Abstract
A mucky soil pile foundation dado structure is characterized in that steel pipe piles and Larsen steel plate piles which are arranged at intervals along a ring form a main body of a pile foundation dado together, so that the excellent bending resistance of the steel pipe piles and the excellent water stopping effect of the Larsen steel plate piles are utilized simultaneously; and the inner side of the pile foundation dado is provided with a purlin comprising a beam support and a waist beam, the outer sides of part of the steel pipe piles or the Larsen steel sheet piles are also connected with anchor cables, and the end parts of the anchor cables penetrate through the steel pipe piles or the Larsen steel sheet piles to be fixed with the purlin. The mucky soil pile foundation retaining wall structure has good structural strength and water stopping capacity, and can effectively meet the construction requirements of excavation of mucky soil foundation pits.
Description
Technical Field
The utility model relates to a pile foundation dado especially relates to a pile foundation dado structure of installing in mucky soil.
Background
When excavation of a foundation pit is carried out, in order to prevent the hole wall from collapsing and ensure that the shape of the foundation pit is unchanged, the excavated soil generally needs to be subjected to foundation pit bracing to serve as a temporary structure for construction. However, for areas similar to beach mucky soil, slope excavation cannot be directly performed, and requirements cannot be met no matter the strength of the pile foundation retaining wall or the water stopping capacity.
Disclosure of Invention
An object of the utility model is to provide a pile foundation dado structure suitable for in mucky soil to satisfy the foundation ditch excavation needs in mucky soil area.
The mucky soil pile foundation dado structure comprises steel pipe piles and Larsen steel plate piles which are arranged at intervals along the ring shape, and the adjacent sides of the steel pipe piles and the Larsen steel plate piles are fixed by welding; and the surrounding purlins are annularly fixed on the inner sides of all the steel pipe piles and the Larsen steel plate piles, the outer sides of part of the steel pipe piles or the Larsen steel plate piles are also connected with anchor cables, and the end parts of the anchor cables penetrate through the steel pipe piles or the Larsen steel plate piles to be fixed with the surrounding purlins.
The utility model discloses a mucky soil pile foundation dado structure, including vertical and horizontal two support parts, vertical support part comprises steel-pipe pile and Larsen steel sheet pile, and they have formed the main part of pile foundation dado jointly, have utilized the excellent bending resistance of steel-pipe pile and the outstanding stagnant water effect of Larsen steel sheet pile simultaneously, make the pile foundation dado can satisfy the intensity requirement and the stagnant water requirement that the foundation ditch excavated; the transverse supporting part consists of an anchor cable and an enclosing purlin, after the main body of the pile foundation dado is installed, the anchor cable is firstly constructed, then tensioning is carried out, after tensioning is completed, the enclosing purlin is installed, and the enclosing purlin and the end part of the anchor cable are fixed to form a whole. The mucky soil pile foundation dado structure has good structural strength and water stopping capacity, can provide reliable support for a foundation pit, effectively ensures the supporting effect of a deep foundation pit, and improves the safety in the process of foundation pit excavation and construction operation.

Detailed Description
A mucky soil pile foundation dado structure comprises steel pipe piles 1 and Larsen steel plate piles 2 which are arranged at intervals along the ring shape, wherein the adjacent side edges of the steel pipe piles and the Larsen steel plate piles are fixed through welding; and the surrounding purlins 3 are annularly fixed on the inner sides of all the steel pipe piles and the Larsen steel plate piles, the outer sides of part of the steel pipe piles or the Larsen steel plate piles are also connected with anchor cables 4, and the end parts of the anchor cables penetrate through the steel pipe piles or the Larsen steel plate piles to be fixed with the surrounding purlins.
The mucky soil pile foundation dado structure is characterized in that a welding locking notch is arranged at the joint of the steel pipe pile 1 and the Larsen steel plate pile 2, and the steel pipe pile 1 and the Larsen steel plate pile are tightly combined in a locking notch welding mode, so that the structural strength of the steel pipe pile foundation dado structure is improved.
Enclose purlin 3 and include that the joist support 5 with install in the waist rail 6 at the joist support top, the tip of anchor rope 4 is connected on waist rail 6. The joist support is welded and fixed on the inner side of the pile foundation dado, the waist beam is simultaneously connected with the joist support, the steel pipe pile and the Larsen steel sheet pile, and stress is dispersed and transmitted through the joist support so as to avoid stress concentration and damage the pile foundation dado and improve the safety of the pile foundation dado. The anchor cable 4 is a prestressed anchor cable to improve the structural strength.
The muddy soil pile foundation dado structure comprises a vertical supporting part and a transverse supporting part, wherein the vertical supporting part consists of a steel pipe pile and a Larsen steel plate pile which jointly form a main body of the pile foundation dado, and the excellent bending resistance of the steel pipe pile and the excellent water stopping effect of the Larsen steel plate pile are utilized, so that the pile foundation dado can meet the strength requirement and the water stopping requirement of foundation pit excavation; the transverse supporting part consists of a prestressed anchor cable and a surrounding purlin, after the main body of the pile foundation dado is installed, the prestressed anchor cable is firstly constructed, then tensioning is carried out, after the tensioning is finished, a beam support is installed, then a waist beam is placed on the beam support, then the prestressed anchor cable penetrates through the waist beam, and the waist beam and the pile foundation dado main body are welded, so that a whole is formed. The mucky soil pile foundation retaining wall structure has good structural strength and water stopping capacity, and can effectively meet the construction requirements of excavation of mucky soil foundation pits.
