Problems solved by technology

[0004] At present, the construction technology of SMW construction method has gradually matured, but there are still some problems in the actual construction process on site, such as: 1. The positioning of SMW construction method piles is not accurate before construction, resulting in a large deviation of the center of the finished product, which increases safety hazards; 2. Internal There is no special fixing device for inserting H-shaped steel, which causes a large deviation in verticality of inserted H-shaped steel, which breaks through the pile body of SMW construction method, resulting in poor waterproof effect and increased safety hazards

Embodiment 1

[0030] Such as Figure 1 to Figure 3 As shown, a SMW construction method pile-shaped steel fixing device includes a guide beam 1, two guide beams 1 are arranged in parallel, a positioning mechanism is arranged between the two guide beams 1, and the positioning mechanism includes an adjustment assembly 1 and an adjustment assembly 2. The first assembly can be adjusted between the two guide beams 1, and the second adjustment assembly can be adjusted on the first adjustment assembly. The position is fixed through the adjustment assembly one and the second adjustment assembly pair of profile steel. Use the adjustment component one to slide to any position on the guide beam 1, while ensuring the distance between the two guide beams 1, and then combine the adjustment component two to make the profiled steel be positioned horizontally and longitudinally. The second adjusting component is inserted vertically to ensure its precise positioning.

[0031] In a further preferred solution of ...

Embodiment 2

[0035] Such as Figure 4 As shown, it is further improved on the basis of embodiment 1. The bottom of the guide beam 1 is provided with a leveling assembly. The leveling assembly includes a support base 14, a rotating rod 15 and a bottom plate 16. The support base 14 and the guide beam 1 are detachably connected, Two rotating rods 15 are provided symmetrically. One end of the rotating rod 15 is rotatably connected to the bottom surface of the support base 14, and the other end of the rotating rod 15 is slidably connected to the bottom plate 16. The rotating rod 15 is provided with a fixing device for fixing with the bottom plate 16. Locking pieces. The height of the support base 13 is adjusted by rotating the rotating rod 15 while the guide beam 1 is leveled. At the same time, the bottom of the rotating rod 15 and the bottom plate 16 slide, and then the bottom plate 16 is connected to the bottom plate 16 by the locking member on the rotating rod 15 Rotate the rod 15 to achieve ...

Embodiment 3

[0038] A construction method of SMW construction method pile-shaped steel fixing device includes the following steps:

[0039] S1. Installation of guide beam 1: excavate the SMW construction method pile construction guide trench according to the drawing, place leveling components on both sides of the guide trench according to the positioning device, and fix the guide beam 1 on the support base 14 of the leveling component by bolts, and Adjust the rotating rod 15 until the guide beam 1 is in a horizontal state, and then connect and fix the rotating rod 15 with the bottom plate 16 through a locking piece. The center line of the leveling components on both sides is the center line of the positioning tool;

[0040] S2. Installation of adjustment assembly 1 and adjustment assembly 2: The two connecting rods 2 are placed flat on the guide beam 1, and the two ends of the adjusting member 7 are connected to the corresponding positioning blocks 8 respectively, and the connecting rod 2 and th...

Abstract

The invention discloses an SMW construction method pile section steel fixing device and a construction method, and belongs to the technical field of construction method pile construction. The device comprises two guiding beams which are arranged in parallel, a positioning mechanism is arranged between the two guiding beams, the positioning mechanism comprises a first adjusting assembly and a second adjusting assembly, the first adjusting assembly is adjustably arranged between the two guiding beams, the second adjusting assembly is adjustably arranged on the first adjusting assembly, and the position of section steel is fixed through the first adjusting assembly and the second adjusting assembly. According to the device and the method, the first adjusting assembly can slide to any positionon the guiding beams, meanwhile, the distance between the two guiding beams can be guaranteed, and then the second adjusting assembly is combined to enable the section steel to be transversely and longitudinally positioned, and the section steel is kept vertically inserted downwards through the second adjusting assembly in the downward inserting process, so that accurate positioning on the section steel is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of construction method pile construction, and specifically relates to a fixing device used for quick installation of section steel during SMW construction method pile construction. Background technique [0002] The SMW method uses a multi-axis drilling mixer to drill to a certain depth on site. At the same time, a cement-based strengthening agent is sprayed at the drill bit to be repeatedly mixed and stirred with the foundation soil, and overlapping construction is adopted between the construction units. Then insert H-shaped steel or steel plate as the stress reinforcement material before the cement-soil mixture is hardened. When the cement hardens, a continuous, complete, jointless underground wall with certain strength and rigidity is formed. [0003] With the rapid development of China's construction industry in recent years and the current shortage of land applications, more and more engineering projects adopt ...
