Detailed description of the invention
Below in conjunction with
accompanying drawingand embodiment, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
See
fig. 1extremely
fig. 5the described not subjected to pressure formula reinforcing pipes structure being applicable to road surface, include road surface built-in groove 1, for the ease of follow-up location of pipeline, reduce the secondary excavation to original road bed as far as possible, in road surface built-in groove 1, be provided with basal layer 2, its unusual part is: be provided with in basal layer 2 both sides and symmetrical block assembly 3.The benefit done like this is, can effectively bear the lateral stress that may exist, and ensures that the follow-up pipeline installed of laying is not subject to transverse shear stress.Meanwhile, in order to meet the protection of effective seal, preventing Groundwater infiltration from corroding, being connected with cover plate 4 blocking assembly 3 top.
Meanwhile, consider and can effectively cut off for the infiltration that road crust is downward, cover plate 4 is provided with partition component 5.Thus, allow block assembly 3, cover plate 4 forms airtight guard space each other.Further, in guard space, packed layer 6 is distributed with.Like this, not only meet the completely isolated of pipeline and external environment, packed layer 6 can also be allowed to absorb stress from outside all directions, can not impact pipeline itself.
Certainly, in order to protect more comprehensively the pipeline of subsequent installation, while strengthening its firmness, be isolated with external environment condition further, also need also to be provided with pipe strengthening assembly 7 on basal layer 2.
In conjunction with the present invention one preferably embodiment, the assembly 3 that blocks of the present invention includes bottom substrate layer, and this bottom substrate layer is provided with side direction reinforcement walls.Consider the facility of actual construction, bottom substrate layer, side direction reinforcement walls are brick wall structure.In order to avoid there is unnecessary depression in road surface built-in groove 1, strengthen the contact surface with road surface built-in groove 1, the width of bottom substrate layer is greater than the width of side direction reinforcement walls.
Come from the longitudinal stress that road surface applies downwards can be dissipated in time and dredge to ensure to allow, the two ends on basal layer 2 top are distributed with lead-in chamfered 8, make pipe strengthening assembly 7 be positioned at the intersection of lead-in chamfered 8.Like this, though by packed layer 6 pass over a part not by the extraneous stress dissipated, can be applied to as far as possible on pipe strengthening assembly 7 by lead-in chamfered 8 yet.
Further, preferably guide to have, the angle that lead-in chamfered 8 and horizontal plane are arranged is 15 degree to 60 degree.Find by after repeatedly contrast experiment, preferably effect can be played according to the angles of 45 degree.Moreover the packed layer 6 of employing is sandstone, gravel mixing packed layer 6, has preferably density and simultaneously, also have suitable mobility, effective cushioning effect can be played.For the construction environment of some special region, cement injection back-up coat also can be adopted to form packed layer 6, and be distributed with rubble filler in cement injection back-up coat.Like this, the support without mobility can be realized, effectively improve overall firmness.
Further, in order to carry out effective auxiliary protection to the follow-up pipeline worn, pipe strengthening assembly 7 of the present invention includes support passage 9, and this support passage 9 periphery is enclosed with encapsulating layer 10.Like this, even if there is extraneous Stress transmit to come, also can realizes secondary by encapsulating layer 10 and dissipate.Meanwhile, rely on the existence of encapsulating layer 10, even if suffer suddenly excessive extraneous stress, cause reinforcing bar catch net 11 to occur unexpected cracked, also can ensure can not cause secondary injury to support passage 9.Consider the location to encapsulating layer 10, prevent from occurring getting loose in construction period, be distributed with reinforcing bar catch net 11 in encapsulating layer 10 periphery.Further, be wrapped with scrim cloth 12 at reinforcing bar catch net 11, this scrim cloth 12 is outer is also provided with overcoat 13.Thereby, it is possible to effectively prevent harmful environmental material, the such as invasion of seepage in underground, corrosive deposit.
Meanwhile, consider the ability to bear promoting support passage 9 pairs of longitudinal stresses, be vertically installed with auxiliary support bar 14 within it, these auxiliary support bar about 14 two ends contact with support passage 9 inwall.Further, in order to be unlikely to occur that encapsulating layer 10 is excessive during use, the reinforcing bar catch net 11 of employing includes housing, is distributed with groined type grid in this housing.Can the protection of suitable dough deformation in order to have one, avoid occurring cracked, the overcoat 13 that the present invention adopts is crushed crude pearlite, resin glue mixed layer.For the needs of some special laying environment, can also be form overcoat 13 by quartz sand and mixed with resin.Find by after repeatedly contrast experiment, adopt 5 centimetres of encapsulating layers 10 to 10 cm thick intervals can play preferably protection effect, and not easy to crack.And scrim cloth 12 adopts the stacking parcel of one deck to five layer cloth can play various different insulating effect, meets the construction demand of different geographical.
Again further, in order to allow the ponding that infiltrates from road surface or underground water is unlikely to be delivered to rapidly cover plate 4, prevent from further infiltrating to be deposited on packed layer 6 causing two subintrusion, the partition component 5 that the present invention adopts includes pervious layer 15.Meanwhile, this pervious layer 15 upper surface is equipped with geotechnological layer of cloth 16, is equipped with basic unit 17 at geotechnological layer of cloth 16 upper surface.
And, when the geotechnological layer of cloth 16 of appearance, basic unit 17 all cannot keep out the situation of water immersion, in order to discharge in time, avoid saving bit by bit on cover plate 4, and be dispersed in the whole soil layer of follow-up landfill as far as possible, specifically, pervious layer 15 is hollow out porous disc, this hollow out porous disc includes plate body 18, and plate body 18 is distributed with some permeable holes 19, and permeable hole 19 equidistantly distributes each other.Meanwhile, consider the supporting capacity promoting hollow out porous disc, cracking can not be occurred when suffering stress, also can be provided with honeycomb grid 20 in plate body 18.
In conjunction with actual construction layout, the present invention adopts pervious layer 15 thickness to be 6 centimetres to 8 centimetres.Corresponding with it, geotechnological layer of cloth 16 is individual layer or the stacking formation of double-deck geotextiles.Further, basic unit 17 thickness is 15 centimetres to 20 centimetres.
In order to better implement the present invention, now provide a kind of not subjected to pressure formula reinforcing pipes construction method being applicable to road surface, it comprises the following steps:
