Abstract

The utility model provides a square concrete tubular pile. The square concrete tubular pile comprises a pipe wall composed of an outer surface and an inner surface, wherein two symmetrical support blocks are arranged on the two sides of the outer surface of the bottom of the pipe wall, the support blocks and the outer surface of the pipe wall are integrated, a plurality of air holes are formed in the top of the pipe wall, the air holes penetrate through the entire pipe wall, a plurality of drain holes are formed in positions 1 cm higher than the bottom of the pipe wall, and the drain holes penetrate through the entire pipe wall. The square concrete tubular pile provided by the utility model has the benefits that the support blocks are arranged on the outer surface of the pipe wall so as to enable the tubular pile to have greater bearing capability, in addition, the arranged air holes and drain holes enables air and ponding water to be discharged, and the phenomena of pile cap damage and land uplift can be avoided.

Description

A kind of square concrete pile tube
Technical field
The utility model belongs to building foundation engineering field, especially relates to a kind of square concrete pile tube.
Background technology
Concrete tubular pile is because its supporting capacity is high, applied widely, easy construction, and the good technical performance such as pile quality is reliable, had obtained fast development in recent years.Most of concrete tubular piles are linear pattern, and the frictional force between the soil body is less, when needs meet larger bearing capacity, often need to increase length or the quantity of pile tube, this can increase the cost of whole engineering, and most pile tubes are without drain hole and pore, and ponding and gas cannot be got rid of in time, in piling process, easily there is the phenomenons such as earth heaving and stake top damage.
Utility model content
The purpose of this utility model is to provide a kind of square concrete pile tube.
The technical solution of the utility model is: a kind of square concrete pile tube, comprise the tube wall being formed by external surface and inner surface, the external surface both sides of described tube wall bottom are provided with two symmetrical back-up blocks, the external surface of described back-up block and tube wall is structure as a whole, described tube wall top is provided with some pores, described pore connects whole tube wall, and described tube wall bottom 1m is provided with some drain holes above, and described drain hole connects whole tube wall.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, outer surface of tube wall arranges back-up block makes pile tube have larger supporting capacity, the pore simultaneously arranging and drain hole can be discharged the gas in pile tube and ponding in time, avoid occurring that stake top is damaged and the phenomenon of earth heaving.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model.
In figure:
1, external surface 2, inner surface 3, tube wall
4, back-up block 5, pore 6, drain hole
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1-2, a kind of square concrete pile tube of the utility model, comprise the tube wall 3 being formed by external surface 1 and inner surface 2, external surface 1 both sides of described tube wall 3 bottoms are provided with two symmetrical back-up blocks 4, described back-up block 4 is structure as a whole with the external surface 1 of tube wall 3, and described tube wall 3 tops are provided with some pores 5, and described pore 5 connects whole tube wall 3, described tube wall 3 bottom 1m are provided with some drain holes 6 above, and described drain hole 6 connects whole tube wall 3.
The course of work of this example: a kind of square concrete pile tube, the back-up block 4 that external surface 1 both sides of tube wall 3 arrange is strengthened its supporting capacity greatly, simultaneously in piling process, gas is released out by pore 5 in the way of rising, and be unlikely to pressure, make too greatly the infringement of stake top,, if there is water to enter pile tube, can flow out along drain hole 6 meanwhile, thereby avoid occurring the phenomenon of earth heaving.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
