1. Lub raj xa dej yuav tsum tau muab tso rau ntawm lub hauv paus hauv av uas tsis muaj kev cuam tshuam los yog lub hauv paus ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom tom qab slotting. Thaum lub raj xa dej nyob hauv qab txoj kev, cov av npog saum cov yeeb nkab yuav tsum tsis pub tsawg dua 0.7m.

2. Thaum lub sij hawm tsim kho, qhov rigidity ntawm lub nplhaib yeeb nkab yuav tsum tau rov qab xyuas dua - raws li qhov siab tshaj plaws npog av nyob rau sab saum toj ntawm cov yeeb nkab. Yog tias qhov rigidity ntawm lub nplhaib yeeb nkab tsis ua tau raws li cov qauv tsim, kev siv yuav tsum tau nres tam sim ntawd; cov av tsis muaj kev cuam tshuam ntawm qhov zawj thiab nws sab yuav tsum tau kuaj xyuas, thaum pom tias tsis sib haum nrog cov qauv tsim, cov qauv tsim yuav tsum raug hloov lossis ib qho kev lav zoo ntawm cov kav dej muaj peev xwm yuav tsum tau txais yuav.

Cov kev ntsuas muaj zog.

3. Thaum cov kav dej ntws hla txoj kev tsheb ciav hlau thiab txoj kev loj, kev ntsuas xws li casing yuav tsum tau teeb tsa, thiab tsim cov casing yuav tsum tau ua raws li cov kev cai ntawm txoj kev tsheb ciav hlau thiab txoj kev loj.

4. Thaum cov dej hauv av siab tshaj qhov hauv qab ntawm qhov khawb av, cov dej hauv av yuav tsum poob mus rau hauv qab 0.5m nyob rau hauv qab ntawm lub trench. Thaum lub sij hawm tag nrho cov txheej txheem ntawm kev tso thiab backfilling ntawm lub raj xa dej, hauv qab ntawm lub trough yuav tsum tsis txhob ntim dej los yog khov, thiab kev txo cov dej hauv av yuav tsum tsis txhob tso tseg kom txog thaum lub phiaj xwm tsis cuam tshuam los ntawm cov dej hauv av thiab cov kav dej raws li kev tiv thaiv {{ 3}}floating Requirements.

5. Thaum cov twj tso kua mis yog siv los ua ib qho inverted siphon hla nrog lwm cov kav dej, nws cov kev ua haujlwm siab yuav tsum tsawg dua 0.05Mpa ntxiv rau kom ua tau raws li cov khoom lag luam ntawm cov yeeb nkab.

6. Lub raj xa dej yuav tsum tau muab tso rau hauv txoj kab ncaj nraim. Thaum nws yog ib qho tsim nyog siv lub ces kaum ntawm qhov hloov pauv hloov pauv lossis siv qhov hloov pauv ntawm cov yeeb nkab rau folded lossis arc tso rau hauv qhov xwm txheej tshwj xeeb, lub kaum sab xis deflection thiab dabtsi yog khoov arc yuav tsum nyob rau hauv qhov kev teeb tsa thiab siv.

7. The technical requirements of pipeline construction such as measurement, precipitation, grooving, groove support and pipeline crossing treatment, pipeline construction in the same groove, etc., should be in accordance with the current national standard "Water Supply and Drainage Pipeline Construction and Acceptance Specifications" GB50268 and the technical regulations for drainage pipelines in the region. Implementation of relevant regulations.
