Description

Technical Field

[0001] The invention relates to the technical field of foundation pit support engineering construction, in particular to a guide wall template for interlocking pile concrete guide wall. Background Art

[0002] With the continuous development of my country's economy, bored interlocking cast-in-place piles for foundation pit support have gradually been widely used in design and construction. The interlocking piles for foundation pit support are generally continuous circular concrete piles connected crosswise. Before the construction of interlocking piles, it is necessary to cast concrete guide walls to provide a working surface for the interlocking pile pile forming machinery. The guide wall formwork generally uses wooden formwork to make an arc-shaped formwork system on site. Since the quality of production and support depends on the operation level of the construction personnel, it often leads to different degrees of deviation in the formwork system, and ultimately cannot guarantee the quality of concrete guide wall forming, which is not conducive to the construction of interlocking piles, thus affecting the construction quality and progress of interlocking piles. Therefore, in order to eliminate the occurrence of such problems in such engineering construction, a method for the construction of interlocking pile concrete guide walls is studied to improve the quality of guide wall concrete forming and speed up the construction progress. Summary of the invention

The first angle steel 2 and the second angle steel 5 are fixed together by the first bolt 7 that passes through the first mounting hole 4 and the second mounting hole 6. The two ends of the two second angle steels of the same layer corresponding to each shaped steel template are connected together by the third angle steel 10. The length direction of the shaped steel template is also provided with a length direction wooden template 13. The length direction wooden template 13 is arranged at intervals on one side of the arc-shaped protrusion of the shaped steel template.

The guide wall inner side shaped steel formwork 1 is placed according to the bite pile position, which solves the problem of different degrees of template system deviation when supporting wooden formworks in such projects, which leads to poor concrete forming quality of the guide wall. The problem of the fixed formwork is solved. At the same time, the flanges are provided around the fixed steel formwork to effectively increase the rigidity of the fixed steel formwork itself; a second angle steel 5 is placed at the upper and lower ends of the fixed steel formwork 1 in the length direction on both sides, and a second mounting hole 6 is opened in the horizontal section of the second angle steel 5 corresponding to the position of the first mounting hole 4.

The second fixing plate 9 is connected, and the third angle steel 10 is placed at equal intervals along the length direction of the second angle steel 5. The third angle steel 10 opens a fourth mounting hole 11 at the position corresponding to the third mounting hole 8 in the horizontal section. The second angle steel 5 and the third angle steel 10 are connected by a second bolt 12 through the third mounting hole 8 and the fourth mounting hole 11, which effectively supports and reinforces the fixed template. At the same time, the angle steels are connected with bolts to facilitate installation and removal, thereby improving construction efficiency. The wooden template 13 is placed along the control line outside the guide wall, and the wooden template 13 is horizontally backed with a wooden square 14. The outer side of the wooden square 14 in the length direction of the guide wall corresponds to the first fixed template. Two scaffolding tubes 15 are placed at the positions of the fixed plate 3 and the second fixed plate 9, the bottom of the scaffolding tube 15 is anchored into the foundation, and the top is connected to the first fixed plate 3 and the second fixed plate 9 respectively through tension bolts 16. A single fixed scaffolding tube 17 with the bottom anchored into the soil is placed outside the wooden square 14 in the short side direction of the guide wall according to the length of the template. A shorter length of anchor scaffolding tube 18 is placed a certain distance outward from the fixed scaffolding tube 17, and the top of the fixed scaffolding tube 17 is obliquely connected to the bottom of the anchor scaffolding tube 18 by a diagonal brace scaffolding tube 19, so that the overall template system of the guide wall is firm and reliable, the construction is convenient and quick, and the construction progress is accelerated.
