Description

Technical Field

[0001] The invention relates to the technical field of hydraulic engineering construction, and in particular to a one-time cast-formed ship lock chamber wall composite template and a construction method thereof. Background Art

[0002] The development of my country's water transport industry is ushering in a major historical opportunity, and the construction technology of ship locks has also entered a leap-forward development. The cross-section of the ship lock, which is cast with reinforced concrete, presents a regular trough structure. On the wall of the lock chamber, a floating bollard groove is vertically set, which plays a vital role in ensuring the safe berthing of passing ships.

[0003] In order to ensure that the floating bollard can achieve extremely high installation accuracy, the traditional floating bollard slot construction process often adopts the second-phase concrete pouring construction method. Before the second-phase concrete pouring construction is carried out, a series of complex and delicate preparations are essential. The construction workers need to carefully roughen the contact surface of the first-phase concrete. This process not only requires the construction workers to have superb skills, but also requires them to pay great patience and carefulness, because only in this way can the quality of subsequent concrete pouring be guaranteed, so that it can be closely combined with the first-phase concrete to form a solid and stable overall structure. At the same time, due to the particularity of the construction environment, it is also necessary to build a higher steel pipe support frame to firmly reinforce the template of the second-phase floating bollard slot. In this process, the construction workers need to accurately complete each construction step in the high-altitude working environment to ensure the firmness and stability of the support frame, and provide a solid foundation for the subsequent concrete pouring work.

[0004] However, although this traditional construction process can ensure that the verticality and clearance size of the roller guide groove meet the design requirements to a certain extent, it also has many drawbacks that are difficult to overcome. Since the internal space of the roller guide groove is extremely small and filled with a large number of tie bars, the concrete vibration work becomes extremely difficult. The vibrating rod is difficult to fully exert in the narrow space, and it is impossible to ensure that the concrete can be evenly and densely filled in every corner, resulting in uneven concrete quality and unsatisfactory overall appearance quality, with defects such as pitting and honeycomb. In addition, for construction workers, it is extremely inconvenient to operate in such a cramped and complex construction environment, which not only greatly reduces the construction efficiency, but also poses a great safety risk. During the process of pouring concrete, vibrating, and installing and removing formwork, workers may collide, fall, and other accidents if they are not careful, posing a serious threat to their own life safety.

[0028] The mooring post slot adopts an integrally detachable template, which reduces the use of brackets and the workload of setting up brackets. It is easy to install and disassemble. The template body can be welded and spliced ​​with cut leftover steel sheets, which can reduce the investment in labor and construction materials and save construction costs.

[0029] In the preferred embodiment, the structures of the first adjustable support rod 6, the second adjustable support rod 7, the third adjustable support rod 8 and the fourth adjustable support rod 9 are all cylindrical nuts with internal threads at both ends, and the two ends are respectively threadedly connected to the lower ends of the two long strip screws, and the protruding ends of the screws are provided with circular ring ends, and are rotatably connected to the template through the rotating seat 11; The fourth adjustable strut 9 is parallel to the first adjustable strut 6. One end of the second adjustable strut 7 and the third adjustable strut 8 are rotatably connected to the two ends of the rear end template 101 respectively, and the other end is rotatably connected to the fourth adjustable strut 9 and the first adjustable strut 6 at the middle point of the hinge on the two side molds 102 respectively.

[0030] In the preferred embodiment, the outer surface of the nut 701 of the second adjustable strut 7 is provided with a plurality of wrench grooves 702, the inner part of the wrench groove 702 is a circular groove 7021, and is connected to the outer surface of the nut 701 through a rectangular groove 7022 whose width is smaller than the diameter of the circular groove, and the upper end of the rectangular groove 7022 is also evenly provided with a plurality of connecting holes 7023 having the same diameter as the circular groove; The nut of the third adjustable support rod 8 and the wrench groove thereon are arranged in a mirror image with the second adjustable support rod 7 along the center line of the Ω-shaped combined template 1.

[0031] In the preferred embodiment, the wrench slot 702 is inclined along the tightening direction of the nut 701, and the angle is 5°~30°, and the projected arc length between the connecting hole 7023 at the lower end of one wrench slot 702 and the connecting hole 7023 at the upper end of an adjacent wrench slot 702 is equal to the projected arc length between two adjacent connecting holes 7023 on the same wrench slot 702.

The scissor structure makes it convenient for the front end to extend into the gate chamber from the relatively narrow front end opening of the Ω-shaped combined template 1, and the worker operating end adopts a long lever arm design to achieve the effect of labor-saving operation. At the same time, the moving distances of the two ends are symmetrical, and equal forces can be applied to the second adjustable support rod 7 and the third adjustable support rod 8 at the same time, achieving the effect of synchronous adjustment, so that the installation symmetry of the two sides of the template is accurate, or the effect of simultaneous demolding of both sides can be achieved during demolding, thereby improving the construction efficiency and demolding effect.

[0034] Since the front end movement distance of the scissors wrench 10 is opposite, a support rod nut with an opposite tightening direction is correspondingly set, and the wrench grooves 702 thereon are mirrored to each other. A plurality of "end-to-end" wrench grooves 702 are set to achieve the effect of equidistant wrench movement in a circle. The diameter of the lever rod 1003 is smaller than the width of the rectangular groove 7022, so that the lower end of the lever rod can have a certain inclination in the wrench groove 702, and the lower end ball head 1004 abuts against the surface of the circular groove 7021. The length of the lever rod 1003 is greater than the height of the sleeve 1002 to offset the height difference caused by the rotation of the nut, and the upper end ball head 1004 is used to limit the longitudinal movement distance of the lever rod 1003 to prevent it from falling off.
