Construction steps of the diversion screen foundation, the beam, the column and the sealing plate are as follows: the lower structure of the flow guide screen 1 is divided into a foundation, a beam 3, a column and a sealing plate; the construction is divided into two times, the diversion screen foundation 2 is constructed firstly, namely the diversion screen foundation 2 is installed at the position where the diversion screen 1 is installed in advance, so that the upper surface of the diversion screen foundation 2 is equal to the surface of an anti-blowing platform of an airport, the diversion screen foundation 2 needs to be measured and paid off in the construction, a total station needs to be used for releasing a start point and a stop point in the major axis direction during the measurement and paying off, a steel tape can be used for branching in the minor axis direction, and the distance of an expansion joint is reserved every 18 meters during the branching;
then, a beam 3 is installed on the diversion screen foundation 2, a windward upright post 4 and a leeward upright post 5 are installed on two sides of the beam 3, and a sealing plate is installed in the windward upright post 4;
the construction process of the diversion screen foundation, the diversion screen beam, the diversion screen column and the diversion screen sealing plate comprises the steps of steel bar binding, formwork erecting and concrete pouring. Wherein, the reinforcement bar binding needs to ensure that the reinforcement bar is free of corrosion and is firmly bound, and the type, the interval and the thickness of the protective layer of the reinforcement bar meet the design requirements. And the construction of the diversion screen foundation and the diversion screen beams, columns and sealing plates adopts the wood formwork as a construction template, and the wood formwork has light weight and low cost, so that the construction cost of the diversion screen foundation, the beams, the columns and the sealing plates in the earlier stage can be reduced. And then, the surface of the template is required to be smooth, the positioning is accurate and firm, the size meets the requirements of design drawings, and sundries in the wood mould are required to be cleaned before the wood mould is closed. The bottom gap of the template is blocked by mortar before concrete pouring, so that the condition of slurry leakage is avoided to a certain extent; during pouring, the slump of concrete needs to be noticed, and the slump is controlled to be 12 cm; the concrete needs to be vibrated and compacted to avoid the occurrence of a honeycomb pitted surface. When concrete foundation corners cannot be damaged due to form removal, the form removal is needed, and after the form removal, geotextile sprinkling wet curing is adopted in time.

The support column 11 is the same as the prefabrication process of the windward sloping plate 12, and is formed by bottom die installation, side die installation, reinforcement embedded part welding, sloping die installation, concrete pouring and form removal maintenance, and the prefabrication process specifically comprises the following steps:
1. bottom die and side die installation: before the bottom die is installed, a flat prefabricated site needs to be established according to the number of the templates, and the site is hardened by concrete. Drilling 3-5 holes on the periphery of the steel die by using electric drills according to the distribution positions of the shaped steel die, driving short steel bar joints into the holes, enabling the steel bars to protrude out of the ground by about 10cm, welding the short steel bar joints with the bottom die, fixing the bottom die, and preventing the bottom die from being pulled up during horizontal displacement and demoulding of the steel die. The bottom die is installed by the leveling instrument, so that the prefabricated part is prevented from being distorted due to unevenness of the template, and the prefabricated part is not matched with the beam 3-column embedded part in position and is distorted linearly during installation. And after the bottom die is fixed, filling the hollow part of the bottom die with concrete, and wrapping and reinforcing the periphery of the bottom die. After the bottom die is finished, the side die can be installed, the side die can be directly assembled according to the corresponding position, a piece of double-sided adhesive tape needs to be adhered to the bottom of the side die for preventing slurry leakage, and finally the next procedure can be carried out by coating a release agent;
2. binding steel bars and welding embedded parts: in order to avoid influence on construction progress caused by steel bar binding and embedded part welding to a certain extent, the embedded parts need to be bound, formed and welded on the steel bar net sheets in advance, the steel bar net sheets can be manufactured on redundant templates, and the steel bar net sheets, the embedded parts and the templates are ensured to be matched; the manufactured steel mesh is placed on one side for standby by adopting a mode of arranging the lower cover on the upper cover. And (3) directly putting the prefabricated part in place after the prefabricated part is removed from the bottom die and the side die and the demolding agent is coated, wherein the binding of the reinforcing steel bars and the thickness of the protective layer need to meet the requirements of drawings and design. The phenomena of binding leakage, rib leakage, insufficient lapping length of the reinforcing steel bars, insufficient angle of hook bending of the stirrups and corrosion of the reinforcing steel bars cannot occur;
3. installing an inclined die: after the reinforcing mesh and the embedded part are in place, installing an inclined die, coating a release agent on the inclined die, assembling the inclined die according to the corresponding position, adhering a double-sided adhesive tape at the bottom of the inclined die in order to prevent slurry leakage, re-screwing the bolt after the assembly of all side dies is completed, and ensuring that the integrity of the template meets the requirement;
4. pouring concrete: self-stirring by adopting a stirrer. Because the thickness of the support column 11 is thinner, fine stone concrete is adopted for pouring, after a proper amount of concrete is put in, the concrete is vibrated by an inserted vibrating spear of ZN35, and the vibration of the concrete is stopped when the concrete is not turned over and bubbles. The excess concrete is removed by square steel, and then the concrete is ground by a sand plate and covered by a film. Manufacturing a sunshade under the condition of direct solar radiation; after standing for 10 minutes, the concrete is collected for three times continuously. It is noted that trowels are a common tool used by workers to plaster mortar, also known as spatulas. The concrete surface is repeatedly pressed and smeared on the concrete surface by using an iron trowel, a wood trowel or an aluminum alloy scraper until the surface required by the engineering is smooth and clean;
5. and (5) maintenance: and covering the thin film after finishing the surface collection for initial maintenance, and removing the thin film and covering the non-woven geotextile for watering maintenance when the member concrete does not stick to the geotextile. And when the strength of the concrete member reaches 75% of the designed strength, the concrete member is lifted to a member storage site to be maintained continuously, and finally, a mold is vacated for manufacturing the members in the next batch.
