Description

Rail sliding formwork system for concrete dam overflow surface inclined plane section

Technical Field

The utility model relates to a dam construction slipform technical field provides a there is rail slipform system of concrete dam overflow face inclined plane section very much.

Background

The overflow surface of the concrete dam at least comprises an inclined surface section and an arc section, a slip form is usually adopted for pouring concrete in the construction process of the inclined surface section, the current slip form system is mainly divided into a rail slip form and a trackless slip form, and the slip form needs to bear the floating force of the concrete in the operation process, so that the stability of the slip form in the operation process is low, and the concrete pouring effect of the overflow surface is influenced.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a there is rail slipform system of concrete dam overflow surface inclined plane section.

The utility model discloses a realize like this, a there is rail slipform system of concrete dam overflow face inclined plane section, including the slipform, the slipform includes carriage, platform and two tracks of plastering, and the platform of plastering is connected at the back of carriage, sets up the panel below the carriage, and two tracks are fixed in the both sides of overflow face inclined plane section, and the both ends of carriage are provided with the gyro wheel, and the gyro wheel at both ends matches respectively in two tracks.

Preferably, the device further comprises a guide wall, two sides of the guide wall are arranged on two sides of the inclined plane section of the overflow surface respectively, the dowel bars are embedded in the guide wall, and the two rails are fixedly connected with the exposed portions of the dowel bars respectively.

Further preferably, the concrete dam construction device further comprises three winches which are pre-embedded at the top end of the concrete dam through ground anchors and connected with the middle and two ends of the sliding frame through 3 steel wire ropes.

Further preferably, the rollers are arranged in groups of 4 rollers and 2 rollers and are respectively arranged at the front end and the rear end of two sides of the sliding frame.

Further preferably, the sliding frame has a cross-sectional dimension of 800 x 900mm, and the troweling platform has a width of 1.3 m.

Compared with the prior art, the utility model has the advantages of:

carry on spacingly through the track to the slipform, carry out whole support through the gyro wheel to the carriage, increase the dead weight through increasing the platform of plastering to increase the stability of slipform, improve the quality of pouring of dam overflow face.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, 2, 3 and 4, the utility model provides a there is rail slipform system of concrete dam overflow face inclined plane section, including the slipform, the slipform includes carriage 1, platform 2 and two tracks 3 of plastering, and platform 2 of plastering is connected at the back of carriage 1, sets up the panel below carriage 1, and two tracks 3 fix in the both sides of overflow face inclined plane section, and the both ends of carriage 1 are provided with gyro wheel 4, and the gyro wheel 4 at both ends matches respectively in two tracks 3.

When the slip form system is used for pouring construction of the dam overflow surface inclined plane section, the two rails 3 are installed firstly, after the rails 3 are installed and adjusted, the sliding frame 1 and the plastering platform are installed, and concrete can be poured after acceptance inspection is qualified.

In order to facilitate installation of the two rails 3, as an improvement, referring to fig. 2, the rail structure further includes a guide wall 5, the guide wall 5 is provided with two sides respectively arranged at two sides of the inclined section of the overflow surface, the dowel bars 6 are embedded in the guide wall 5, and the two rails 3 are respectively and fixedly connected with the exposed portions of the dowel bars 6.

Because carriage 1 needs the traction system, consequently, this novel slipform system that provides still includes hoist engine 7, refer to fig. 5 and fig. 6, hoist engine 7 through the ground anchor pre-buried on the top of concrete dam, and hoist engine 7 is equipped with threely, respectively through 3 wire ropes 8 with the centre and the both ends of carriage 1 are connected.

Because two tracks 3 that carriage 1 needs move on, in order to improve the stability of whole support body operation, gyro wheel 4 is equipped with 4, and 2 are a set of, establish respectively the front end and the rear end of 1 both sides of carriage.

Preferably, the sliding frame 1 has a cross-section dimension of 800 x 900mm, and the troweling platform 2 has a width of 1.3 m.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
