Description

Technical Field

[0001] The present application relates to the technical field, and in particular to a method for constructing a landscape bridge using reinforced concrete and ceramic particles and a bridge deck structure thereof. Background Art

[0002] With the development of science and technology, new materials are constantly emerging, and people have higher requirements for the landscape effects and walking texture of park slow-moving system paving, landscape bridge paving, square paving, etc. The landscape effects and walking texture of urban landscape bridges and park slow-moving system surface paving have also become the focus of users.

[0003] Traditional landscape bridge deck pavements are mainly divided into wood, asphalt, plastic, concrete, etc. There are various problems in terms of applicability, durability, safety, economy, environmental protection, aesthetics, and easy maintenance.

[0004] The various types of problems are: the wooden panels of outdoor landscape bridges are naturally beautiful, but because the bridge deck is only paved with wooden boards, the wooden boards themselves are prone to water absorption and expansion, water loss and cracking. When used in outdoor environments, they are prone to deformation, cracking, and even warping after being exposed to wind, rain, and sun for a long time. In addition, microorganisms are prone to grow under the wooden boards after being exposed to moisture for a long time, resulting in an uneven bridge deck, a reduced walking texture, and increased maintenance costs.

[0005] Although the outdoor asphalt bridge deck paving technology is mature and the quality is reliable, asphalt paving requires special machinery for transportation, paving and compaction. The wetland landscape bridge is a pedestrian bridge in the forest, and its bearing capacity and machinery operation space do not meet the construction requirements.

[0006] Plastic bridge deck pavements have good elasticity, a wide variety of types, and bright colors. The weather-resistant materials are expensive and difficult to repair after damage. The quality of low-priced polymer materials is unstable. The materials are easily oxidized and faded when exposed to the open air for a long time. The edges of the positive corners are weak and easily damaged. After local repairs, the overall color difference of the bridge deck is large.

[0007] Concrete bridge deck paving is cheap and of reliable quality, but the aesthetics of the bridge deck paving used for wetland landscape bridges is difficult to guarantee. The overall appearance is rigid and low-grade, and the construction time is long. It has poor water dispersion and is prone to freezing on rainy days in winter, and pedestrians are prone to slipping when walking, resulting in a poor overall landscape effect.

[0008] The above problems lead to technical problems such as slow paving speed of existing landscape bridges, poor landscape effect of the landscape bridge pavement layer and poor walking texture. Summary of the invention

[0009] The present application provides a construction method of a landscape bridge made of a combination of reinforced concrete and ceramic particles and a bridge deck structure thereof, which are used to solve the technical problems existing in the prior art, such as high cost, large restrictions on the operating environment for paving equipment, lack of aesthetics, poor environmental coordination, poor walking texture, and difficulty in maintenance and repair of cracked and damaged bridge decks.

[0010] The present application provides a method for constructing a landscape bridge with reinforced concrete and ceramic particles, comprising the following steps:

[0011] Step S20: Draw lines along the longitudinal and transverse directions of the steel box girder according to the design drawings to divide the top surface of the steel box girder into multiple grids, each grid having a size of 250 mm x 250 mm, and weld shear studs with a diameter of φ13 mm and a length of 80 mm at the intersection of each grid;

[0012] Step S30: Arrange a plurality of precast concrete pads in a plum blossom shape on the bridge deck, the precast concrete pads are accommodated in the gaps between adjacent shear nails, the horizontal and vertical spacings between any two pads are 500 mm, and the precast concrete pads are arranged on the top surface of the steel box girder and under the steel mesh;

[0013] Setting up the precast concrete pads in this way can ensure that the protective layer of the distributed steel bars meets the requirements and plays the role of padding the steel bars.

[0014] Step S40: Fully install φ12 steel mesh on the top surface of the precast concrete pad at a spacing of 100x100mm along the longitudinal and transverse directions of the bridge deck, and adjust the position where the mesh conflicts with the bolts to the left and right;

[0015] Step S50: pouring concrete to form a concrete layer, the concrete covers the top surface of the bridge deck steel box girder, the shear nails and the steel mesh are contained in the concrete layer, the poured concrete is cured, trimmed and polished, and the polished top surface of the concrete layer is cleaned;

[0016] Step S60: fully spread the glass fiber anti-cracking mesh on the top surface of the concrete layer, and the overlapping length of the glass fiber anti-cracking mesh in the longitudinal and transverse directions is 70 to 100 mm;

[0017] Following these steps can ensure that the fiberglass anti-cracking mesh is laid smoothly and firmly, and provide reliable support for subsequent stacking layers.

[0018] Step S70: Use a scraping tool to evenly apply the mixed PUNM polyurethane adhesive on the glass fiber anti-cracking net, and scrape 4.5 kg of PUNM polyurethane adhesive per square meter as a sealing bottom layer, and the average thickness of the obtained sealing bottom layer is controlled to be 2.5-3.5 mm;

[0019] Applying at this thickness can ensure the reliability of the adhesion between the sealant and the fiberglass mesh, and achieve sealing and waterproofing of the bottom layer.

[0020] Step S80: before the adhesive on the sealing bottom layer is completely dry, ceramic particles are evenly spread on the top surface of the sealing bottom layer, and 1.5-2.0 kg of ceramic particles are evenly spread per square meter to obtain a base ceramic particle layer;

[0021] Setting the ceramic particle layer according to the above conditions can help utilize the greater roughness of the ceramic particle layer to achieve effective bonding between the sealing bottom layer under the ceramic particle layer and the upper layer, while retaining the water seepage and drainage capabilities to avoid water accumulation on the bridge surface.

[0022] Step S90: Mix black ceramic particles: dark gray ceramic particles: light gray ceramic particles in a mass ratio of 6:3:1, add two-component glue, and stir until uniform to obtain mixed-color ceramic particles. After the base ceramic particle layer has the construction strength, the mixed-color ceramic particles are transported to the paving point, spread, leveled with a ruler, compacted with a spatula to obtain a surface ceramic particle layer, lay a polyurethane layer on the surface ceramic particle layer, cover the bridge deck, and complete the construction.

[0023] By setting PUNM polyurethane adhesive and glass fiber anti-cracking net, on the one hand, it can effectively prevent rainwater from seeping in and causing steel beams to rust, and on the other hand, it can prevent concrete alkali from causing the surface ceramic particles to become spotted and have color differences, effectively maintaining the color of the bridge deck to meet landscape needs; by setting a surface ceramic particle layer on the bridge deck and calcining it at high temperature, the color is stable, it is anti-slip and wear-resistant, the mixture has good fluidity, and the edges and joints are rounded; the overlay treatment enhances the adhesion of the surface particles, effectively avoiding local sanding.

[0024] The bridge deck structure constructed by this method has a surface ceramic particle layer with good wear resistance and can maintain the construction effect for a long time, meeting the viewing needs of landscape bridges.

[0025] Preferably, step S40 includes: step S41: after the steel mesh is tied, the tied mesh is inspected for quality and then washed with a high-pressure water gun to remove debris on the bridge deck, which can reduce the amount of debris on the bridge deck during subsequent construction and improve engineering reliability.

[0026] Preferably, step S50 includes: step S51: when pouring concrete, use a handheld light vibrator to vibrate and compact it, and smooth the surface of the solidified concrete. After the concrete has finally set, cover the concrete surface with a geotextile and sprinkle water on time for maintenance.

[0027] Preferably, step S50 includes: step S52: after the curing is completed, the local protrusions of the concrete layer and the hardened concrete on both sides of the edge steel plate are polished with an angle grinder and a wire brush, and then cleaned with a broom. This can provide a flat and smooth surface for subsequent construction, which is conducive to improving the force bearing capacity of the subsequent surface.

[0028] Preferably, step S50 includes: step S53: cleaning the concrete surface: thoroughly washing the bridge deck with a high-pressure water gun, drying it in the sun, and blowing away fine dust again with a hair dryer. Reducing the amount of impurities on the top surface of the concrete layer can improve the bonding reliability of the subsequent stacked layers and the concrete layer.

[0029] Preferably, the coating tool in step S70 is a scraper or a scraper.

[0030] Preferably, step S90 includes: performing edge finishing on the surface ceramic particle layer, and prohibiting the bridge deck from being stepped on after being exposed to rain within 24 hours after the surface ceramic particle layer is constructed, so as to protect the various layers of the bridge deck structure and avoid dislocation.

[0031] Preferably, the method comprises: Step S10: after the welding of the steel box beam of the bridge deck is completed and the quality inspection is passed, the sundries on the bridge deck are cleaned to reduce the sundries and improve the connection reliability between the subsequent layers and the steel box beam of the bridge deck.

[0032] Preferably, the ceramic particles have a diameter of 1 to 2 mm.

[0033] Another aspect of the present application also provides a landscape bridge deck composed of a reinforced concrete base layer and a ceramic particle surface layer, comprising:

[0034] A shear nail layer is set on the top surface of the steel box girder of the landscape bridge;

[0035] A single steel mesh layer disposed on the top surface of the precast concrete pad;

[0036] A poured concrete layer covering the shear nail layer and the steel mesh layer;

[0037] A glass fiber anti-cracking mesh layer disposed on the top surface of the concrete layer;

[0038] A PUNM polyurethane adhesive layer disposed on the top surface of the glass fiber anti-cracking mesh layer;

[0039] A base ceramic particle layer disposed on a PUNM polyurethane adhesive layer;

[0040] A surface ceramic particle layer disposed on the top surface of the base ceramic particle layer;

[0041] It comprises: a plurality of precast concrete pads, which are arranged in a plum blossom shape and accommodated between the shear nails of the bridge deck.

[0042] By setting PUNM polyurethane adhesive and glass fiber anti-cracking net between the concrete layer and the base ceramic particle layer, it can effectively prevent the surface ceramic particles from becoming spotted and having color differences due to alkali efflux in the concrete. The various colors of the surface ceramic particle layer can be used to increase the ornamental value of the landscape bridge.
