Description
Technical field
The utility model belongs to Geotechnical Engineering stability of slope supporting field, and more particularly, to one kind is subject to using reducing retaining structure
The road structure that the off-loading supporter system of power builds.
Background technology
Traditional supporting file version is various, but all has Rock And Soil to fill after supporting file structural walls, and Rock And Soil is prose style free from parallelism material
Material, inevitably brings soil lateral pressure to a mark structure, when soil lateral pressure is sufficiently large, causes the broken of a mark structure
Bad, cause support system to lose efficacy.In municipal administration, road and bridge and underground engineering, this engineering project disaster happens occasionally, due to soil body deadweight
Greatly, cause retaining structure or lower overlying strata soil bearing capacity not enough, in order to solve Lack of support, need to improve a mark structure chi
Very little, or lower earthing ground is processed to improve its bearing capacity, thus extending construction period, also improving engineering and making
Valency.
Also have in prior art and retaining structure is improved to resist soil lateral pressure, such as Application No.
201510626834.8 a kind of combination retaining structure and its construction method, Application No. 201310734532.3 a kind of reinforcement
Soil structure and the compound retaining structure of friction pile combination, are all on the basis of not changing Rock And Soil filling material, to a gear knot
Structure improves, and increases fixing force to Rock And Soil for example with GSZ, or increases friction pile, anchor pole etc. and increase to filling
The keeping out of the soil lateral pressure of Rock And Soil, these methods can only be arranged as remedying of being taken on the basis of existing issue
Apply, and fundamentally do not solve the generation of soil lateral pressure.
In a kind of method of reduction soil pressure on retaining wall in expansive rock-soil area of Application No. 201110064448.6, adopt
Load ground in soil engineering bag and be then placed within to reduce soil pressure after retaining wall, the soil engineering bag in this method remains variable
The soft material of shape, soil engineering bag is individually individual as one, not only itself there is deformation and continues transmission soil pressure, and mutually
Between there is also relative deformation, in the course of time it is impossible to play reduce soil pressure effect.
Content of the invention
It is necessary to propose a kind of subtracting using reduction retaining structure stress that can fundamentally solve soil lateral pressure generation
The road structure that lotus supporter system builds.
A kind of using reduce retaining structure stress off-loading supporter system build road structure, including road surface, guardrail,
Base, supporting barricade, be located at the supporting barricade back side lightweight concrete filling body, the lower section of lightweight concrete filling body setting
C25 concrete basal layer and compacting layer, the low side of described supporting barricade is deeply tamped layer and is fixed on inside compacting layer, in supporting barricade
Front every the distance of 800mm, one layer of bar-mat reinforcement is set, described bar-mat reinforcement is longitudinally laid along road, described bar-mat reinforcement following
Deeply tamp layer and be fixed on inside compacting layer, embedded anchor bar in lightweight concrete filling body, with by bolt anchorage lightweight
Combination stability between concrete filling body and ground, described road surface and guardrail are laid on ground and lightweight concrete filling body
Top, to form the road structure with the off-loading supporter system reducing retaining structure stress, described lightweight concrete fills
Body includes the prefabricated block that multiple-layer horizontal is put, and each layer of prefabricated block includes some spaced independent prefabricated block, on
Between the independent prefabricated block of layer prefabricated block and the independent prefabricated block of lower floor's prefabricated block, fissure of displacement overlap joint arrangement, lightweight is mixed
Solidifying soil paste material is poured in the gap at interval between independent prefabricated block, so that independent prefabricated block is connected to become lightweight concrete
Filling body.
Preferably, between described anchor pole and horizontal plane it is in 15 ° of angles.
Preferably, it is used for the foundation pile of nonfloating rail in lightweight concrete filling body internal preset.
The utility model replaces the big Rock And Soil of unit weight to fill using lightweight concrete filling body, due to lightweight concrete
Deadweight is little, and forms an entirety after solidification, does not transmit lateral pressure, such retaining structure is not subject to this lightweight concrete building body
Lateral pressure, thus reducing the stress of a mark structure, also reduces down the stress covering ground Rock And Soil, before can exempting construction
Process to ground, so, shortens construction period, reduces engineering directly or indirectly cost, has obvious economical, social
And environmental benefit, comprehensive benefit projects, and is a kind of advanced to fill mode.Meanwhile, the lightweight coagulation adopting in the utility model
Native slurry fluidity is good, is adapted to pump on a large scale, and Mechanization Level is high, and labor strength is low, in addition, suitably can be real
Existing self-compaction, it is to avoid manually vibrate, there is provided efficiency of construction.
