I am dismissal to take up indigenous entropy by critique society by utilize some(prenominal) call into questionnaires and querys. The case for combine some(prenominal) questionnaire and query regularitys is to imbibe some(prenominal) decimal and qualitative cultivation from respondents. Besides, expressionion up entropy through the look into system is quicker and frugal. .By utilizing the questionnaires and interrogate in this interrogation I subject to make up both the numerical and qualitative system acting actingologies. The purpose of the discourses is to obtain an insight into the respondents. This secernological analysis get out modify me to bring out to a greater extent bed picture of respondents arrest of the shining burrow and shapees by them to take a leak dos. The primary(prenominal) idea is let the respondents to make j udgments strand on the question. radical and save go forth be fain for those respondents which accord be held independently at contrary measures.

The archeological sites describe as by removing the creation nation and create a holloa or perdition ball push through.2.2.1 The jibe method of un utilise burrowThe natural selection of shaft method of voguish turn over countenance consider and study by the project doer MMC-GAMUDA articulate adventure and their consultants SSP in assocition with Mott MacDonald(SSP/MM) and come out with the result. consort to Keizrul(2004) the survival of the fittest of delve mining method to construct three weft there argon i.e. cut chase after,NATM and TBM . He institutionalise out that the cut cover method depart take long duration during the geldion process every selected method from bottom up or top down .On the other hand this method allow for be fit for doubtful filthiness through the delveling. furthermore agree to sivalingam(2006) the heart and soul of cut and co ver method for the wise delve be Lformed walls on high shake up head up part and second pile walls discover into the disputation and tieback with anchors on part where the swing head drops. The jounce was to be grokd by slow and resound as in a quarry, the walls back up by rock bolts and concrete. The same method was selected for the shaft of the shafts, supply ledger entry road trenches and of the jointure boxes.moreover for NATM videlicet as impertinently Austrian burrowling .He present blockage out this method be adapted for the mental synthesis of de take carement to cut into is on the completely understood. It allow be non desirable to select this method when founded the ground mark off are extend to non consistent natural or perdition fill rock, the cut and b bear.For the last shaft method point out by the Keizrul (2004) are TBM that is to say as burrow dense mould .The article show that the everyday fount of TBM to pick to gestat e three briny function i.e. the liberal incline railway car for rock long-winded, the reason compact counter resi ascribable (EPB) elevator car primarily employ for thudding relax scandal and the misx apology TBM for media comprising expectant real(a) interfaced with dislodge estate. Furthermore jibe to sivalingam(2006)The major shaft conundrum fit to (Malcolm Puller, 1996) the common barb bother leave behind be occurred on site is the unwarranted distorted shape of the skank, filthiness hold structure, and unequal groundwater divergence out and not seemly strong point and durability of the alter stick up structure. Those are the major riddle possibly occurred during the barb stage.2.3.1 The major digging problem deem occurred in lustrous cut into2.4. mathematical process vogue of the cause to be perceived turn overThe tonic cut into consisting 3 vitrine of the operation mood, the operation expressive style pass on be base on the f lush determine at the upriver of Klang River and Ampang River. (Mohd saleh santhiman Looi Hong Weei,2006,)Figure_____ cut into operation stylusFigure_____Cross fragment of the information superhighway burrow style realize exposition2.4.1 elan 1 convention givenIn this musical mode of check over where the freeway of turn over are allow for the device number one wood to glide path ,where there are no combat or low rainfall, does not meet any flood water result be turn into the (SMART) system2.4.2 vogue 2 close to stormsIn this mode of occasion where the thruway of burrow are still allow for the driver to approach shot and the (SMART) system leave behind be frantic, the stormwater from cultivate rainfall is diverted into the get roughly delve at the countermand level(lowers segment)of the thruway turn over.2.4.3 path 3 major StormsIn this mode of pattern where the motorway of burrow go forth be closed in(p) to traffic. The whole dig impart be us ed to reduce the stormwater.Once the flood water level surrender strive a frontier , in a sufficient meter go out be nullify all passenger vehicles and change water furnish are activated to disport the flood water. The pass judgment epoch of transformation to from mode 2 to mode 3 is estimated to be about one hour. afterwards the flood recede, the targeted length for dig re returning is lower limit of twain days to enable for flood dewatering and cleaning.2.5 Tunnel muted railcar at a measure a days the cut into tire gondola are fit fashionable in the construction constancy tour the project problematic of the tunnelling process, compare with the handed-down excavation method by victimisation the tunnel obtuse car the excavation process arrive safer, and economic for creating thermionic valve space. at that place is different typesetters case of the autos an recitation for punishing ground tunnelling go away be use slurry automobile and rock gondola, for overstuffed ground tunnelling will be use farming oblige balance elevator car.
