Description

The construction method of road base course on a kind of basement roof

Technical field

The present invention relates to technical field of buildings, and in particular to the construction method of road base course on a kind of basement roof.

Background technology

Nearly recent decades, in order to which right combination utilizes limited land resource, in civilian and public building planning and designing, Basement is more and more widely used, and the basement useful space is taken full advantage of.Outdoor ground surface is then integrated into utilization, and just It often realizes original function, buries various energy medium comprehensive pipelines, lay road, landscape, greenbelt etc..But in cell road In construction, many technology barriers have been encountered.It is relatively thin because banketing on basement roof, generally between the ㎜ of 700 ㎜ -1200.Top plate Flexible waterproof roll layer is done in structure, then adds fish tail and waterproof layer and filter layer.General basement top plate area is all larger, filtering Layer drainage grade is minimum, when a few days heavy rain is come when attacking, backfill is already impregnated with by rainwater, and keeps a large amount of rainwater on top plate, It can not drain into other than basement roof immediately.

And specific Road base way is designed, still routinely way：General underlayment is the ㎜ of 250 ㎜~300 thick 37 lime earth mix uniform compaction, cement bonded sand stone step matches steady layer of water after base is 300 ㎜, and face layer is+40 ㎜ bitumen layers of 80 ㎜.By It finishes up in building, various energy medium comprehensive pipelines are in full swing, and can not have underlayment to concentrate execution conditions；Therefore, only one The a bit of mix 37 lime earth compacting of segment, applies because amount is small and can not contact steady layer of water professional contingent, often only equal complete After portion's underlayment is finished, contact steady layer of water professional contingent applies.And before steady layer of water professional contingent constructs, carry out underlayment Rainwater impregnates for several times, and personnel's walking, vehicle roll, and early have become mud, until fine day arrival, is exposed to the sun through 2~3 days, Wind blows ash and rises, dusty, when road roller rolls for the second time, is gushed on muddy water, mud turns over, and becomes mud spring layer, can only Excavate and reform, brings difficulty to Road base layer construction, the duration is caused to lag.A kind of completely new meet reality so only inventing The construction technical method of border situation, to ensure the construction quality and constructing aims of cell road foundation underlayment.

Invention content

The present invention provides a kind of construction method of road base course on basement roof, it is therefore intended that solves above-mentioned background skill The general basement top plate area proposed in art is all larger, the minimum problem of filter layer drainage grade.

To achieve the above object, the present invention provides a kind of construction method of road base course on basement roof, includes Construction content and step below：

Step 1 is planned center line on the fish tail and waterproof layer or trap drainage layer of basement roof, and is put along center line Outlet based underlayment side slope line, in over-the-counter mix dirt.

Dirt thickness control elevation line is determined in step 2, testing, is layered the dirt that paves.Stop compacting surplus.Road roller rolls It is closely knit.Various base tube lines of passing by one's way are buried in time.

Step 3, after dirt Density Detection qualification, the single layer reinforced mesh of timely assembling reinforcement concrete base layer.

Step 4, after steel corrosion quantity qualification, timely pouring reinforcement concrete base.

Step 5 cleans up after armored concrete base has all constructed, and cement bonded sand stone step matches steady layer of water.

Step 6, laying road curb, the road edge stone include curb kerbstone and the flat stone of curb.

Step 7, curb be laid with after, after qualification of inspecting for acceptance, clean up armored concrete base, dry or After wind is dry, pave asphalt base course and asphalt surface course.

Preferably, the dirt is 37 lime earth.

Preferably, the armored concrete base includes C35 concrete, and the thickness of the armored concrete base is 150 ㎜。

Preferably, reinforcing bar used in single layer reinforced mesh is 8 reinforcing bars of φ, the single layer reinforced mesh in the step 3 For the grid of 200 ㎜ of two-way spacing.

Preferably, paving thickness of the cement bonded sand stone step with steady layer of water is 150 ㎜ in the step 5.

Preferably, curb kerbstone and the flat stone absolute altitude error of curb are controlled in the step 6, ensure asphalt thickness

Specific implementation mode

In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to Limit the present invention.

Below in conjunction with the accompanying drawings and specific embodiment is further described the application principle of the present invention.

Embodiment one

The construction method of road base course on a kind of basement roof as depicted in figs. 1 and 2, includes in following construction Appearance and step：

Step 1 plans center line 2 on the fish tail and waterproof layer 4 or trap drainage layer 5 of basement roof 3, and along center Line 2 releases roadbed underlayment side slope line 1, in over-the-counter mix dirt 6.

6 thickness control elevation line of dirt is determined in step 2, testing, is layered the dirt 6 that paves.Stop compacting surplus.Road roller is ground Densification is real.Various base tube lines of passing by one's way are buried in time.

Step 3, after 6 Density Detection qualification of dirt, the single layer reinforced mesh of timely assembling reinforcement concrete base layer 7.

Step 4, after steel corrosion quantity qualification, timely pouring reinforcement concrete base 7.

Step 5 cleans up after armored concrete base 7 has all constructed, and cement bonded sand stone step matches steady layer of water 8.
