Abstract
The utility model discloses a grout injector metal casting, which is characterized by comprising a black iron tube, a one-way valve installed at one end of the black iron tube and capable of preventing grout from flowing inwards, and a seal head installed at the other end of the black iron tube. A plurality of grout outlets are evenly arranged on the cylindrical face of the black iron tube; and a grout outlet protection cover layer is wrapped on the outer sides of the grout outlets. The group injector metal casting with simple structure has certain rigidity, when a steel reinforcement case is placed down, a shock electric hammer is used for pressing a grout injection tube into a pile bottom sediment and soft earth portion, and a grout injection protection device is arranged on the grout injector metal casing to ensure smoothness of a grout injection pipeline. The grout injector metal casting has reliable sealing performance and one-way valve performance necessary to after grouting, can effective stop sludge from entering the grout injection tube in placing, burying and underwater concrete injecting processes of grout injecting materials, and can form a grout injecting passage in grout injecting, ensures grout can just flow outwards but cannot flow inwards, achieves one-time grout injection success rate up to 99%, and increases grout injection effect.
Description
Technical field
The utility model relates to a kind of metal casting part, relates to a kind of efficient slurry casting machine of slip casting when being used for building operations specifically.
Background technology
At present, in the drilled pile construction, great majority adopt post grouting process to increase bearing area, increase reverse prestressing force, the bearing capacity of raising bored 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.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of slurry casting machine metalwork, and good airproof performance can not have clogging, improves slip casting effect.
The utility model is achieved through the following technical solutions:
A kind of slurry casting machine metal casting; it is characterized in that: comprise black pipe, be installed in the one way valve that black pipe one end can prevent stream in the slurries; and the end socket that is installed in the black pipe other end; on the face of cylinder of black pipe, evenly be provided with a plurality of slurry outlets, coat one deck slurry outlet protective cover in the outside of slurry outlet.
Aforesaid a kind of slurry casting machine metal casting, it is characterized in that: black pipe is provided with several, and each black pipe head and the tail is tightly connected continuously.
Aforesaid a kind of slurry casting machine metal casting is characterized in that: closely connect in conjunction with sealing glue by screw thread between each black pipe, the black pipe outside seals with rubber sleeve.
Aforesaid a kind of slurry casting machine metal casting is characterized in that: the material of slurry casting machine metal casting is a steel pipe.
The beneficial effects of the utility model are:
The utility model slurry casting machine metal casting lower end adopts end socket to shut and can shield to slurry casting machine, even the slurry casting machine metal casting inserts soil, can not damage foundry goods yet, and can prevent that earth and powder on pit bottom blowout from going into Grouting Pipe, guarantee that the slurry casting machine metal casting is down to the safety of its lower end at the end, hole; 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.The termination of the utility model slurry casting machine metal casting is provided with one way valve simultaneously; simple in structure; certain rigidity is arranged; transfer when reinforcing cage and to adopt the vibrations electric hammer that Grouting Pipe is pressed into pile bottom sediment and loosened soil portion after finishing; the injected hole protective device is set on the slurry casting machine metal casting; guaranteed the unobstructed of grouting pipeline; during slip casting; carry out slip casting with high-pressure pump by slurry casting machine of the present utility model following soil body at the bottom of stake; slurries directly inject soil layer by the pile body grouting pipe through one way valve; thereby guarantee that slurries can only outflow to come in, the slip casting once success rate reaches 99%, has improved slip casting effect greatly.
