Cov yam ntxwv ntawm cov khoom cua dag
Nrog rau kev txhim kho ntawm lub sijhawm, kev sib raug zoo ntawm kev sib tw, kev siv cov casses dag tau siv ntau dua, qhov chaw ua si qeeb hloov qhov tseeb nyom siv nyob rau ntau lub teb, ces nws siv rau qhov chaw thiab nws yog yam dab tsi, hauv qab no yog yooj yim Qhia rau txhua tus.
Chaw ua si quab nyom siv tau rau hauv qhov chaw taug kev, kev ncaws pob, cov chaw ntaus pob, chaw ua si, chaw ua si, chaw ua si, rooj sib tw, kev sib tw ntaus pob, Kuj yuav siv tau rau hauv lub voj voog, qhov chaw thiab cov tsev kawm ntawv theem nrab thiab theem nrab, qib kindergarten thiab chaw ua si. Raws li zoo li kev greening ntawm txoj kev, railways thiab cov zej zog, kev kho kom zoo nkauj ntawm lub ru tsev thiab cov courtyards. 40-60 millimeters cov nyom siv hauv tsev kawm ntawv thiab qhov chaw ua si. 25-35 hli nyom siv hauv tsev kawm ntawv thiab cov khoom ua si 20 hli Nyom cov nram qab no siv hauv cov tsev hais plaub hauv chaw ua si, hockey tsev hais plaub, volleyball courts, runways thiab lwm txoj kev pavement. Yog li ntau qhov chaw siv cov khoom siv dag cua dub, khoom cua ua rau lub qhov kawg ntawm cov yam ntxwv zoo li cas?
Cov nta ntawm cov khoom cua dag:
Ua ntej, daim ntawv thov los ntawm tej yam kev mob ntawm cov nag, daus thiab lwm yam kev txwv, yog kev ua si ntawm "all-weather".
Thib ob, qhov ntau ntawm cov qauv kev tshawb fawb thiab kev siv technology tshiab, lub zog tensile zog, ceev ceev, yooj, txav lub zog, kev laus ua hauj, xim ncav kom txog qib siab.
Qhov peb, kev nyab xeeb yog qhov zoo. Kev siv cov cuab yeej kho mob thiab kev ua kis las thiab lwm cov cai, yog li ntawd ncaws pob ua si ntawm cov nyom, ligaments, cov leeg, pob qij txha, sib txuas, thiab kev tiv thaiv los ntawm kev poob qis thiab kev sib tsoo txo qis.
Qeb plaub, siv txoj cai ntawm kev qog ntawm ecology. Yog li ntawd tus neeg ncaws pob lub siab ntawm cov nyom, lub pob lub pob txha caj npab ceev thiab thiaj li nyob ze ze ntawm cov nyom nyob rau hauv lub natural, thiab muaj permeability.
Thib tsib, txoj haujlwm tu txhua hnub yog qhov yooj yim thiab luv nqi.
Rau, qhov nruab nrab kev pab cuam lub neej ntawm ntau tshaj 10 xyoo. Khoom phom cuav dag nyob teb chaws Europe nees nkaum xyoo dhau los no tseem siv tau. Lub chav kawm ntawm ntau yam ntawm hla hauv qhuav ntawm cov nyom dawb nrog lub sij hawm molding. Nws yog qhov khoom tiv thaiv ib puag ncig, nws tsis muaj cov khoom tsim kev puas tsuaj, thiab muaj lub suab nrov nqus.
