CON­TROL AU­TO­MA­TION GAIN­ING TRAC­TION IN SOIL COMPACTION

Mar­ket re­search firm Fact.mr presents in­sights from its study on soil compaction ma­chines, which re­veals that con­trol au­to­ma­tion of soil compaction ma­chines could re­sult in over 25% in­crease in op­er­a­tional per­for­mance and out­put

PMV Middle East - - COMPACTION -

Dy­namic compaction of soil us­ing qual­ity equip­ment has been deemed ef­fi­ca­cious in the con­struc­tion in­dus­try, par­tic­u­larly to pro­vide cru­cial sup­port for foun­da­tions, roads, and pave­ments. Soil compaction has gained wide­spread trac­tion over the past years, off­set­ting dis­tur­bances in­volved in dif­fer­ent con­struc­tion pro­cesses, which in­clude trench­ing, grad­ing, and ex­ca­vat­ing.

Along with the em­pha­sis on all-round vis­i­bil­ity and high-cen­trifu­gal forces, new gen­er­a­tion soil compaction ma­chines are be­ing in­te­grated with in­no­va­tive tech­nolo­gies such as fre­quency com­bi­na­tions, mul­ti­ple am­pli­tude, and dual-drum drive.

Con­trol au­to­ma­tion of soil compaction ma­chines has re­cently gained sig­nif­i­cant at­ten­tion by man­u­fac­tur­ers to re­solve chal­lenges linked with con­tin­u­ous mon­i­tor­ing. Ef­fec­tive meth­ods have been jus­ti­fied and sug­gested for var­i­ous con­struc­tion ap­pli­ca­tions, such as build­ing struc­ture foun­da­tions. The vi­bro­dy­namic method of sand and gravel ma­te­rial seal­ing, and con­tin­u­ous mon­i­tor­ing of soil compaction us­ing mea­sure­ment of am­pli­tudes, and fre­quency of har­monic os­cil­la­tions are prime ex­am­ples of such con­trol au­to­ma­tion ap­proaches.

Lack of au­to­matic con­trol in the de­gree of soil compaction and in­abil­ity to con­trol the work­ing mech­a­nism have fur­ther up­held the fo­cus and ef­forts on con­trol au­to­ma­tion of the soil compaction ma­chines. The fourth In­ter­na­tional Con­fer­ence on Ad­vanced En­gi­neer­ing and Tech­nol­ogy (ICAET) em­pha­sized on the devel­op­ment of al­go­rithms for au­to­matic op­ti­miza­tion of compaction.

Devel­op­ment of al­go­rithms would fur­ther un­der­gird the ap­pli­ca­tion of modern means of com­puter en­gi­neer­ing mi­cro-pro­cess­ing in sig­nal trans­mis­sion of vi­broa­cous­tic sen­sors, thereby al­le­vi­at­ing con­straints as­so­ci­ated with im­ple­men­ta­tion of au­to­matic con­trol sys­tem (ACS).

The­o­ret­i­cal analy­ses have de­picted con­trol au­to­ma­tion of soil compaction ma­chines to re­sult in over 25% in­crease in op­er­a­tional per­for­mance and out­put, in light of in­creased speed re­duced num­ber of passes in one grip. Im­ple­men­ta­tion of ACS will also en­able im­prove­ments in qual­ity of soil compaction, while cur­tail­ing con­sump­tion of lu­bri­cants and com­bustibles, and aban­don­ing tra­di­tional ap­proaches to con­trol of compaction de­gree.

Emerg­ing mar­kets hold im­mense po­ten­tial for the con­struc­tion sec­tor, which in­volves ro­bust uti­liza­tion of compaction tech­niques. Fo­cus on road con­struc­tion in these mar­kets has gained im­mense em­pha­sis over the re­cent years, with gov­ern­ments of coun­tries such as In­dia con­cen­trat­ing on con­struc­tion of world­class road net­work. In­vest­ments ear­marked for the road con­struc­tion have been paving huge op­por­tu­nity for OEMS.

Author­i­ties of road trans­port and high­ways are fo­cus­ing on im­ple­men­ta­tion of value en­gi­neer­ing pro­grams for pro­mot­ing use of new equip­ment, ma­te­ri­als and tech­nolo­gies in projects ex­e­cuted un­der pub­lic fund­ing mode. Key soil compaction ma­chines man­u­fac­tur­ers such as Hamm have in­tro­duced soil com­pactors built with patented de­signs, such as the three-point pen­du­lum ar­tic­u­lated joint, keep­ing in mind the op­er­a­tors’ ef­fi­ciency, safety and com­fort.

Built on sim­i­lar lines, Volvo’s SD110BA model fea­tures a con­ve­niently po­si­tioned con­trol sys­tem that en­ables easy con­di­tion­spe­cific switch­ing of work­ing modes. Vari­able drum fre­quen­cies pro­vided by the SD110BA fur­ther fa­cil­i­tates the op­er­a­tor to re­act faster to al­ter­ing soil con­di­tions and types. An­other ad­vanced soil compaction ma­chine in­tro­duced by JCB, the JCB116, is de­signed keep­ing the op­er­a­tor com­fort in mind, and fea­tures in-built, er­gonom­i­cally-placed compaction me­ter, which re­sults in pre­cise de­sired out­put. Heat lev­els and vi­bra­tions in JCB’S new range of soil compaction ma­chines are op­ti­mized to of­fer com­fort­able work­ing en­vi­ron­ment to op­er­a­tors.

These soil compaction ma­chine de­vel­op­ments have been de­signed to meet re­quire­ments of emerg­ing mar­kets, with ex­haust & en­gine emis­sion tech­nolo­gies to meet reg­u­la­tions and cool­ing sys­tems mod­i­fied to cope in ar­eas with ex­tremely high tem­per­a­ture fluc­tu­a­tions. With ma­jor play­ers such as JCB, Volvo, and Hamm gain­ing firm foothold in emerg­ing mar­kets, it is highly likely that these play­ers would eye fur­ther con­sol­i­da­tion of their pres­ence through devel­op­ment and launch of more ad­vanced soil compaction ma­chines.
