Abstract
A prefabricated anti-leakage push pipe working open caisson is formed by sequentially overlapping and splicing a well base and at least two shafts from bottom to top, wherein the upper end of the well base is provided with a socket; the upper end of the shaft is provided with a socket, and the lower end of the shaft is provided with a socket which can be matched with the socket of the shaft seat and the shaft; at least two rubber ring grooves for placing sealing rings are arranged on the outer peripheral walls of the sockets of the well seat and the well shaft at intervals, so that when the well seat and the well shaft above the well seat or two adjacent well shafts are spliced, at least two rubber ring seals are arranged at each joint for sealing, and therefore the structure of the utility model is more reasonable and the sealing performance is good.
Description
Technical Field
The utility model relates to a prefabricated part for municipal engineering, in particular to an open caisson used for a working well for pulling a jacking pipe.
Background
It is known that the caisson used in civil engineering for the operation of pipe jacking is basically composed of a well base and a plurality of well bores, and the caisson is assembled to a desired depth by splicing the well base and the well bores one above the other. Currently, the leak-proof sealing is filled with cement mortar at the joint of the well seat and the upper well bore or between two adjacent well bores and the joint of the two well bores, the sealing mode is easy to leak water, and therefore the sealing performance of the current open caisson at the joint is poor. To this end, the applicant has made improvements.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a prefabricated leak-proof push pipe working open caisson which is more reasonable in structure and good in sealing property.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a prefabricated leak protection is drawn pipe work open caisson, is formed by from up the concatenation of lapping in proper order down by a well seat and two at least pit shafts, wherein:
a socket is arranged at the upper end of the well seat;
the upper end of the shaft is provided with a socket, and the lower end of the shaft is provided with a socket which can be matched with the socket of the shaft seat and the shaft;
and at least two rubber ring grooves for respectively placing sealing rings are arranged on the outer peripheral walls of the sockets of the well seat and the shaft at intervals.
In the improved scheme of the prefabricated leakage-proof push pipe working open caisson, the well base and the shaft are provided with grouting holes on the section of the socket between the two adjacent rubber ring grooves, and sealing materials are injected from the grouting holes to the joint.
In the improved scheme of the prefabricated leak-proof push pipe working open caisson, the sealing material is epoxy resin.
Compared with the prior art, the utility model has the beneficial effects that: 1) because the outer peripheral walls of the sockets of the well seat and the shaft are respectively provided with at least two rubber ring grooves for placing the sealing rings at intervals, when the well seat and the shaft above the well seat or two adjacent shafts are spliced, each joint is sealed by at least two rubber ring seals, so the structure of the utility model is more reasonable and the sealing performance is good; 2) in the preferred scheme, the well seat and the shaft are provided with grouting holes on the section of the insertion opening between the two adjacent rubber ring grooves, and sealing materials are injected from the grouting holes to the joints, so that the double sealing consisting of at least two sealing rings and the sealing materials is formed at each joint of the working open caisson, and the sealing performance is better.
The utility model is described in further detail below with reference to the following detailed description and accompanying drawings:

[ detailed description ] embodiments
The utility model relates to a prefabricated anti-leakage push pipe work open caisson which is formed by sequentially overlapping and splicing a well base 1 and at least two wellholes 2 from bottom to top as shown in figures 1 to 6, wherein:
the upper end of the well seat 1 is provided with a socket 11;
the upper end of the shaft 2 is provided with a socket 21, and the lower end is provided with a socket 22 which can be matched with the sockets 11 and 21 of the well seat 1 and the shaft 2;
at least two rubber ring grooves 4 for respectively placing the sealing rings 3 are arranged on the outer peripheral walls of the sockets 11 and 21 of the well seat 1 and the shaft 2 at intervals; when the well seat 1 is spliced with the upper well bore 2 or two adjacent well bores 2, at least two sealing rings 3 are arranged at each joint of the working open caisson for sealing, so that the structure of the utility model is more reasonable and the sealing performance is good.
In this embodiment, as a preferred embodiment, the well base 1 and the well shaft 2 are provided with grouting holes 5 on the sections of the sockets 11 and 21 between the two adjacent rubber ring grooves 4, and sealing materials (not shown in the figure) are injected from the grouting holes 5 to the joints, so that the working open caisson has double sealing consisting of at least two sealing rings 3 and the sealing materials at each joint, thereby achieving better sealing performance.
The sealing material is usually epoxy resin, but may be other sealing materials.
In the first and second embodiments, there are 2 well bores, and there are two rubber ring grooves 4 on each jack. In the first embodiment shown in fig. 1, the well base 1 is bottomed, and this construction method is suitable for the occasion of digging a pit first and then setting a working open caisson; in the second embodiment shown in fig. 4, the well base is not provided with a bottom seal, the construction method is suitable for the occasion of placing the open caisson while digging the pit, and the bottom seal is formed in the bottom of the well base after the open caisson is placed and the reinforced concrete is poured.
Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made herein without departing from the spirit and scope of the utility model as defined in the appended claims. Therefore, the detailed description of the embodiments of the present disclosure is to be construed as merely illustrative, and not limitative of the remainder of the disclosure, but rather to limit the scope of the disclosure to the full extent set forth in the appended claims.
