Abstract
The utility model discloses a pile foundation structure with a combined rod and small masonry amount, which belongs to the technical field of municipal engineering and solves the problem that a pile foundation bearing platform main body is overlarge to influence underground pipelines.
Description
Technical Field
The utility model belongs to the technical field of municipal engineering, and particularly relates to a pile foundation structure with a small masonry amount and a rod combining piece.
Background
The urban road is a life line of a city, various urban pipelines are buried under a small space, various rod pieces are very necessary for saving urban space in recent years, and due to the fact that more facilities are arranged on the rod pieces, the safety requirement on the pile foundation of the rod pieces is higher, and the contradiction between the larger pile foundation and the limited space under the urban road is more and more prominent, the utility model provides a pile foundation structure with small masonry amount of the combined rod pieces, reduces the masonry amount of the pile foundation of the combined rod pieces, and avoids the influence on the existing underground pipelines.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to fulfill the functions related to the background art, the present invention provides a pile foundation structure with a rod combination and a small masonry amount
The technical scheme is as follows: a pile foundation structure with small masonry capacity for rod combination members comprises a bearing platform main body and two precast piles, wherein the bearing platform main body is made of reinforced concrete, a plurality of anchor bolts used for connecting the rod combination members are arranged in the bearing platform main body in the vertical direction, a concrete cushion is further arranged at the bottom of the bearing platform, the two precast piles are welded at two ends of the same side of the bearing platform main body in an inclined mode respectively, and the direction of burying each precast pile into the soil is opposite to the extending direction of the rod combination members.
The utility model realizes the following beneficial effects:
through pressing in and closing the opposite precast pile of pole member extending direction, form the pulling force, can not only guarantee to close pole member safety and firm, can also reduce the excavation depth and the cushion cap main part size of pile foundation, avoid the influence to the present situation underground pipeline, reduce the masonry work volume simultaneously.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the disclosure and together with the description, serve to explain the principles of the disclosure.
Figure 1 is a top view of a close-rod small-volume pile substructure;
figure 2 is a cross-sectional view of a close-bar low-volume pile substructure taken along line a-a.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Examples
Referring to fig. 1-2, a small masonry pile foundation structure with combined bars comprises a bearing platform main body 10 made of reinforced concrete and two precast piles 20, wherein the concrete ratio of the concrete poured by the bearing platform main body is C30, a plurality of anchor bolts 11 for connecting the combined bars are arranged in the bearing platform main body 10 along the vertical direction, a concrete cushion 30 is further arranged at the bottom of the bearing platform main body 10, the concrete cushion is preferably a plain concrete cushion, the plain concrete ratio is C15, the two precast piles 20 are respectively welded at two ends of the same side of the bearing platform main body 10 in an inclined manner, and the direction of burying each precast pile 20 in the soil is opposite to the extending direction of the combined bars.
In this embodiment, every the precast pile top extends there are two reinforcing bars 21 of bending, just two the reinforcing bar 21 of bending welds respectively on the reinforcing bar that the cushion cap main part two sides corresponds, and the design makes the reinforcing bar of bending and the inside reinforcing bar welding seam high quality of cushion cap main part like this, from the inside drop of cushion cap when avoiding the precast pile to pile.
In the present embodiment, both the precast piles 20 are inclined 30 ° with respect to the platform body 10, and the inclination angle may be adjusted appropriately according to the site conditions.
In this embodiment, the two precast piles 20 are square piles with a size of 250 × 250mm, and in order to improve the efficiency of inserting the square piles into the ground, it is considered that the tapered pile tips 22 are provided at the bottoms of the two square piles, and the tapered pile tips 22 are used to easily push the square piles into the ground, thereby preventing the pile bodies from being broken.
In this embodiment, in order to further protect the platform main body and prevent the surface of the platform main body 10 from cracking, it is considered that an expansive concrete protection layer 40 is laid on the outer top surface of the platform main body 10, wherein the strength ratio of the expansive concrete is C50, and in order to protect the anchor bolts 11 exposed outside the platform main body, a plain concrete protection layer 50 is laid on top of the expansive concrete protection layer, wherein the ratio of the plain concrete is C15.
When the prefabricated pile foundation is used, firstly, the inclination angle of the prefabricated pile 20 is confirmed according to site conditions, the bent reinforcing steel bars 21 extending from the top of the two prefabricated piles 20 are respectively welded with the reinforcing steel bars corresponding to the two surfaces of the bearing platform main body according to the confirmed inclination angle, then, the reinforcing steel bars and the prefabricated pile 20 which is well welded are dropped into the excavated soil layer, after all embedded parts and embedded pipelines are confirmed to be correct, concrete is poured, and finally, rod combining rod pieces are installed.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
