Abstract
A precast X-type reinforced concrete pile has a taper pile tip and a pile body, wherein the side surfaces of the pile body consists of intersecting planes which form edge angles of the pile body and arc-shaped curved surfaces which are smoothly connected with the planes and are sunken toward the pile body, and the cross section of the pile body is approximately X-shaped. A cage of reinforcement consists of main reinforcements at the edge angels of the pile body, X-shaped hoop reinforcements which are arranged lengthwise along the pile body and are bound onto the main reinforcements, rim-shaped hoop reinforcements which are positioned in the taper pile tip and are also bound onto the main reinforcements, top reinforcements which are positioned in the taper pile tip and are integrally connected with the ends of the main reinforcements, and a pile tip reinforcement mat which consists of X-shaped hoop reinforcements bound onto the main reinforcement, three latitudinal bearing reinforcements and three longitudinal through reinforcements bound onto the X-shaped hoop reinforcements. The utility model has the advantages of large side surface area of the pile body, high pile lateral friction, great ultimate bearing resistance of single pile, and small material consumption of single pile.
Description
The utility model relates to a kind of soft foundation pile foundation, composite foundation is handled and used precast reinforced concrete pile.
No matter the precast reinforced concrete pile that existing soft ground treatment pile foundation and rigid pile composite foundation are used is solid pile or hollow pile, and its pile body side surface is flat surface.The stake top net chip architecture complexity of cage of reinforcement, stirrup is a shaped as frame.The side surface area of the precast reinforced concrete pile pile body of this form of structure is little, and pile side friction is also little, and ultimate bearing capacity of single pile is low, and construction unit is many with the stake amount.Single pile is from great, and is many with material.Thereby this structural shape of existing precast reinforced concrete pile still can not make us very satisfied.
The purpose of this utility model provides that a kind of pile body side surface area is big, pile side friction is high, and ultimate bearing capacity of single pile is big, and construction unit is handled with the stake of prefabricated X steel reinforced concrete with the few soft foundation pile foundation of stake amount, composite foundation.
The utility model is realized by following design.
By the concrete pile body with place the pile body side surface of the precast reinforced concrete pile that the cage of reinforcement in the concrete pile body constitutes to constitute the plane of pile body corner angle by crossing and constitute with the arc-shaped curved surface to the pile body sunken inside of flat circle slip, the pile body cross section is greatly to being the X type.
In order to reduce amount of reinforcement and further to improve the stake frictional resistance, further improving of prefabricated X shaped steel rib concrete pile is, the stake end of prefabricated X shaped steel rib concrete pile is the platform taper, cage of reinforcement is by the main muscle that is positioned at the pile body edges and corners, the X type stirrup of arranging and connecting with main muscle colligation along pile body length, be positioned at the frame type stirrup that connects with the main muscle colligation of stake end platform awl on the pile body axis of symmetry, be positioned on the pile body axis of symmetry with the whole top muscle that is connected of the main muscle end of stake end platform awl and place, stake top and lead to muscle by the X type hoop that connects with main muscle colligation with three broadwises of X type stirrup colligation connection, the stake top reinforced mesh that the logical muscle of three warp-wises constitutes constitutes, have pile extension X shaped steel rib concrete pile interface steel cap by with whole edge protecting angle steel that is connected of main muscle and two ends be connected with adjacent two edge protecting angle steels integral body respectively along last, in, three lacing wires of arranging down constitute.
Each side surface of the prefabricated X shaped steel rib concrete pile pile body that the utility model provides constitutes by being positioned at a plane at rib place and being positioned at two interplanar cambered surfaces, so the pile body side surface area is big, the pile foundation side friction is big, and ultimate bearing capacity of single pile is big.Compare with the barrette of existing unidimensional specification, the pile body side surface area increases 12.7%, and pile side friction improves 12.7%, and ultimate bearing capacity of single pile improves 9.7%.Single pile is compared with the solid squares stake of existing unidimensional specification from heavy and light, few with material, and concrete amount reduces 32.6%.
