Embodiment 1

[0020] Combine below figure 1 The structural composition of the horizontal force transmission guarantee system of the pile row wall support structure of the present invention is described in detail.

[0021] Such as figure 1 As shown, the horizontal force transmission guarantee system of the pile wall support structure of the present invention includes: concrete pile wall 1, embedded parts 2, section steel force transmission structure 3, steel purlin 4, and steel bar skeleton 5. Among them, the embedded part 2 is pre-fixed at the design position of the steel bar frame 5, and is placed together with the steel bar frame 5 to the design position of the concrete pile row wall 1, and the concrete pouring of the concrete row pile wall 1 is carried out after the sinking is completed; if the concrete If the centers of the piles in the pile row wall 1 are not on the same horizontal line, when the foundation pit is excavated to the position of the embedded part 2, the concrete on the s...

Embodiment 2

[0023] Please continue to refer figure 1 , the present invention also provides a design method for the horizontal force transmission guarantee system of the pile row wall support structure. The method comprises the steps of:

[0024] Step 1: Fix the embedded part 2 to the designed position of the steel skeleton 5 of the concrete pile wall 1 through anchoring steel bars in advance.

[0025] Step 2: sinking the embedded part 2 and the steel skeleton 5 to the designed position in the concrete pile wall 1 .

[0026] Step 3: Carry out pouring of the concrete row pile wall 1 .

[0027] Step 4: If the centers of the piles in the concrete pile row wall 1 are not on the same horizontal line, after the foundation pit is excavated to the position of the embedded part 2 on the steel skeleton 5 of the concrete pile row wall, the concrete on the surface of the concrete pile row wall 1 is removed, Embedded part 2 is exposed.

[0028] Step 5: Connect the steel purlin 4 with the embedded p...

Abstract

The invention discloses a horizontal force transmitting guaranteeing system of a pile-in-row wall supporting structure and a design method of the horizontal force transmitting guaranteeing system and belongs to the technical field of building construction. The horizontal force transmitting guaranteeing system of the pile-in-row wall supporting structure and the design method of the horizontal force transmitting guaranteeing system are used for solving the problem that in actual use of an existing steel enclosing purline, a stress model is not consistent with design. According to the horizontal force transmitting guaranteeing system of the pile-in-row wall supporting structure and the design method of the horizontal force transmitting guaranteeing system, firstly, an embedded part is arranged at the design position of a concrete pile-in-row wall steel bar framework, and the embedded part and the steel bar framework are together placed into the design position in a concrete pile-in-row wall in an immersion manner; then pouring of the concrete pile-in-row wall is performed; and finally, if the situation that pile centers of the arc-shaped concrete pile-in-row wall are not on the same horizontal line occurs in the construction process, measures are taken, the embedded part is connected with the steel enclosing purline through a profile steel force transmitting structure, and therefore the concrete pile-in-row wall can be fixedly connected with the steel enclosing purline, and the safety of the steel enclosing purline is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a horizontal force transmission guarantee system and a design method for a pile wall support structure. Background technique [0002] At present, with the rapid development of the modern construction industry, especially the construction scale, the depth of the construction foundation pit is getting larger and larger. The foundation pit support structure is generally used in deep foundation pit engineering to ensure the safety of the foundation pit excavation process. In the foundation pit support structure, the concrete row pile wall is widely used because it is applicable to the large excavation depth of the foundation pit and has a water-stop effect. However, in actual engineering, it is difficult to ensure that the centers of the piles on the concrete pile wall are located on the same horizontal line during the construction process, which makes the steel purlin...
