Description

A kind of attachment device of pile slab structure floorings and roadbed
Technical field:
The present invention relates to highways to build new technical field, and in particular to a kind of company of pile slab structure floorings and roadbed Connection device.
Background technique:
With the development of Modern Traffic science and technology and information technology, work and the accelerating rhythm of life, people are to fast and easy The cry of trip is higher and higher.In recent years, China increases infrastructure construction speed, but as urbanization scale continues to increase, Increased population, corresponding volume of transport and car quantity rapid growth, urban traffic blocking and environmental protection problem are got over It more protrudes, mass rapid highway reconstruction and expansion is extremely urgent.
There are problems, such as expropriation of land difficulty, the amount of banketing are big for conventional reorganization and expansion method;Long construction period, social shadow It rings big;Environment is polluted, not environmentally etc..Common solution has: stake plate type retaining wall, halfway up the hill half-bridge, pile slab structure etc., but all The defects such as there are restricted applications, and cost is higher, and assembling degree is low.
Peg board formula roadbed is being saved the area, and construction period is shortened, and has huge advantage in terms of reducing construction infection, to week Surrounding environment influences small, prefabricated construction degree height, short construction period, good economy performance, with very big promotional value.Pile slab structure road Base is mainly made of part-structures such as reinforced concrete bridge deck plate, steel bar concrete pile, bent cap and inter-pile soils.For how to have Effect connects each component, is to be worth the problem of inquiring into especially by floorings and roadbed lateral connection.
Summary of the invention:
The invention reside in defect existing in the prior art is overcome, a kind of good integrity, the peg board knot of construction is simple are provided The attachment device of structure floorings and roadbed.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
A kind of attachment device of pile slab structure floorings and roadbed, it is characterised in that: including plain concrete cushion layer, cushion block, Beam slab, former roadbed, drainage network, the polyurethane cementation of fissures, cast-in-place piece, polyester fiber cloth and asphalt concrete pavement;The cushion block is set It sets in the upper outside position of plain concrete cushion layer, the beam slab is fixed at the upside of cushion block, and the former roadbed is set It sets and pours lap belt, the drainage network after being provided between plain concrete cushion layer inner side, the beam slab and former roadbed It is arranged on the lateral surface of former roadbed and is poured in lap belt after being located at, the outside of drainage network is arranged in the polyurethane cementation of fissures, Described cast-in-place piece is cast between cushion block, beam slab and the polyurethane cementation of fissures, and the polyester fiber cloth is arranged in beam slab, cast-in-place piece With the upside of former roadbed, the asphalt concrete pavement is laid on the upside of polyester fiber cloth.
The polyurethane cementation of fissures with a thickness of 1cm, the drainage network with a thickness of 2cm, cast-in-place piece of the width Degree is 95cm.
The width of the cushion block is 30cm.
Weeper drain, the interval between the weeper drain are laterally evenly arranged on the upside of the plain concrete cushion layer Distance is 3m.
Pervious concrete bed course is provided on the upside of the asphalt concrete pavement.
The asphalt concrete pavement is with a thickness of 1mm or more.
The pervious concrete bed course with a thickness of 20cm, the plain concrete cushion layer with a thickness of 10cm.
The present invention is handled disease old road roadbed, is such as tamped after existing roadbed is excavated to base surface With grouting etc., meet the requirements after-pouring blinding concrete.Blinding concrete is divided into two layers, and upper layer is the permeable coagulation of 20cm thickness C20 Soil padding, lower layer are the impermeable water subfill of 10cm thickness plain concrete, and emulsified asphalt waterproof layer is arranged between two layers of bed course.Mat surface One of weeper drain is arranged in every 3m.Lap belt is poured after 95cm wide is set between floorings and existing roadbed, is set on the outside of lap belt Set 30cm wide cushion block.The expansion joint 1cm is set between Bars In Poured Concrete Slab transverse direction and cement stabilized macadam, with the highly-elastic urethane cementation of fissures.High-elastic poly- ammonia 2cm thickness three-dimensional water discharge geonet is laid on the inside of the ester cementation of fissures.
The pervious concrete requires water penetration to be not less than 1mm/s, logical to form water draining between good lateral supercrust Road, emulsified asphalt waterproof layer film thickness are not less than 1mm.For treated disease old road roadbed, it is desirable that the comprehensive rebound mould in its top surface Amount is not less than 80MPa.The comprehensive modulus of resilience in roadbed top surface should be verified using drop hammer deflection meter, such as fallen short of the target and wanted It asks, then the embankment for coping with roadbed and deeper continues to handle, until can pour blinding concrete not after meeting the requirements It is able to increase blinding concrete thickness to replace roadbed to handle.
Advantageous effects of the invention: globality of the present invention is preferable, and construction is simple is saved the area, to surrounding enviroment Influence small, prefabricated construction degree height, short construction period, good economy performance, with very big promotional value.
