Requirement that should be in crevasse different in width to the different tensile forces of steel wire rope.Selected pile-type is had to according to crevasse width, dykes and dams soil
The actual conditions reasonable selections such as matter, field condition, experience speciality.The characteristics of below with regard to several pile-type and its method of construction
It is described below：
(1) light automotive stake：Heavy motor vehicles are utilized respectively at the top of the dykes and dams of crevasse both sides as pile body (such as crawler type
Excavator, crawler dozer etc.), recycle the power of the heavy vehicle as the tensile force of steel wire rope.This advantage is
It easily sets up, is time saving and energy saving；The disadvantage is that lasting stability is poor, tensile force is smaller, also to occupy large scale equipment.It is adapted to crevasse
Relatively narrow situation (crevasse is less than 30m).
(2) medium-sized driven pile：Metallic rod is squeezed into as pile body into dike at the top of the dykes and dams of crevasse both sides.It is recommended that metalline stake
Diameter should select>The excellent medium carbon steel rod iron of the cylindrical, solid of 100mm, tip, comprehensive mechanical performance, piling bar are squeezed into deep in dike
Degree is more than 1000mm.The advantages of this stake is that bearing capacity is bigger than light automotive stake, and stability is good, is not take up miscellaneous equipment；It lacks
Point is that hand spike is more time-consuming.Solve the problems, such as the pre-manufactured hole before piling with regard to more preferable as being equipped with special small drilling machine
.It is adapted to the case where medium-width crevasse (crevasse 30-50m).
(3) heavy melt pit stake：In crevasse both sides, dykes and dams top down digs one and is about 1m, width about 0.6m, depth about 0.6m
Hole, length direction and the crevasse sides aligned parallel in hole.Hole is put into the original of about 800mm one section long, diameter about 400mm in hole after digging well
Juggle, the horizontal centre for lying in this log of steel wire rope i.e. pile.The operation principle of melt pit stake is：When steel wire tensioning, pulling force passes
To log, log converts pulling force to the pressure to crater wall.Since log surface area is very big, pretend with the unit pressure in crater wall
Power can very little.This allows soft dike soil also to have prodigious bearing capacity.The advantages of melt pit stake is bearing capacity far above light-duty
Motor-driven stake and medium-sized driven pile, therefore it is adapted to that crevasse is wider, the more demanding situation (crevasse of steel wire tensioning power>50m)；
It is adapted to that dykes and dams soil property is too soft, is unfavorable for the special circumstances that driven pile establishes stable bearing capacity.Its shortcomings that is manpower
It digs pit more time-consuming.
Two tensioning steel wire ropes building courses be specially：
After stress anchor picket 3 is built, steel wire rope draws into steel wire loop with U-shaped card, according to connecting steel wire rope shown in Fig. 1
Stretcher rear enclosure is on built anchor picket.Finally by steel wire rope tensioning device by loose steel wire tensioning, two are tensioned steel
Cord is built and is finished.The tensioning steel wire rope built should meet following requirement：
(1) two steel wire rope keeping parallelism, and its width L meets the requirements.
(2) (prefabricated water fender quantity used is different) of different size according to crevasse, two steel wire tensioning degree are appropriate.
(3) in order to improve steel wire rope bearing capacity and reduce tensile force to the destructive bending moment force of anchor picket, steel wire rope
Set should be close to dykes and dams ground.
Light prefabricated water fender queue is built：
As shown in figure 4, being skeleton 11 with hollow steel profile, position, the facility of support ring and serializer are prefabricated on skeleton；
11 surface of skeleton is covered with color steel tile material.Light prefabricated special rectangle water fender is the specification after factory is manufactured by seriation
It is stored in flood fighting material depot.Using hollow steel profile do skeleton 11 be in order to improve bending resistance of the skeleton in stress and
Mitigate weight and is convenient for manpower transport.When blocking crevasse, which transports to tiling behind crevasse scene and is arranged in two tensionings
Parallel steel wire rope on carry out set of queues dress, on Special series device 9 reliably series connection between every two pieces of prefabricated water fenders；Every piece pre-
Support ring 10 on water fender processed is slidably connected with supporting steel-cable also reliable assembling.Water fender queue is in the flat of crevasse side
It is gradually pulled and is slid to crevasse opposite bank along tensioning steel wire rope from traction rope while assembly on row steel wire rope.When prefabricated water fender
Queue is when simultaneously Landfill covering lives entire crevasse for sliding on two steel wire ropes, prefabricated water fender queue length is less than crevasse width
5-10cm or so, up and down to just, prefabricated water fender queue is accused and is built up.
The foundation of prefabricated baffle wall：
The prefabricated water fender queue 7 above crevasse by " water fender queue width be less than crevasse 5-10cm of width, on
Under to just " build up, after errorless on inspection, under unified commander, simultaneously, synchronize the stretcher for loosening and launching steel wire rope both ends,
So that one whole of prefabricated water fender queue being put on dispensing steel wire rope is accurately submerged in water, touches the bottom.In this way, prefabricated water blocking
Plate queue as wall (oblique is hung on supporting steel-cable, it is heavy at one end enter the bottom, stood in crevasse flood at skewed),
The flood that breaches a dyke in crevasse is carried out blocking closure.Prefabricated baffle wall, which is established, to be completed.So far crevasse main task is blocked to complete.
Follow-up work after crevasse closure：
(1) after the prefabricated baffle wall is built up, the main flood in crevasse has been truncated closure, but may also have one
A little smaller holes, hole, gap are also in leak.At this moment ready leak stopping water fender, straw bundle, plastic film and other material pair can be used
