Abstract

The utility model discloses a pile foundation mud pit which resolves the problems that the traditional mud pit is easy to collapse and a lot of mud is consumed away in the construction process of civil engineering pile foundation. The pile foundation mud pit comprises a mud pit body (1), a pile foundation pile casing (4) and a mud pump (6). The mud pit body (1) is a steel pile casing. A concave opening (2) is arranged at the top end of the mud pit body. A mud discharging groove (3) is arranged between the concave opening (2) of the mud pit body and the pipe foundation pile casing (4). A filtering sliding groove (8) is arranged above the mud pit body. An inlet of a suction pipe (5) of the mud pump (6) is arranged in the pile foundation pile casing (4). An outlet of an output pipe (7) of the mud pump (6) is arranged above the top end of the filtering sliding groove (8). The pile foundation mud pit has the advantages of being small in occupied space, material-saving, low in protection cost and not easy to collapse.

Description

A kind of pile foundation mud pit
Technical field
The utility model relates to the mud pit that uses in a kind of civil engineering.
Background technology
In pile foundation construction, the application of mud and processing are very important links, and it directly influences construction quality, progress, and the safety of pile foundation.When pile foundation is arranged in river, fill out the river if adopt the job practices of traditional mud pit need have bad luck a large amount of rock ballasts, smooth place, and also traditional mud pit wall hole is a lot, and a large amount of mud can be consumed, and the mud pit wall also is easy to cave in, and general effect is very poor.
Summary of the invention
The utility model provides a kind of pile foundation mud pit to solve in civil engineering pile foundation construction process, traditional mud pit wall technical problem that a large amount of mud can be consumed of caving in easily.
The utility model overcomes the above problems by following scheme:
A kind of pile foundation mud pit, comprise mud pit, pile foundation casing and slush pump, described mud pit is a steel casing, top at the mud pit of steel casing is provided with a recess, between the recess of mud pit and pile foundation casing, be provided with and let out stock tank, be provided with the filtration chute on the mud pit of steel casing, the inlet of the suction pipe of slush pump is arranged in the pile foundation casing, and the outlet of the efferent duct of slush pump is arranged on the top, top of filtering chute.
Around the steel casing of mud pit, be provided with the clay sealant.
The utlity model has take up an area of little, material saving, the protection expense is low and the advantage that is difficult for caving in.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Specific embodiment
A kind of pile foundation mud pit, comprise mud pit 1, pile foundation casing 4 and slush pump 6, described mud pit 1 is a steel casing, top at the mud pit of steel casing is provided with a recess 2, between the recess 2 of mud pit and pile foundation casing 4, be provided with and let out stock tank 3, be provided with on the mud pit of steel casing and filter chute 8, the inlet of the suction pipe 5 of slush pump 6 is arranged in the pile foundation casing 4, and the outlet of the efferent duct 7 of slush pump 6 is arranged on the top, top of filtering chute 8.Around the steel casing of mud pit 1, be provided with the clay sealant.
Concrete constructure scheme is: in construction, remove in water and fill out stake position and the pioneer road, fill a small amount of place again and be used for embedding steel casing, as mud pit, seal with clay on every side at the bottom of the steel casing.The groove mouth of mud pit casing is higher than the casing of pile foundation, and making sluicing groove is connected to the pile foundation casing.Use during clear hole in the iron filtration chute that a slush pump is provided with the top of the mud suction mud pit in the hole, mud is filtered, rock ballast can be filtered out and be slipped to outside the mud pit along filtering chute, mud is then filtered mud unnecessary in the mud pit and can be got back in the boring along the sluicing concentrated flow by the groove mouth of mud pit, realizes the separation of rock ballast, mud.According to the contrast of practice of construction, new mud pit saves human and material resources than traditional mud pit and clear hole efficient is higher.
The utility model takes up an area of at 8m according to this bridge pier base situation tradition mud pit 2More than; It only is the occupation of land of a steel casing that new mud pit takes up an area of.Conventional method need be had bad luck a large amount of rock ballasts and be filled out the river guaranteeing the construction of mud pit, mud pit is big more then need more; The utility model only needs to fill the job platform of a steel casing.Conventional method needs the wall of a large amount of clay shutoff mud pits, and the later stage also will constantly be added clay to replenish the mud that runs off, and the wall mud in the pond finally must be cleared up mud pit because dehydration sticks together with rock ballast and be sticking more many more; Can get rid of mud in the mud pit when rock ballast that the utility model is released jolts, and the mud pit wall is steel that mud can not run off on slideway.Conventional method needs often the rock ballast in the mud pit to be cleared up, otherwise can't guarantee the circulation of mud; The utility model rock ballast separates automatically with mud, does not have rock ballast in the mud pit, need not clear up.Conventional method be water pump is extended the hole at the bottom of, rock ballast is suspended in the mud slowly overflows; Rock ballast is suspended at the bottom of the hole more during the clear hole of the utility model, and slush pump can be directly with its extraction.Mud pit is bigger in the conventional method, and protection expense nature is bigger than new method, and mud pit is higher than general ground in the utility model, and area is very little, and the protection expense seldom.The mud pit wall is washed away by water and is easy to cave in the conventional method; So mud pit in the utility model is owing to adopt the steel casing can not cave in.
Also can adopt the mud pit of this form in the pile foundation construction of land.Especially for the construction plant deficiency, geology mostly is gravel, erratic boulder, the area of features such as lithic drainage prosperity.The tradition mud pit is the difficult point of civilized construction, and fills out processing for guaranteeing to set a roof beam in place also need change mud pit in the future.Mud pit of the present utility model is removed outside the advantage that above water king-pile mentions, and the most important thing is that post-processed is very simple, only need change to fill out to the hole of its steel casing size, and the material-saving that saves time, and because it is small, regular.
