Abstract

The utility model discloses bored pile casing in a kind of water, in this water, bored pile comprises large casing and little casing with casing, described little casing is positioned at large casing inside and both are in the same center line, between described large casing and little casing, be provided with backfill clay, the length of described little casing is greater than the length of large casing.In this water, the large little casing of casing embedded set in casing for bored pile, successively extracts little casing and large casing after pile, has realized the recycling of casing, has saved construction cost; Two casing construction parties have been avoided the quality accident such as mud loss, collapse hole bury drills, have reduced pile risk, have improved pile quality.In water, bored pile double pile casing construction economy benefit is obvious, and constructing operation is convenient, and pile quality is high.

Description

Bored pile casing in a kind of water
Technical field
The utility model relates to bored pile casing in a kind of water.
Background technology
In water, bored pile construction mainly adopts full casing method at present, and casing can not be recycled, and causes bored pile construction cost in water to increase, and profundal zone bored pile cost increases particularly evident.
Summary of the invention
The technical problems to be solved in the utility model is to provide bored pile casing in a kind of water that can reclaim from construction environment.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: in this water, bored pile comprises large casing and little casing with casing, described little casing is positioned at large casing inside and both are in the same center line, between described large casing and little casing, be provided with backfill clay, the length of described little casing is greater than the length of large casing.
The utility model adopts after technique scheme: the large little casing of casing embedded set in casing for bored pile in this water, after pile, successively extract little casing and large casing, and realize the recycling of casing, save construction cost; Two casing construction parties have been avoided the quality accident such as mud loss, collapse hole bury drills, have reduced pile risk, have improved pile quality.In water, bored pile double pile casing construction economy benefit is obvious, and constructing operation is convenient, and pile quality is high.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is further described in detail.
Fig. 1 is use schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, in this water, bored pile comprises large casing 1 and little casing 2 with casing, described little casing is positioned at large casing inside and both are in the same center line, and between described large casing and little casing, is provided with backfill clay 3, and the length of described little casing is greater than the length of large casing.
When use, first in water, set up working platform, utilize leading truck that large casing is transferred to riverbed and adopted vibrating hammer vibration hammering to make large casing sink to certain buried depth, the water in large casing is taken out to backfill clay compacting in large casing.Then little casing sinks to by vibrating hammer hammering, and little casing must pass the back fill course in large casing, and than more than the super dark 0.5m of large casing, little casing exceeds large casing 0.5m, in order to mud circulation.After soil layer in the middle of little casing is cleaned out; under the protection of little casing, can complete smoothly pore-forming, underwater concreting; due to rich and influential family by and little casing between backfill clay, before concrete initial set, little casing can be pulled out, and there will not be the quality problems such as collapse hole, necking down.Concrete completes setting and harden in large casing and backfill clay, wait pile strength reach design strength 75% after, owing to there being the isolation of backfill, large casing also can be pulled out smoothly.
