[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Reference Figure 1 and Figure 2 As shown, the utility model provides a swastika-shaped external scaffolding for the pile connection construction of supporting piles, comprising: an outer vertical pole 1, an inner vertical pole 2, and a small cross bar 3.

[0020] In this embodiment, a slope top platform is formed on the upper part of the supporting pile. The steel bars 7 of the supporting pile are extended at the top of the supporting pile. Since the slope top platform is relatively narrow, conventional scaffolding cannot be set on opposite sides of the extended steel bars of the supporting pile to serve as a template for the construction of the connected piles of the casting supporting piles.

[0021] In this embodiment, two rows of outer upright poles 1 are arranged in the same direction, and are vertically arranged outside the slope top platform 6 of the supporting piles. Each row of outer upright poles 1 is arranged along the row direction of the supporting piles.

[0022] A row of inner side poles is vertically arranged on the inner side of the slope top platform 6. A row of inner side poles 2 is arranged in the same direction as each row of outer side poles 1.

[0023] In this embodiment, each row of outer uprights 1 and one row of inner uprights 2 respectively include a plurality of steel pipes arranged in a row. Each steel pipe is arranged vertically. The plurality of steel pipes arranged in a row are connected together by a transverse pipe. The transverse pipe is connected to the vertically arranged steel pipe by a fastener.

[0024] There are multiple small crossbars 3. One end of the small crossbar 3 is connected to two rows of outer vertical poles 1. The other end of the small crossbar 3 is connected to a row of inner vertical poles 2 and supported on the upper step slope 8 of the slope platform. The position of the small crossbar 3 corresponds to the position of the drainage hole of the supporting pile. The middle part of the small crossbar 3 is detachably provided with a drainage pipe 4. The drainage pipe 4 is used to be buried in the supporting pile. After the supporting pile is extended, the drainage pipe 4 is buried in the extended pile of the supporting pile, and the inner hole of the drainage pipe is used as the drainage hole.

[0025] The swastika external scaffold for pile connection construction of supporting piles of the utility model also includes an anchor 5. The anchor 5 is connected to the other end of the small cross bar 3. It is buried in the upper step slope 8.

[0026] As a preferred embodiment, the anchoring member 5 includes an anchor plate 51 , an anchor nail 52 and a plug connector 53 .

[0027] The anchor plate 51 is attached to the slope of the upper step slope 8. A socket hole is formed at the other end of the small cross bar 3. A plug connector 53 is connected to the outer side of the anchor plate 51. The plug connector 53 is detachably inserted into the socket hole.

[0028] The anchor 52 is anchored in the slope surface of the upper step slope 8. One end of the anchor 52 is rotatably connected to the inner side of the anchor plate 51.

[0029] In this embodiment, the socket hole of the small cross bar is formed with an internal thread, and the outside of the plug connector is formed with an external thread, and the plug connector is screwed into the socket hole of the small cross bar.

[0030] In this embodiment, the construction project to be built is located on the west side of a school and close to the municipal road. The original slope top is the red line, and the red line to the site is a natural slope. The current excavation support position is located on the west side of the school, and the support length is about the slope. There is still a height difference of 5.6 to 7.8m between the site's positive and negative zero elevation and the municipal road elevation (slope top). The support range is limited, there is no slope space, and some positions below the site's positive and negative zero elevation still have a maximum fill of about 7.0 to 8.0m. The support length is about 178m, and the maximum height difference is about 7.8m. The rotary bored pile cannot be formed at one time and the pile connection measures are taken. The slope support safety level is level one, and the design service life of the support structure is 50 years. The support pile row adopts rotary bored piles with a pile diameter of 1200 and 1400mm, a spacing of 1.8 to 2.5m, a pile body concrete strength of C30, and a total number of 89 piles.

[0031] Because there is still a height difference of 5.6 to 7.8m between the current ground elevation of the site and the elevation of the municipal green belt (designed slope top elevation), the support range is limited, there is no slope space, and the rotary bored piles cannot be formed in one go, so the pile connection measure is adopted. The constructed rotary bored piles must be connected to the designed pile top elevation before the crown beam construction can be carried out, and the pile connection height is about 3.5 to 5.0m.

[0032] After the lower rotary drilling piles were broken, the pile foundation construction platform (i.e. the slope top platform) was narrow, and it was impossible to set up a guy wire to fix the external scaffolding when supporting the upper scaffolding. Therefore, the project carried out technical research and invented a swastika-shaped external scaffolding for the construction of supporting piles.

[0033] After the reinforcement of the supporting piles is extended and the longitudinal and transverse reinforcements are tied, the formwork on both sides is closed, drainage hole sleeves are reserved in the formwork according to the requirements of the drawings, and double rows of outer vertical poles are set up on the outside of the formwork in a conventional manner. After the small cross bar passes through the drainage hole, it is connected to the inner vertical pole to form a stiletto-shaped stable support structure.

[0034] The utility model discloses a swastika external scaffolding for pile connection construction of supporting piles, which occupies a small area and overcomes the difficulty of setting up a supporting structure due to a small site. It has a safe bearing capacity and can take into account the support of templates on both sides of the inside and outside, so the construction is convenient, safe and reliable.

[0035] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical solution.
