The utility model discloses it has following advantage to compare prior art: the utility model provides a during geotechnical test preparation sand sample, the problem of not scraping the specialized tool on colored dry sand surface, not only the scratch is regular, moreover simple structure, the operation of being convenient for.

Description

A kind of instrument for scratching sand face

Technical field

The utility model relates to a kind of soil test device, particularly relate to a kind of work for scratching sand face Tool.

Background technology

When sand sample is prepared in soil test, in order to make sample density uniform, it is commonly used in certain die trial volume built-in The method of corresponding dry sand amount (depending on the density controlled) controls.Generally will calculate by predetermined density and volume and claim The dry sand taken is divided into 5～6 equal portions, is inserted in die trial successively by every part of dry sand, and suitably rams make with ramming rod The thickness of every layer of dry sand reaches pre-provisioning request, for eliminating the layering between soil sample, before inserting next layer of dry sand, Preceding layer dry sand surface is scratched.Scratching sand face currently without special instrument, testing crew is the most voluntarily Select tool, and rule of thumb operate, this results in the sand face after every layer of dry sand scratches and comes in every shape, impact examination The uniformity of sample.

Summary of the invention

When the purpose of this utility model is to overcome current soil test to prepare sand sample, do not scratch dry sand table The problem of the specific purpose tool in face, invents a kind of instrument for scratching sand face.

This utility model is achieved through the following technical solutions:

A kind of instrument for scratching sand face, mainly by montant, Anti-slip cover with scrape head and form, it is characterised in that: Described montant is made up of upper bar, middle part bar and lower pole sequentially compact siro spinning technology, described upper bar, middle part bar and Lower pole is solid cylinder, and lower pole is provided with external screw thread, and described Anti-slip cover is hollow cylinder, and Be tightly sleeved in the upper bar of montant, described in scrape head and formed by scraping teeth and sleeve compact siro spinning technology, and be tightly sleeved On the lower pole of montant, on the female thread being provided with in female thread, and sleeve in described sleeve and lower pole outside Screw thread is suitable.

Aerolite is used as the preferred implementation of above-mentioned art scheme, described montant and the material scraping head.

As the preferred implementation of technique scheme, the material of described Anti-slip cover uses silica gel.

This utility model has the advantage that compared to existing technology

A kind of instrument for scratching sand face, this utility model solves soil test when preparing sand sample, does not has The problem having the specific purpose tool scratching dry sand surface, not only scratch is regular, and simple in construction, convenient to operate.

Detailed description of the invention

Elaborating embodiment of the present utility model below, the present embodiment is with technical solutions of the utility model Implement under premised on, give detailed embodiment and concrete operating process, but of the present utility model Protection domain is not limited to following embodiment.

See Fig. 1 to Fig. 5, a kind of instrument for scratching sand face that the present embodiment provides, as it is shown in figure 1, Mainly by montant 1, Anti-slip cover 2 with scrape 3 and form, it is characterised in that: described montant 1 by upper bar 11, Middle part bar 12 and lower pole 13 sequentially compact siro spinning technology composition, described upper bar 11, middle part bar 12 and bottom Bar 13 is solid cylinder, and lower pole 13 is provided with external screw thread, and described Anti-slip cover 2 is hollow cylinder Body, and being tightly sleeved in the upper bar 11 of montant 1, described in scrape 3 tight by scraping teeth 31 and sleeve 32 Close it is formed by connecting, and is tightly sleeved on the lower pole 13 of montant 1.It is provided with female thread in described sleeve 32, And the female thread in sleeve 32 is suitable with the external screw thread on lower pole 13.This utility model is controlled during use Montant 1 vertically, put down gently and scrape 3 in having hit the dry sand surface of actual arrival predetermined thickness, keep montant 1 to erect Slowly rotate this utility model 180 degree while Zhi, the most upwards propose this utility model, the most visible dry There is regular concentric circles scratch on sand surface.

As the preferred implementation of above-mentioned art scheme, described montant 1 and scrape the material of 3 and all use aviation Aluminium alloy.

As the preferred implementation of technique scheme, the material of described Anti-slip cover 2 uses silica gel.

These are only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this Within the protection domain of utility model.
