Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the preventer front view of this utility model embodiment；
Fig. 2 is the preventer left view of this utility model embodiment；
Fig. 3 is the A-A sectional views of the preventer left view of this utility model embodiment.
Specific embodiment
With reference to Fig. 1～Fig. 3, this utility model is a kind of preventer of underground utilities exploration drilling cutting, and preventer includes
Two pieces of steel plates 1, the inner support component of support both sides steel plate 1 and two steel plate doors being arranged on the inside of two steel plates 1, also include using
In the hanger 2 of boom hoisting.
Steel plate 1 is main assembled by more than two pieces of steel plate member, and weld seam adopts two-sided welding, finally makes monoblock steel plate
1 long 4.5m, high 3m and thickness 10mm.Then in two blocks of steel plates 1 away from the opening that cut lengths at the 0.3m of bottom are 1.5m × 1m
3；3 in the vertical directions that are open are placed in the middle, make preventer symmetrical, and center of gravity is placed in the middle, are easy to preventer stable by deadweight
Sink.Hanger 2 is symmetrical along central vertical axis simultaneously, welds with steel plate 1.
Inner support component is mainly made up of the seamless steel pipe 4 of external diameter 48mm, wall thickness 3.5mm, for supporting two steel plates of left and right
1, steel plate 1 or so withstands leads inner wall and prevents digging from collapsing.Seamless steel pipe 4 between two steel plates 1, the quincunx cloth in spacing 1m
Put, but be 0.4m in preventer both sides spacing, as shown in Figure 3；Ensure that the installation site of seamless steel pipe 4 is avoided steel plate door and opened
Close scope, i.e. seamless steel pipe 4 to be mainly disposed to above the left and right edges and steel plate door of steel plate 1.To improve steel plate 1 and seamless steel pipe
Installation strength between 4, is bent into rectangular shaped using the reinforcing bar of diameter 16mm, as reinforcement welded lap steel plate 1 with it is seamless
Steel pipe 4.
Steel plate door is opened and closed by the way of horizontally slipping, it is ensured that steel plate door covers opening completely.Four pieces of 5 sizes of sliding door are
0.85m × 1.2m, each sliding door 5 is provided with a pair roller 7 and one group of handle is easy to drag；In 1 top and the bottom of steel plate correspondence position
The chute 6 for being equipped with that guiding sliding door 5 slides is installed, top chute 6 is the gap of two angle steel composition, acts primarily as the effect of guiding；
Bottom chute 6 raises up for angle steel rib, the contoured fit with roller 7, plays a part of to support, guides.
A kind of underground utilities exploration drilling cutting method using above-mentioned preventer, its methods ＆＆ steps of implementation are as follows：
1）, according to plan construction lead wall, its reach design concrete strength before, using reinforced concrete structure covering curing
And temporary support is done with the lumps of wood；
2）, preventer be put into reach leading within the walls for prescribed strength, workmen is uniformly excavated in preventer or so,
Preventer is made to sink with deadweight；
3）, when exposing at the top of pipeline, abolish pipeline, evacuate gas in liquid in pipe and drain, continue thereafter with excavation
To pipeline bottom；
4）, open preventer sliding door 5, using air determinator determine abolish after pipeline in air, it is determined that nothing
After harmful gass are present, workmen blocks pipeline according to design requirement；
5）, treat pipeline closure after the completion of take out preventer, diaphram wall of next constructing.
The high 1.7m of wall is led in design and construction, leads clear distance 0.8m between wall, using C20 reinforced concrete structures.Above-mentioned size is
It is corresponding with preventer size.Certainly, after preventer size is changed, which is led wall size and is also required to redesign.Leading wall
After concrete reaches prescribed strength, preventer is put into by hanger 2 using wheeled crane and is led within the walls, and each is anti-
Protection unit matches somebody with somebody two workmens.
Workmen removes and leads at the top of pipeline within the walls after earthing, and left and right is uniformly excavated, and enables preventer uniformly to sink；
Ensure that preventer two ends soil face is higher than intermediate line simultaneously, excavated after pipeline again the two ends earthwork to abolish below.Work as protection
When device sinks to touching at the top of pipeline, select after distinguishing pipeline material and abolish instrument:Mix if brick or armored concrete knot
Structure is directly abolished using pneumatic pick；Then cut using acetylene cutting machine if steel-tube construction.Gas in liquid in pipe and drain is evacuated,
With excavating and cutting advanced depth, preventer meeting nature sinks until pipeline bottom.
The sliding door 5 of preventer bottom after the completion of pipeline box culvert is abolished, is opened, gap is firstly appeared out from, is determined using air
Device determines inner air tube, it is determined that workmen could enter pipeline after existing without harmful gass.Plugging material is hung by loop wheel machine
Enter to lead within the walls, the mouth of pipe is blocked according to design requirement, it is ensured that serosity does not outflow during subsequent construction diaphram wall, prevents mud from passing through
Pipeline outflow polluted underground water resource.Treat that pipeline closure is completed, hang out preventer, guide pours into the mud for having prepared within the walls
Slurry, diaphram wall of constructing.
This utility model can realize pipeline safety cutting and the closure led in the range of 4.5m within the walls of constructing.
Certainly, this utility model is created and is not limited to above-mentioned embodiment, and those of ordinary skill in the art are not disobeying
Equivalent variations or replacement can also be made on the premise of back of the body this utility model spirit, the modification of these equivalents or replacement are all contained in this
In application claim limited range.
