The process of taking the Party ‘s anniversary date (3 months 2) start . According to the blueprint , the tunnels are built based on previous experience , by creating a well kept about 16m diameter 0.6 m , 3 m deep , the mouth of the adjacent eyelid . From the bottom of deep wells drilled picks used to create tunnels with 50cm width , 80cm height . Tunnels in the corner of the last fight , has followed from the tunnel to the other tunnel into the continuum is a very scientific calculations . So there are short cuts , with parallel sections , intersection , under the paragraph above , within crooked , winding , extending to over 100 kilometers .
Structures Cu Chi Tunnels
The confluence or coming into the mouth tunnel , tunnel narrowing , sometimes to crawl or creep into the mouth tunnel . The intersection of the tunnels have special safety latch . Fasteners is a piece of wood , long spikes or rubber block is 40cm long wire diameter . To seal the tunnels just tug rope , rubber knots , or log sealed road will narrow tunnels . Safety latches to prevent enemy use tear gas or water pump poison into the tunnel .
The mouth of the tunnel is a special structure , often very sophisticated mix of bushes , termite mound , just the right size to get into a 30cm x 40cm . Hatches are 10cm thick piece of wood , the grass strip , just shoot tunnel mouth . These vents are created by 45o oblique lines , hiding in the bushes hard to detect . At the tunnel mouth down , anti- trap sometimes , a plank crossing , as set booby traps . The stranger walked up , immediately fell down traps .

First conceived as a cellar hole , par 2m , 3.5 m wide , 3.5 m deep ( including the tunnel roof 1.8 m above the ground ) .
Tunnel roof is made of concrete drop horizontal momentum , then completely fill the above. In the basement , the two walls are load-bearing truss -shaped tree can have five . Some tunnels are waterproof cement plaster . Tunnel mouth usually connected through a tunnel checkpoints . From here , the tunnels have forked fork . A long tunnel leads to special edge and bear up the Saigon River in the holly bush . When there is effective security , boat across the river to receive special guests will be on the basis Thanh Tuyen ( across the river in Binh Duong Saigon ) .

During tunnel shelters in Phu My Hung , comrade senior leaders often visited the tunnels off , conversations with people in the village as well as his family and Eight Cut two newspapers . Left the immediate area of the room announced Glory battalion with less number of tunnels , underground structures such common administrative , size 3m x 3.5 m . A solid battle lines forming a protective arc center is a system of alternating trenches fighting emplacements .
Deep trenches from 1.2 m to 1.4 m , 0.5 m horizontally , running on terrain ders and fighting techniques and broken or followed the fight mound . Pros use fire fighting aircraft of 3m diameter circular ditch surrounding the mound higher than the person in the middle . The gunner has placed mounds used guns , just as an obstacle , running around the mound hiding shoot enemy planes . There is fighting pit mounds contain from 3 to 5 people . The gunner layout multifaceted fight . In the Cu Chi tunnels are a parallel trenches layout roads 6 more dock fighter , equipped to trick the enemy firepower , lure the enemy , the enemy intercept and destroy the enemy .
