Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, in the structure for protecting the exposed pipe pile of the basement, the pipe pile 10 penetrates through the basement bottom plate 20, a bearing platform 30 is arranged on the top of the pipe pile 10 and located above the basement bottom plate 20, a section of the pipe pile 10 from the bearing platform 30 to the basement bottom plate 20 is an exposed section, and the exposed section of the pipe pile 10 is covered with a protective layer 40; the protective layer 40 and the basement bottom plate 20 are both of reinforced concrete structures, and the reinforcing steel bars 401 in the protective layer are overlapped with the reinforcing steel bars 201 in the basement bottom plate.
This technical scheme is through setting up the section that exposes of protective layer cladding tubular pile in order to protect the section that exposes of this tubular pile, avoids causing the harm to the section that exposes of tubular pile in the basement construction, and accomplishes the back at the basement, also can play collision avoidance's effect. Through the reinforcing bar overlap joint with the reinforcing bar in the protective layer and the basement bottom plate in order to improve the structural strength of protective layer to improve the protective effect of protective layer.
The rebar in the protective layer 40 includes rebar 402 embedded within the cap.
According to the technical scheme, the firmness of the bonding of the protective layer and the bearing platform can be improved by adopting the bar planting scheme. To further improve the protective effect of the protective layer.
The length of the embedded steel bar 402 embedded in the bearing platform 30 is not less than 15d, wherein d is the diameter of the embedded steel bar 402.
This technical scheme reasonable in design through suitably selecting the length that bar planting reinforcing bar implanted in the cushion cap in order to improve the fastness of protective layer and cushion cap drawing and fixing combination effectively.
As shown in fig. 2, the protective layer 40 has a tubular shape with an inner and outer circular cross section. The technical scheme can increase the section area of the protective layer, improve the bearing capacity of the protective layer and improve the protection effect of the protective layer.
The concrete belonging to the protective layer is divided into a first part 403 and a second part, wherein the first part 403 of the concrete of the protective layer extends downwards from the bearing platform, the upper interface of the first part of the concrete of the protective layer is connected with the bearing platform 30, the lower interface 404 of the first part of the concrete of the protective layer is at a certain distance h from the basement floor to be built, and the second part of the concrete of the protective layer is integrated with the concrete belonging to the basement floor.
In this embodiment, the following may be referred to in the construction process:
before the basement bottom plate is poured, the outer wall of the tubular pile and the bottom wall of the existing bearing platform are cleaned, air-dried and brushed twice by cement paste on the surface. Firstly, building a tubular pile reinforcement cage which covers the exposed section of the tubular pile on the periphery of the exposed section of the tubular pile, wherein the bar-embedded steel bars of the tubular pile reinforcement cage are embedded into a bearing platform, then performing first concrete pouring, and making the concrete part which belongs to the protective layer and is formed by the first concrete pouring be called a first part 403 of the concrete of the protective layer, and as shown in fig. 3, making the lower interface of the first part of the concrete of the protective layer have a certain distance with the bottom plate of the basement to be built so as to expose the tubular pile reinforcement cage part. And then, building a bottom plate reinforcement cage of the basement bottom plate, overlapping the bottom plate reinforcement cage and the tubular pile reinforcement cage in the process of building the bottom plate reinforcement cage, then performing secondary pouring, pouring the bottom plate reinforcement cage and the exposed tubular pile reinforcement cage into a whole, and pouring the concrete part belonging to the protective layer formed by the secondary pouring into a second part of the concrete called the protective layer. The pipe pile reinforcement cage is the reinforcement in the protective layer, and the bottom plate reinforcement cage is the reinforcement in the basement bottom plate.
It is worth noting that the vibrating rods are prevented from impacting the pipe pile during the first pouring vibration and the second pouring vibration.
In this embodiment, the concrete belonging to the protective layer is divided into a first part to be poured first and a second part to be poured later, so as to facilitate the overlapping construction of the tubular pile reinforcement cage and the bottom plate reinforcement cage. And the second part of the concrete belonging to the protective layer and the concrete belonging to the basement bottom plate are cast into a whole, thereby being beneficial to seamless connection and strength.
