Problems solved by technology

However, due to the fact that there is an included angle α greater than 90° and less than 135° on both sides of the first wing plate and web plate of this structure, in practical applications, the stress here is relatively concentrated. In addition, the T-shaped piles of the above structure are There is no tongue and groove, resulting in large gaps between piles, and poor water and soil stopping effects

Embodiment Construction

[0027] Such as figure 1 , figure 2 As shown, the pile is T-shaped by the first panel 1 and the web 2, and there is a gradual transition between the panel and the rib, and there are two types of bevel transition and arc transition at the corner transition, and in the first panel 1 The wings have tongue and groove. figure 2 The shape of the T-shaped pile shown is also similar to the shape of "I", and the other end of the web 2 is connected to the second panel 3 . The lower ends of the first panel 1 and the web 2 are respectively formed with oblique cutting edges 4 with the same inclination direction, which can generate passive earth pressure to squeeze adjacent piles together during piling.

[0028] image 3 , Figure 4 It is a "T"-shaped pile, and the two ends of the panel are flat tenon and tongue-and-groove, and the slight difference is image 3 The corner transitions of are beveled, Figure 4 The corners of are arcs.

Abstract

The invention relates to a grooved bank protection T-shaped pile. The invention aims to solve a technical problem of providing the grooved bank protection T-shaped pile with simple structure, strong stability and good water-soil stop effects, so as to improve the effect of treating gaps between adjacent pile bodies and reduce the material amount of bank protection retaining walls. The technical proposal for solving the problem is as follows: the grooved bank protection T-shaped pile is characterized in that the pile is in a T shape formed by a first panel and a web plate; the panel and a ribbed slab are in gradual change transition; and two wings of the first panel are provided with grooves. The T-shaped pile can be used for constructing river bank protections, wharf bases and ribbed-structure thin diaphragm wall retaining walls.

Description

technical field [0001] The invention relates to a T-shaped pile, in particular to a revetment T-shaped pile with a tongue-and-groove opening. It is suitable for constructing river revetment and wharf foundation, and it can also construct thin-walled underground diaphragm wall retaining wall with rib structure. Background technique [0002] At present, it is more common to use rectangular section concrete sheet piles as technical measures for river bank revetment and enclosure engineering, but it is well known that the moment of inertia of rectangular section is much smaller than that of T-shaped section with equal cross-sectional area, so the bending resistance of rectangular sheet piles is not as good as that of equal cross-sectional area. T-shaped piles. For the above-mentioned situation, some special-shaped piles have occurred successively, as the Chinese utility model patent that the patent number is 200720108572.7 discloses a kind of "prefabricated reinforced concrete ...
