Abstract

The utility model relates to a hole wall back stopper. The utility model is composed of a sleeve pipe and back stopping sheets of the sleeve pipe, wherein, the upwards slantwise back stopping sheets of the sleeve pipe are circumferentially distributed and fixedly arranged on the outer wall of the sleeve pipe. Reinforcing ribs of the back stopping sheets of the sleeve pipe are arranged among the back stopping sheets of the sleeve pipe and the outer wall of the sleeve pipe. As the back stopping sheets of the sleeve pipe are upwards and slantwise expanded and arranged on the sleeve pipe, when the sleeve pipe is inserted in a hole and the sleeve pipe moves downwards, the expanded back stopping sheets of the sleeve pipe are inwards folded under the action of the hole wall, and thus the utility model smoothly and downwards moves in the hole. However, when the utility model upwards moves in the hole, the free ends of the back stopping sheets of the sleeve pipe are inserted into the hole wall and are outwards expanded, and then the utility model can not continuously and upwards move in the hole and the utility model is clamped in the hole. The filler which is arranged in the hole and is positioned in the sleeve pipe or under the sleeve pipe can not be upwards lifted and taken out, and the utility model has functions of theft prevention and float prevention.

Description

The hole wall backstopping device

Technical field: the utility model relates to a kind of exploration engineering utensil, is meant a kind of hole wall backstopping device especially.

Background technology: at present, exploration underground such as resource situations such as oil, rock gases the time, often adopt the artificial earthquake method to explore; The artificial earthquake method is exactly to beat a series of holes that keep at a certain distance away by the underground elder generation in the zone of needs exploration, in hole, load dynamite stick again, fired charge rod manufacture of intraocular earthquake simultaneously then, and a kind of comparatively advanced method of exploration of the situation of burying of the resources such as oil gas under coming definitely by Instrument measuring and analysis seismic event; The artificial earthquake method is owing to could ignite after need all installing dynamite stick in a series of holes of wide apart, therefore in the process that the filling personnel load, often the stolen incident of the dynamite stick that fills, thus unnecessary loss and social danger caused; In addition, when hole is beaten on the region in rich groundwater, usually be full of water in the hole, because water is to the buoyancy of dynamite stick, make dynamite stick can't fall into the bottom of hole, thereby cause floating big gun or chongtian mortar, have a strong impact on the accuracy of artificial earthquake method exploration.

The utility model content: the purpose of this utility model provides a kind of fill that is packed in the hole that can make and in a single day is loaded the hole wall backstopping device that just can not be removed again.

The purpose of this utility model is achieved in that a kind of hole wall backstopping device, and it is made up of sleeve and sleeve retaining sheet, and wherein acclivitous sleeve retaining sheet circumferentially scatters and is fixedly installed on the outer wall of sleeve.

Between the outer wall of sleeve retaining sheet and sleeve, be provided with sleeve retaining sheet reinforcement.

Because the sleeve retaining sheet on the utility model middle sleeve is inclined upwardly and opens setting, so when sleeve inserts in the hole and moves downward, open sleeve retaining sheet can be under the effect of hole wall inwardly draws in, thereby makes the utility model can be descending smoothly in hole; But, when the utility model moves upward in hole, the free end of the sleeve retaining sheet on the effect lower sleeve of upper lifting force or buoyancy can insert hole wall, and outwards open, thereby make the utility model be stuck among the hole continuing among the hole to move up, the utility model is being positioned among the utility model sleeve among the hole or fill below the sleeve also can't be moving upward and take out like this, so can play antitheft and anti-floating effect.

Fig. 2 is the vertical view of Fig. 1

Fig. 3 is the upward view of Fig. 1

Fig. 4 is that the A-A of Fig. 2 is to the sectional structure synoptic diagram

Embodiment: the utility model will be further described below in conjunction with accompanying drawing, a kind of hole wall backstopping device, and it is made up of sleeve 4 and sleeve retaining sheet 2, and wherein acclivitous sleeve retaining sheet 2 circumferentially scatters and is fixedly installed on the outer wall of sleeve 4; The purpose one that sleeve 4 is set is to be used for socket to be fixed on the fill, the 2nd, be used to guide the attitude of the utility model among hole, and prevent that the utility model from overturning among hole; Sleeve retaining sheet 2 can be to make with the material with certain elastic deformation, as metal, plastics etc.

In order to reduce materials amount of the present utility model, to reduce cost of the present utility model and weight, and guarantee that simultaneously stopping function of the present utility model does not die down, can also be provided with sleeve retaining sheet reinforcement 3 between the outer wall of sleeve retaining sheet 2 and sleeve 4, that so just sleeve retaining sheet 2 can be done is thinner.

According to sleeve 4 and by the connected mode needs of socket thing, sleeve 4 can be one side closed formula sleeve or through sleeve.

For make sleeve 4 exactly socket be positioned at by on the privileged site of socket thing, on the inwall of sleeve 4, can be provided with locating device; This locating device can be made up of the locating ring 5, positioning strip or the locating piece that protrude on sleeve 4 inwalls; The corresponding with it locating slot that is provided with indent by the relevant position on the socket thing; In general the sleeve in the utility model and by the socket thing as being to peg graft by the wringing fit mode to be fixed together between the TNT dynamite stick.

Grab the ability of closing for the free end that further improves sleeve retaining sheet 2 inserts in the hole wall or with hole wall, can also be provided with ratchet 1 in the free-ended end of sleeve retaining sheet 2.

For the inner chamber that makes the sleeve 4 in the utility model can successfully be socketed on the different bar-shaped fill of shape of cross section, the shape of cross section of sleeve 4 inner chambers can be circle, ellipse, rectangle, trapezoidal, polygon or complex.

The using method of the utility model in the artificial earthquake method is as follows: if the shape of cross section and the size of the shape of cross section of dynamite stick and size and sleeve 4 inner chambers cooperatively interact, then the utility model is socketed in the rear end of dynamite stick, will be equipped with then and both can at the bottom of dynamite stick of the present utility model is put into hole and dynamite stick is pressed into the hole of hole with insulating bar;

If the shape of cross section of dynamite stick and size do not match with the shape of cross section and the size of sleeve 4 inner chambers, again the utility model is put among the hole after then earlier dynamite stick being put into hole, both can at the bottom of dynamite stick and the utility model together being pressed into the hole of hole with insulating bar at last.

Will note selecting for use according to the diameter of hole the utility model of different sizes during use, in general the diameter of hole should be greater than the diameter of the utility model middle sleeve 4, and the diameter that surrounds less than sleeve retaining sheet 2.

Certainly the utility model also can be used among other occasion with similar functions requirement.
