Description
Technical field
The present invention relates to plasma pouring constructing skill field, in particular to a kind of structure of voltage regulation that catchments for grouting construction.
Background technique
Consolidation grouting be in order to improve developmental joint fissure or have crushed zone rock physical and mechanical property and carry out
Grouting works.For karst as the natural phenomena formed under a kind of special geological conditions, it is each that karst can form scale in rock mass
Different weak structural face or cave, weakens the globality of rock foundation, and there are leakage problems, underground chamber is collapsed and gushed suddenly
Water gushes mud, roof fall problem, and the engineering problems such as foundation stability bring many hazards to engineering construction.
Development of resources, great infrastructure development project with the needs of socio-economic development, in above-mentioned karst area
It will be more and more.Water conservancy, traffic and urban operating mechanism project are mainly characterized by high to ground requirement for bearing capacity；Ground generallys use
Under the action of earth's surface and ground water pressure, it is mixed to be located at backfill since construction location is lower than earth's surface for the form of heavy excavation, deep basal pit
Often there is water burst at solidifying soil layer, these water bursts drive the cement slurry injected when grouting construction constantly to gush out, and lead to grouting quality
Decline can not even be in the milk.
Summary of the invention
The present invention provides a kind of structure of voltage regulation that catchments for grouting construction, opens greatly to solve to generally use in ground
It digs, under the form of deep basal pit, since construction location is lower than earth's surface, fill concrete is located under the action of earth's surface and ground water pressure
Often there is water burst at layer, these water bursts drive the cement slurry injected when grouting construction constantly to gush out, and grouting quality is caused to decline
The technical issues of can not being even in the milk.
To solve the above problems, the present invention adopts the following technical scheme that realization:
A kind of structure of voltage regulation that catchments for grouting construction is equipped with backfill coagulation including foundation pit and in the upper surface of foundation pit bottom
Soil layer, and the grout hole opened up in foundation pit bottom are opened up in the position that the upper surface seepage point of the foundation pit bottom is concentrated
There is catch pit；
Catchment covers are fixedly installed on the catch pit；
It is connected at the top of the catchment covers with balance pipe；
The filler that can be seeped water is provided in the catchment covers, the fill concrete layer is covered on the catchment covers.
It is interconnected, water burst can effectively be collected, when the water in catch pit using catch pit, catchment covers and balance pipe
When gradually increasing, enter catchment covers and balance pipe by filler gap, the water level in balance pipe gradually increase be finally reached with
The state of water burst hydraulic balance, after hydraulic balance, water burst, which will be reduced, even to disappear, to ensure that the smooth of grouting works
It carries out and can guarantee construction quality.
Preferably, the catchment covers are funnel-shaped structure, and big open end is downward.
Water burst is collected convenient for more large area using funnel structure and is introduced in balance pipe convenient for concentrating.
Preferably, the catchment covers are made using steel.
Catchment covers are made using steel, are able to bear biggish pressure, very helpful for the stabilization of structure.
Preferably, the balance pipe is steel pipe, and described steel pipe one end and the catchment covers top are welded.
Steel pipe is common engineered building materials, can be faster using welding manner using steel pipe convenient for construction and operation
Speed is more efficiently constructed.
Preferably, the diameter of steel tube is 150mm, thickness of pipe wall 6mm.
Preferably, the catch pit depth is less than 3m.
Catch pit depth is less than 3m, and this is the best practices value summed up in long-term engineering practice, and such depth can expire
The existing duty requirements of foot.
Preferably, the balance pipe upper end is provided with screw thread, is connected through a screw thread the length for being able to extend the balance pipe.
The length of balance pipe can be quicklyd increase using thread connecting mode, improve working efficiency.
Preferably, the filler includes sand, stone.
Sand, stone are the most common materials in building site, and they have certain load-bearing capacity and water permeable ability.
Preferably, the filler is constituted using geotextiles package gravel.
Preferably, the fill concrete layer uses C15 concrete.
Beneficial effect of the present invention includes:
Structure is simple, low in cost, easy to operate, and stability is good, convenient for assembling.
Detailed description of the invention
Fig. 1 is embodiment construction scene figure provided by the invention；
Fig. 2 is example structure schematic diagram provided by the invention.
In figure, each label is respectively indicated:
Foundation pit bottom 1, seepage point 11, catch pit 12, fill concrete layer 2, balance pipe 3, catchment covers 30, is filled out penetrating passage 10
Fill object 31, grout hole 4.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached in the embodiment of the present invention
Figure, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.The embodiment of the present invention being usually described and illustrated herein in the accompanying drawings
Detailed description is not intended to limit the range of claimed invention, but is merely representative of selected embodiment of the invention.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
As depicted in figs. 1 and 2, a kind of structure of voltage regulation that catchments for grouting construction, foundation pit bottom 1 in foundation pit it is upper
The position that surface seepage point 11 is concentrated offers catch pit 12, and the depth of general catch pit 12 is no more than 3 meters, and the diameter view in hole is existing
Depending on seepage point is how many, if seepage point mostly just excavate it is big some seepage point can be excavated a little bit smaller if lacking, do not do and have herein
Body limits.
It is placed with the filler 31 that water penetration can be allowed to cross gap using geotextiles package gravel in catch pit 12, needs to infuse
Meaning, as long as the filler 31 can seep water and have certain load-bearing capacity can be have to be not necessarily geotextiles
Wrap up the mode of gravel.Filler 31 is covered by catchment covers 30, and catchment covers 30 are the funnel-shaped structures made of steel, big
Opening is fixedly connected and is connected to balance pipe 3 by welding manner in small opening towards covered with filler 31.Balance pipe 3 is
Use diameter made of steel pipe for 150mm, thickness of pipe wall is the tubing of 6mm, is vertically established on foundation pit bottom 1, the upper end of pipe
Mode can be connected through a screw thread and realize extension.The upper surface of foundation pit bottom 1 and catchment covers 30 pass through the backfill of model C15
Concrete layer 2 wraps.
In use, as shown in Figure 1, underground water is along the water in the entrance catch pit 12 of penetrating passage 10, in catch pit 12
When gradually increasing, enter catchment covers 30 and balance pipe 3 by 31 gap of filler, the water level in balance pipe 3 gradually increases finally
Reach the state with water burst hydraulic balance, after hydraulic balance, water burst, which will be reduced, even to disappear, at this time can be toward grout hole
Cement slurry is poured into 4, because of hydraulic balance, therefore water flow will not be occurred without very big infiltration water flow and be asked what cement slurry was taken away
Topic, to ensure that going on smoothly and capable of guaranteeing construction quality for grouting works.
