The purpose of example.For sake of convenience, "upper" described below, "lower" are consistent with the upper and lower direction of attached drawing, but this can't be
The limitation of technical solution of the present invention.
Embodiment one
Below with reference to Fig. 1 to Fig. 4, the structure composition for the removable mud pit that the present invention will be described in detail.
A kind of removable mud pit, it includes: car body 10 and cabinet 20, and cabinet 20 is installed on car body 10 by mounting rack 30
Top, mounting rack 30 are connected with rotary electric machine 40 at car body head position, and 20 head end of cabinet is connect with rotary electric machine 40, case
Body 20 can carry out axial rotation under the action of rotary electric machine 40；Cabinet 20 is the cabinet top being mutually communicated and lower box
The closed roller frame formed, cabinet top are equipped with top cover, and the end of top cover is respectively equipped with new slurry inlet pulp hole 21 and mud follows
Annular distance 22；Lower box is divided into circulatory pool, the second sedimentation basin and the first sedimentation basin by partition 25, wherein two through-holes
29 are respectively arranged in 25 top of partition of cabinet axis two sides, and the height of two through-holes 29 is consistent, divide on the outer wall of circulatory pool
Slurry hole 23 and slurry outlet 24 She You not taken.
Specifically, removable mud pit provided in this embodiment, mud box body 20 is placed on car body 10, mud
Box body 20 is drum-type structure, can be around the axial direction rotation of its length direction, that is to say, that mud box body can not only
It realizes rotation, guarantees the stability of mud, while can also realize and move freely under the drive of car body 10.Cause
This, removable mud pit provided in this embodiment can be realized from the preparation of slurry manufacture factory and meet the mud of design requirement, then transports
It is transported to construction site, solves the limitation of on-site slurry preparation；In addition, due to using drum-type mud pit, by turning
The certain revolving speed of dynamic motor control, can make mud be uniformly mixed during transportation, to guarantee the stability of performance, make
Slurry transportation quickly, save manpower and to realize the commercialization of slurrying broken mud to the limitation of site requirements
Property.
Particularly, 20 upper rear of mud box body is set there are two entering to starch channel, respectively newly slurry inlet pulp hole 21 and mud
Circulation port 22, new inlet pulp hole 21 of starching are set at the top of the first sedimentation basin position (car body cephalad direction is front) rearward, and mud follows
Annular distance 22 is set at the top of the first sedimentation basin by front position；Wherein, newly slurry inlet pulp hole 21 is used for from slurry manufacture factory to construction
The new mud supplement at scene；Recycling of the circulating opening 22 for laitance and impurity in stake casing, realizes construction site mud
Circulation, meanwhile, in order to guarantee that laitance smoothly enters mud pit from stake casing, when carrying out laitance recycling, circulating opening 22 is needed
Closing is connected with hose to use.In addition in view of the recycling to laitance and impurity in stake casing, slurry hole 23 and slurry outlet 24 are taken
It is set on the circulatory pool outer wall of 20 front of cabinet.In order to be recycled to the laitance in stake casing, three ponds of mud pit
It is separated, and three horizontally arranged settings in pond, is used by partition 25 between (circulatory pool, the second sedimentation basin and the first sedimentation basin)
When, mud pit does not rotate, it remain stationary state, an only through-hole 29 on adjacent partition 25, and according to the flow path of mud,
Through-hole 29 between first pond and second pond (the first sedimentation basin and the second sedimentation basin) is located at 25 top of partition, and second
Through-hole 29 between a pond and third pond (the second sedimentation basin and circulatory pool) is located at the top of partition 25, but two logical
Hole 29 is staggeredly arranged, and is respectively arranged at the two sides (referring to fig. 4) of cabinet axis, so as to control the flow direction of mud, increases
Add mud to flow course, has the function that circulating mud contamination precipitation.
In the present embodiment, it is highly preferred that 20 top of cabinet and side are additionally provided with hollowed-out board 26,26 one end of hollowed-out board and top
Lid inner wall is fixedly connected.That is, during slurry transportation, because of the missing of mud property, to guarantee that mud property is stablized,
It is uniformly mixed, increases the mixing effect of mud during transportation so that mud property is stablized and hollow out is set on cabinet wall
Plate 26, so that drum-type cabinet is reinforced stirring in the course of rotation, to guarantee being sufficiently mixed for mud, performance is stablized.
In the present embodiment, it is highly preferred that in order to solve the sediment of mud accumulation, 20 tail end outer wall of cabinet is equipped with and opens
Enclosed circular glass door opening 27, convenient for the cleaning of mud dregs.
In the present embodiment, it is highly preferred that in order to control the air pressure in mud box body, outside the cabinet on the top of circulatory pool
Valve 28 is additionally provided on wall.
In the present embodiment, it is highly preferred that the quantity of slurry outlet 24 is 2,2 slurry outlets 24 are respectively arranged at circulatory pool
Two sides.In this way, any side at left and right sides of mud pit may be implemented to transport slurry into stake casing, without adjustment
The position of mud pit.
Certainly, due to the limitation of 20 self-capacity of car body 10 and cabinet, cause the mud reserves value of mud pit insufficient, and
Consider the circulation of mud and reduce the transport frequency of mud, can use needs turn hole stake casing to store slurry liquid around pile foundation.
Please continue to refer to Fig. 1 to Fig. 4, the present invention also provides the application method of aforementioned removable mud pit, the users
Method includes the following steps:
