Special-shaped concrete pipe

A concrete pipe pile and special-shaped technology, which is applied in the direction of sheet pile walls, buildings, and foundation structure engineering, can solve the problems of collapsed holes, high cost of semi-rigid pile-soil composite foundation, and affecting the quality of the foundation, so as to increase the surface area and increase the quality of the foundation. Large bearing capacity and the effect of reducing the amount of concrete

Problems solved by technology

Prefabricating the hole first and then pouring concrete into the hole is more likely to cause hole collapse or necking to affect the quality of the foundation than the latter method, and the latter method is more expensive to prepare a semi-rigid pile-soil composite foundation

Embodiment 1

[0015] like figure 1 , 2 As shown, a special-shaped concrete pipe pile includes a central hole 2 arranged coaxially with the pile body 1 , and end plates 3 arranged at both ends of the pile body 1 .

[0016] still as figure 1 , 2 As shown, grooves 4 are coaxially arranged on the pile body 1 between the end plates 3 . like figure 2 As shown, the cross section of the pile body is rectangular, the cross section of the groove 4 is semicircular, and the groove 4 is symmetrically arranged on the surrounding surface of the pile body 1 .

[0017] like figure 1 , 2 As shown, a grouting hole 5 is coaxially arranged on one side of the central hole 2 of the pile body 1 .

Embodiment 2

[0019] like image 3 As shown, a special-shaped concrete pipe pile includes a central hole 2 arranged coaxially with the pile body 1, and a groove 4 is arranged coaxially on the pile body 1, and the groove 4 is symmetrically arranged on the surrounding surface of the pile body 1.

[0020] All the other implementations are as in Example 1.

Abstract

The invention discloses an anomalous concrete tubular pile comprising a centre bore coaxially arranged with the pile shaft and end boards arranged at the two ends of the pile shaft, which is characterized in that the pile shaft positioned between the end boards is coaxially provided with a groove, and the transect of the groove is in semicircular shape, V-shape or U-shape, which are symmetrically or equally arranged around the pile shaft. The anomalous concrete tubular pile not only can be used for semi-rigid pile-soil composite foundation but also can be driven into soil as rigid pile; the tubular pile has the advantages of large superficial area, strong bearing capacity, and small use amount of concrete, and is particularly suitable for the geology of coastal areas and the Yellow River flood plain areas.

Description

Technical field: [0001] The invention relates to pile foundation engineering technology in the construction field, in particular to prestressed concrete special-shaped pipe piles. Background technique: [0002] Prestressed high-strength concrete pipe piles are widely used in the construction of houses, roads, bridges and other projects due to their superior performance. Its main function is that it can be mechanically driven into the hard rock formation underground like a nail, and can better support the weight of large buildings such as houses and bridges. For coastal areas\or flooded plains, rigid piles are generally used to build small high-rise residences with about 12 floors, and the more economical and reasonable one is semi-rigid pile-soil composite foundation (to save foundation cost), that is, cement and soil are passed through mechanical Stir to form cement, and then insert the column or tube into it, and when it is semi-solidified, pull out the column or tube, an...
