Abstract

The utility model discloses a rock core vacuum storage device. A barrel body (1) is provided with a barrel cover (2) and a candle (3) for sealing the barrel cover (2) and the barrel body (1), super-fine sand (4) is arranged inside the barrel body (1), and the position between the barrel body (1) and a rock core (5) is filled with the super-fine sand (4) when the rock core (5) is arranged inside the barrel body (1). The super-fine sand must be dried before being used, and the moisture content of the super-fine sand is lowered as much as possible; in addition, the dried super-fine sand must be arranged at the bottom of the barrel body before the rock core is arranged inside the barrel body, and besides the conditions, the interior of the device can approach the vacuum state by filling the whole paint barrel body and a groove of the barrel cover with molten candle block liquid.

Description

Core vacuum save set

Technical field

The utility model relates to a kind of vacuum save set, particularly relates to a kind of architecture foundation pile core vacuum save set.

Background technology

Current national building operation launches on a large scale, in construction process in early stage, all can relate to the construction of basic branch.Under regular situation, the construction of basis branch, the each side that takes part in building generally all can extract by a certain percentage foundation pile core and detect its compressive strength as judging the whether qualified foundation of building bearing stratum bearing capacity using unit in charge of construction, unit in charge of construction extracts core and sends institute's this process of resistance to compression that detects with charge free, it is an important step of core Strength Changes (reduction), if it is improper that this link core is preserved, core Strength Changes (reduction) is excessive, to cause core lower compressive strength, thereby mislead unit in charge of construction and continue excavation foundation, to cause basis super dark, waste resource, the cost of building is also by meaningless raising.Under regular situation, unit in charge of construction can take to paste Seal and preservation and carrying with plastic sheeting and transparent adhesive tape, such store method, there is following defect: the one, preservation safety is very low, plastic sheeting is extremely easily damaged, cause core to contact with natural air, thereby weathering core also causes core strength decreased, the 2nd, carry extremely inconvenient, be transported to office or laboratory from camp site, all will repeatedly carry, plastic sheeting all will be subject to the extruding of core, thereby it is bad to cause plastics to broadcast wearing and tearing, affects core intensity; The 3rd, cannot repeat turnover utilization, plastic sheeting is merely able to use once reluctantly, and after core is sent to laboratory, plastic sheeting just will be torn to shreds, cannot have enough to meet the need recycling, out of reach green construction object; The 4th, produce a large amount of non-degradable rubbish, plastic sheeting just becomes rubbish after using, and plastic garbage non-degradable also cannot recycle, and generally adopts burning disposal, produces a large amount of toxic and harmfuls.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of core vacuum save set that can allow the core of foundation pile taking-up can approach as much as possible bearing stratum core intensity in the time of resistance to compression.

For solving the problems of the technologies described above, the core vacuum save set that the utility model provides, staving is provided with bung and by the candle of described bung and the sealing of described staving, in described staving, be provided with special fine sand, the special fine sand described in when core is placed in described staving is filled between described staving and described core.

Adopt the core vacuum save set of technique scheme, all combined by the conventional special fine sand in waste and old paint kettle, candle and building site, staving and lid are made up of waste and old paint kettle.Be applicable to the basic branch construction in work progress, the pile foundation of core sampling when constructing pile foundation, this kind of device made simple, easy to operate.Can adopt on-the-spot waste and old 3Kg paint kettle, candle, construction to be made with special fine sand, convenient in carrying, safety is firm, green material-saving, manufacture craft is simple etc.

Special fine sand must do drying and processing before use, ensure that as much as possible special fine sand water ratio reduces, in addition, core must be used the rebasing processing of special fine sand after drying before entering bucket, except above-mentioned condition, also need the candle piece liquid of thawing to fill up the groove of whole paint kettle and lid, can ensure to approach vacuum state in this device.

Adopt this device, there is convenient in carrying, safety firmly, green material-saving, the plurality of advantages such as manufacture craft is simple.

Brief description of the drawings

Fig. 1 is the utility model apparatus structure schematic diagram.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility unit is described further.

Referring to Fig. 1, the candle 3 that staving 1 is provided with bung 2 and bung 2 and staving 1 are sealed, is provided with special fine sand 4 in staving 1, core 5 be placed on staving 1 when interior special fine sand 4 be filled between staving 1 and core 5.

Referring to Fig. 1, the special fine sand 4 that it is staving 1 and lid 2, candle 3 that this device adopts 3Kg paint kettle (be of a size of 16cm (diameter) X20cm (highly), just meet core size), dry, material is simple, be easy to prepare, and can recycle waste product.Adopt following steps:

1, special fine sand 4 is dried: sample front ten minutes at core 5, special fine sand for building is started to dry, the water ratio of sand is significantly reduced;

2, candle piece melts: the candle 3 that in 5 first three minutes of sampling of core, appropriate candle piece is melted into liquid;

3, dry special fine sand 4 rebasing: pouring the special fine sand 4 of drying into paint kettle is in staving 1, allows special fine sand 4 be covered with the bottom 1cm that paint kettle is staving 1;

4, core 5 enters bucket: it is staving 1 that the standard size core 5 of taking-up is vertically put into paint kettle;

5, dry special fine sand joint filling: pouring the special fine sand 4 of drying into paint kettle is in staving 1, the full paint kettle of filling is the gap between staving 1 and core 5, and is filled up to the top that paint kettle is staving 1, covers bung 2;

6, candle piece liquid sealing: by the candle piece liquid of thawing be candle 3 to be poured over paint kettle be in the groove between staving 1 and bung 2, till filling up, guarantee air does not enter staving 1.

Claims

1. a core vacuum save set, it is characterized in that: the candle (3) that staving (1) is provided with bung (2) and described bung (2) and described staving (1) are sealed, in described staving (1), be provided with special fine sand (4), core (5) is placed between the staving (1) of the special fine sand (4) of described staving (1) described in when interior described in being filled in and described core (5).
