Cov ntsiab lus qhia ntxaws ntxaws rau Basalt Fiber Nruam Txhim Kho Kev Txhim Kho Pavement

I. Preprocessing thiab Positioning ntawm Composite Reinforcement Rolls
1. Cia thiab Unpacking ntawm Reinforcement Rolls
- Specifications: Txhua yob ntawm basalt fiber ntau Composite reinforcement ntsuas 600 m nyob rau hauv ntev thiab hnyav 18 kg.
- Kev tuav: Khaws cov yob horizontally nyob rau hauv lub voj voog. Tshem tawm cov ntim khoom sab nrauv thiab ua tib zoo coj qhov kev txhawb nqa kawg mus rau txoj haujlwm tsim kom tsis txhob sib tw lossis khoov.

2. Kev soj ntsuam hauv paus
- Siv tag nrho cov chaw nres tsheb lossis cov khoom siv laser sib dhos kom meej meej rau qhov chaw ua haujlwm ntawm cov khoom siv sib xyaw ua ke thiab cov chaw sib koom ua ke raws li cov duab kos duab. Cov ntsiab lus tseem ceeb ntawm kev tswj hwm yuav tsum raug txheeb xyuas kom meej.

II. Installation thiab Binding ntawm Composite Reinforcement Mesh
1. Transverse Reinforcement Installation
- Txhim kho cov kev txhawb nqa transverse ntawm cov rooj zaum txhawb nqa, ua kom lub kaum sab xis 60 ° nrog kev txhawb nqa ntev. Ruaj ntseg khi qhov kawg kom tiv thaiv kev txav chaw.
- Kev tswj qhov siab: Lub composite reinforcement mesh yuav tsum yog 10 cm qis dua cov pavement vaj huam sib luag, nrog rau sab nrauv qhov cuab lub zog khaws cia ≥90 hli los ntawm cov npoo dawb.

2. Kev them nyiaj yug qauv Kev tsim kho 
- Fabricate U-shaped steel txhawb siv Φ25 mm ribbed Hlau Bars, spaced 25 cm longitudinally thiab 50 cm transversely, kom stabilize lub composite reinforcement mesh.
- Muab lub ntsiab load-bearing composite reinforcements nyob rau hauv cov cheeb tsam ntawm qhov siab tshaj plaws khoov kev nyuaj siab, nrog transverse reinforcements spaced 50 cm nyob rau hauv qab ntawm longitudinal tuav.

3. Cov txheej tiv thaiv thiab hnav-Resistant
- Cov Txheej Txheem Hauv Qab: Ib txheej 180 hli tuab tiv thaiv yog teem nruab nrab ntawm cov hlua txuas ntxiv thiab subbase los tiv thaiv kev yaig.
- Sab saum toj hnav-Resistant Txheej: Ib txheej 50 hli tuab hnav-tiv taus yog ntsia rau saum cov mesh txhawm rau txhim kho kev ua haujlwm ntev.

III. Longitudinal Reinforcement thiab Joint Construction Control
1. Longitudinal Reinforcement Spacing thiab Precision
- Ntev ntev qhov sib nrug yuav tsum yog ≤250 hli thiab tshaj 2.5 npaug ntawm lub ncov sib sau loj (piv txwv li, rau 10 hli aggregate ncov, qhov sib nrug ≥25 hli).
- Siv qhov chaw clamps los xyuas kom meej qhov kev teeb tsa, nrog kev sib txawv tswj hauv ± 5 hli.

2. Longitudinal Joint Tie Bars
- Φ25 hli ribbed steel tuav yog siv rau longitudinal sib koom khi tuav, densely teem nyob rau hauv cov cheeb tsam sib koom ua ke.
- Tag nrho-dav paving seem tuaj yeem tshem tawm cov pob qij txha ntev kom tshem tawm cov ntsiab lus tsis muaj zog.

IV. Prestressed Reinforcement thiab Txhawb Kev Txhim Kho
1. Prestressed Longitudinal Composite Reinforcement
- Siv Φ25 hli steel tuav raws li prestressed longitudinal reinforcements, nrog anchorage lengths nruj me ntsis tswj ntawm 3.0 m.
- Sib tshooj ntev li ntawm 60-100 cm, ruaj nrog epoxy resin tom qab khi los xyuas kom muaj kev sib txuas seamless.

2. Txhawb Prefabrication thiab Fixation
- Prefabricate steel txhawb nqa thiab ncej puab pob qij txha raws li tus qauv tsim. Laum qhov ** 10-15 cm los ntawm cov npoo dawb thiab cov pob qij txha ntev ** nyob rau hauv lub subbase, embed kev txhawb nqa, thiab weld thauj tog rau nkoj tuav.

V. Kev Tsim Kho Cov Qauv thiab Kev Tswj Xyuas Zoo
1. Kev Ua Raws Cai
- Ua raws li GB 50010-2010 (Code for Design of Cov Khoom Siv Ua Haujlwm) rau overlap binding, tiv thaiv txheej thickness, thiab lwm yam tsis.

2. Cov Cai Txais Tseem Ceeb
- Flatness sib txawv ntawm qhov kev txhawb nqa mesh: ≤3mm / m.
- Ua cov kev sim rub tawm ntawm thaj chaw epoxy resin-bonded, yuav tsum muaj lub zog ntawm ≥2.5 MPa.

VI. Tej teeb meem thiab kev daws teeb meem
- Qhov teeb meem 1: Mesh Misalignment
Kev daws: Txhim kho cov clamps ib ntus thiab tso cov ncej ntawm 5 m ib ntus.
- Qhov teeb meem 2: Tsis muaj zog Epoxy Bonding
Kev daws: Xyuas kom cov khoom sib txuas yog huv si thiab qhuav. Tswj curing kub ntawm 15-30 ° C thiab kho lub sij hawm ≥24 teev.
