Detailed Description

In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings.

As shown in fig. 1-4, the steel form tail plate of the concrete pipe pile comprises a tail plate main body 1 and a rubber plug. Wherein, the tail plate main body 1 can be connected with one end of an opening of the steel mould 2, an inner hole 3 of the tail plate main body 1 can be communicated with the inside and the outside of the steel mould 2, the pumping pipe is inserted into the steel mould 2 through the inner hole 3 of the tail plate main body 1 in the prior art, therefore, the scheme is provided with a rubber plug 4 at the position of the tail plate main body 1, the rubber plug 4 can be connected with the position of the inner hole 3 of the tail plate main body 1, the rubber plug 4 is provided with a cannula port 5 corresponding to the inner hole 3, the cannula port 5 can be opened when being inserted into an object, the cannula port 5 can be understood as having elasticity, the size of the cannula port 5 can be changed after being extruded by the object, when the object is the pumping pipe for conveying concrete slurry, the cannula port 5 of the rubber plug 4 can always keep a contact state with the outer wall of the pumping pipe, the clearance around the pumping pipe inserted into the steel mould, when outwards extracting, the intubate mouth 5 that has elastic rubber end cap 4 can stay the slurry that the pump delivery pipe goes out the thick liquid position and carries in steel mould 2, solves the pump delivery pipe and outwards takes out the problem of concrete slurry when extracting.

As shown in fig. 2, in order to improve the radial dimension variation of the cannula port 5 to better adapt to the type of the pumping tube, the rubber plug 4 is provided with a plurality of cutting seams 6 along the circumferential direction of the cannula port 5, a single cutting seam 6 is arranged along the radial direction of the cannula port 5, the cutting seam 6 penetrates through the rubber plug 4, the arrangement of the cutting seams 6 is equivalent to the division of the vicinity of the cannula port 5 of the rubber plug 4, after the pumping tube is inserted from the cannula port 5, the cannula port 5 receives the radial expansion force, and the divided cannula port 5 is equivalent to the reduction of the expansion force of the interaction between the pumping tube and the rubber plug 4, so that the self-adaptive capacity of the cannula port 5 is increased, and the insertion and extraction of the pumping tube are easier. When the cannula mouth 5 is divided, the radial dimension variation of the cannula mouth 5 is increased, the deformation capability is improved, so that when the pumping tube passes through the cannula mouth 5, the radial dimension of the cannula mouth 5 is increased, the radial dimension of the cannula mouth 5 has an upper limit, the minimum radial dimension is the dimension of the cannula mouth 5 in a normal state (i.e. when the cannula mouth is not acted by external force), and the radial dimension of the cannula mouth 5 is limited according to the principle: the radial dimension of the cannula mouth 5 has a minimum value in the non-compressed state and a maximum value in the compressed state; the radial dimension of the pumping tube is greater than the minimum value of the radial dimension of the cannula nozzle 5 and less than or equal to the maximum value of the radial dimension of the cannula nozzle 5. When the radial dimension of the pumping tube is greater than the maximum value of the radial dimension of the cannula port 5, the pumping tube is not insertable from the cannula port 5.

For the convenience of the connection and fixation of the tail plate main body 1 and the steel die 2, the tail plate main body 1 is provided with a plurality of first bolt holes 7, and the tail plate main body 1 passes through the first bolt holes 7 through bolts and is detachably connected with the steel die 2. The first bolt holes 7 of the tail plate main body 1 can be uniformly distributed along the axial direction, and the bolt connection stability is improved. Meanwhile, a plurality of exhaust holes 12 are formed in the upper half circumference of the tail plate main body 1 and used for discharging air inside the steel die 2 outwards, and smooth injection of concrete slurry is guaranteed.

Rubber end cap 4 is equipped with a plurality of second bolt holes 8, and rubber end cap 4 passes second bolt hole 8 through the bolt and can dismantle with tailboard main part 1 and link to each other. The second bolt holes 8 of the rubber plugs 4 can be uniformly distributed along the axial direction, so that the bolt connection stability is improved.

The steel mould subassembly of concrete pipe pile includes: a steel die 2 having one end opened; and a steel form tail according to any one of claims 1 to 4, the tail body 1 of the steel form tail being capable of being attached to an open end of a steel form 2. After tailboard main part 1 and steel mould 2 are connected, when concrete slurry pressure is big in the steel mould 2, the hookup location of concrete slurry extrusion steel mould 2 and tailboard main part 1, the hookup location to tailboard main part 1 and steel mould 2 produces the extrusion force that lasts, in order to improve the joint strength and the leakproofness of tailboard main part 1 and steel mould 2, avoid steel mould 2 and the not hard up hourglass thick liquid of the 1 junction of tailboard main part, the sealing member has been adopted and has been consolidated connection to tailboard main part 1 and steel mould 2, the joint strength of tailboard main part 1 and steel mould 2 has effectively been improved, guarantee good leakproofness.

The steel mould assembly further comprises a sealing element, and the tail plate main body 1 can be connected with the steel mould 2 in a sealing mode through the sealing element.

Specifically, the sealing member is including setting up the tailboard baffle 9 in steel mould 2 opening one end, and tailboard baffle 9 is equipped with the recess 10 of establishing with tailboard main part 1 looks card. The design of a tail plate baffle plate 9 is adopted, one side of the tail plate baffle plate 9 is connected with a steel die 2, the other side of the tail plate baffle plate 9 is connected with a tail plate main body 1, a groove 10 specially used for clamping the tail plate main body 1 is arranged on the tail plate baffle plate 9, the tail plate main body 1 is matched with the groove 10 of the tail plate baffle plate 9 in design, and the tail plate baffle plate 9 mainly plays a role in positioning and clamping the tail plate main body 1 and is an important stressed part; the tail plate baffle 9 can be provided with a cutting seam which is divided into an upper semicircle and a lower semicircle, thereby being convenient to install and use.

As shown in fig. 4, in order to facilitate the clamping connection between the tail plate body 1 and the groove 10 of the tail plate baffle 9, a groove 11 is formed on the groove 10 at a side away from the steel die 2, and the groove 11 is provided with a bell mouth extending outwards along the groove 10. The bell mouth design of groove 11 makes the butt joint card that the tailboard main part 1 can be quick accurate go into recess 10, has simplified the operation.
