Include reinforcing pile vertical at the weak soil in situ, the lateral separation setting, each reinforcing pile's lower extreme and the drill bit fixed connection who is located the basement rock, the upper end flushes with weak soil layer surface, reinforcing pile, the outer cladding sack of drill bit lateral wall, weak soil layer surface with fill physically between be provided with the bed course.
Description
Technical field
The utility model relates to geotechnical engineering, particularly Rock covers the Base Consolidation Engineering of weak soil.
Background technology
There is the ground many basement rock covering weak soil in western mountainous areas, when building embankment engineering on this ground, needing to carry out consolidation process to weak soil.When basement rock covering weak soil condition and being poor, during as the weak soil more for muddy soft soil, Muddy Bottoms peat soil and organic content, traditional reinforcement of soft soil treatment measures such as cement mixing method, high-pressure rotary jet grouting pile, CFG stake etc. all can not be suitable for, and its bottom application work under cover basement rock time, basement rock can not be entered and stablize pile body; If adopt current bored pile, then construction investment is huge.Therefore, need that a kind of consolidation effect is good in the case, economy, easy construction special soft soil ground stabilization measure, and meet environmental requirement.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of drill bit anchor pile composite foundation stabilization structure, stably can arrange reinforcing pile in Soft Soil Layer, effectively solves reinforcing difficult problem basement rock covering soft foundation.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Drill bit anchor pile composite foundation stabilization structure of the present utility model, is included in reinforcing pile that is longitudinal in Soft Soil Layer, that be horizontally arranged at interval, it is characterized in that: the lower end of described each reinforcing pile is fixedly connected with the drill bit being positioned at basement rock, and upper end flushes with Soft Soil Layer surface; Reinforcing pile, drill bit sidewall outer cladding cloth bag; Bed course is provided with between Soft Soil Layer surface and filling body.
The beneficial effects of the utility model are, utilize drill bit anchoring type pile body to reinforce on basement rock and cover weak soil, traditional ground reinforcement measure can be solved and in special soft soil, pile and reinforcing pile can not can not enter the problem in basement rock at the bottom of spud pile, simple, the good economy performance of this structure construction, has wide popularizing application prospect simultaneously.
Accompanying drawing explanation
This manual comprises following three width accompanying drawings:
Fig. 1 is the sectional schematic diagram of the utility model drill bit anchor pile composite foundation stabilization structure;
Fig. 2 is the construction schematic cross-section of the utility model drill bit anchor pile composite foundation stabilization structure;
Fig. 3 is the drill bit signal drawing of the utility model drill bit anchor pile composite foundation stabilization structure.
Component shown in figure, toponym and corresponding mark: drill bit 10, reinforcing bar 11, sleeve pipe 20, cloth bag 30, drilling rod 40, reinforcing pile body 50, bed course 60, basement rock A, weak soil B, filling body C.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, drill bit anchor pile composite foundation stabilization structure of the present utility model, be included in the reinforcing pile 50 that Soft Soil Layer B is longitudinal, be horizontally arranged at interval, it is characterized in that: the lower end of described each reinforcing pile 50 is fixedly connected with the drill bit 10 being positioned at basement rock A, and upper end flushes with Soft Soil Layer B surface; Reinforcing pile 50, drill bit 10 sidewall outer cladding cloth bag 30; Bed course 60 is provided with between Soft Soil Layer B surface and filling body C.The degree of depth that described drill bit 10 enters basement rock is not less than 30cm usually, and its upper end is on basement rock A scar.With reference to Fig. 3, the top of described drill bit 10 is fixedly installed reinforcing bar 11, and this reinforcing bar 11 extends in reinforcing pile 50.
With reference to Fig. 2 and Fig. 3, the external wall of upper portion of described drill bit 10 has and forms with sleeve pipe 20 interface be threaded, and then has the interface forming cutting ferrule with drilling rod 40 and be connected in the middle part of its end.During construction, sleeve pipe 20 lower end is threaded with drill bit 10, and top flushes ground basal plane, and cloth bag 30 is arranged on sleeve pipe 20 inner, and lower end outsourcing drill bit 10 is also fixedly connected with it.Drilling rod 40 lower end adopts cutting ferrule to be connected with drill bit 10, and after drill bit 10 pierces down and covers basement rock A, drilling rod 40 pine cover takes out.Sleeve pipe 20 adopts PVC usually.Reinforcing pile 50, adopt concrete mixture to make, vibration pours in cloth bag 30 and forms stressed pile body.
The utility model utilizes drill bit 10 to pierce down to cover in basement rock A, as the fixed end of reinforcing pile 50, reinforcing pile 50 and drill bit 10 can be made to form a fixed connection by exposure reinforcing bar 11.Retaining wall before utilizing sleeve pipe 20 to construct in weak soil B as reinforcing pile body 50, and fixing cloth bag 30, it can take out recycling.Utilize cloth bag 30 as reinforcing pile body 50 pile bag, and be convenient to sleeve pipe 20 and extract out in the work progress of reinforcing pile 50 and do not affect pile.Bed course 60 is utilized to fill out the buffering cooperation layer of body C as the composite foundation and top of reinforcing pile body 50 formation.This structure effectively solves base reinforcement measure traditionally pile and reinforcing pile can not can not enter the problem in basement rock at the bottom of spud pile in special soft soil, and simple, the good economy performance of this structure construction, has wide popularizing application prospect simultaneously.
Sleeve pipe 20 internal diameter is determined according to design stake footpath, and its wall thickness can resist the soil pressure bottom Soft Soil Layer B, and it is connected rear easy disengagement with drill bit 10.Cloth bag 30 deployment diameter meets the diametric requirements of design reinforcement stake 50.Described reinforcing pile 50 setting space and diameter meet design requirement, and diameter is generally 0.4 ~ 0.6m, and setting space is generally 1.4 ~ 1.6m.
See figures.1.and.2, the construction sequence of drill bit anchor pile composite foundation stabilization structure of the present utility model is as follows:
Sleeve pipe 20 and cloth bag 30 are socketed;
Sleeve pipe 20 is connected with drill bit 10;
Drill bit 10 is connected with drilling rod 40
Vertical press-in connector makes it enter in Soft Soil Layer B to basement rock A end face;
Start drilling rod 40, drill bit 10 is pierced in basement rock A fixing;
Sleeve pipe 20 and drill bit 10 are thrown off;
Drilling rod 40 overlaps with drill bit 10 pine and takes out drilling rod 40;
Segmentation penetration concrete compound in cloth bag 30, concrete perfusion compound limit, limit promotes sleeve pipe 20;
Construction cushion coat 60 after reinforcing pile 50 is formed and reaches design strength;
Construction filling body C.
Some principles of the above the utility model drill bit anchor pile composite foundation stabilization structure that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
