Detailed Description

The present application is described in further detail below with reference to figures 1-6.

The embodiment of the application also discloses a building excavation foundation ditch supporting device. Referring to fig. 1, the supporting device for the foundation pit of the excavation of the building is set as a supporting pile, which mainly comprises a circular pipe pile 11 and flange plates 12 fixedly connected to two opposite sides of the circular pipe pile, wherein the fixed connection can be integrally arranged, and the circular pipe pile 11 and the flange plates 12 in the embodiment of the application are made of stainless steel, so that the circular pipe pile 11 and the flange plates 12 can be integrally formed.

In order to facilitate the staff to press the round pipe pile 11 into the soil layer, one end of the flange plate 12 and one side far away from the round pipe pile 11 are obliquely arranged, so that the section of the flange plate 12 along the length direction thereof forms a shape similar to a right trapezoid. In the embodiment of the present application, the circular tubular pile 11 and one end of the flange plate 12 on both sides of the circular tubular pile 11 form an approximate tip, which is convenient for a worker to apply force to the circular tubular pile 11.

Referring to fig. 1 and 2, in other embodiments, a first limiting groove 111 may be formed on one side of the flange plate 12 of each support pile, so as to ensure that the flange plate 12 of the adjacent support pile is clamped in the first limiting groove 111 during construction, thereby forming a limiting effect.

In other embodiments, the two flange plates 12 are located in two horizontal planes, and are located on two sides of the plane where the diameter of the support pile is located.

In other embodiments, referring to fig. 3, both flanges 12 are simultaneously in the same horizontal plane, both flanges 12 are simultaneously in the plane of the diameter of the support pile, referring to fig. 4, or are simultaneously in the plane of the chord of the support pile.

In other embodiments, referring to fig. 5 and 6, in the construction process, the circular pipe piles 11 are pressed one by one, the pile pressing direction is a vertical direction, and the length direction of the circular pipe piles 11 is a force application direction of workers; therefore, in order to further limit the relative position between two adjacent round pipe piles, a second limiting groove 121 is formed on one side of the flange plate 12.

In order to fit the second limiting groove 121, a limiting strip 122 is fixed at the second limiting groove 121 on the flange plate 121 on one side of the adjacent round pipe pile 11.

The side walls of the second limiting groove 121 are obliquely arranged, and the two side walls of the second limiting groove 121 gradually approach each other from the direction away from the flange plate 12 to the direction close to the flange plate 12; meanwhile, in order to facilitate the alignment of the position limiting strip 122 and the second position limiting groove 121 by the staff in the beginning, the flange plate 12 may be provided with a rounded corner at the end of the second position limiting groove 121.

In order to limit the relative position of two adjacent circular pipe piles in the vertical direction, a limiting block 123 can be further arranged in the second limiting groove 121, and the limiting block 123 can be integrally formed with the flange plate 12 or fixed in a welding mode or the like.

According to the requirement of a supporting area, in general, the position of the limiting block 123 is fixed and can be integrally formed; if the soil layer changes or the supporting depth requirement of the supporting area is different, the supporting area can be fixed by welding.

The implementation principle of the building excavation foundation pit supporting device in the embodiment of the application is as follows: the worker aligns the tip of the round pipe pile 31 to the position to be embedded, further determines whether the position of the flange plate 12 of the round pipe pile 31 is correct, and applies force if the position is correct to enable the round pipe pile 31 to finish pile sinking operation; if not, adjusting to the correct position.

When the staff carries out the pile pressing to adjacent pipe pile 11, need aim at the position that two adjacent pipe piles are close to one side flange plate 12 each other, with spacing strip 122 joint income second spacing inslot 121. And then forming a supporting area which is similar to a square ring, a circular ring or a building edge, thereby achieving the purpose of reducing the soil in the foundation pit.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
