The grouting sleeve valve tube structure comprises a plurality of drilled grouting holes in the foundation, the spacing of the drilled grouting holes is 1-1.5m, a casing material layer is arranged on a lateral wall with the drilled grouting holes, a grouting tube is arranged in the casing material layer and provided with grout outlets, a movable grouting device is arranged in the grouting tube, the lateral wall of the grouting device is provided with grouting holes, and grout-stopping rubber rings are arranged above and below the grouting holes of the grouting device. By means of the grouting sleeve valve tube structure, excessive mining and pollution on water resources in construction engineering are reduced, consumption of the underwater is reduced greatly, underwater resources are protected effectively, and green construction is achieved.
Description
Technical field
The utility model relates to building substrate reinforcing technique field, is specially a kind of building substrate at a distance from oozing the slip casting sleeve valve tubular structure that sealing intercepts water and handles.
Technical background
Along with carrying out fast of China's economic construction, builing industry is also flourish, and deep foundation ditch phreatic high building project is increasing.At present; When the engineering of construction deep-foundation pit engineering and phreatic high, still adopt the engineering of traditional curtain+light well point dewatering construction technology, on the one hand, construction speed is general relatively slowly; Difficulty of construction is big, extracts a large amount of underground water out and is discharged into the sewer pipe net and slatterns; On the other hand, whole precipitation process is bigger to the sedimentation of surrounding buildings thing, Influence of Displacement.Bring consumption and waste also constantly to strengthen simultaneously to resource.Data show that North China's groundwater resources over-extraction at present reaches 2000 billion cubic meters, formed a huge funnel underground.If in work progress, still adopt the well point precipitation that draws water, with causing bigger water resource waste, and since surface settlement can seriously influence other buildings of ground and get safety.
Summary of the invention
The utility model causes problems such as underground water waste and foundation settlement in order to solve existing extraction underground water method Ground Treatment in architecture construction, provides a kind of building substrate at a distance from oozing the slip casting sleeve valve tubular structure that sealing intercepts water and handles.
The utility model is realized that by following technical scheme a kind of building substrate comprises some inlet wells of being located in the ground at a distance from oozing the slip casting sleeve valve tubular structure that sealing intercepts water and handles; From 1-1.5m, the inlet well sidewall is provided with the sheath body bed of material, is provided with Grouting Pipe in the sheath body bed of material between inlet well; Grouting Pipe is provided with slurry outlet; Be provided with movable slurry casting machine in the Grouting Pipe, the slurry casting machine sidewall is provided with injected hole, and both sides are provided with and only starch rubber ring about the injected hole of slurry casting machine.
The use principle of the utility model is; Grouting pump is driven into the slip casting agent in the inlet well through slurry casting machine, and the slip casting agent is only starched the zone between the rubber ring through what injected hole entered into Grouting Pipe, then through the corresponding some pressure break of grout outlet with the sheath body bed of material; Be injected in the ground then; The slip casting agent is solidified the back and in ground, is formed netted stiffening frame, thereby plays consolidated subsoil, the effect of sealing precipitation.Wherein slurry casting machine can move up and down in Grouting Pipe, can carry out layer and section like this to the ground of different depth and reinforce.
Compared with prior art, the utility model mainly adopts depthkeeping, layering, segmentation and different pressures to carry out slip casting from lower to upper through Grouting Pipe to the soil body different lithology stratum in the ground, reaches the method for soil mass consolidation.Pass through two obstruction cushion rubbers up and down in the work progress; Slurries are limited in arbitrary segment limit in slip casting zone and pour into, reach the purpose of segmenting slip casting, disabler can move freely in sleeve valve pipe; In the slip casting zone, repeat slip casting as required; Reach strengthening soft foundation and resist underground artesian water effect, seal underground water route, form sealing with water-stop curtain on every side and intercept water, reach the purpose that precipitation not equally can normal construction.Reduce immoderate exploitation and the pollution of engineering construction, reduce phreatic consumption in a large number, effectively protected groundwater resources, realize green construction water resource.

Fig. 1 is the structural representation of the utility model
Among the figure: the 1-sheath body bed of material, the 2-Grouting Pipe, 3-slurry casting machine, 4-are only starched rubber ring, the 5-slurry outlet, the 6-injected hole, 7-fracture grouting district, 8-only starches rubber ring, the 9-ground.
The specific embodiment
Meaning as shown in Figure 1, a kind of building substrate comprises some inlet wells of being located in the ground 9 at a distance from oozing the slip casting sleeve valve tubular structure that sealing intercepts water and handles; From 1-1.5m, the inlet well sidewall is provided with the sheath body bed of material 1, is provided with Grouting Pipe 2 in the sheath body bed of material 1 between inlet well; Grouting Pipe 2 is provided with slurry outlet 5; Be provided with movable slurry casting machine 3 in the Grouting Pipe 2, slurry casting machine 3 sidewalls are provided with injected hole 6, are provided with and only starch rubber ring 4,8 in both sides about in the of 6 at the injected hole of slurry casting machine 3.
Described Grouting Pipe 2 is a screw-shaped plastic material pipe, is real pipe and floral tube two parts, the long 33cm of every joint, and diameter 48mm, the inlet well diameter is not less than 91mm.
The layout of inlet well point position: laying injected hole according to design drawing, is basic point with the central point, arranges according to blossom type; Injected hole is by spacing 1.0m, and marked, and pore-forming spuds in; Tremie pipe is installed then; And be pressed into sleeve shell material through this pipe and form the sheath body bed of material, mud is ejected outside the hole fully in the hole, extracts tremie pipe then; Grouting Pipe is installed at last, is lowered to slurry casting machine; Preparation slip casting agent, beginning slip casting; Should follow the principle of the two controls of grouting pressure and grouting amount during slip casting, order should be from the bottom to top, effluxes row in the back earlier; Separated row carries out at a distance from the hole, effluxes to be that quantitative filling, interior row are saturated slip casting; Begin to distinguish injection test before the formal slip casting, further to confirm parameters such as grouting pressure, grouting amount.Form fracture grouting zone 7 at last.
The control height of slip casting section; Adjacent two rounds; The lifting that should interlock guarantees that each interval can both have the slurries of relative saturation to infiltrate, simultaneously for guaranteeing under pressure; The diffusion radius of slurries with prevent that the excessive formation passage of slurries pressure runs off, grouting pressure should be strict controlled in the design parameter value.Confirm the grouting pressure of different soil according to the soil property situation in the reinforcing scope, grouting pressure requires to be controlled in 0.1～1.0Mpa scope.Sheath body bed of material cleavage fracture stress must not be greater than 1.0MPa.
