Embodiment Construction
[0049] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0050] see Figure 1-Figure 2 , a prestressed inclined pile support, comprising an inclined pile support 11, a purlin 8, a pullout device 1, and a loading device 4; the inclined pile support 11 is driven into the soil before excavation; 8 for support; the anti-pull device 1 is flexibly connected with the inclined pile support 11 in the axial direction; It is fixed in the purlin 8, and the loading device 4 is installed on the part where the upper end protrudes from the purlin 8. It should be noted that the prestressing device for inclined piles is located outside the ring beam, which has a wide application range and can extend to the ground to avoid the impact of groundwater due to the ring beam falling to the bottom.
[0051] As a preferred embodiment, the anti-pull device 1 is a steel pipe sleeved on the inclined pile support 11, the upper e...
