Description

Technical Field

[0001] The utility model relates to the technical field of SMW method piles, in particular to a guiding device used for SMW method pile construction. Background Art

[0002] SMW pile method, also known as steel-cement soil mixing (pile) wall, is an underground engineering construction technology. It combines the use of multi-axis drilling and mixing machines and cement-based reinforcers. It drills to a certain depth on site and sprays cement-based reinforcers at the drill bit to mix and stir repeatedly with the foundation soil to form an underground wall with certain strength and rigidity.

[0003] However, after drilling the common SMW piles, when inserting the "H" steel into the mixture of cement and soil, the workers hold the hoisted "H" steel, and the crane gradually lowers the "H" steel. During the descent of the "H" steel, if there is no guide device, it is easy to make the "H" steel tilt, resulting in the foundation made by the SMW piles not being strong enough;

[0004] Therefore, we propose a guiding device for SMW pile construction to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 The utility model provides a technical solution: a guide device for SMW pile construction, comprising: a moving plate 1, a threaded column 2, a threaded sleeve 3, a connecting piece 4, a moving wheel 5, a first supporting plate 6, a first threaded rod 7, a first guide plate 8, a first pulley 9, a first limiting rod 10, a first level detector 11, a first alarm 12, a second threaded rod 13, a second guide plate 14, a second pulley 15, a second limiting rod 16, a second level detector 17, and a second alarm 18;

[0028] When using the guide device for SMW pile construction, if Figure 1 As shown, when the SMW pile construction is adopted, the excavator will leave a groove on the ground. After pouring cement into the ground, the "H"-shaped steel is inserted into the mixture of cement and soil, and the movable plate 1 is moved to the top of the groove. The position relationship between the threaded column 2 and the threaded sleeve 3 on the lower side of the movable plate 1 is adjusted so that the movable plate 1 is in a horizontal state, thereby facilitating the positioning and installation of the "H"-shaped steel.

[0029] like Figure 1 As shown, the threaded columns 2 are distributed in an array on the lower side of the movable plate 1, and the threaded columns 2 are threadedly connected to the threaded sleeves 3, the threaded sleeves 3 are rotatably connected to the connecting pieces 4, and the lower side of the connecting pieces 4 is fixedly installed with movable wheels 5. After the movable plate 1 is placed on the ground, it moves along the direction of the groove, and all the movable wheels 5 move in one direction. Since the construction site is not necessarily flat, the movable plate 1 is not necessarily in a horizontal state. The upper side of the movable plate 1 is fixedly connected with a first level detector 11 and a second level detector 17. From the first level detector 11 and the second level detector 17, it can be observed which position the movable plate 1 is tilted. The threaded column 2 is rotated to extend or shorten the threaded column 2 in the threaded sleeve 3, so that the movable plate 1 is in a horizontal state. When the movable plate 1 is in a horizontal state, the first guide plate 8 and the second guide plate 14 in the movable plate 1 will be perpendicular to the ground, so as to ensure that the "H"-shaped steel can be vertically inserted into the cement pit, thereby ensuring that the foundation is relatively stable. In addition, the first alarm 12 and the second alarm 18 are arranged on the upper side of the movable plate 1. The first alarm 12 and the second alarm 18 monitor the first level detector 11 and the second level detector 17 respectively, so as to reduce the error caused by naked eye observation and affect the insertion angle of the "H"-shaped steel;

[0030] like Figure 1 As shown, after the movable plate 1 is placed on the ground, the threaded sleeve 3 is rotated. Since the threaded column 2 is fixedly connected to the movable plate 1 and the movable wheel 5 is in contact with the ground, when the threaded sleeve 3 is rotated, the threaded sleeve 3 rotates in the connecting member 4, and the threaded column 2 in the threaded sleeve 3 will be extended and retracted in a vertical state, and the movable wheel 5 will not be rotated, so that the movable plate 1 can be adjusted to a horizontal state conveniently;

[0031] like Figure 1 and Figure 2 As shown, since the specifications of the "H"-shaped steel inserted into the construction site are the same during one construction, it is only necessary to adjust the spacing between the first guide plates 8 and the spacing between the second guide plates 14 and the second guide plates 14 once during one construction. If the type of the "H"-shaped steel changes during the next construction, it is only necessary to adjust it again, which has a wide range of applications.

[0032] like Figure 1 and Figure 2 As shown, after the crane inserts the "H"-shaped steel from the inner side of the movable plate 1 into the cement soil, since the first support plate 6 is arranged on the upper side of the movable plate 1, the first support plate 6 is threadedly connected with the first threaded rod 7, and the first threaded rod 7 is rotatably connected with the first guide plate 8, the two first threaded rods 7 are rotated, and the first threaded rod 7 will move with the first guide plate 8, so that the first pulleys 9 inside the two first guide plates 8 are closely fitted with the side of the "H"-shaped steel, and in addition, the first limiting rod 10 is fixedly connected to the outer side of the first guide plate 8, and the first limiting rod 10 is slidably connected to the connecting plate on the lower side of the movable plate 1, and the first limiting rod 10 limits the first guide plate 8 to prevent the first guide plate 8 from tilting;

[0033] like Figure 3 and Figure 4 As shown, since the second threaded rod 13 is threadedly connected to the movable plate 1, and the second threaded rod 13 is rotatably connected to the second guide plate 14, the two second threaded rods 13 are rotated, and the second threaded rods 13 will move with the second guide plate 14, so that the second pulleys 15 inside the two second guide plates 14 are tightly fitted with the side of the "H"-shaped steel. In addition, the outer side of the second guide plate 14 is fixedly connected with a second limiting rod 16, and the second limiting rod 16 is slidably connected to the connecting plate on the lower side of the movable plate 1. The second limiting rod 16 limits the second guide plate 14 to prevent the first guide plate 8 from tilting. At this time, the "H"-shaped steel will be vertically inserted into the cement pit;

[0034] like Figure 1 As shown, when it is necessary to insert the "H"-shaped steel into other positions in the cement pit, it is only necessary to move the movable plate 1, and monitor the first level detector 11 and the second level detector 17 through the first alarm 12 and the second alarm 18 to observe in which direction the movable plate 1 is tilted, and adjust it to ensure that the "H"-shaped steel is vertically inserted into the cement pit to play a guiding role.
