The pile foundation usually consists of piles and pile bearing platforms connected with the pile tops, and if the pile bodies are completely buried in the soil and the bottom surfaces of the bearing platforms are in contact with the soil body, the pile foundation is called a low bearing platform pile foundation; when the upper part of the pile body is exposed out of the ground and the bottom of the pile cap is positioned above the ground, the pile body is called a high pile cap pile foundation. No matter it is low pile foundation or high pile foundation, for track or building construction operation, pile foundation construction all is comparatively important construction link.
It is often difficult to ensure that each pile body is highly level during pile foundation construction operations. Moreover, since a track project usually requires several months or years, in a pile foundation construction area with complicated geological conditions such as frozen earth and soft and thick soil layers, even if each pile body is constructed to approximately the same height, each pipe pile will settle to different degrees along with the lapse of time and the change of natural environment, and in order to ensure the smoothness of the rail surface to improve the riding comfort, the settlement range of the pile foundation must be reduced as much as possible.
In order to reduce or prevent that the pile foundation from subsiding, chinese utility model patent (CN201924250U) discloses a pile foundation pile body for handling short embankment deep soft soil foundation of railway, this pile foundation is including being located the compound foundation outside the embankment core stress zone, this embankment core stress zone is the following region of 45 spread angle within ranges in ballastless track supporting layer both sides, this compound foundation top surface is equipped with the rubble bed course, still be equipped with geogrid in the middle of this rubble bed course, it is equipped with the bored concrete pile to be located embankment core stress zone, be equipped with the continuous sheet girder of reinforced concrete on this bored concrete pile bolck.
As another example, the chinese utility model patent (CN204455724U) discloses an integrated structure for roadbed rails in deep soft soil areas, the integrated structure at least comprises a sleeper embedded supporting plate, two parallel prefabricated sleeper blocks are embedded on the upper end surface of the sleeper embedded supporting plate, and the prefabricated sleeper blocks are provided with steel rails and fasteners for rail structures; anti-creeping steel bars for connecting two prefabricated sleeper blocks are arranged in the sleeper embedded supporting plate, and plate steel bars are also arranged in the sleeper embedded supporting plate; the lower part of the middle part of the sleeper embedded supporting plate is provided with midspan supporting beams at intervals, and a midspan precast pile for supporting the midspan supporting beam is arranged in a soft soil area below the midspan supporting beam; a cross-end supporting beam is arranged at the lower part of the end part of the sleeper embedded supporting plate, and a cross-end precast pile for supporting the cross-end supporting beam is arranged in a soft soil area at the lower part of the cross-end supporting beam; the middle-span supporting beam and the end-span supporting beam are respectively provided with a middle-span beam reinforcing steel bar and an end-span beam reinforcing steel bar; the reinforcing steel bars for the midspan beam and the reinforcing steel bars for the plates are arranged in a staggered mode.
