Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0017] The present application will be further described in detail below in combination with the embodiments.
[0018] As Figures 1-4 shown, the device for preventing pile position deviation of the cement soil pipe pile provided by the present application has the following specific embodiments:
[0019] The device for preventing deviation of pile position of cement-soil inserted pipe pile comprises a stabilizing base 1, an outer casing 2 and an inner casing 3, the stabilizing base 1 is provided with a mounting hole 4, the upper end of the outer casing 2 is mounted on the mounting hole 4 of the stabilizing base 1 by welding, the outer diameter of the inner casing 3 is smaller than the inner diameter of the outer casing 2, the inner casing 3 is located in the outer casing 2 and coaxial with the outer casing 2, the upper end of the inner casing 3 is flush with the upper end of the outer casing 2, a plurality of connecting rib plates 9 are welded between the outer wall of the inner casing 3 and the inner wall of the outer casing 2, at least two flow discharge square holes 5 are formed in the wall of the inner casing 3 and the wall of the outer casing 2, the two flow discharge square holes 5 on the wall of the inner casing 3 are symmetrically arranged, the two flow discharge square holes 5 on the wall of the outer casing 2 are symmetrically arranged, and the flow discharge square holes 5 are arranged to ensure that the mud can flow out smoothly and reduce the resistance in the sinking process of the pipe pile.
[0020] As shown in Figure 2 The stabilizing base 1 is welded by a plurality of I-shaped steel 6, a steel plate strip 7 is welded between the two adjacent parallel I-shaped steels 6, a plurality of lifting hooks 8 are welded on the stabilizing base 1, the lifting hooks 8 facilitate the lifting device, the inner casing 3 and the outer casing 2 are both made of 20mm thick steel plate. The outer diameter and length of the inner casing 3 are 50cm and 3m respectively, and the outer diameter and length of the outer casing 2 are 80cm and 2m respectively.
[0021] The device for preventing deviation of pile position of cement-soil inserted pipe pile in the embodiment mainly ensures the perpendicularity and sinking of the pipe pile in construction, and the specific use steps are as follows:
[0022] (1) Before using the device, the site needs to be prepared and leveled to ensure that the operation area is suitable for the operation of mechanical equipment;
[0023] (2) Before drilling, the device is first pre-buried, and the flatness of the stabilizing base 1 is checked by using a level to ensure that it is horizontal. This step is to provide a stable guiding environment for the subsequent sinking of the pipe pile.
[0024] (3) The device is correctly installed at the predetermined position according to the design requirements, and it is ensured that the four flow discharge square holes 5 symmetrically arranged on the inner casing 3 and the outer casing 2 are unobstructed, so that the mud can flow out in time and the pressure balance is maintained;
[0025] (4) The prepared pipe pile is lifted, the pipe pile is accurately positioned by the guiding effect of the device, and it is ensured that the pipe pile is vertical and located on the correct axis. The perpendicularity of the pipe pile can be observed and adjusted by using two line sinkers with different angles;
[0026] (5) When the position and perpendicularity of the pipe pile are adjusted to meet the requirements, the vibration hammer is used for vibration sinking. In this process, the device plays a key role in helping to maintain the perpendicularity of the pipe pile and prevent deviation;
[0027] (6) During the sinking of the pipe pile, the verticality and position of the pipe pile are continuously monitored. If deviation is found, the operation should be stopped immediately, the position and verticality of the pipe pile should be adjusted, and then the sinking is continued; when the pipe pile reaches the predetermined design elevation, the vibration sinking is stopped, the device is removed, and the construction of the next pipe pile or the next step is prepared.
[0028] Through the above steps, the device can effectively ensure the quality of the pipe pile construction, and ensure that each pipe pile can be accurately sunk into the ground with correct verticality and position.
