Abstract
The utility model provides a bored pile post-pressure-grouting grouting device used for the soft ground. A long cylinder column body is arranged in a pile bottom-soil body. A grouting inlet is connected with a grouting pipe which is arranged in the steel-reinforcement cage of the drilling pile. A grouting device body is composed of five black iron pipes, and each black iron pipe is orderly connected by a white iron casing. The cylindrical surface of each black iron pipe is provided with one group of small holes which are in the quincunx arrangement. The outside of the black iron pipes are sealed with the rubber sleeves. The bottom of the grouting device body is provided with a white iron sealing head. The utility model has the reliable sealability required of the later pressure grouting, and the one-way valve performance. The slurry is effectively prevented from entering the grouting pipe in the process of the placing and the embedding of the grouting material and the perfusion process of the underwater concrete. The utility model can be opened under the lower pressure in grouting to form a grouting channel, and has the definite ability of resisting the external damage.
Description
Technical field
The utility model relates to a kind of construction implement, especially a kind of slurry casting machine of the post-pressure grouting that is used to hole.
Background technology
At present, in the drilled pile construction, great majority adopt post grouting process to improve bearing capacity of pile, reduce the pile body settling amount, thereby can reduce a number, reduce cost and reduction of erection time.And drilled pile post grouting process key of success is a slurry casting machine.
The slurry casting machine that existing grouting behind shaft or drift lining is used is to make according to the actual conditions of each engineering, the simple and easy grouting valve of general employing, sealing is poor, in practice of construction, variety of issue can appear in slurry casting machine, especially severe be that earth and powder on pit bottom sand pour in Grouting Pipe easily, cause slurry casting machine to lose efficacy, thereby make the slurry casting machine cisco unity malfunction, success rate is extremely low, has prolonged construction period to a certain extent and has increased construction costs.
Summary of the invention
The utility model purpose is exactly to solve the problem that slurry casting machine exists in the construction of drilled pile grouting behind shaft or drift lining, provide a kind of the laying of injecting paste material, bury underground, can effectively stop mud to enter Grouting Pipe in the underwater concrete pouring process, and when slip casting, under lower pressure, can open again, form the slip casting passage, and possess the slurry casting machine of the outer damage capability of certain opposing.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of soft clay area boring post-pressure grouting slurry casting machine, oval barrel mast body places in the subsoil body, the slip casting input port joins with placing the Grouting Pipe in the drilled pile reinforcing cage, the slurry casting machine body is made up of five sections black pipes, connect successively with the galvanized iron overcoat between each section black pipe, have one group of aperture that is quincuncial arrangement on every section black pipe face of cylinder, the outside seals with rubber sleeve, and slurry casting machine body bottom envelope has the galvanized iron end socket.
Slurry casting machine length is 50cm, and inner hole section is long-pending to be 572mm
2, the slurry outlet gross area is 961mm
2, and be placed in and stretch out 40-50cm position at the bottom of the reinforcing cage.
One group of aperture that is quincuncial arrangement being opened on every section black pipe face of cylinder is five holes that diameter is 7mm.
The utlity model has the positiver sealing and the one way valve performance of back mud jacking indispensability, the slurry casting machine end opening adopts the galvanized iron end socket to shut and can shield to slurry casting machine, even slurry casting machine inserts soil, can not damage slurry casting machine yet, and can prevent that earth and powder on pit bottom blowout from going into Grouting Pipe, guarantee that slurry casting machine is down to the safety of hole end opening at the end; Adopt rubber sleeve that injected hole is sealed, do the time spent at certain defeated slurry pressure, rubber sleeve can be washed open, make slurries pass through injected hole and slowly inject the soil body, and the injected hole area is long-pending greater than the slurry casting machine inner hole section, can satisfy the construction process requirement of boring post-pressure grouting fully.In addition, slurry casting machine is placed in stretches out 50cm place at the bottom of the reinforcing bar bone cage, can avoid concrete that slurry casting machine is encased the grouting behind shaft or drift lining hole by the situation that blocks and can't rive, and guaranteeing under the long situation of stake, formed a loose slip casting district isolated, thereby can guarantee the successful implementation of back mud jacking construction technology with pile body.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the utility model is laid embedding schematic diagram.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1; soft clay area boring post-pressure grouting slurry casting machine; black pipe 1 by five sections Φ 33.5mm * 3.25mm is formed; use 2 fixed seal connections of galvanized iron overcoat between each black pipe 1 vertically; its bottom one section end opening is shut with galvanized iron end socket 5; can shield to slurry casting machine; even slurry casting machine inserts soil; can not damage yet, and can prevent that earth and powder on pit bottom blowout from going into Grouting Pipe, guarantee that slurry casting machine is down to the safety of hole end opening at the end slurry casting machine; the hole 4 that to have five diameters on every section black pipe 1 face of cylinder be 7mm; and being quincuncial arrangement, certain external force effect can be resisted with rubber sleeve 3 sealings in the outside; after embedding finishing; with certain defeated slurry pressure, rubber sleeve 3 is washed open, make slurries pass through injected hole 4 and slowly inject the soil body.
Slurry casting machine length after the connection is 50cm, and inner hole section is long-pending to be 572mm
2, the slurry outlet gross area is 961mm
2, the injected hole area is long-pending greater than the slurry casting machine inner hole section, can satisfy the construction process requirement of boring post-pressure grouting fully.
As shown in Figure 2,, slurry casting machine is stretched out 7 end of reinforcing cage 50cm laying when descending most joint reinforcing cage 7, slurry casting machine can be inserted cheat in the subsoil body 8, do not encased by concrete to guarantee slurry casting machine according to dark, the shallow characteristics in next door in the middle of behind the drilled pile pore-forming.Avoid concrete that slurry casting machine is encased the situation appearance that the grouting behind shaft or drift lining hole is blocked and can't rive fully, and guaranteeing to form a loose slip casting district isolated under the long situation of stake with pile body.
The slurry casting machine input port joins with placing the Grouting Pipe 6 usefulness galvanized iron overcoats 2 in the drilled pile reinforcing cage 7.Grouting Pipe 6 and reinforcing cage 7 main muscle firm fixation, and with reinforcing cage 7 integral body transfer (to reinforcing cage 7 not on earth the stake, then must increase the guiding reinforcing bar hangs together, to guarantee the stability and the verticality of Grouting Pipe 6), adopt the silk tooth to connect between the tube and tube, wrap up with the sealing adhesive tape at screw thread place, outside, and firmly tighten sealing, when every joint reinforcing cage 7 is transferred end, must in Grouting Pipe 6, inject clear water and check the sealing performance of pipeline, water filling in Grouting Pipe 6 can also reduce negative pressure in the Grouting Pipe 6, to prevent owing to the Grouting Pipe 6 external and internal pressures caulking gum 3 that makes slurry casting machine that differs greatly is damaged by pressure.When slurry casting machine during the end, adopts the little stroke of hoist engine to insert soil body 50cm near stake.
