When overcoming the swamp, you need to know that the swamp can be reached if it is covered with thick grasses interspersed with sedge, in dry weather you can even drive through. If overgrowth of pine is visible in the swamp. If the swamp is covered with a continuous growth of moss and a thick layer (up to 30 cm) of tow of old, decomposed moss. It maintains the load of the machine on a caterpillar.
The order to overcome the swamp on the route, methods for determining the patency of a continuous peat swamp.
It is more difficult to pass any swamp if there are frequent puddles of stagnant water on it among the moss. One must make his way alone along the mossy strips and ridges overgrown with low bushes. If grass is growing in the swamp, on which, after flowering, fluff heads, like dandelions, remain. If the swamp is overgrown with dense shrubs, willow, alder, spruce or birch. It is almost impossible to pass the swamp if it is covered with reeds and if grass cover floats through the swamp. If the swamp is peaty, then you can determine its cross-country ability, being guided by the following table below.
Methods for determining the patency of a continuous peat bog.
|The nature of the grass cover||The method for determining patency of the swamp||Permissible pressure kg / cm3||Movement capability|
|Peat is very dense, drained or slightly moist.||When peat is compressed, a decrease in its volume is not felt in the hand, water is not released.||one||Car|
|Peat dense, medium moisture||When peat is compressed in the hand, a certain decrease in its volume is noticeable, water is released, but does not drain from the hand.||0.75||Car|
|Loose, moist peat||When peat is compressed in the hand, a significant decrease in its volume is noticeable, water is allocated in drops, peat is forced through fingers.||0.5||Machine tractor|
|Peat is very loose, very moist.||When peat is compressed in the hand, water flows out in a trickle, the mass is forced through fingers.||0.25||Man|
|Liquid peat, flowing||The mass is completely squeezed through the fingers.||0.12 – 0.14||Impassable|
You can check the thickness of the peat layer, its density and hardness of the soil using a metal pin with a diameter of 20 mm with notches after 10 cm. Passability of a continuous peat bog can be determined in the simplest ways..
, but hesitates under the feet of the walker. For safety reasons, moving along such a section of the swamp should be one at a time with an interval of 5-7 meters. In order to avoid rupture of the alloy, participants should not follow the trail. The sections of water encountered on the way need to be bypassed; this window is a gap in the alloy or a layer where it is very thin. The pit wells with bog water should also be bypassed..
For insurance, you must constantly keep the pole in a horizontal position at the ready. Fallen into a quagmire it is necessary to quickly pull up the pole to yourself and lie on it with your chest. If he himself is not able to rise, then he should not make unnecessary movements, so as not to further break the rafting. In this position, sharp and jerky movements must not be allowed and self-control must not be lost. Help to the fallen should be provided quickly, without fuss and at the same time carefully. First, you should fill the nearest place with poles and branches. Then, cautiously get close to him, help remove the backpack and get out.
Urea with a depth of 50 cm or more is better to pass through poles, which are successively stacked in the direction of movement. The sequence of stacking poles is that as they are released they are transferred forward. Thus, laying the hat, the group moves forward. You should walk along the slippery gati carefully, leaning as far as possible on the pole, with an added step or with the turn of the foot to the outside. If intelligence has established that the site of the swamp has solid soil under a layer of water, then you can move forward, track in trace of the lead. In any case, the movement should be smooth, insurance with a pole is required.
When moving through a swamp, you need to constantly monitor the direction, mark landmarks, set landmarks, tying small pieces of cloth or a bandage to them. Marking the path can also come in handy when returning back if it is impossible to move forward further. You need to go through the swamp in shoes and clothes. At the same time, trousers should be tucked so that they do not cling and do not interfere with walking..
Equipment, food and clothing should be packed in a plastic bag in the middle of the backpack. Before overcoming a swamp, it is necessary to learn as much as possible about it: where are the most marshy places, the possibility of getting around them, where are dry places (islands) in case of an unexpected stop.
