Description
Technical field
The present invention relates to a kind of soft soil roadbed technical field of construction of municipal administration, more particularly to a kind of municipal administration is soft soil roadbed to be applied
Work method.
Background technology
The complicated component of weak soil, contain the Chemical Genesis such as substantial amounts of carbonate and evaporite material and humic soil chip etc.
Biogenesis material, soft scholar are usually to deposit to form in flowing water environment, with silt particle and obvious stratification are presented, area
Otherness is larger, soft soil roadbed mainly to have following several respects feature：It is soft soil roadbed that there is the spy that water content is higher, hole is bigger
Point；Weak soil has obvious structural；With obvious rheological characteristic；Compressibility is high, bad hydraulic permeability；Shear strength is very low.
Road is built in soft clay area, the problems such as road settlement deforms often occurs, the use of road is had a strong impact on, and
And huge economic loss is therefore caused, or even irreparable consequence is caused, in recent years, with expanding economy, city rule
Mould constantly expands, and the urban road that China is completed and built at present, the roadbed in many regions is soft soil roadbed, Soft Soil Layer
Thicker, distributed more widely, soft soil roadbed processing work turns into the emphasis of road construction research, generally, soft soil roadbed to city road
The adverse effect on road is mainly due to soft soil roadbed shearing strength deficiency, it is difficult to the load action of road surface transmission is born, in lotus
It is soft soil roadbed under load effect to produce locally or globally failure by shear, so as to produce road surface embankment landslide, unstability, cause road
The destruction of structure sheaf, therefore, it is necessary to solve the above problems to invent a kind of soft soil roadbed construction method of municipal administration.
The content of the invention
It is an object of the invention to provide a kind of soft soil roadbed construction method of municipal administration, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the present invention provides following technical scheme：A kind of soft soil roadbed construction method of municipal administration, including

Muscle, the load bearing support muscle runs through concrete strengthening layer, bed course and hard stratum, and extends in Soft Soil Layer, the bed course both sides
Top is provided with breast boards, and the breast boards side is provided with limiting plate, and described limiting plate one end is extended in Soft Soil Layer；
The construction method installation following steps are carried out：
Step 1：Grooving flattens：Grooving is carried out with digging machine on Soft Soil Layer, and after grooving terminates, enters walking along the street with road roller
The flat processing of face pressure；
Step 2：The processing of pre-buried and bed course：It is pre-buried some with vertical strengthening ribs in hard stratum after pressing, and vertically add
Strengthening tendons bottom extends in Soft Soil Layer and fixed, and then tentatively pours into concrete to pan soil layer surface；
Step 3：Breast boards and reinforcement arrangement：It is artificial to carry out breast boards arrangement and add when mat surface concrete layer solidifies
Strengthening tendons is arranged；
Step 4：Back-up coat is set：After reinforcement and breast boards arrange, a certain amount of concrete stirring is poured into bed course
Liquid；
Step 5：Manually smooth out with the fingers gentle protection：After concrete stirring liquid injection terminates, manually progress surface is smoothed out with the fingers flat, after smoothing out with the fingers flat,
In concrete stirring liquid surface laying diaphragm.
Preferably, grooving depth is arranged between 20cm-30cm in step 1.
Preferably, cushion thickness is arranged between 5cm-8cm in step 2, and vertical strengthening ribs top is pre- apart from bed course top
Staying height, concrete uses C15 standard concretes between 7cm-10cm, and according to its component and the mass fraction of each component
For cement：Stone：Gravel：Water：Coagulator=1:4:2:0.6:0.02 match ratio.
Preferably, the breast boards in step 3 is the smooth wooden boards in surface, the earth-retaining plate thickness be 2cm-4cm it
Between, the breast boards is highly between 40cm-50cm.
Preferably, the concrete stirring liquid employed in step 4 is arranged to C25 standard concretes, and according to its component
And the mass fraction of each component is cement：Stone：Gravel：Water：Coagulator=1:1.7:1:0.4：0.01 match ratio.
Preferably, antifreeze is also contained in the C25 standard concretes, and its component accounts for the match ratio of mixed liquor and is
0.008。
Preferably, also contain later maintenance in step 5, when concrete tentatively solidifies, raise diaphragm every three days,
And sprinkled water toward concrete surface, after this process is until carry out 3-4 times, remove diaphragm.
The technique effect and advantage of the present invention：The present invention is carried by carrying out distributed back-up coat setting to soft soil roadbed
The high bearing capacity of roadbed, and roadbed is not easy and is caved in, the service life of roadbed is improved, and in injection concrete
When, each back-up coat selects the concrete and addition coagulator of varying strength, so as to effectively raise the quality of roadbed, and
This construction method is simple, easily implements.
