Description

For reinforcing the fiberglass pipe sheet devices of existing operation tactics

Technical field

The utility model belongs to existing operated subway reinforcement technique field, and existing operated subway is reinforced more particularly, to one kind Tunnel glass fibre section of jurisdiction, that is, it is used for the fiberglass pipe sheet devices for reinforcing existing operation tactics.

Background technology

In recent years, as the development of China's urbanization, construction of subway engineering are carried out in high gear in each big city.Mesh Before, the existing 19 city underground engineerings in China are being built, and about 13 city underground engineerings are planned.However, due to structure master There is the reasons such as space, differential settlement in stress and secondary stress, deformation, lining cutting back and the soil body, significant proportion was both The problem of excessive is deformed with the presence of operation shield tunnel liner.Way station-Huai-Hai area of way station is revived with Shanghai Rail Transit Line No.8 line Between tunneling shield driving to the influence of established tunnel exemplified by, because two tunnels are closely constructed, shield driving makes built tunnel Road deforms, and established tunnel section interface also generates different degrees of deformation.Established tunnel in shield driving coverage Different degrees of opening substantially occurred for flexible interface, and open width maximum reaches 3mm.Built tunnel in the range of shield driving Road rigid interface totally 190, wherein 16 there occurs local opening, at tunnel both ends close to active well position and maximum vertical Respectively there is the tube coupling concrete fragmentation near one of rigid interface damaged at deformation.

Because the lining cutting conference that deformed destroys the attractive in appearance of structure, cause to bind block and adjacent block disengages, joint opens Measure the disease of a variety of durability deficiencies such as excessive, circumferential weld faulting of slab ends, duct piece connector damage, lining cutting steel bar corrosion and structural concrete corrosion Evil occurs, and then destroys the integrality of structure and reduce their durability, so as to which the situation of percolating water in tunnel increases, influences The safety and service life of shield tunnel.If handled not in time lining damages, destruction can be further increased, even Tunnel cave, life threatening and property safety can be caused.

Therefore, in order to control the development that subway tunnel deforms, reinforced mostly using steel pipe sheet at present in engineering, grouting and reinforcing The method being combined is reinforced with aramid fabric.But steel pipe sheet reinforces transport and construction expends a large amount of human resources, long construction period, adds Gu cost is high, it has not been convenient to construct, this body structure of tunnel and shape are had a great influence, and steel pipe sheet anti-corrosive properties are poor, it is fragile.And Due to the characteristics of adding soil layer low-intensity, high-compressibility, high sensitivity and rheological characteristic in soft clay area, grouting and reinforcing construction is not easily-controllable , usually there is running pulp, spillage and situation about starching partially in system, and additional harmful effect is caused to tunnel structure, exacerbates lining cutting disease on the contrary Harmful generation.In order to control the development of tunnel deformation, aramid fabric has been introduced into tunnel reinforcement engineering field, good so as to serve Limitation tunnel deformation development, the maintenance tunnel water proofing impact of performance.

Now, appearing on the market with various good fiber quality materials, glass fiber material is as a kind of the inorganic non-of excellent performance Metal material, gradually praised highly in concrete strengthening engineering.Glass fiber material is a kind of excellent performance without metal material Material, species is various, and advantage is good insulating, heat resistance is strong, corrosion resistance is strong, high mechanical strength, sound absorption properties good, and it is with glass Ball or discarded glass are raw material through high temperature melting, wire drawing, doff, and the technique such as weave cotton cloth is made, per bundle fiber precursor all by Hundreds of even thousand monofilament compositions, there is extensive development prospect.
