Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a sleeve type joint pipe device for diagonal bracing piles in a foundation pit. Background Art

[0002] The inclined bracing piles in the foundation pit are generally composed of combined inclined piles extending under the foundation pit bottom plate and steel pipe inclined braces located above the foundation pit bottom plate; the upper end of the steel pipe inclined brace is pressed against the top beam through a jack preloading device, and the lower end of the steel pipe inclined brace is supported on the upper end of the combined inclined pile; the combined inclined pile is generally composed of a precast concrete square pile in the center and a cement soil pile wrapped on the outside.

[0003] During the construction of diagonal bracing piles in foundation pits using an integrated pile driver, the piles often reach an unusually low elevation due to the soft soil at their base. If the top of the diagonal bracing pile is set too high, it can easily collide with the crown beam (also known as the pressure beam) during excavation of the foundation trench, causing it to tilt and break. Therefore, a butt joint pipe, specifically a sleeve-type joint pipe, is required between the top of the diagonal bracing pile and the jack preload device.

[0004] Chinese utility model patent application number CN202321790902.0 discloses a sleeve-type joint pipe device for diagonal bracing piles in foundation pits. The device comprises an upper steel pipe section and a lower steel pipe section, each of which is smaller at the top and larger at the bottom, and fits together at the interface. The outer periphery of the connection between the upper and lower steel pipe sections is welded, and the lower end of the lower steel pipe section is welded to the upper end of the inserted steel pipe diagonal brace. A transverse steel pad is fixed to the top of the upper steel pipe section, and the upper end surface of the steel pipe diagonal brace is abutted against the bottom plane of the transverse steel pad. The lower steel pipe section is provided with multiple weld holes along its circumference, and the annular edge of each weld hole is welded to the upper end of the steel pipe diagonal brace. The weld holes are rectangular weld holes with a height greater than width, and multiple rectangular weld holes are located at the middle of the height of the lower steel pipe section. This sleeve-type joint pipe device ensures that the upper end of the steel pipe diagonal brace and the sleeve-type joint pipe are firmly and reliably connected. Even under high axial pressure, it will not yield or bulge, and can safely transmit the axial pressure transmitted by the foundation pit retaining pile row through the pressure beam.

[0005] In the above structure, the inclined support piles in the foundation pit cannot adjust the angle with the supporting piles, and only support the supporting piles at one angle. When the ground is uneven, the inclined support piles in the foundation pit cannot be placed flat and cannot provide sufficient support. Utility Model Content

[0006] The purpose of the utility model is to provide a sleeve-type joint pipe device for diagonal support piles in a foundation pit. The utility model can adjust the angle of the support rod through the hinged rotation of the first sleeve and the second sleeve to adapt to various placement environments.

The limiting grooves 106a are arranged along the length direction of the movable rod 106, and the spacing between adjacent limiting grooves 106a is equal.

[0070] To adjust the extended length of the movable rod 106, the operator rotates the rotating block 107b to separate the rotating block 107b from the thread in the abutment groove 105a, then pulls out the rotating block 107b, drives the insertion rod 107a to be pulled out of the through hole 105b, and then slides the movable rod 106 to adjust the extended length of the movable rod 106. After confirming the length, the insertion rod 107a is inserted into the through hole 105b, and the insertion rod 107a is embedded in the limiting groove 106a.
