Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering construction, in particular to a soil slope concrete face wall formwork reinforcement component. Background Art

[0002] Among the protective facilities of civil engineering in mountainous areas of my country, concrete facing walls are widely used in civil engineering slope protection, especially slope protection projects, because of their beautiful appearance and reliable quality. However, due to the lack of reliable fixings for the concrete facing wall formwork on soil slopes, the formwork is prone to deformation, causing economic losses. The facing wall formwork generally adopts top pressure reinforcement measures, which is labor-intensive and time-consuming, and is prone to expansion and deformation; if the facing wall formwork adopts steel bar anchor rods as qualitative fixings, this method increases construction costs and is expensive. Therefore, the application of a reinforcement component for the concrete facing wall formwork on soil slopes is imperative. Summary of the invention

[0003] Technical realization elements: The technical problem to be solved by the utility model is to overcome the defects of the existing soil slope concrete facing wall formwork technology, and provide a reinforcement component with simple structure, convenient production, labor saving, local materials, and low cost. The formwork is processed firmly, not easy to deform, easy to operate, easy to check and position, and reliable to use. It solves the problems of difficult fixing of concrete facing walls, labor and labor, deformation of expansion molds, and high construction costs of steel anchors and qualitative fixings. The overall structure of the formwork is easy to install and disassemble, and the reinforcement component has a certain tensile anchoring and stabilizing effect on the facing wall.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a soil slope concrete face wall template reinforcement component, characterized in that the template reinforcement component is composed of 2 ground anchor ribs, 1 wedge-shaped wood and 1 tie rod, and the reinforcement component is made and assembled on site. Holes are drilled in advance on the soil slope and hammered into the reinforcement component to a predetermined depth underground. Expansive cement mortar is injected into the hole to further improve the anchoring force of the component. Grouting is divided into two times. The first time is grouting 1 / 4 of the hole depth before the reinforcement component enters the hole, and the second time is after the reinforcement component is anchored, the expansive cement mortar fills the hole. One end of the tie rod is tied to the ground anchor rib, and the other end fixes the template and the rib. Load transfer direction: reinforced concrete → template → rib → tie rod → reinforcement component. Reinforcement working principle: 1 tie rod is tied to 2 ground anchor ribs at 1 / 3, and the tying method is a double set knot commonly known as a pig's hoof buckle. Before entering the hole, the top of the ground anchor rib is twisted and then located at the center of the hole. The length ensures that both ends of the tie rod extend out of the template to tie the rib. Before entering the hole, the wedge-shaped wood is inserted into the anchor wood 50MM, and the wedge-shaped wood and the anchor edge wood are vertically downward to the bottom of the hole. Under the action of hammering, the wedge-shaped wood is inserted between the two anchor edge woods, and the anchor edge wood moves toward the soil to compact the soil. The volume of the anchor end increases, and the tension bar effectively tightens the two anchor edge woods under the action of the wedge-shaped wood, thereby achieving the anchoring effect to meet the template and edge wood load. Before the concrete solidifies, the reinforcement components limit the displacement of the concrete and the template. After the concrete solidifies, the reinforcement components are closely connected with the retaining wall and bear the force together, effectively improving the bearing capacity and durability of the retaining wall.

[0009] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0010] Material requirements: 1. Reinforcement components: The anchor edge wood specifications are 40MM*80MM and 400MM long, the wedge wood bottom surface is 40MM*80MM and 200MM long, and the anchor edge wood and wedge wood are treated with anti-corrosion. The tension bar is a galvanized iron wire with a diameter of not less than 4MM and a cross-sectional area of ​​12.56MM2. The tensile strength of general iron wire is 30-55Kg / MM2, and the tensile strength is 376.8-690.8Kg. 2. The water-cement ratio of the expansive cement mortar is determined by on-site testing.

[0011] Reinforcement component construction process: measurement and layout → drilling and installation of reinforcement components → installation of formwork → pouring concrete → demoulding and maintenance → modification of concrete surface. 1.

Drill holes and install reinforcement components: use an electric hammer to drill holes, and the drill bit is a soil hole drill bit. The drilling depth is generally not less than 800MM and the drilling diameter is not more than 115MM according to the soil type. After cleaning the hole, tamp the bottom of the hole. Inject 1 / 4 hole depth expansion cement mortar and then install the reinforcement components. Under the action of hammering, the expansion cement mortar further diffuses into the soil to wrap the reinforcement components. After the cement solidifies, the anchoring force is further increased. After the reinforcement components are buried, they are hammered to the predetermined depth with auxiliary steel pipes. The tie rod is located in the middle of the hole. Avoid damaging the tie rod when hammering. After the pull-out test, pour the expansion cement mortar to the ground surface in batches. 3. Install the formwork: Install the formwork support, open a circular hole on the formwork according to the spacing of the reinforcement components, and let the reinforcement pass through the circular hole. After all the reinforcements on the single formwork pass through the circular hole, install the longitudinal ribs from bottom to top. Above the longitudinal ribs are the transverse ribs or steel sections, and the transverse ribs or steel sections are fixed with reinforcements in turn. 5. Pouring concrete: After a batch of formwork is fully installed, pour concrete in layers according to the design and construction plan. 6. Demolding and curing: The formwork can be removed after 24 hours. After demolding, water should be sprinkled in time for curing until the design strength is reached. After demolding, the exposed part of the reinforcement can be cut to modify the concrete surface.
