Description
Technical field
This utility model belongs to construction technology of manual digging pile field, particularly to a kind of caisson.
Background technology
Caisson refers at engineering site by means shapes in foundation soil such as machine drilling, steel pipe soil compactions or manpower excavation
Become stake holes, and within it place steel reinforcement cage, concrete perfusion and the stake made, because industrial expansion and the growth of population,
Skyscraper is continuously increased, but the foundation condition being because a lot of city is poor, it is impossible to directly bears and is passed by skyscraper
The pressure come, earth's surface exists below the biggest weak soil of thickness or this drift sand formation, builds skyscraper as the most general in still continued to use
Friction pile, necessarily lead to the biggest sedimentation.
At the construction field (site), need to carry out the position of borehole is pinpointed, the building operation such as borehole, pipeline detection time just need
Whether there is drift sand formation to be analyzed underground, but owing to not knowing subsurface picture, conventional method is that explosion is excavated.But use
The method can not well control the quality problems of caisson in work progress.
Utility model content
The purpose of this utility model is: for the problem of above-mentioned existence, and this utility model provides a kind of caisson, this
Utility model simple in construction, easy to process, speed of application speeds, and reduces the danger in work progress, it is ensured that the skill of pile foundation
Art quality, this utility model is added with filter course simultaneously, has the effect of filtration.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of caisson, including retaining wall, described retaining wall is made up of several retaining wall unit spliceds, and each retaining wall unit all wraps
Including tension rib and concrete layer, described concrete layer waters outside tension rib, is also filled with filter course in described concrete layer.
Preferred: described filter course is arranged at outside tension rib.
Preferred: described filter course is one or more in Caulis et Folium Oryzae, straw and woven bag.
Preferred: the thickness of described filter course is 1-10mm.
Preferred: a diameter of 8mm of described tension rib.
Preferred: the lap of splice >=50mm between described retaining wall unit.
Preferred: the height of first segment retaining wall unit exceeds ground level 250mm.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, during borehole, it is to avoid can not run into drift sand, this utility model was provided with in the outside of tension rib
Filtering layer, is filled with one or more in Caulis et Folium Oryzae, straw and woven bag, Caulis et Folium Oryzae, straw and woven bag and all has in filter course
Water is every husky effect.
2, this utility model simple in construction, easy to process, speed of application speeds, and reduces the danger in work progress,
Ensure the technical quality of pile foundation.
3, this utility model low cost, this utility model energy-conserving and environment-protective.
4, this utility model is easy to use, quick, can effectively provide work task efficiency.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model；
1-retaining wall in figure；2-tension rib；3-arrangement of reinforcement；4-retaining wall unit；5-filter course；6-concrete layer.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail, in the most all accompanying drawings
Identical label represents same or similar parts, and the accompanying drawing in description is reduced form, is intended for understanding of the present utility model
Concrete structure.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit this practicality
Novel protection domain.
As it is shown in figure 1, a kind of caisson, including retaining wall 1, retaining wall 1 is made up of the splicing of several retaining wall unit 4, Mei Gehu
Wall unit 4 all includes tension rib 2, arrangement of reinforcement 3 concrete layer 6, and tension rib 2 is fixed-type with arrangement of reinforcement 3, and concrete layer 6 waters in drawing
Outside knot muscle 2, in described concrete layer 6, it is also filled with filter course 5.
Filter course 5 is arranged at outside tension rib 2, and filter course 5 has the effect of closure, drainage.
Filter course 5 can select to use Caulis et Folium Oryzae, and Caulis et Folium Oryzae can filter out some impurity, is good filtering material, it is also possible to
Select straw or woven bag as filtering material.
The thickness of filter course 5 is 8mm.
A diameter of 8mm of tension rib 2, shapes to retaining wall 1, reinforces the structure of caisson.
Between retaining wall unit 4, the lap of splice is 60mm.
The height of first segment retaining wall unit 4 exceeds ground level 250mm.
Based on above-mentioned technical scheme, the construction method of this caisson is:
Arranging 8 mouthfuls of dewatering wells in pile foundation construction coverage, the dewatering well degree of depth, less than absolute altitude about 5m at the bottom of stake, is used for dropping
Water level in low caisson, the most on construction ground in squeeze into the first segment retaining wall unit 4 of caisson, first segment retaining wall unit 4 is high
Going out ground level 250mm, stake position axis and elevation are demarcated suitable for reading at first segment retaining wall unit 4, when caisson enter into mud and
When fine sand, silty sand ground, layer overlay Caulis et Folium Oryzae, woven bag or straw outside the tension rib 2 of caisson, by dado template with
Tension rib 2 constitutes concrete layer 6, then is imported as early as possible by the concrete being stirred, and concrete vibrating is closely knit, retaining wall 1 concrete
Interior addition accelerator, accelerates concrete setting speed, reduces flowing water and washes away retaining wall 1 spillage and hole phenomenon caused, works as coagulation
After soil solidification is solid, dismantles dado template, then proceed to squeeze into caisson, dado template is being installed, repeat the above steps, until
Through poor strata.
