Abstract
The utility model provides the foundation structure of directly processing on bury, this structure is the filling filling bag that is equipped with successively woven cloth, seepage material, band drain on bury, lays bar shaped on band drain, then in filling filling bag, lays the foundation structure that simple and easy sleeper and light rail form disposable processing.Foundation structure described in the utility model can once insert the longitudinal drainage plate about 35m length in bury; And carry out various precompressed ways according to engineering characteristic, this structure being when forming board-plugging device traveling condition taken a little materials and time, but with general wait bury form surperficial crust layer or other way compare can save time approximately 25%, manpower approximately 15%, energy consumption and expense approximately 30%.
Description
Technical field
The utility model relates to a kind of foundation treatment engineering technology, particularly a kind of foundation structure of directly processing on bury.Possession base is processed field of engineering technology.
Background technology
At present, on bury (w=85～100% left and right), carry out foundation treatment engineering, the method of processing has multiple, but be mainly to manage to insert vertical drainage passage in bury, general with band drain, on band drain, apply again prepressing materials or vacuum preloading or combined vacuum and surcharge preloading, moisture in bury is discharged outside bury by each drainage channel, reduce the water content of bury, thereby improve the characteristic load bearing capacity of bury, reduce the compressibilty of bury, reduce the settling amount of building from now on, improve the physico mechanical characteristic of hydraulic-filled soft clay, reach the safety of each building of construction thereon.But that above-mentioned method for processing foundation exists is time-consuming, expensive, the defect of power consumption etc.
Conventionally in order to insert band drain in bury, needing to wait for that bury has certain intensity, can walk pedestrian and carry out the work of board-plugging device plate, approximately needed for two years, is in order to allow bury natural air drying, forms a crust layer, then carries out ground processing; Although also have now directly discharging type vacuum prepressing consolidation of soft clay foundation technology, it can reduce the stand-by period, process the degree of depth of bury in the long left and right of 5m, and need carry out a Soft Ground Improved By Vacuum Preloading and process.When need processing bury thickness is greater than 5m, need carry out in weak soil, inserting band drain for the second time, carry out vacuum preloading for the second time.Inserting for the first time band drain and vacuum preloading is in order to make slightly intensity of bury top layer, form fast a crust layer, so that the machinery of long band drain is inserted in traveling, though make great progress but still time-consuming, power consumption and cost are still higher, insert band drain and twice vacuum preloading twice in bury because want.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of foundation structure of processing on bury, it can once set length at the band drain of about 35m and need carry out vacuum preloading or piling prepressing or combined vacuum and surcharge preloading, can raising work effect, energy-conserving and environment-protective, reduction construction costs.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of foundation structure of directly processing on bury of the present utility model, this structure has been laid on bury, wherein: this structure is on bury, to be equipped with successively woven cloth, impervious material layer, band drain, filling bag, and easy sleeper and light rail be installed successively thereon, form the foundation structure of disposable processing, directly on bury, insert longitudinal drainage plate.
Foundation structure described in the utility model utilization can once insert the band drain about 35m length in bury; Vacuum preloading or piling prepressing, or combined vacuum and surcharge preloading.This structure taken a little materials and artificial when forming hard pavement, but compare manpower, time, material, energy consumption and the expense of can saving with the secondary vacuum precompressed of secondary-plug band drain or combined vacuum and surcharge preloading, is more environmental protection.
Accompanying drawing explanation
Fig. 1 is the foundation structure plan view of directly processing on bury of the present utility model.
In Fig. 1:
1. longitudinal drainage plate 2. seepage material layer 3. woven cloth 4. filling bag
5. transverse drainage plate 6. sleeper 7. light rails
The specific embodiment
By reference to the accompanying drawings the foundation structure of directly processing at bury of the present utility model is illustrated.
As shown in Figure 1, the foundation structure directly carrying out on bury of the present utility model, this structure is the filling bag 4 that is equipped with according to this seepage material layer 2, base fabric 3, transverse drainage plate 5 on bury, is equipped with one or more layers bar shaped on transverse drainage plate 5, when if filling bag is multilayer, interlayer need spread transverse drainage plate 5, simple and easy sleeper 6 and light rail 7 are installed in filling bag 4 according to this, are formed the foundation structure of disposable processing, directly on bury, insert longitudinal drainage plate.
The length of described longitudinal drainage plate 1, at 35m, can be carried out the processing of precompressed ground.
The foundation structure directly carrying out on bury of the present utility model, its function is achieved like this;
The foundation structure directly carrying out on bury of the present utility model, on existing bury, be equipped with seepage material layer 2, on lay according to this base fabric 3 and transverse drainage plate 5, on transverse drainage plate 5, be equipped with the filling bag 4 of one or more layers bar shaped, when if filling bag is multilayer, interlayer need spread transverse drainage plate 5.Under these load effects, the characteristic load bearing capacity of bury is significantly improved, and forms so-called board-plugging device work plane, and the board-plugging device on can the simple and easy track of traveling.
After processing by said structure, can in filling bag, lay simple and easy sleeper 6 and light rail 7, form the foundation structure of disposable processing, and plate machinery is installed on light rail 7 and be constructed.
Plate machinery,, as sand wick etc. and carries out laterally by designing requirement, extending and spreading out to construction requirement to inserting the longitudinal drainage plate 1 of the long left and right of 35m or the vertical row water body of other infiltrations in bury by designing requirement according to this.
After row's longitudinal drainage plate 1 has entered, band drain machine moves forward by designing requirement along track, carries out second row longitudinal drainage plate 1 and inserts, and arranges at the most forward according to this, until all complete the area of base that needs processing.When board-plugging device moves forward, when falling short of, filling bag 4 can continue to lay filling bag.Can spreading light rail when light rail 7 falls short of, sleeper and light rail all can be reused.
After completing plate work, can carry out preloading, vacuum combined stack-load, vacuum preloading.
