Description

Bored concrete pile for water conservancy construction with watertight fittings

Technical Field

The utility model relates to a bored concrete pile technical field specifically is a bored concrete pile for water conservancy construction with watertight fittings.

Background

The bored concrete pile is made up by directly making holes on the designed pile position, making its cross-section be circular, after the holes are formed, placing reinforcing cage in the holes and pouring concrete.

At present, in the water conservancy construction, the underground concrete drainage channel is accepted to the bored concrete pile more, the peripheral surrounding concrete layer of pouring the bored concrete pile, then drill out the corrugated surface at the bored concrete pile top, water drainage channel concrete bottom is poured on the bored concrete pile again, in order to prevent that bored concrete pile and the earth of surrounding concrete layer downside from soaking too much water and making the bored concrete pile support nature discount greatly, therefore it lays the waterproof layer to enclose at the bored concrete pile head side more, then lay the mortar layer on the waterproof layer, when pouring drainage channel concrete bottom, need chisel out the corrugated surface at the mortar layer upper surface, for take off and attach drainage channel concrete bottom, the weak point that exists has: because the waterproof layer has limited water resistance, the effect of preventing water from permeating from the joint gap between the cast-in-place pile and the side concrete layer is not good enough.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bored concrete pile for water conservancy construction with watertight fittings to it prevents the not good enough problem of effect of water from bored concrete pile and border concrete layer handing-over gap infiltration to provide in solving above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a bored concrete pile for water conservancy construction with watertight fittings, includes a jar stake body, pours at the limit of jar stake body border concrete layer and is located limit concrete layer upside and the concrete bottom of handing-over in bored concrete pile body top, be provided with the stagnant water layer between limit concrete layer and the concrete bottom, be provided with the waterproof layer between stagnant water layer and the concrete bottom, be provided with the mortar layer between waterproof layer and the concrete bottom, the border that is located the bored concrete pile body on the limit concrete layer presets prefabricated groove, the prefabricated inslot is built-in to be equipped with water shutoff ring and water shutoff ring cover and packs into the bored concrete pile body, be equipped with the inner chamber on the water shutoff ring, the built-in water absorption ring that is equipped with of inner chamber, water proof ring and water proof ring cover pack into the bored concrete pile body are installed to water shutoff ring's top.

Preferably, the water stop layer is at least two centimeters thick.

Preferably, the preformed groove is of a circular groove structure.

Preferably, the water plugging ring is a circular ring structure, the inner cavity is a circular groove structure, and the water absorbing ring is a circular ring structure.

Preferably, the water-proof ring is of a circular ring structure.

Compared with the prior art, the beneficial effects of the utility model are that:

first, when concrete bottom upside permeated through concrete bottom and oozed water downwards, because the stagnant water layer was the square sheet structure of 3 meters of individual side length, and the position of emboliaing the water proof ring was provided with square mouthful, and the inner wall of this square mouthful and the outer wall sliding fit of water proof ring, in the time of the actual operation, can tailor the stagnant water layer according to actual need, then the terminal surface laminating is laid, because stagnant water layer density is big, the effect of water proof has, can prevent most underwater seepage, the even coating of waterproof layer is on stagnant water layer upper surface, strengthen the water proof of stagnant water layer, plug up the gap between each square piece of stagnant water layer simultaneously, prevent that water from flowing downwards from the gap between each square piece of stagnant water layer.

Secondly, when in initial arrangement, the outer wall and the inner wall of the water plugging ring respectively and tightly extrude the inner wall of the inner cavity and the outer wall of the cast-in-place pile body, the water plugging ring has the water plugging effect, after the water absorption ring absorbs water, the water is not released, but expands after absorbing water, thereby the inner cavity is pressed outwards to cause the inner wall and the outer wall of the water plugging ring to expand outwards, the outer wall and the inner wall of the water plugging ring are extruded more tightly with the inner wall of the inner cavity and the outer wall of the cast-in-place pile body, the water sealing performance is better, the water-resisting ring is tightly sleeved on the outer wall of the cast-in-place pile body, not only can the water flow be prevented from permeating into the gap between the inner wall and the outer wall of the cast-in-place pile body from the gap between the water-resisting ring and the, the waterproof device has water-resisting property to the waterproof layer and the mortar layer, and can further stabilize the position of the water-stopping ring due to the tight attachment of the waterproof device on the outer wall of the cast-in-place pile body, so that the waterproof device is composed of the water-stopping layer, the water-stopping ring, the water-absorbing ring and the water-stopping ring.

In conclusion, groundwater that can more effectively prevent to ooze from concrete bottom upside infiltration from border concrete layer and bored concrete pile body outer wall handing-over gap infiltration.
