Embodiment 1

[0040] Embodiment one, with reference to figure 1 , is a municipal road pipe jacking construction safety equipment disclosed by the present invention, including a base 1, a sliding seat 2 slidably installed on the base 1, a bottom plate 3 fixed on the end of the base 1, and two hydraulic pressure points installed on the bottom plate 3. Cylinder 4.

[0041] refer to figure 1 , figure 2 Ejector 5 is installed on the sliding seat 2, the outer fixed sleeve of the movable rod of the hydraulic cylinder 4 is provided with a guide sleeve 41, the two sides of the sliding seat 2 are provided with a connecting sleeve 21, and the connecting sleeve 21 is provided with a passage for the guiding sleeve 41 to pass through. Through holes, the guide sleeve 41 is formed with three limit pieces arranged along its length direction. The limit pieces include two limit blocks 42, and a card slot 43 is formed between the limit blocks 42, and the connecting sleeve 21 is movable. There is a clamping...

Embodiment 2

[0047] Embodiment 2, the present invention discloses a construction method of pipe jacking safety equipment on municipal roads, including the following steps:

[0048] Step 1. Place the excavated jacking pipe on the base 1. The end of the jacking pipe and the round platform 51 on the ejector 5 cooperate with each other. The guide sleeves 41 are located on both sides of the jacking pipe for guidance, and the sliding seat 2 pushes the jacking pipe against it. tight;

[0049] Step 2, the hydraulic cylinder 4 works to make the guide sleeve 41 slide in the through hole, the drive motor 28 works to make the block 26 move down and act on a slot 43 close to the hydraulic cylinder 4, and the hydraulic cylinder 4 enters the extended state Make the sliding seat 2 slide, push the jacking pipe to the designated position, and the guide sleeve 41 continues to play the role of protection and guidance during the pushing process;

[0050] Step 3: The drive motor 28 rotates in the opposite dire...

Abstract

The invention relates to a municipal road pipe jacking construction safety equipment, which comprises a base, a sliding seat slidably installed on the base, a bottom plate arranged at the end of the base, and two hydraulic cylinders installed on the bottom plate. A guide sleeve is fixed on the outside of the movable rod of the hydraulic cylinder, and connecting sleeves are provided on both sides of the sliding seat. A through hole for the guide sleeve to pass is opened on the connecting sleeve, and three limiters arranged along its length are formed on the guide sleeve. The position piece, the limit piece includes two limit blocks, a card slot is formed between the limit blocks, a card block that matches the card slot is movably installed in the connecting sleeve, and a drive that drives the card block to move vertically is provided in the connecting sleeve. pieces. The invention has the effect of effectively guiding the pipe jacking during construction, and is convenient for the construction pipe jacking to better enter the soil.

Description

technical field [0001] The invention relates to the technical field of pipe jacking construction, in particular to a safety device for pipe jacking construction on municipal roads and a construction method thereof. Background technique [0002] At present, pipe jacking construction is a non-excavation construction method, which can realize pipeline burial under the premise of no excavation or less excavation. It uses the jacking force generated by jacking equipment in the working well to overcome the tension between the pipeline and the surrounding area. The friction of the soil pushes the pipeline into the soil according to the designed slope and direction, and transports the soil away. After one section of pipe has been jacked into the soil layer, the second section of pipe continues to be jacked. The principle is to push the tool pipe or roadheader through the soil from the working well with the help of the thrust of the main jacking cylinder, the pipe room, and the relay...
