Abstract
The utility model relates to a drilling and spraying integrated device, and belongs to the technical field of high-pressure grouting construction equipment. The drilling and spraying integrated device comprises a device body, wherein a conical hole is formed in the lower part in the device body, a water port is arranged on the conical hole, a cone with a guide rod is arranged above the conical hole, and a spray port is formed in the upper part of the device body. The drilling and spraying integrated device disclosed by the utility model adopts the process of firstly drilling and then spraying grout, a grouting pipe does not need to be mounted additionally during the whole process, the process steps are reduced, the operation becomes simpler and more convenient, the influence of hole collapse on construction is avoided, and the working efficiency is improved.
Description
Technical field
The utility model relates to brill spray integrated device, belongs to high-pressure slip-casting construction equipment technical field.
Background technology
At present, in engineering construction, can increase formation strength and impermeability by high-pressure slip-casting, improve supporting capacity and the impervious ability of foundation soil, guarantee the safe operation of engineering services.Existing high-pressure slip-casting method commonly used is as follows: become guide hole with rig earlier, propose drilling tool, Grouting Pipe is installed in guide hole again carries out the high-pressure slip-casting construction.The shortcoming of this method is: one, need pore-forming in advance, propose drilling tool, Grouting Pipe is installed again, operation is many, complicated operation, inefficiency; Two, the hole of easily collapsing behind the pore-forming, Grouting Pipe can not be inserted into projected depth, influences efficiency of construction and quality.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and provides that a kind of operation is few, easy and simple to handle, efficient is high, is not subjected to formation influence, does not need repeatedly the brill spray integrated device of pore-forming.
The utility model is achieved through the following technical solutions:
Bore the spray integrated device, its special character is to comprise device body 1, and the below, inside of device body 1 is provided with circular cone cave 2, and circular cone cave 2 is provided with the mouth of a river 4, and 2 tops, circular cone cave are provided with the cone 3 of guide peg 6, and the top of device body 1 has spout 5;
The quantity of described spout 5 is one or two.
Brill spray integrated device of the present utility model adopts and creeps into the operation of afterwards whitewashing earlier, and whole process does not need Grouting Pipe is installed in addition, has reduced operation, makes that operation is easier, and operating efficiency has been improved to the influence that construction causes in the hole of having avoided simultaneously collapsing.

Among the figure: 1, device body, 2, the circular cone cave, 3, cone, 4, the mouth of a river, 5, spout, 6, guide peg.
The specific embodiment
Provide the specific embodiment of the present utility model below with reference to accompanying drawing, be used for formation of the present utility model is described in further detail.
The brill spray integrated device of present embodiment comprises device body 1, and the below, inside of device body 1 is provided with circular cone cave 2, and circular cone cave 2 is provided with the mouth of a river 4, and 2 tops, circular cone cave are provided with the cone 3 of guide peg 6, and the top of device body 1 has spout 5; The quantity of spout 5 is two.
Operating procedure is as follows: during the rig drilling and forming hole, and device body 1 top jointed rod, the below connects comprehensive drill bit, and do not put cone 3 in the device body 1 this moment, and circulating mud liquid is the comprehensive drill bit of 4 inflows from the mouth of a river, normally creeps into; During the high-pressure slip-casting construction, put into cone 3 in device, cone 3 falls into circular cone cave 2, has sealed the cement paste passage of circulation downwards: the mouth of a river 4, then cement paste is finished the high pressure jet grouting construction from 5 ejections of two spouts.
The beneficial effect of present embodiment is as follows:
Do not place cone when 1, normally creeping in the device, because mouth of a river diameter is much larger than nozzle diameter, so circulating mud liquid flows out from the mouth of a river, play the effect of residue and retaining wall at the bottom of cooling drill bit, the cleaning eye;
When 2, waiting to be drilled into the high-pressure slip-casting design elevation, use clear water instead (adopt this procedure cleaning residual mud make slip casting effect better) cleaned in drilling tool, integrated device and boring;
3, after cleaning finishes, turn on drilling tool, cone is put into device body, when cone drops down onto place, circular cone cave, sealed the downward passage of slurries;
4, during mortar depositing construction, cement paste flow to the cone position along drilling tool, because cone is downward channel seal, then cement paste sprays from spout, according to design parameters, progressively changes injection direction and promotes drilling tool, finishes the high-pressure slip-casting construction.
The unspecified content of the utility model is prior art, and those skilled in the art can obtain to inspire from present embodiment and prior art, is out of shape to obtain other embodiment.Therefore, protection domain of the present utility model should be determined according to the protection domain of claim.
