Abstract
The invention discloses the spray of a kind of felted high pressure swing and combine with soldier pile the curtain that blocks water, it is provided with soldier pile around architectural engineering pit, the cementing reinforcing of the capable soil body of high pressure swing spirt is adopted between soldier pile, and make to be formed between the cementing soil body after reinforcing and soldier pile to be connected, wherein the vertical distance of high pressure spray orifice and soldier pile is 1/4 of soldier pile diameter, distance between high pressure spray orifice and high pressure spray orifice is not more than the diameter of soldier pile, and pendulum spray angle degree is 30 ~ 45 degree.The present invention utilizes high pressure swing spray to carry out cementing reinforcing to the soil body between soldier pile, and the as a whole common formation that is connected of the cementing soil body and soldier pile is blocked water curtain, decrease the support engineering amount of inter-pile soil, reduce the adverse effect of a large amount of precipitation to environment, guarantee engineering safety.
Description
Technical field
The present invention relates to a kind of building engineering construction field curtain that blocks water, is that the spray of a kind of felted high pressure swing combines with soldier pile the curtain that blocks water specifically.
Background technology
Often need to block water process to foundation ditch in building engineering construction, the curtain structure that blocks water the most often used at present mainly pre-sets soldier pile in foundation ditch surrounding, net spray mask is provided with between soldier pile, collapse to prevent the collapse body around foundation ditch, and (outside foundation ditch) is provided with a row or multi-row curtain and the high-pressure rotary jet grouting pile formation of occlusion mutually blocks water continuously again on rear side of soldier pile, this curtain that blocks water adopts high-pressure rotary-spray cement paste that native rock mass is carried out cementing reinforcing, distance wherein between churning point and soldier pile center is 1 ~ 1.5 times of soldier pile diameter, distance between churning point and churning point is no more than rotary churning pile diameter, more completely body is engaged to guarantee that each churning point is formed.The curtain that blocks water that this high-pressure rotary-spray is formed serves good interception to the infiltration of soil layer moisture content around foundation ditch, but because of rotary churning pile quantity more, comparatively large to the consumption of cement paste, and need again to arrange more churning point, cause construction period longer.And distant between curtain and soldier pile owing to blocking water, also because soldier pile and the soil body lack stronger protection, needing, steel mesh reinforcement is set and carries out consolidation process, add engineering quantity and engineering cost.
Summary of the invention
In order to solve existing support system and the deficiency of the curtain that blocks water, the invention provides the spray of a kind of felted high pressure swing and combine with soldier pile the curtain that blocks water, not only can play stronger resistance effect to foundation ditch, and a large amount of cement pastes can be saved, decrease engineering quantity.
The present invention is realized by following technical proposals: it is provided with soldier pile around architectural engineering pit, the cementing reinforcing of the capable soil body of high pressure swing spirt is adopted between soldier pile, and make to be formed between the cementing soil body after reinforcing and soldier pile to be connected, vertical distance between the plane be made up of the axis of high pressure spray orifice and the plane be made up of the axis of soldier pile is 1/4 of soldier pile diameter, distance between high pressure spray orifice and high pressure spray orifice is not more than the diameter of rotary churning pile, and the pendulum spray angle degree carried out when putting spray operation is 30 ~ 45 degree.The cementing soil body is connected as a whole common formation to block water curtain with soldier pile, not only there is the effect preventing the avalanche of soldier pile inter-pile soil, but also effect soldier pile being provided with block water, eliminate the use of steel mesh reinforcement simultaneously.Adopt the high pressure swing spray angle degree of 30 ~ 45 degree to make the cementing soil body become quadrilateral structure, and utilize the setting of the diagonal angle of this quadrangle to be used as the curtain that blocks water, further save cement paste consumption, decrease the engineering quantity of the curtain construction that blocks water, reduce engineering cost.
The invention has the beneficial effects as follows: not only can play stronger resistance effect to foundation ditch, and the cementing soil body reinforced through high pressure swing spray is connected as a whole with soldier pile, the curtain that blocks water that common formation one is complete, a large amount of cement paste consumptions can be saved, reduce engineering construction amount, reduce engineering cost, easy construction, Be very effective, is convenient to promote the use of.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is the cross-sectional view of the curtain that blocks water that construction is conventional at present.
Fig. 2 is cross-sectional view of the present invention.
Code description in figure: 1-soldier pile; 2 '-element spray mask; 2-net spray mask; 3-high pressure spray orifice; The cementing soil body of 4-; 5-collapse body; A, a '-high pressure spray orifice is to the distance of soldier pile; B, b '-high pressure spray pitch of holes.
Detailed description of the invention
As shown in Figure 1, the resistance curtain that construction is conventional is at present formed primarily of soldier pile 1 with through the cementing soil body 4 that high pressure spray orifice 3 is formed, and because adopting high-pressure rotary-spray, thus its cementing soil body formed is cylinder, and the cement paste of consumption is also more.Simultaneously because the distance between the cementing soil body and soldier pile is excessive, the net spray mask 2 reinforced through steel mesh reinforcement also need be adopted to the supporting of collapse body 5, to reinforce collapse body.
As shown in Figure 2, the present invention adopts the cementing reinforcing of the capable soil body of high pressure swing spirt between soldier pile 1, wherein high pressure spray orifice 3 is 1/4 of soldier pile diameter with the vertical distance a of soldier pile 1, namely the vertical distance a between the plane be made up of the axis of high pressure spray orifice 3 and the plane be made up of the axis of soldier pile 1 is 1/4 of a stanchion diameter, the pendulum spray angle degree carried out when putting spray operation is 30 ~ 45 degree, to reduce unnecessary cement paste waste, simultaneously for improving the cementing effect of the soil body, distance b between high pressure spray orifice and high pressure spray orifice is not more than the diameter of rotary churning pile, be connected to make to be formed between the cementing soil body 4 after reinforcing and soldier pile 1.The cementing soil body is connected with soldier pile as a whole and jointly forms the curtain that blocks water by the present invention, not only has the effect preventing from making the avalanche of soldier pile inter-pile soil, but also effect soldier pile being provided with block water.The use also making the collapse body 5 between supporting eliminate steel mesh reinforcement that is connected of the cementing soil body and soldier pile, only can carry out effective support with element spray mask 2 '.The high pressure swing angle of 30 ~ 45 degree is adopted to make the cementing soil body become a quadrilateral structure, because pendulum spray angle degree is no more than 45 degree, thus can ensure that the distance between 2 high pressure spray orifices in this quadrilateral structure is ultimate range, even if this cementing soil body occupies larger area between soldier pile, further reduce cement paste consumption, decrease the engineering quantity of the curtain construction that blocks water, shorten the duration, reduce engineering cost.
