Masiku ano, ndi chitukuko cha zachuma komanso zofuna za anthu za mayendedwe, mzinda uliwonse ukumanga njanji yapansi panthaka,Larsen zitsulo pepala muluziyenera kukhala zomangira zofunika pomanga njanji yapansi panthaka.
Larsen zitsulo pepala muluali ndi mphamvu zambiri, kugwirizana kolimba pakati pa mulu ndi mulu, zotsatira zabwino zolekanitsa madzi, ndipo zingagwiritsidwenso ntchito. Mitundu yodziwika bwino ya milu yachitsulo imakhala yooneka ngati U kapena Z. Milu yazitsulo zooneka ngati U imagwiritsidwa ntchito pomanga njanji zapansi panthaka ku China. Njira zake zomira ndi zochotsera, kugwiritsa ntchito makina ndi zofanana ndi mulu wachitsulo wa I-zitsulo, koma njira yake yomanga ingagawidwe kukhala imodzi-wosanjikiza zitsulo pepala mulu cofferdam, awiri wosanjikiza zitsulo pepala mulu cofferdam ndi chophimba. Chifukwa cha dzenje lakuya la maziko pakumanga njanji yapansi panthaka, kuti zitsimikizire kukhazikika kwake komanso kumangidwe kosavuta, ndikupangitsa kuti ikhale yotsekedwa ndi kutsekedwa, mawonekedwe a skrini amagwiritsidwa ntchito kwambiri.
Larsen zitsulo pepala mulu kutalika 12m, 15m, 18m, etc., njira zitsulo pepala mulu mulu kutalika 6 ~ 9m, chitsanzo ndi kutalika anatsimikiza ndi mawerengedwe. Mulu wachitsulo wachitsulo umakhala wokhazikika bwino. Ntchito yomanga dzenje ikamalizidwa, mulu wazitsulo wachitsulo ukhoza kukokedwa ndikusinthidwanso. Kumanga kosavuta ndi nthawi yochepa yomanga; Mulu wazitsulo wachitsulo sungathe kuletsa madzi, m'dera lapamwamba la madzi apansi, kudzipatula kwamadzi kapena miyeso ya mpweya iyenera kuchitidwa. Mulu wachitsulo wachitsulo uli ndi mphamvu yopindika yofooka, yomwe imagwiritsidwa ntchito kwambiri ngati dzenje la maziko kapena ngalande ndikuya ≤4m, ndipo nangula wothandizira kapena kukoka ayenera kukhazikitsidwa pamwamba. Kuuma kwa chithandizo ndi kochepa ndipo kusinthika pambuyo pofukula kumakhala kwakukulu. Chifukwa cha mphamvu yopindika yolimba, mulu wachitsulo wa Larsen umagwiritsidwa ntchito kwambiri popanga dzenje lakuya la 5m~8m lokhala ndi zofunikira zochepa zachilengedwe, kutengera chithandizo (koka nangula).
