Abstract

The invention relates to an automatic pipe jacking device with an adjustable angle, which comprises a reaction frame, a bottom plate, a rectangular pipe jacking hole and a pipe jacking machine, wherein a first wedge body is arranged between a track of the pipe jacking machine and the bottom plate, the horizontal angle of the first wedge body is controlled by a first automatic jack, a second wedge body is arranged between the pipe jacking machine and the reaction frame, and the vertical angle of the second wedge body is controlled by a second automatic jack, so that the hole jacking stage of the head of the pipe jacking machine is parallel to the axis of an inclination angle. The invention is used for reforming the pipe-jacking project, reforming the pipe-jacking backrest, the guide rail system and the tunnel opening lining wall, ensuring that the pipe jacking goes out of the tunnel according to the inclination angle required by the actual project, better controlling the jacking direction so as to better adapt to the pipe-jacking project and further reducing the economic cost.

Description

Automatic pipe jacking device with adjustable angle

Technical Field

The invention relates to a rectangular pipe jacking construction device, in particular to an automatic pipe jacking device with an adjustable angle.

Background

The pipe jacking method is suitable for construction of a conventional underground communication channel, but the communication channel with the inclination angle is caused by objective reasons (factors such as avoidance of underground obstacles), and the pipe jacking method needs a pipe jacking machine to carry out jacking operation, so that jacking construction of rectangular jacking pipes with the inclination angle is difficult to realize, and a targeted jacking device is needed to solve the problem.

Disclosure of Invention

The invention aims to provide an automatic pipe jacking device with an adjustable angle, and provides a specific and effective construction device aiming at solving the problem that the pipe jacking with an inclined angle is difficult to jack in construction without a proper construction method at present.

In order to realize the construction purpose, the invention adopts the following scheme:

the utility model provides an automatic push bench of adjustable angle, includes reaction frame, bottom plate, rectangle push pipe play entrance to a cave, push bench, set up wedge one between the track of push bench and the bottom plate, wedge one controls horizontal angle through automatic jack, set up wedge two between push bench and the reaction frame, two control vertical angle of automatic jack are passed through to wedge two, make the ejecting entrance to a cave stage of aircraft nose of push bench, be parallel with the inclination axis promptly.

And furthermore, the first automatic jack and the second automatic jack are connected with a control computer and used for automatically adjusting the in-out angle of the jacking pipe according to the out-of-hole angle of the jacking pipe required by the actual engineering.

Furthermore, a lining wall is arranged at the rectangular pipe jacking exit, and a third jack is arranged inside the lining wall and used for correspondingly adjusting according to the horizontal angle of the first wedge and the vertical angle of the second wedge so as to ensure that the pipe jacking machine head is vertical to the lining wall at the exit, so that the lining wall plays a role of a hoop, and the pipe jacking machine and the pipe joints can be driven according to the designed inclination angle to meet the effect that the angle of the pipe jacking base can be automatically adjusted.

Compared with the prior art, the invention has the beneficial effects that:

1. the jacking construction method can effectively solve jacking construction of the jacking pipe according to any angle, is clear in stress, ensures jacking precision, and can better ensure construction quality.

2. The construction process formed by the invention is a construction measure which can be relatively quick and convenient, and has a wide application range.

Detailed Description

The invention is further illustrated with reference to the following figures and specific examples. These examples are given solely for the purpose of illustration and are not intended to limit the scope of the invention, which is to be given the full breadth of the present disclosure, and any variations or modifications within the skill of the art after reading the teachings herein, may be made, and such equivalents are intended to fall within the scope of the invention as defined in the claims appended hereto.

The embodiment provides a thrustor of rectangular jacking pipe with inclination angle, which specifically comprises the following steps:

as shown in fig. 1 and 2, firstly, a first wedge 1 is arranged between a track of a push bench 7 and a bottom plate, the horizontal angle of the first wedge is controlled by an automatic first jack 4, a second wedge 2 is arranged between a pushing device and a reaction frame, and the vertical angle of the second wedge is controlled by an automatic second jack 5, so that a rectangular push bench head is pushed out of a hole opening stage, namely is parallel to an inclination axis; and a jack III 6 is arranged in the inner lining wall 3 of the hole opening, and the corresponding adjustment is required according to the change so as to ensure that the pipe jacking machine head is vertical to the lining wall, and the lining wall plays a role of a hoop at the moment, so that the pipe jacking machine 7 and the pipe joint 8 can be tunneled according to the inclination angle i, and the automatic angle adjustment function of the pipe jacking base can be met.

Further, the horizontal angle of the arranged wedge body I1 can be controlled through an automatic jack I, and the vertical angle of the arranged wedge body II 2 is controlled through an automatic jack II 5. The first jack 4 and the second jack 5 can be connected with a computer according to the outlet angle of the jacking pipe required by the actual engineering, and the inlet and outlet angles of the jacking pipe can be automatically adjusted.

Further, an opening lining wall 3 is additionally arranged at the rectangular top pipe outlet, a jack III 6 is arranged inside the opening lining wall 3, the top pipe machine head is ensured to be vertical to the lining wall by adjusting the jack III 6, the lining wall plays a hoop role at the moment, a top pipe machine and a pipe section are driven according to the inclination angle i, and meanwhile, the lining wall can also prevent soil outside the pit and underground water from entering the working well.

The jacking construction method can effectively solve jacking construction of the jacking pipe according to any angle, is clear in stress, ensures jacking precision, and can better ensure construction quality. Meanwhile, the construction process is quick and convenient, and the application range is wide.
