Description
Technical field
It the utility model is related to a kind of Reinforcement of Soft Soil Subgrade structure.
Background technology
The purpose of soft soil roadbed processing is to improve the stability and bearing capacity of this section of highway subgrade.Soft soil roadbed place
The processing mode of sand bedding course, civil grille layer and piling prepressing, the consolidation effect of this processing mode is usually used in reason mode
It is less desirable.In addition, it can also install a campshed wall additional respectively in the both sides of highway subgrade sometimes.It is each per campshed wall by more along pre-
The spaced side stake composition in fixed direction (i.e. the length direction of highway subgrade), each side stake are former soft soil roadbed by the insertion of its lower end
It is interior and realize stationary positioned, and the upper end of each side stake is exposed, is easily pulled out former soft soil roadbed by external force and lost,
Make piling wall ineffective.
The content of the invention
The main purpose of the utility model is that provide it is a kind of can improve the soft soil roadbed of stability and bearing capacity plus
Fixing structure.
Above-mentioned purpose is achieved by the following technical solution：
A kind of Reinforcement of Soft Soil Subgrade structure, including：Pile layer, by more squeeze into it is soft soil roadbed in pile form；Bed course,
It is layed on soft soil roadbed；Civil grille layer, is layed on bed course；Metalling, is layed on civil grille layer；Pitch
Concrete pavement layer, is layed on metalling；Two rows of piling walls, are respectively arranged on the both sides of asphalt concrete pavement layer, per campshed
Wall includes more along the spaced side stake in predetermined direction, every side stake include lower end squeeze into it is soft soil roadbed in and upper end extension
Be connected to the pile body of asphalt concrete pavement layer and one end with pile body and the other end stretch into asphalt concrete pavement layer
One convex ribs.
The utility model soft soil roadbed to original can play reinforcement effect by increasing pile layer, improve stability and carrying
Ability；The first convex ribs in asphalt concrete pavement layer are stretched into by being set in the pile body of each side stake, can not only be mixed using pitch
Solidifying dirt road surface layer makees further fixation to reduce the risk that each side stake is lost to the stake of each side, while the first of each side stake is convex
Muscle can play asphalt concrete pavement layer booster action, the stability and bearing capacity of raising.
Brief description of the drawings
Fig. 1 shows the structure diagram of the utility model；
Fig. 2 shows the schematic diagram after each several part is decomposed on the basis of Fig. 1.
Drawing reference numeral：
10 is soft soil roadbed；
20 pile layers, 201 piles；
30 bed courses；
40 civil grille layers；
50 metallings；
60 asphalt concrete pavement layers；
The stake of 70 sides, 701 pile bodies, 702 first convex ribs, 703 second convex ribs.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
A kind of soft soil roadbed (i.e. original place base) ruggedized construction as depicted in figs. 1 and 2, including：
Pile layer 20, is made of the more piles squeezed into soft soil roadbed 10 201, and in the present embodiment, these piles can be with
Arranged by arrangement mode (such as in grid-like arrangement mode) predetermined in the prior art, each pile can be that whole whole is buried
Enter it is soft soil roadbed in or local embedment it is soft soil roadbed in, and it is local stretch out on soft soil roadbed, but each pile stretches out
It is no more than bed course in soft soil roadbed part, so can not only reduces each pile and squeeze into soft soil roadbed part and be squeezed into reducing
The difficulty of pile, can also play the role of bed course certain firm Anti-lost；
Bed course 30, is layed on soft soil roadbed 10, in fact, the bed course 30 also in pile layer 20 on；
Civil grille layer 40, is layed on bed course 30；
Metalling 50, is layed on civil grille layer 40；
Asphalt concrete pavement layer 60, is layed on metalling 50；
Two rows of piling walls, are respectively arranged on the both sides of asphalt concrete pavement layer 60, and more are included per campshed wall along predetermined side
To spaced side stake 70, every side stake 70 is squeezed into soft soil roadbed 10 including lower end and upper end extends to asphaltic concrete road
The pile body 701 of surface layer and one end are connected with pile body 701 and the other end stretches into the first convex ribs in asphalt concrete pavement layer 60
702。
Predetermined direction described in the present embodiment refers to the length direction of the roadbed (i.e. highway subgrade) of all buildings, example
Such as, as shown in Figure 1, the predetermined direction described in the present embodiment can be perpendicular to the direction of drawing plane.
The present embodiment in the construction process, after can first construct pile layer, bed course and civil grille layer, two rows of piling walls of constructing,
Hereafter construct again metalling and asphalt concrete pavement layer.
Every side stake 70 further includes that one end is connected with pile body 701 and the other end stretches into the second convex ribs 703 in metalling 50.
The technical solution can not only utilize metalling to make the stake of each side further by setting the second convex ribs stretched into metalling
Fixation is to reduce the risk that each side stake is lost, while the second convex ribs of each side stake can play metalling certain consolidate
Anti-lost acts on.
At a spacing, and the first convex ribs 702 are located at for the first convex ribs 702 and the second convex ribs 703 in every side stake 70
The top of second convex ribs 703, i.e., the first convex ribs 702 are close to the upper end of pile body 701, and the second convex ribs 703 are under pile body 701
End.
The bed course 30 is sand bedding course, and the present embodiment is by setting metalling and sand bedding course to have hydrophobic effect.
The civil grille layer 40 moulds civil grille layer for steel.
Each pile 201 is mini pile, which can be easy to the construction of pile.
Pile and side stake described in the present embodiment can be concrete-pile or timber.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
