Background technology
During geotechnical engineering investigation, it is often necessary to building place pore-forming in advance and sampling, then to soil
Sample carries out a series of engineering mechanics parameter experiment, to judge engineering geology and the hydrogeologic condition in place,
Necessary parameter is provided for design and construction.Tradition Luoyang Spade is in investigation and prospecting, owing to its construction is convenient, behaviour
Make simple advantage to be widely used.If but in some place, use traditional Luoyang Spade, it may appear that with
Some restriction lower: first, needs to use the shovel head of not similar shape in the soil layer of different mechanics parameters, is so becoming
Hole operation may frequently be changed the shovel head of different model；Second, during carrying shovel, soil sample in shovel
Become that sample rate is the highest and easy to fall off, soil sample in disturbance hole；3rd, after carrying shovel, in hole, water content is too high
Soil layer can form a free seepage face, affect next step operation.Accordingly, it would be desirable to experienced prospecting
Personnel, revise the degree of depth and the integrity taking out soil sample under method based on certain reliability.
Therefore, in operation is reconnoitred in the place under different engineering geological hydrogeologic condition, need to be to Luoyang
Shovel exploration and forming hole method have claimed below: 1. shovel head is convenient, reliable, easy instrument can be utilized to carry out in scene
Revise；2. fetch earth into sample rate higher, improve work efficiency as far as possible；3. make sidewall in hole stable, Bu Zhi
Pore forming process is caved in.
Generally speaking, need to utilize existing reliable Luoyang Spade shovel head so that it can be widely applicable to various
Different engineering geology hydrogeologic conditions, carries out reliable pore-forming sampling process, comes Geotechnical Engineering with this
The problems such as prospecting and archaeological reconnaissance operation provide technical support.
Utility model content
The purpose of this utility model is to provide a kind of Luoyang Spade shovel head and forming hole method reliably.Utilize this side
Method, can the carrying out prospecting pore-forming operation of convenient and efficient, on the one hand evade owing to tradition Luoyang Spade shovel head is brought
Pore-forming efficiency and sampling efficiency are the highest, and after on the other hand having evaded top pore-forming, fetched earth in bottom by hole wall slump
Impact so that surveys more gears to actual circumstances.Simultaneously, it is possible to for archaeological work differentiates grave, bottom
Distribution provides technical support with the engineering problem caused.
This utility model is realized by following technical proposals.
A kind of Luoyang Spade with anti-tooth shovel head, including the arc shovel wall of ellipse half tubular be connected to
One shovel bar on shovel wall top, the medial wall along described shovel wall is evenly equipped with the skewed slot that several rows are anti-dentation,
Being connected to a ligule leading edge bottom shovel wall, this ligule leading edge and the junction of shovel wall arrange a ring-type oblique circle
Beam.
Further, described shovel masthead end is provided with ring-type button.
Further, the skewed slot of described anti-dentation is zigzag, and jagged bottom land is sharp tooth, groove face opening,
It it is plane between adjacent skewed slot.
Further, described skewed slot arcuately shovels direction, wall bottom.
Further, described ring-type oblique collar tie beam connects with shovel wall both sides of the edge, and oblique collar tie beam anchor ring is cross-section with shovel wall
Face is parallel.
Further, oblique collar tie beam anchor ring bottom is inclined plane.
Further, described ligule leading edge lower end head is tapered.
The utility model has the advantages that:
1. use anti-dentation oblique slot, on the one hand be more convenient for burying, on the other hand can increase contact surface when shadoof
Long-pending, strengthen side-friction force, it is simple to soil sample and the drawknot intensity that underlies between the soil body when sample is pulled out in opposing.
2. use " ligule " leading edge so that the big principal direction of stress of the shovel head contact soil body is close with plane of fracture angle,
Reduce damage of soil body face resistance, improve embedded depth.
3. use the shovel head of oval half tubular, improve the soil arching effect of sampling up-to-date style soil.
4. the oblique collar tie beam of different angles is set, soil sample and the frictional force of sidewall when improve shadoof.
5. during pore-forming operation, limit inspecting hole, limit setting of casing, protect the stability of upper portion side wall, simultaneously in reduction
Portion's soil body cave on bottom sampling impact.

Detailed description of the invention
With embodiment, utility model is described in further detail below in conjunction with the accompanying drawings, but is not intended as reality
By the novel foundation doing any restriction.
As it is shown in figure 1, a kind of Luoyang Spade with anti-tooth shovel head, including the arc of ellipse half tubular
Shovel wall 3 and the shovel bar 2 and the ring-type button 1 on shadoof top that are welded on shovel wall 3 top, shovel the interior of wall 3
It is evenly equipped with the skewed slot 4 that several rows are anti-dentation on sidewall, is simultaneously included in one ligule leading edge of spreading bottom shovel head
6, this ligule leading edge 6 arranges a ring-type oblique collar tie beam 5 with the junction of shovel wall 3.Ring-type oblique collar tie beam 5
Connecting with arc shovel wall 3 both sides of the edge, oblique collar tie beam anchor ring is parallel, as shown in Figure 2, tiltedly with shovel wall transverse section
Collar tie beam anchor ring bottom is inclined plane, as shown in Figure 3.Ligule leading edge 6 lower end head is tapered.
Wherein, as shown in Figure 4, the skewed slot 4 of anti-dentation is zigzag, and jagged bottom land is sharp tooth,
Groove face opening, is plane between adjacent skewed slot.Skewed slot arcuately shovels direction, wall 3 bottom.
Shovel wall 3 stack shell of this device can arrange the different ratios of shaft diameter in length and breadth, different angles and the sidewall of the degree of depth
On anti-teeth groove, the oblique collar tie beam of different angles, and the extension elongation of different ligule leading edge and angle.
At a shadoof 2 and the ring-type button 1 on shadoof top at shovel head top, rope can be tied up to spreading on 1
Shadoof；During inspecting hole, by manpower, shovel head is vertically stood in ground, place, by injection ground, ligule leading edge
Insert and carry certain distance under the degree of depth of ground in advance, and within one week, carry out injection along this inspecting hole, propose ground subsequently,
Along with the increase of depth of penetration, progressively ready made pvc pipe is put into hole, to protect wall stability.
The principle of this device is, has transformed the shape system of traditional Luoyang Spade shovel head, when pore-forming, has set shovel head
Put ligule leading edge and anti-dentation skewed slot, on the one hand when injection, the injection soil body is separated with the soil body that gets sample, has
Beneficially ligule leading edge is more convenient and reliable cutting with surrounding soil by the soil body in hole is come.On the other hand passing through
Fashionable, anti-dentation skewed slot is extruded by soil sample, increases sidewall friction power when being more beneficial for getting sample.3rd, tiltedly
Collar tie beam is an oblique inside steel collar tie beam, so when injection, is also beneficial to the injection soil body, is pulling out sample
Time, it is more convenient for breaking the connection between soil sample and the bottom soil body, when getting sample, increases lateral resistance,
Improve sampling yield rate.
The prefabricated pvc pipe of some length is set simultaneously, is progressively placed in hole with the increase of depth of penetration,
Ensure the stability of hole wall, can effectively evade the complex situations in place.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model
It is not limited thereto, the technical scope that any those familiar with the art discloses at this utility model
In, the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.
