Detailed description of the invention
The present invention is described in further detail in conjunction with accompanying drawing below by specific embodiment.
As Figure 1-4, this application provides concrete filled steel tube stand column pile and become label synchronization continuous placing method under water, realize by building device, build device and include steel pipe column 1 and hole, stake position 2, steel pipe column 1 is positioned at hole, stake position 2.
Casting method is implemented as follows:
Step S00: as it is shown in figure 1, inject the first concrete 51 by conduit 3 in hole, stake position 2, until face of the building absolute altitude of the first concrete 51 is consistent with design interface 10 absolute altitude. The first concrete 51 is low-grade concrete, is positioned at the bottom in hole, stake position 2. Design interface 10 is the first concrete 51 and the default interface of the second concrete 52, is typically implemented setting.
Step S10: as in figure 2 it is shown, inject the second concrete 52 in hole, stake position 2 by conduit 3, until face of the building absolute altitude of the second concrete 52 is consistent with default stake end face 20 absolute altitude. The second concrete 52 is high-grade concrete, is positioned at the top of the first concrete 51, and presetting stake end face 20 is that the effective stake top mark of bored concrete pile is high.
Step S20: as it is shown on figure 3, fill obstacle 6 between a part of lateral wall of steel pipe column 1 and medial wall, hole 2, stake position in gap.
Step S30: as shown in Figure 4, continues to build the second concrete 52, until the laitance 4 in steel pipe column 1 overflows from the top of steel pipe column 1, has built.
The concrete filled steel tube stand column pile that the application provides becomes label under water and synchronizes continuous placing method, by conduit, the first concrete and the second concrete are directed in hole, stake position, operating process is very simple and convenient, optimised coagulation soil column build flow process, reduce difficulty of construction.
In the present embodiment, preferably, as shown in Figures 1 and 2, when building the first concrete 51 and/the second concrete 52, the mouth of pipe controlling conduit 3 moves so that the mouth of pipe face absolute altitude of conduit 3 changes according to the change of concrete upper surface absolute altitude.
