Abstract
The utility model relates to a kind of mud extractor, comprise cylinder barrel, the second lifting rope and sleeve pull bar, the top of cylinder barrel is by sleeve pull bar and the second lifting rope traction upper and lower displacement, it is characterized in that, the center of top of described cylinder barrel is provided with mud inlet, be provided with the mud suitable with mud inlet in described cylinder barrel to seal, described mud sealing center upright is fixed with sealing pull bar, described sealing pull bar draws upper and lower displacement by the first lifting rope, the bottom center of cylinder barrel is provided with lift heavy screw rod, lift heavy screw rod is furnished with ring-shaped weight block.This mud extractor, can transfer to the different depth of slurries, and synchronously completes perfusion and the sealing of slurries, ensures the independence of these degree of depth slurries.The counterweight of slurries extractor can also be increased simultaneously according to the degree of depth of extraction slurries, density and suffered buoyancy size, ensure that mud extractor can sink to designated depth, thus complete the extraction work of different depth place mud.
Description
[technical field]
The utility model relates to mud extraction element technical field, specifically a kind of mud extractor.
[background technology]
Mud extractor is used to a kind of utensil extracting mud, during mud parameter when being mainly used in the foundation pile pore-forming of civil engineering detects.In civil engineering pile foundation construction, pouring pile hole often adopts the method for mud off, and the proportioning parameter of mud has much relations to pouring pile hole and Forming Quality, mud parameter is detected to the important means becoming quality Control of Bored Pile.For this reason, in foundation pile pore-forming, how to obtain mud and become in engineering faced by having to problem.The method in the past adopted arbitrarily adopts a container on Starch Level, to get some as detection slurries, but the method can only get the sample of slurries surface layer, can not get the slurry samples at different depth place.
[summary of the invention]
The purpose of this utility model is the defect overcoming prior art existence, provides a kind of mud extractor of new structure.
For achieving the above object, design a kind of mud extractor, comprise cylinder barrel, the second lifting rope and sleeve pull bar, the top of cylinder barrel is by sleeve pull bar and the second lifting rope traction upper and lower displacement, it is characterized in that, the center of top of described cylinder barrel is provided with mud inlet, be provided with the mud suitable with mud inlet in described cylinder barrel to seal, described mud sealing center upright is fixed with sealing pull bar, described sealing pull bar draws upper and lower displacement by the first lifting rope, the bottom center of cylinder barrel is provided with lift heavy screw rod, lift heavy screw rod is furnished with ring-shaped weight block.
Periphery wall along cylinder barrel is provided with some protection floors at equal intervals, makes cylinder barrel with there being certain safe distance between drill hole wall.
Described lift heavy screw rod and adopt demountable structure between balancing weight and the bottom of cylinder barrel.
I takes charge of the mud extractor of utility model, can transfer to the different depth of slurries, and synchronously completes perfusion and the sealing of slurries, ensures the independence of these degree of depth slurries.The counterweight of slurries extractor can also be increased simultaneously according to the degree of depth of extraction slurries, density and suffered buoyancy size, ensure that mud extractor can sink to designated depth, thus complete the extraction work of different depth place mud.

[detailed description of the invention]
Now by reference to the accompanying drawings and embodiment the technical solution of the utility model is further elaborated, believe it is clearly for a person skilled in the art.
As shown in Figure 1, a kind of mud extractor, comprise cylinder barrel 6, second lifting rope 2 and sleeve pull bar 3, upper and lower displacement is drawn by sleeve pull bar 3 and the second lifting rope 2 in the top of cylinder barrel 6, it is characterized in that, the center of top of described cylinder barrel 6 is provided with mud inlet, be provided with the mud suitable with mud inlet in described cylinder barrel 6 and seal 5, described mud seals 5 center upright and is fixed with sealing pull bar 4, described sealing pull bar 4 draws upper and lower displacement by the first lifting rope 1, the bottom center of cylinder barrel 6 is provided with lift heavy screw rod 8, lift heavy screw rod 8 is furnished with ring-shaped weight block 9.
As shown in Figure 2, the periphery wall along cylinder barrel 6 is provided with some protection floors 7 at equal intervals, makes cylinder barrel 6 with there being certain safe distance between drill hole wall.
Demountable structure is adopted between the bottom of described lift heavy screw rod 8 and balancing weight 9 and cylinder barrel 6.
As shown in Figure 3, the extracting method of above-mentioned mud extractor, is characterized in that, by following steps:
Step 1, the balancing weight 9 of corresponding weight is mated according to descending depth, strain the first lifting rope 1, then sealing pull bar 4 is carried on, make mud seal 5 to be close to mud inlet, realize mud inlet and be tamping, ensure not enter slurry in cylinder barrel 6 in decline process, progressively transfer the second lifting rope 2, cylinder barrel 6 slowly drops under Gravitative Loads specifies grouting position;
Step 2, unclamps the first lifting rope 1, strains the second lifting rope 2, and mud sealing 5 is opened under stress, makes this position mud flow to cylinder barrel 6, completes grouting;
Step 3, strains the first lifting rope 1, unclamps the second lifting rope 2, and make mud seal 5 and be again tamping, lifting, takes out mud.
First lifting rope 1, sealing pull bar 4 and mud sealing 5 are linked together, achieving mud extractor transferring and automatic plugging to cylinder barrel in uphill process, outside slurries can not be entered in cylinder barrel, ensure that institute's slurries independence of getting and pure property in cylinder barrel.
Along some protection floors 7 that the periphery wall of cylinder barrel 6 is provided with at equal intervals; make cylinder barrel 6 with there being certain safe distance between drill hole wall; the slurries obtained are made to be positioned at the centre position in hole; make got slurries have certain representativeness, simultaneously also prevent from caving near hole wall and cause cylinder barrel to block or by pile things on.
Adopt demountable structure between the bottom of described lift heavy screw rod 8 and balancing weight 9 and cylinder barrel 6, change according to appointment descending depth.Making mud extractor can increase the deadweight of slurries extractor according to getting the degree of depth of slurries, density and suffered buoyancy size, ensureing that mud extractor can sink to designated depth, thus completing the extraction work of different depth place mud.
