1. Nkà na ụzụ ndabere
Ugbu a, a na-eji sistemụ WIM dabere na piezoelectric quartz na-atụ ihe mmetụta n'ọtụtụ ebe n'ọrụ dị ka nlekota oke ibu maka àkwà mmiri na ọwa mmiri, mmanye na-ebufe ibu na saịtị maka ụgbọ ala ibu okporo ụzọ, na njikwa oke ibu nke teknụzụ. Agbanyeghị, iji hụ na izi ezi na ndụ ọrụ, ọrụ ndị dị otú ahụ chọrọ nrụzi pavement simenti maka mpaghara ntinye ihe mmetụta piezoelectric quartz nwere ọkwa teknụzụ dị ugbu a.

Ihe kpatara enweghị ike itinye piezoelectric quartz na-atụ ihe mmetụta ozugbo na pavement na-agbanwe agbanwe bụ: Dị ka egosiri na eserese 1, mgbe wheel (karịsịa n'okpuru ibu dị arọ) na-aga na pavement na-agbanwe agbanwe, elu okporo ụzọ ga-enwe nnukwu ego. Agbanyeghị, mgbe ị na-erute mpaghara ihe mmetụta piezoelectric quartz siri ike, njirimara subsidence nke ihe mmetụta na mpaghara pavement interface dị iche. Ọzọkwa, ihe mmetụta na-atụ ihe siri ike enweghị njikọ kwụ ọtọ, na-eme ka ihe mmetụta na-atụ atụ agbaji ngwa ngwa wee kewapụ na pavement.

N'ihi njirimara subsidence dị iche iche yana ọnụọgụ esemokwu pavement dị iche iche, ụgbọ ala na-agafe piezoelectric quartz na-atụ ihe mmetụta na-enwe mmetụta siri ike, na-emetụta oke nha nha nha. Mgbe mkpakọ ụgbọ ala na-adịte aka, saịtị ahụ na-enwe ike imebi na mgbawa, na-eduga ná mmebi ihe mmetụta.
2. Ngwọta dị ugbu a n'ubi a: Nrụzigharị Pavement Cement Concrete
N'ihi nsogbu nke piezoelectric quartz na-atụ ihe sensọ enweghị ike itinye ya ozugbo na pavement asphalt, ihe a na-enweta na ụlọ ọrụ ahụ bụ nrụzi paịlị simenti maka mpaghara ntinye ihe mmetụta piezoelectric quartz. Ogologo nwughari n'ozuzu bụ 6-24 mita, na obosara ya na obosara okporo ụzọ.
Ọ bụ ezie na nrụgharị pavement ciment na-ezute ike achọrọ maka ịwụnye piezoelectric quartz na-atụ ihe mmetụta ma hụ na ndụ ọrụ, ọtụtụ okwu na-egbochi nkwalite ya zuru ebe niile, kpọmkwem:
1) Mwugharị simenti siri ike nwughari nke pavement mbụ chọrọ nnukwu ọnụ ahịa ihe owuwu.
2) Nrụgharị nke ciment na-achọ ogologo oge ihe owuwu. Oge ọgwụgwọ maka pavement ciment naanị chọrọ ụbọchị 28 (ụkpụrụ a chọrọ), enweghị mgbagha na-ebute mmetụta dị ukwuu na nhazi okporo ụzọ. Karịsịa n'ọnọdụ ụfọdụ ebe sistemụ WIM dị mkpa mana okporo ụzọ na saịtị dị oke oke, ịrụ ọrụ na-esikarị ike.
3) Mbibi nke usoro ụzọ mbụ, na-emetụta ọdịdị.
4) Mgbanwe mberede na ọnụọgụ esemokwu nwere ike ibute ihe egwu egwu egwu, ọkachasị n'ọnọdụ mmiri ozuzo, nke nwere ike ibute ihe mberede ngwa ngwa.
5) Mgbanwe na nhazi okporo ụzọ na-ebute ịma jijiji ụgbọ ala, nke na-emetụta nha nha nha ruo n'ókè ụfọdụ.
6) Enweghị ike ịrụgharị ciment kọnkịrị n'ụzọ ụfọdụ akọwapụtara, dịka àkwà mmiri dị elu.
7) Ugbu a, n'akụkụ okporo ụzọ okporo ụzọ, ihe na-emekarị si na-acha ọcha na-acha oji (ịgbanwe pavement ciment na pavement asphalt). Ihe ngwọta dị ugbu a sitere na oji ruo na-acha ọcha, nke na-ekwekọghị na ihe ndị dị mkpa, na ihe owuwu ụlọ na-eguzogidekarị.
3. Ọdịnaya nhazi nhazi emelitere
Ebumnuche nke atụmatụ a bụ iji dozie ụkọ piezoelectric quartz na-atụ ihe sensọ na-enweghị ike itinye ya ozugbo na pavement asphalt.
Atụmatụ a na-etinye kpọmkwem piezoelectric quartz na-atụ ihe mmetụta na oyi akwa siri ike, na-ezere okwu adịghị ekwekọ na-adịte aka site na ntinye kpọmkwem nke usoro ihe mmetụta siri ike n'ime pavement na-agbanwe agbanwe. Nke a na-agbatị ndụ ọrụ nke ukwuu ma hụ na ọ naghị emetụta nha nha.
Ọzọkwa, ọ dịghị mkpa ịrụgharị pavement simenti na pavement mbụ nke asphalt, na-azọpụta nnukwu ego a na-akwụ maka ihe owuwu ma na-ebelata oge ihe owuwu ahụ nke ukwuu, na-enye ohere maka nkwalite dị ukwuu.
Onyonyo 2 bụ schematic eserese nke ihe owuwu nwere piezoelectric quartz na-atụ ihe mmetụta etinyere n'elu ala dị nro.
(1-ụkwụ, ihe mmetụta 2-atụ, oyi akwa 3 dị nro, oyi akwa isi 4 siri ike, pavement 5 na-agbanwe agbanwe, mpaghara nri 6, mpe mpe akwa 7)
4. Isi Teknụzụ:
1) Ngwuputa ihe mgbochi nke ihe owuwu ntọala iji mepụta oghere nrụgharị, na oghere oghere nke 24-58 cm.
2) Ịkwalite ala nke oghere na ịwụsa ihe ndị na-ejuputa. A na-awụsa ntụ ọka quartz ájá + igwe anaghị agba nchara n'ime ala nke oghere ahụ, juputara nke ọma, yana omimi omimi nke 2-6 cm wee gbado ya.
3) Ịwụsa oyi akwa isi ike ma tinye ihe mmetụta na-atụ. Wunye oyi akwa siri ike ma tinye ihe mmetụta na-atụ n'ime ya, na-eji mpempe ụfụfụ (0.8-1.2 mm) kewapụ akụkụ nke ihe mmetụta na-atụ na oyi akwa siri ike. Mgbe oyi akwa ahụ siri ike gbasie ike, jiri igwe ihe na-egweri ihe mmetụta na-atụ ihe na oyi akwa isi ike n'otu ụgbọ elu ahụ. Okpokoro ntọala siri ike nwere ike ịbụ akwa akwa siri ike, ọkara siri ike, ma ọ bụ ihe mejupụtara.
4) Nkedo nke elu oyi akwa. Jiri ihe na-adaba na oyi akwa na-agbanwe agbanwe ka ị wụsa ma jupụta ebe dị elu nke oghere ahụ. N'oge a na-agbapụta mmiri, jiri obere igwe na-agbakọta ọnụ iji jiri nwayọọ nwayọọ na-agbakọta, na-eme ka ọkwa zuru ezu nke elu ahụ wughachi ya na ụzọ ndị ọzọ. Okpokoro ntọala na-agbanwe agbanwe bụ oyi akwa asphalt granular dị oke mma.
5) The ọkpụrụkpụ ruru nke isiike isi oyi akwa na-agbanwe isi oyi akwa bụ 20-40: 4-18.
