S4, when the binding of the batter post and the batter wall steel bar in the step S2 or the setting of the template in the step S3 are carried out, the step S2 and the step S3 need to be subjected to cross construction according to the set construction sequence;
The construction sequence is as follows:
(1) at the installation position of the formwork 4, the installation mode of installing and reinforcing the inclined columns, the wall formwork 4 and the scaffold 15 supporting platform in the step S3 is applied, the formwork 4 and the peripheral support are preliminarily erected for pouring the reinforced concrete pile 2, and as shown in fig. 3, the root position and the angle of the steel bar 1 are adjusted while the reinforced concrete pile 2 is poured.

s5, checking and accepting a support system: checking and accepting the support system formed by the templates, and making a check and acceptance record;
S6, steel bar acceptance step: checking whether the steel bars meet the requirements according to the design drawing and safety precautions;
The method specifically comprises the following five steps:
s601, checking whether the steel number, the diameter, the number and the spacing of the steel bars are correct according to a design drawing.
S602, checking whether the position of the negative rib meets the regulation.
S603, checking the position and the lap joint length of the steel bar joint to determine whether the positions and the lap joint length meet the requirements.
S604, checking whether the thickness of the steel bar protection layer meets the requirement.
and S605, checking whether the steel bars are firmly bound or not and whether the steel bars are loosened or not.
S606, checking whether the steel bars are clean or not.
s7, pouring concrete: in the concrete pouring process, the sinking of the top end of the batter post and the deformation of the template are observed, construction management is reasonably carried out according to the observation condition, and the concrete is subjected to defoaming treatment through the vibrating rod; and after pouring is finished, covering the top surface template on the top surface of the inclined column.
the defoaming treatment in concrete construction specifically comprises the following steps:
S701, before concrete is poured, inserting a hard rubber pipe 5 with the diameter of about 150mm into the inclined column, as shown in fig. 8, forming a groove 6 on the surface of the rubber pipe, wherein the width of the groove is 100mm, and then placing a vibrating rod 7 in the groove 6.
s702, selecting a vibrating rod with the action radius of 70mm, and inserting the vibrating rod and the hard rubber tube 5 into the inclined column steel bar before pouring concrete. The position of the vibrating rod is controlled during vibration, so that the vibrating rod is always in the rubber tube. And the rubber tube is used as a string tube, base mortar and bottom concrete are conveyed downwards, the vibrating rod and the rubber tube are lifted along with the pouring of the concrete, and each inclined column vibrates once.
the space between the diagonal column stirrups is small, and the bottom surface (lower surface) of the diagonal column is an inclined surface. Thus, some of the mortar in the mix is very easily hindered by the stirrups during the downward delivery of the concrete. When concrete is delivered down to a designated location, there is a high probability of a lack of mortar.
and the inclined column has relatively large inclination, and the arrangement of the reinforcing steel bars is very tight, so that the work of the vibrating rod is limited to a certain extent, and the vibrating rod is difficult to reach the bottom of the inclined column. Since during its lifting the stirrup may jam the tamper and there is no chance of reinserting the rod at all. In the step S702, the concrete can be dredged by improving the vibrating rod, so that the problem that the mortar and the bottom concrete of the base bottom are difficult to reach the bottom of the batter post is solved, and the vibrating rod can be prevented from being clamped by the stirrup and the reinforcing steel bar and cannot work normally.
S703, strictly controlling the slump and the expansion of the concrete mixture, pouring 4 batter posts as a test before large-area construction of batter post concrete on site, fully referencing the test result, and summarizing the slump and the expansion of the concrete mixture. According to the summarized results, slump was controlled to be in the range of 210mm to 230mm, and the degree of expansion was in the range of 370mm to 450 mm. When large-area construction is carried out, the slump and the expansion degree are detected before each batter post is poured by taking the slump and the expansion degree as corresponding control bases, and the concrete which meets the requirements is allowed to be poured.
the arrangement of the step S703 can ensure that the appearance and the quality of the poured batter post meet the preset requirements.
and S704, opening air grooves at intervals of 2m on the inclined column top surface template. In general, the height of the air duct is set to 30mm, the width thereof is required to be about 200mm, and the fine steel wire mesh is lined therein. In the process of pouring the inclined column concrete, the top surface formwork is lightly vibrated by a 50mm vibrating rod, and meanwhile, bubbles in the vent grooves are observed, so that the bubbles are discharged from the vent grooves.
The batter post is in the in-process of vibrating, and the produced bubble of concrete is outwards discharged the degree of difficulty great, and when these bubbles slowly accumulate the gathering to under the template attached to the batter post top surface, will cause very big influence to the effect of construction, lead to top surface concrete to appear quality problems such as honeycomb, pitted skin, and step S704 is improved the setting of the stick that shakes, can avoid the production of above-mentioned phenomenon.
S8, template removal: and after the strength of the concrete reaches the preset strength of 1.2Mpa, dismantling the scaffold, the peripheral support frame and the template. When the formwork is removed, the formwork on the top surface and the side surface of the batter post is removed, but the formwork on the lower surface of the batter post cannot be removed, such as the formwork at the position shown by the formwork 4 in fig. 7, and the removal of the integral support is forbidden. And after the whole is stabilized, the template and the whole support on the lower surface of the batter post are removed simultaneously, and the whole support comprises a peripheral support frame and a scaffold.
