30° C., and no external load is applied to the repair area within 7 days.

[0024] The above technical solution involves covering the repair area with non-woven fabric and applying a daily mist spray to maintain a constant moist surface, reducing shrinkage cracks caused by rapid evaporation. Curing temperatures are controlled between 15°C and 30°C to avoid high temperatures that accelerate water loss or low temperatures that delay curing, thereby optimizing cement hydration reaction conditions. Furthermore, external loads are prohibited within the repair area for seven days to prevent structural damage to the incompletely hardened repair layer due to external compression or vibration. This ensures the stable development of the repair material's strength and improves the durability and overall density of the protective coating.

[0025] The present invention provides a reservoir hazard removal and reinforcement system and construction method. It has the following beneficial effects: 1. In the present invention, the sliding track of the track mechanism is linked with the sliding sleeve to move the grouting mechanism vertically along the surface of the flood wall. The tension spring and the pressing handle are used to adjust the fitting pressure of the grouting head to achieve the continuity and controllability of the grouting process, avoid manual positioning deviation, and reduce the waste of grouting materials. The pressure injection of the screw pump ensures that the slurry is evenly filled in the through filling holes and non-through filling holes to avoid voids or leakage, thereby improving the coverage and density of crack repair, shortening the construction period and reducing the rework rate.

[0026] 2. In the present invention, the elastic filling of the hemp fiber layer and the sealing layer in the telescopic mechanism can adapt to the expansion and contraction deformation of the flood wall caused by temperature or load changes, thereby reducing the risk of secondary cracking. At the same time, the differentiated drilling design of the through filling holes and the non-through filling holes in the honeycomb surface is repaired, and grouting is performed according to the depth of the cracks, so that the modified epoxy resin cement slurry can fully penetrate the interior of the cracks, repair deep and shallow defects, strengthen the dynamic sealing of the expansion joint, and at the same time improve the repair effect of the wall cracks, thereby achieving long-term stability of the overall structure of the flood wall in a complex environment.

[0027] 3. In the present invention, C30 fine stone concrete is poured in layers on the base surface of the repaired honeycomb surface and epoxy mortar is applied, combined with non-woven fabric covering and temperature-controlled maintenance to form a gradient protection structure. Fine stone concrete fills the deep roughened area, epoxy mortar covers the surface micro-cracks, and the interface agent strengthens the adhesion between new and old materials. During the moist maintenance, water mist is sprayed to maintain the humidity of the base surface to avoid shrinkage and cracking. By combining physical filling with chemical protection, the anti-scouring and anti-seepage properties of the water-facing surface of the flood wall are improved, the service life of the cement mortar layer and the repaired area is extended, and the periodic maintenance cost is reduced.
