The utility model has the characteristics of do benefit to construction, safe and reliable, economy and be suitable for, can wide application in tunnel construction field.
Description
Technical Field
The utility model relates to a tunnel construction field especially relates to a reaction frame that is used for shield structure machine to originate at little radius curve.
Background
In the prior shield construction, a shield starts on a straight line or a curve with a large radius, and left and right side upright posts of a starting reaction frame are symmetrically arranged. However, in a specific project, since the shield machine starts on a small-radius curve and a tunnel portal has a certain included angle, the stand column of the reaction frame on one side is unevenly stressed, the structure of the reaction frame is possibly damaged, and the project is delayed, so that a new working idea needs to be found in the project for reference.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of above-mentioned background art, provide a reaction frame that is used for shield structure machine to initiate at little radius curve, make it have do benefit to the characteristics of construction, safe and reliable, economy and applicability.
The utility model provides a pair of a reaction frame that is used for shield structure machine to originate at little radius curve, including reaction frame and along reaction frame both sides and bottom, be fixed in the built-in fitting of entrance to a cave with reaction frame, one side that reaction frame is close to little radius curve is equipped with the strengthening rib pole.
In the above technical scheme, the reaction frame is formed by connecting four h-steel rods, the h-steel rods are composed of first end plates arranged at two ends and connecting plates connected with the two first end plates, the reinforcing rib rods are U-shaped channel steel, the U-shaped channel steel is composed of second end plates arranged at two ends and rib plates connected with the two second end plates, and two sides of the rib plates are respectively connected with the first end plates in a welding mode at the same side.
In the technical scheme, the I-shaped steel rod connected with the reinforcing rib rod is provided with the embedded part which is simultaneously connected with the reinforcing rib rod and the I-shaped steel rod.
In the technical scheme, supporting pieces are uniformly distributed on the tops of the I-shaped steel rods positioned on the tops of the reaction frame frames, supporting rods are arranged on the tops of the supporting pieces, and embedded parts are uniformly distributed on the supporting rods.
The utility model is used for shield constructs the reaction frame that the machine was originated at little radius curve, has following beneficial effect: the method for widening one side of the reaction frame is adopted to ensure the smoothness of the initial start of the shield machine, 3 steel plates are added on the side face of the original I-shaped steel rod for welding, then the side face of the whole reaction frame after the steel plates are welded forms a firmer structure, and a firm integrated structure is formed with a tunnel portal through the embedded part. Compared with refitting the reaction frame again or other methods, the method greatly saves cost and time and can be used for reference of other similar items.
Drawings
Fig. 1 is a schematic structural view of a reaction frame for a shield tunneling machine to start in a small radius curve according to the present invention;
FIG. 2 is a structural cross-sectional view taken along line A-A of FIG. 1;

Detailed Description
The present invention will be described in further detail with reference to the following drawings and examples, but the examples should not be construed as limiting the present invention.
Referring to fig. 1, the utility model is used for the shield constructs the reaction frame that the machine originated at small radius curve, including reaction frame 1 and along 1 both sides of reaction frame and bottom, be fixed in the built-in fitting 2 of entrance to a cave with reaction frame 1, one side that reaction frame 1 is close to small radius curve is equipped with stiffener pole 3.
Referring to fig. 2, the reaction frame 1 is formed by connecting four h-steel rods 1.1, the h-steel rods 1.1 are composed of first end plates 1.1.1 arranged at two ends and connecting plates 1.1.2 connecting the two first end plates 1.1.1, referring to fig. 3, the reinforcing bar rods 3 are U-shaped channel steel, the U-shaped channel steel is composed of second end plates 3.1 arranged at two ends and rib plates 3.2 connecting the two second end plates 3.1, and two sides of the rib plates 3.2 are respectively welded with the same side edge of the first end plate 1.1.1.
Referring to fig. 1, an embedded part 2 connected with the reinforcing bar rod 3 and the i-shaped steel rod 1.1 is arranged on the i-shaped steel rod 1.1 connected with the reinforcing bar rod 3.
Support pieces 4 are uniformly distributed on the tops of I-shaped steel rods 1.1 located at the tops of the reaction frame frames 1, support rods 5 are arranged on the tops of the support pieces 4, and embedded parts 2 are uniformly distributed on the support rods 5.
The method of widening one side of the reaction frame 1 is adopted to ensure the smoothness of the initial initiation of the shield machine, 3 steel plates are added on the side surface of the original I-shaped steel rod 1.1 for welding, then the side surface of the whole reaction frame 1 after the steel plates are welded forms a firmer structure, and the side surface and a tunnel opening (not shown in the figure) form a firm integrated structure through the embedded part 2. Compared with refitting the reaction frame again or other methods, the method greatly saves cost and time.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
Those not described in detail in this specification are within the skill of the art.
