The device body 1 is arranged on the surface of the horizontal section beam 4 and is detachably connected thereto. In order to be able to move to the corresponding position when hoisting horizontal pipes in different positions, the horizontal section beam 4 is arranged on multiple longitudinal supports. The longitudinal supports can play the role of erecting and fixing the horizontal section beam 4 to maintain the stability of the horizontal section beam 4, and multiple longitudinal supports are installed on the hardened ground for erecting the horizontal section beam 4 It is assumed that a capping beam is arranged above the retaining wall, and a crown beam is arranged between the retaining wall and the ground-connected wall. Multiple groups of cross arms are arranged on the ground-connected wall and the retaining wall. A vertical cross beam is fixedly installed on each group of cross arms. The length of the cross arm above the crown beam should be equal to the sum of the length of the cross arm below the crown beam and the width of the crown beam. The cross arm can play a role in erecting and fixing the vertical cross beam, and each diagonal arm can support the cross arm to improve the supporting strength of the cross arm. Secondly, the cross arm, the diagonal arm and the wall form a triangular structure, which can improve the strength. The end point of the cross arm above the crown beam should be at the same position as the end point of the cross arm below the crown beam. Vertical plane, the number of each group of cross arms is multiple, the end points of the cross arms located on the side walls of the foundation pit should all be in the same vertical plane, and an inclined arm is fixedly installed below the cross arm, the inclined arm located at the retaining wall is installed on the retaining wall, and the inclined arm located on the ground-connected wall is installed on the ground-connected wall. A pulley 2 is fixed on the end point on one side of the device body 1, and the pulley 2 is used to replace manpower to lift the horizontal pipe section, thereby simplifying the construction process and improving construction efficiency. The pulley 2 is located above the inside of the foundation pit, and a rope 3 lowered to the bottom of the foundation pit is wound around the pulley 2, one end of the rope 3 connected to the weight is connected to the horizontal pipe, and one end of the horizontal pipe is bent and passed through It is fixed by a fixing piece. At this time, the bending point of the horizontal pipe can be used as the lifting point of the rope 3 for lifting the horizontal pipe. The length of the rope 3 should be greater than the depth of the foundation pit. An insulation layer is arranged outside the horizontal pipe for protection. A weight is fixed at one end of the rope 3 extending into the bottom of the foundation pit. The weight can facilitate the rope to be lowered to the bottom of the foundation pit. A device bracket 5 is arranged below the device body 1. The device bracket 5 is placed above the retaining wall or hardened ground. The device body 1 can be supported by the device bracket 5, so as to maintain the stability of the device body 1. The height of the device bracket 5 should be equal to the sum of the longitudinal support height and the height of the horizontal section beam 4. Example

[0022] On the basis of Example 1, Figure 4As shown, the device body 1 is arranged on the surface of the horizontal section beam 4 and is detachably connected thereto, so that it can be moved to the corresponding position when hoisting horizontal pipes in different positions; the horizontal section beam 4 is arranged on multiple longitudinal supports, and multiple longitudinal supports are installed on the hardened ground for erecting the horizontal section beam 4, and a top beam is also arranged above the ground-connected wall, and the ground-connected wall is provided with multiple groups of cross arms, each group of cross arms is fixedly installed with a vertical section beam, and the number of each group of cross arms is multiple, and an oblique arm is fixedly installed under the cross arm, and the oblique arm is installed on the ground-connected wall, and the end point on one side of the device body 1 A pulley 2 is fixed on it, and the pulley 2 is located above the inside of the foundation pit, and a rope 3 is wound on the pulley 2 and lowered to the bottom of the foundation pit. One end of the rope 3 connected to the weight is connected to the horizontal pipe, and one end of the horizontal pipe is bent and fixed by a fixing piece. At this time, the bending point of the horizontal pipe can be used as a lifting point of the rope 3 for lifting the horizontal pipe.

[0023] The working principle of the utility model is as follows: before using the horizontal pipe climbing device of the deep foundation pit ground source heat pump system to lift the horizontal pipe, a horizontal pipe section used to climb the side wall of the foundation pit should be covered with an insulation layer. After covering the horizontal pipe section with the insulation layer, the horizontal pipe section is ready to be lifted to one end of the edge of the foundation pit and folded back to a certain length, fixed with a fixing piece, and after folding back to a certain length and fixing at the end point of the horizontal pipe, the pulley 2 located above the foundation pit lowers the rope 3 through the gaps between each vertical section beam and the side wall of the foundation pit to the bottom of the foundation pit under the action of a heavy object, and then connects with the horizontal pipe head. After the rope 3 is connected with the horizontal pipe head, the horizontal pipe is lifted to the top of the foundation pit by pulling the rope 3 in a horizontal state above the foundation pit. After the horizontal pipe section is lifted to the top of the foundation pit by the rope 3, the horizontal pipe section is fixed to the horizontal section beam 4. When lifting horizontal pipes at different positions, the device should be moved to the corresponding position in advance.

[0024] After all horizontal pipes are lifted, people are then lifted to the height of the vertical beams on the side walls of the foundation pit by means of a crane or other means, and the horizontal pipe sections are further fixed. After all horizontal pipe sections are lifted to the top of the foundation pit and fixed to the horizontal beams 4 (such as Figure 5 ), trim and organize all pipe sections, and build a temporary material yard (such as Figure 6 ) is used for finished product protection of horizontal pipe sections and is removed after the horizontal pipe sections are connected to the manifold.
