[0005] The present application provides a construction process for a groove-free and backfill-free pile-and-ground raft foundation, comprising the following steps:

[0006] Multiple supporting piles are poured under the ground by reinforced concrete;

[0007] The raft slab is cast on the ground by reinforced concrete and fixed on top of a number of supporting piles.

[0008] Furthermore, in some embodiments of the present invention, a bottom insulation board is laid on the bottom of the raft.

[0009] Furthermore, in some embodiments of the present invention, side insulation boards are laid at the bottom of the raft and along the peripheral sides of the raft, and the side insulation boards surround the plurality of support piles.

[0010] Furthermore, in some embodiments of the present invention, the side insulation boards are laid vertically, and the depth of the side insulation boards reaches the standard depth of the antifreeze layer.

[0011] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0012] The embodiment of the present invention provides a construction process for a groove-free and backfill-free pile and ground raft foundation, comprising the following steps:

[0013] Multiple supporting piles are poured under the ground by reinforced concrete;

[0014] The raft slab is cast on the ground by reinforced concrete and fixed on top of a number of supporting piles.

[0015] It is achieved by driving piles below the ground and then pouring a raft slab on the ground, thus eliminating the construction steps of trenching, backfilling, and cushioning, and at the same time enhancing the bearing capacity, improving the construction efficiency, and saving the construction period.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0022] In the description of the embodiments of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, or are the orientation or position relationship in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc., if used, are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0023] In addition, the use of terms such as "horizontal" and "vertical" does not mean that the components must be absolutely horizontal or vertical, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
