Problems solved by technology

[0003] 1. The construction efficiency is low and the safety is not enough: in the construction process, the pipe piles are generally aligned up and down by the crane on site, and then welded, the overall operation time is long, and there are certain safety hazards;
[0004] 2. The integrity and durability of pipe piles are poor: pipe piles connected by welding are prone to fall off under long-term corrosion in the soil, and pipe piles not only need to bear axial pressure, but also are used for retaining soil and anti-skid The working condition of the horizontal load such as shifting, and the pipe pile in the prior art is not connected inside, which leads to its poor integrity and horizontal bearing capacity

Embodiment 1

[0037] refer to figure 1 and figure 2 , which is the first embodiment of the present invention, this embodiment provides a method of using a built-in pipe pile connection device, a method of using a built-in pipe pile connection device,

[0038] S1: uniformly distribute and fix several vertically extending connecting steel bars 102 along the circumferential direction;

[0039] S2: Put the pipe piles on the outside of each connecting steel bar 102, and slide down to the bottom;

[0040] S3: install the limiting ring 201 on the inner side of the connecting steel bar 102, so that each connecting steel bar 102 is buckled in the corresponding groove 202 on the limiting ring 201; and limit the reinforcing ring 301 to the periphery of each connecting steel bar 102;

[0041] S4: Sleeve the middle sealing plate 103 on the connecting steel bar 102, remove the reinforcement ring 301, and insert the lower end of the casing 105 on the middle sealing plate 103 into the top of the pipe pi...

Embodiment 2

[0048] refer to Figure 2-7 , is the second embodiment of the present invention, which is based on the previous embodiment.

[0049] Specifically, it also includes that the bottom sealing plate 101 is fixed at a specified position by concrete pouring, welding or screws, so as to limit the position of the pipe pile.

[0050] Preferably, the connecting steel bar 102 is fixed on the bottom sealing plate 101 through the cooperation between the movable part 401, the telescopic part 402, the reinforcement part 403 and the limiting part 404, and the bottom end of the connecting steel bar 102 is inserted into the inside of the fixed pipe 404a , the connecting steel bar 102 is initially limited by the fixed pipe 404a, and at this time, the connecting steel bar 102 is further limited by the setting of the reinforcing rod 403a and the arc-shaped block 403b, so as to avoid the position of the lower part from easily occurring during installation and use. Bending will affect the integrity ...

Embodiment 3

[0057] refer to Figure 1-7 , is the third embodiment of the present invention, which is based on the first two embodiments.

[0058] Specifically, according to the actual construction requirements, repeating the above operations can install multiple limit rings 201 and middle sealing plates 103 more quickly, so as to perform stacking and installation of pipe piles. When multiple pipe piles need to be connected, repeat the above steps directly. It can be operated. Compared with the welding method in the prior art, the installation efficiency of the device is higher, and the connection strength between two adjacent pipe piles is stronger, and more pipe piles can be stacked at a time. Concrete pouring, work efficiency is higher.

[0059] Preferably, concrete is poured through the through hole M on the limit ring 201 and the passing concrete hole 104 on the middle sealing plate 103, so that the integrity between the various pipe piles is strengthened, and through the through hol...

Abstract

The invention discloses a method for using a built-in pipe pile connection device, which comprises the steps of uniformly distributing and fixing several vertically extending connecting steel bars along the circumferential direction; Bottom; the limit ring is installed on the inner side of the connecting steel bar, so that each of the connecting steel bars is buckled in the corresponding groove on the limit ring; and the reinforcing ring is limited to the periphery of each of the connecting steel bars ; Sleeve the middle sealing plate on the connecting steel bar, remove the reinforcement ring, and insert the lower end of the casing on the middle sealing plate into the top of the pipe pile. The construction method of the present invention can complete the docking of each section of the pipe pile without welding, and the construction efficiency is greatly improved, and the inside of the pipe pile is connected and limited, which greatly improves the concrete forming of the pipe pile. The integrity of the rear, as well as the bearing capacity of horizontal anti-soil, anti-slip, etc., the safety and service life are higher.

Description

technical field [0001] The invention relates to the technical field of pipe pile foundation construction in civil engineering, in particular to a method for using a built-in pipe pile connection device. Background technique [0002] At present, in the construction of prefabricated HPC pile foundations in civil engineering, the welding pile method is widely used to meet the individual needs of different pile lengths for different projects. On-site operations are usually performed after the upper and lower HPC pipe piles are centered, and then the upper and lower HPC pipe piles are aligned. The pile end plate is fixed by spot welding, and then welded continuously along the joint of the HPC pipe pile end plate, and the pile is pressed or piled after the weld is cooled. property, but the pipe piles in the prior art have the following problems: [0003] 1. The construction efficiency is low and the safety is not enough: in the construction process, the pipe piles are generally a...
