Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, and particularly relates to a control device for the cutting direction of a concrete pipeline saw. Background Technique
[0002] The retaining structure, groundwater control, environmental protection and other measures required to ensure the safety and stability of the underground space formed by excavation downward from the ground during the construction of the underground structure are called foundation pit engineering.
[0003] Foundation pit engineering is a systematic project integrating geological engineering, geotechnical engineering, structural engineering and geotechnical testing technology. Its main contents include: engineering investigation, design and construction of retaining structures, earth excavation and backfilling, groundwater control, information-based construction and surrounding environmental protection, etc. The simplest and most economical method for foundation pit construction is to excavate with a large slope, but it is often restricted by site conditions and surrounding environments. Therefore, it is necessary to design a support system to ensure the smooth progress of construction and better protect the surrounding environment.
[0004] Foundation pit engineering has relatively high risks. The foundation pit support system is generally a temporary measure, and its safety reserves in terms of load, strength, deformation, anti-seepage, durability, etc. are relatively small.
[0005] Foundation pit engineering has obvious regional characteristics. Different regions have different engineering geological and hydrogeological conditions, and there may be significant differences even in the same city.
[0006] Foundation pit engineering has obvious environmental protection characteristics. The construction of foundation pit engineering will cause changes in the surrounding groundwater level and stress field, resulting in the deformation of the surrounding soil mass and affecting the adjacent environment.
[0007] The theory of foundation pit engineering is not yet perfect. Foundation pit engineering is a science that intersects geotechnics, structure and construction, and is affected by various complex factors. Its earth pressure theory, foundation pit design and calculation theory, etc. still need to be further developed.
[0008] Foundation pit engineering has strong individual characteristics. The diversity of geological conditions in the area where the foundation pit is located, the complexity of the surrounding environment of the foundation pit, the diversity of the foundation pit shape, and the diversity of the foundation pit support form determine that foundation pit engineering has obvious individuality.
[0009] Generally, drainage pipes are laid in the foundation pit. When cutting drainage pipes in deep foundation pits or narrow working pits of municipal foundation pit engineering, the traditional process uses manual breaking, which is easy to disturb adjacent drainage pipes or cause cracks in the pipes, reducing the service life of the drainage pipes. Content of the Utility Model
[0010] The purpose of the present utility model is to overcome the problems raised in the above-mentioned background technology, and provides a control device for the cutting direction of a concrete pipeline saw. This device is beneficial to be installed on the drainage pipelines in deep foundation pits and narrow working pits. The cutting angle and cutting direction can be easily adjusted according to the on-site requirements. It solves the problem of different cutting angles and cutting directions at the same position, and can rotate the direction to effectively improve the construction efficiency.
[0011] The purpose of the present utility model is mainly achieved through the following technical solutions:
[0012] A device for controlling the cutting direction of a concrete pipeline saw, comprising a base. A vertical support rod is arranged on the base. A clamping seat is sleeved on the outer wall of the vertical support rod. A horizontal support rod is arranged on the clamping seat. Two clamping seats are sleeved on the horizontal support rod. The clamping seat is located between the clamping seats. Horizontal seats are arranged on the clamping seats. Guide frames are arranged on the horizontal seats. Pulleys are installed on the guide frames, and the pulleys can rotate along their own axes. Through holes are arranged on both the horizontal seats and the clamping seats, and the through holes are located below the pulleys. Currently, when cutting drainage pipes in deep foundation pits or narrow working pits of municipal foundation pit projects, the traditional process uses manual breaking, which is likely to disturb adjacent drainage pipes or cause cracks in the pipes, reducing the service life of the drainage pipes. Construction workers have also thought about using mechanical equipment for operation, but the existing mechanical equipment cannot be operated in deep foundation pits or narrow working pits, and the cutting direction and angle cannot be controlled, not meeting the construction requirements. To solve the above problems, this solution designs a device for controlling the cutting direction of a concrete pipeline saw, comprising a base. The base is used to support the device and is in contact with the outer wall of the pipe. A vertical support rod is arranged on the base. A clamping seat is sleeved on the outer wall of the vertical support rod. A horizontal support rod is arranged on the clamping seat. Two clamping seats are sleeved on the horizontal support rod.

Pulleys are installed on the guide frames, and the pulleys can rotate along their own axes. Through holes are arranged on both the horizontal seats and the clamping seats, and the through holes are located below the pulleys. A diamond wire saw is sleeved on the pulley. The diamond wire saw is made by kneading high-strength diamond into a wire saw. One end of the diamond wire saw passes through the pulley group for guiding and circular motion to reduce the friction resistance of the wire saw, and the other end is in reliable contact with the gear of the output power device. The power device rotates at a high speed to drive the annular diamond wire saw to rotate, thereby cutting the concrete structure to make it meet the cutting direction. The power device is an existing device, which can drive the diamond wire saw to work and maintain the cutting efficiency. The horizontal support rod and the vertical support rod are perpendicularly arranged. One pulley is arranged on each of the two clamping seats. In this way, the diamond wire saw can be sleeved on the concrete pipe to be cut and then on the pulley to form a tensioned cut. It can be correspondingly installed at the position of the concrete pipe according to different cutting angles and directions for cutting, which is beneficial for installation on drainage pipes in deep foundation pits and narrow working pits. The cutting angle and cutting direction can be easily adjusted according to the on-site requirements, solving the problem of different cutting angles and cutting directions at the same part. The direction can be rotated to effectively improve the construction efficiency.
[0013] Further, a guide groove is formed by the concave inner surface of the top surface of the base, and the guide groove penetrates the base. A gasket is arranged on the base. A bolt is arranged in the gasket. The bolt passes through the gasket and inserts into the guide groove and can move in the guide groove. The setting of the guide groove is to facilitate the bolt to fix the base on the concrete pipe, so as to reduce the shaking of the device during cutting and make the cutting more accurate.
[0014] Further, in order to make the installation more secure during cutting, legs are installed on the side wall of the base. The legs are perpendicularly fixed to the side wall of the base and are symmetrically arranged along the center line of the base. Locking bolts are provided on the legs. By inserting the locking bolts into the concrete pipe, multi-point positioning and fixation are achieved, making the cutting more accurate.
[0015] Further, openings are provided on the side walls of the horizontal base and the clamping base, and the openings penetrate through the top and bottom of the horizontal base and the clamping base respectively and communicate with the through holes. The provided openings facilitate the entry of the diamond wire saw into the through holes.
[0016] In summary, compared with the prior art, the present utility model has the following beneficial effects: This device is beneficial to be installed on the drainage pipes in deep foundation pits and narrow working pits. The cutting angle and cutting direction can be easily adjusted according to the on-site requirements, solving the problem of different cutting angles and cutting directions at the same position. It can rotate the direction to effectively improve the construction efficiency. The diamond wire saw is used to cut the drainage pipes, efficiently positioning the cutting position, with little disturbance during the cutting process, and improving the cutting quality guarantee of the pipes.
