Problems solved by technology

However, the structure of the device is complicated and the manufacture is cumbersome. One grouter can only grout one hole, and the cost is high; the material of the device is steel pipe, which cannot be re-drilled for secondary grouting; the reinforcement range of the grouter is limited. Unable to achieve adequate reinforcement of formations at different depths

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] A forward-type localized double-fluid grouting device, mainly composed of an auxiliary sleeve 12, a PVC grouting pipe, and a sealing grouting port 11. Wherein, the sealing grouting port 11 includes a grouting port 1 , a steel pipe 4 and a flange 2 connected in sequence.

[0041] The auxiliary casing is welded by the flange 2 and the steel casing 3, and its inner diameter is larger than the outer diameter of the PVC grouting pipe. The PVC grouting pipe is composed of a PVC pipe 6, a PVC pipe interface 7 and a grout stop cap 10, and the PVC pipe 6 and the steel pipe 4 are connected through a conversion interface 5. Plum blossom-shaped slurry outlet holes 8 are arranged on the PVC pipe 6 . The auxiliary casing 12 and the sealing grouting port 11 are connected through the flange 2 to realize sealing and shallow grouting. After the sealing grouting ...

Abstract

The invention discloses an advancing type localized double-liquid grouting device and a construction method. The device comprises a hole sealing grouting opening, an auxiliary sleeve and a grouting pipe. The grouting pipe is detachably connected to the hole sealing grouting opening. The grouting pipe with the hole sealing grouting opening is inserted in the auxiliary sleeve. The auxiliary sleeve is connected with the hole sealing grouting opening through a flange. The length of the grouting pipe is larger than that of the auxiliary sleeve so that deep localized grouting can be achieved. The advancing type localized double-liquid grouting device and the construction method have the advantages that the grouting pipe is simple in structure and suitable for being manufactured on site; the grouting device and the technological process are simple, and operation is easy and convenient; the price of PVC pipes is relatively low and construction cost is greatly saved; domain controlled grouting can be achieved, it is ensured that a stratum is uniformly reinforced, no blind point exits, and disasters are avoided; grouting can be repeatedly conducted, point selecting and hole opening are prevented from being conducted again, the construction period is shortened, and economic benefits are high; the application range is wide, and the advancing type localized double-liquid grouting device and the construction method are suitable for all engineering type soft stratums needing to be reinforced.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering, and in particular relates to a forward-type localized double-fluid grouting device and a construction method. Background technique [0002] Construction of shallow tunnels in soft sandy soil often results in stratum loss or even collapse due to excavation, which endangers the safety of construction personnel and equipment, and the excessive surface subsidence caused by stratum loss causes damage to the surrounding environment and brings great harm to residents. Normal production and life have been seriously affected. In order to ensure construction safety and reduce the impact of construction on the environment, the grouting reinforcement method is often used at home and abroad to pre-reinforce the ground. [0003] In traditional grouting reinforcement, the diffusion of grout in the formation is random and dispersed, and it is difficult to realize controlled area grouting, and the loss of...
