Abstract

The utility model relates to a socket type steel pipe pile joint, which comprises more than two steel pipe piles which are connected sequentially from top to bottom, and is characterized in that an internally connecting sleeve is coaxially and fixedly connected to a butt joint end opening of the two adjacent steel pipe piles in a sleeved manner. By the aid of the socket type steel pipe pile joint, steel pipe pile splicing is more convenient, the pile splicing quality is ensured, and the strength of pile splicing joint point positions is enhanced.

Description

Spigot-and-socket steel pipe pile joint

Technical field

The utility model relates to a kind of spigot-and-socket steel pipe pile joint.

Background technology

The butt joint welding is generally adopted in the connection of two steel pipe pile joints.Because the steel pipe pile wall thickness is thinner, there is the pile extension difficulty during butt joint, the pile extension quality is difficult for guaranteeing that joint area the cracking phenomena that gets loose occurs easily in follow-up pile driving process, influence the steel pipe pile construction quality.

Summary of the invention

The purpose of the utility model is to provide a kind of spigot-and-socket steel pipe pile joint, makes that the steel pipe pile pile extension is convenient, has guaranteed the pile extension quality, has also increased the intensity at pile extension node place.

The purpose of the utility model realizes through following technical scheme: a kind of spigot-and-socket steel pipe pile joint; It comprises the steel pipe pile that connects successively more than two joints from top to bottom, it is characterized in that: coaxial fixed cover connects sleeve pipe in being connected in the craft port of adjacent two joint steel pipe piles.

The utility model has also carried out following improvement:

The craft port periphery wall of adjacent two joint steel pipe piles is installed with an above deep floor.

The method for using of the utility model is following:

1, be inserted in one at following joint steel pipe pile top to be connected and connect sleeve pipe, its part is stretched out outside the steel pipe pile, and (referring to Fig. 1) fixed in spot welding around the junction;

2, through adopting the spigot-and-socket butt joint,, can not produce inconsistent phenomenon, guarantee butt joint welding quality (referring to Fig. 2) to guarantee saving steel pipe pile up and down on same axis;

3, butt weld is behind full weld, and above deep floor of welding between two steel pipe piles is to strengthen the intensity (referring to Fig. 3) of joint position of joints pipe shaft.

Compared to prior art, the advantage of the utility model is: connect sleeve pipe and deep floor through in inside and outside steel pipe pile, adding, adopt the spigot-and-socket butt joint, make that the steel pipe pile pile extension is convenient, guaranteed the pile extension quality, also increased the intensity at node place.

The specific embodiment

Below in conjunction with Figure of description and embodiment the utility model content is elaborated:

Like the embodiment sketch map of Fig. 1 to a kind of spigot-and-socket steel pipe pile joint that provides for the utility model shown in Figure 4.

A kind of spigot-and-socket steel pipe pile joint, it comprises the steel pipe pile 1 that connects successively more than two joints from top to bottom, it is characterized in that: coaxial fixed cover connects sleeve pipe 2 in being connected in the craft port of adjacent two joint steel pipe piles 1.

The craft port periphery wall of adjacent two joint steel pipe piles 1 is installed with an above deep floor 3.

Connect the internal diameter little 0-3 millimeter of the external diameter of sleeve pipe 2 in said than steel pipe pile 1.

The quantity of said deep floor 3 is four, and it is distributed on the periphery wall of steel pipe pile 1.
