Abstract
The utility model discloses a construction device of a sand stratum precipitation well. The construction device comprises a well pipe, a high-pressure water pump and a high-pressure water pipe, wherein a water inlet pipe of the high-pressure water pump is communicated with the high-pressure water pipe; the high-pressure water pipe penetrates an inner cavity of the well pipe; and a reversed filter layer capable of supplying water and preventing sand grains from entering the inner cavity of the well pipe is arranged on the outer wall surface of the well pipe. By adopting the technical scheme, the well pipe easily sinks into the precipitation well and does not bear resistance of an underground sand layer, and the precipitation well does not easily collapse after being dug well. The bottom of the well is rinsed by high-pressure water, so that the inside of the wall is relatively clean.
Description
Technical field
The utility model relates to a kind of apparatus for building, particularly a kind of construction equipment of sandy strata precipitation well.
Background technology
At present, adopt mud off in the sandy strata, and carry out punch operation with the mode of machine drilling.Because the sandy strata soil property is pine, the hole that in the process of boring, collapses easily puts in place under well casing is difficult to, and the mud skin that adheres on the hole wall simultaneously is blocked up, influences the effect of precipitation well.
The utility model content
Be to solve the technical problem that exists in the prior art, the utility model provides a kind of and can construct to sandy strata precipitation well quickly and easily, and the construction equipment of the stable sandy strata precipitation well of the precipitation well that forms.
The utility model solves the problems of the technologies described above, and the technical scheme that is adopted is: a kind of construction equipment of sandy strata precipitation well is provided, comprises a well casing, a high-pressure hydraulic pump and a high-pressure water pipe; The water inlet pipe of said high-pressure hydraulic pump is communicated with said high-pressure water pipe, and said high-pressure water pipe runs through the inner chamber of said well casing, intercepts the loaded filter that sand grains gets into said well casing inner chamber but the outside wall surface of said well casing is provided with water flowing.
As the preferred version of the utility model, the degree of depth of said precipitation well is 10m-15m.
The technical scheme of the utility model is with respect to prior art; The beneficial effect of obtaining is: the construction equipment of the described sandy strata precipitation of the utility model well; Water under high pressure is drawn in the high-pressure water pipe through high-pressure hydraulic pump, on one side water under high pressure over the ground the layer of sand at the end wash, Yi Bian with the inlet pipe pressed downward; Then gone out by the sand grains of water under high pressure punching press through well casing inner chamber, high-pressure water pipe exocoel.According to the pressure size of drawing water of high-pressure hydraulic pump, can realize the punching of the degree of depth at the bottom of the ground of 10m-15m.Therefore, it is easy that well casing rises up into the precipitation well, can not receive the resistance of ground bed load layer, and after the precipitation well accomplishes fluently, also be not easy to cave in.The shaft bottom is owing to receiving washing away of water under high pressure, and is comparatively clean in the well.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the part of the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the construction equipment of the described sandy strata precipitation of the utility model well.
The specific embodiment
In order to make the utility model technical problem to be solved, technical scheme and beneficial effect is clearer, understand,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the utility model provides a kind of construction equipment of sandy strata precipitation well, comprises well casing 10, high-pressure hydraulic pump 20 and high-pressure water pipe 30; The water inlet pipe 22 of high-pressure hydraulic pump 20 is communicated with high-pressure water pipe 30, and high-pressure water pipe 30 runs through the inner chamber of well casing 10, intercepts the loaded filter 12 that sand grains gets into said well casing 10 inner chambers but the outside wall surface of well casing 10 is provided with water flowing.Therefore, after the precipitation well is got through, in well casing 10, be placed with a suction pump (not shown); Underground water in the precipitation well periphery layer of sand is through the inner chamber of the loaded filter 12 entering well casings 10 of well casing 10, and sand grains is intercepted by loaded filter 12, and underground water is extracted out by suction pump.It is easy that well casing 10 rises up into the precipitation well, can not receive the resistance of ground bed load layer, and after the precipitation well accomplishes fluently, also be not easy to cave in, the shaft bottom is owing to receive washing away of water under high pressure, and is comparatively clean in the well.The degree of depth of precipitation well can be 10m-15m.
Above-mentioned explanation has illustrated and has described the preferred embodiment of the utility model; As previously mentioned; Be to be understood that the utility model is not limited to the form that this paper discloses, should do not regard eliminating as, and can be used for various other combinations, modification and environment other embodiment; And can in utility model contemplated scope described herein, change through the technology or the knowledge of above-mentioned instruction or association area.And change that those skilled in the art carried out and variation do not break away from the spirit and the scope of the utility model, then all should be in the protection domain of the utility model accompanying claims.
