Description

Technical Field

[0001] This utility model relates to the field of SMW method pile steel positioning technology, and in particular to an SMW method pile steel positioning clamp. Background Technology

[0002] The SMW method involves using a multi-axis drilling and mixing machine to drill to a certain depth on site, while simultaneously spraying a cement-based reinforcing agent at the drill bit to repeatedly mix with the foundation soil. Overlapping construction is adopted between each construction unit. Before the cement-soil mixture hardens, H-beams or steel plates are inserted as stress reinforcement materials. Once the cement hardens, a continuous, complete, and seamless underground wall with a certain strength and rigidity is formed.

[0003] In existing technologies, when steel sections are inserted into cement-soil mixing piles, the construction accuracy and reliability cannot be guaranteed by relying on the adjustments made by construction personnel. The uneven distances between the steel sections can easily lead to steel section skew, affecting the overall quality and reliability, and also resulting in an unsightly appearance.

[0020] Reference Figure 1-3A SMW method pile steel positioning clamp includes a foundation 1 and a steel section 2. Cement-soil mixing piles 5 are provided on the foundation 1. Multiple sets of cement-soil mixing piles 5 are arranged in an array on the foundation 1. The steel section 2 is arranged correspondingly to the cement-soil mixing piles 5. Before the cement-soil mixing piles 5 solidify and harden, the steel section 2 is embedded into the upper part of the cement-soil mixing piles 5.

[0021] The upper side of the steel section 2 is provided with a positioning device 4, which is used to effectively ensure the standard spacing between the steel sections during construction and also plays an aesthetic role. The positioning device 4 includes a reinforcing bar 41 and a positioning steel plate 43. The upper side of the positioning steel plate 43 is fixedly connected to the reinforcing bar 41. Multiple sets of positioning steel plates 43 are provided and abut against the top two side walls of each steel section 2 to clamp the steel section 2. As needed, wooden boards or patches can be used to fill the gaps to ensure stable clamping. The reinforcing bar 41 is provided with a connecting sleeve 42. The reinforcing bar 41 and the connecting sleeve 42 are connected by threads. By rotating the connecting sleeve 42, the distance between the reinforcing bars 41 can be adjusted. Multiple reinforcing bars 41 can be connected to ensure that the top of each steel section 2 can be stably restricted to avoid shaking or displacement, which would affect the insertion of the steel section 2.

[0022] A laser locator 3 is installed on the foundation 1. It plays a positioning role when the steel section 2 is about to be inserted into the cement-soil mixing pile 5. The laser locator 3 includes a housing 30, a slide rail 32 and a laser spotlight 34. The bottom of the housing 30 is provided with a rod 31. The rod 31 is inserted into the foundation 1 to facilitate fixing the laser locator 3. The slide rail 32 is provided with a lamp holder 33. The laser spotlight 34 is connected to the lamp holder 33. A locking device is provided on one side of the lamp holder 33. The lamp holder 33 slides on the slide rail 32 to adjust its position and is then fixed and locked by the locking device.

[0023] The slide rail 32 is located on the side of the housing 30 near the steel section 2. The laser spotlight 34 is connected to the lamp holder 33 by a ball joint, which facilitates fine-tuning of the angle and ensures that the laser spotlight 34 projects a laser beam in a straight line, which is convenient for positioning the bottom of the steel section 2. The slide rail 32 is provided with limit screws 321 at both ends to prevent the lamp holder 33 from falling off the slide rail 32, or to facilitate the removal of the lamp holder 33 and the laser spotlight 34 after construction for recycling and cleaning, thus improving transportation convenience. The slide rail 32 is provided with negative electrode contact pieces and positive electrode contact pieces on the upper and lower sides, respectively. A power supply line 35 is provided on one side of the housing 30.

The power supply line 35 is connected to the laser spotlight 34 to complete the power supply. Alternatively, the laser spotlight 34 can be directly connected with a wire. The wire is wound in a spiral shape for easy movement and adjustment of the laser spotlight 34, and easy to store and organize.

[0025] In this embodiment, after the cement-soil mixing pile 5 is processed, the laser locator 3 is installed. According to the design position, the position of the lamp holder 33 is adjusted and locked. The laser spotlight 34 is turned on to project the cursor. The construction personnel use a hoist to lift the steel section 2, use the cursor to locate the insertion position, and then press it down. At the same time, the positioning device 4 is locked on the top of the steel section 2 to ensure that the steel section 2 is accurately and reliably inserted into the cement-soil mixing pile 5. The positioning work is completed neatly and accurately, ensuring the standard spacing between the steel sections 2. After completion, the positioning device 4 and the laser locator 3 are removed or adjusted for subsequent insertion of the steel section 2.
