Description

TECHNICAL FIELD

[0001] The utility model relates to a tunnel construction technical field, in particular to a dry device for tunnel engineering construction. BACKGROUND

[0002] Tunnel engineering is the building constructed underground or underwater or in mountain, laying railway or building highway for motor vehicle to pass. Tunnel construction usually includes five steps: hole section and hole gate construction, tunnel excavation construction, tunnel initial support, tunnel waterproof layer construction, secondary lining construction. Secondary lining is the moulded concrete or reinforced concrete lining constructed in the inside of initial support in tunnel engineering construction, which forms composite lining with initial support.

[0003] In secondary lining construction, cement concrete structure layer has large humidity, which makes the humidity of air in tunnel large, not only affecting the hardening of concrete structure, but also affecting subsequent construction operation.

The dry device for tunnel engineering construction is compact in structure, simple in operation and convenient to move, and can effectively remove the humid gas in the tunnel.

[0005] The above-mentioned device has the following problems:

[0006] 1. The equipment is connected to an external air extraction device through a pipeline to extract the gas in the tunnel, dry it, and then send it into the tunnel through the pipeline to replace the gas with high humidity. When the tunnel is long, a long connecting pipe needs to be laid. The ventilation mode of the tunnel usually uses an air extractor to suck the tunnel gas through the top air duct, and the hole directly sucks in fresh air. The amount of air entering the hole is larger than the amount of gas entering the pump, the efficiency is high, and the air outside the tunnel is drier than the air inside the tunnel, so there is no need to consume energy for secondary drying.

[0007] 2. The dry gas sent into the tunnel will soon mix with the surrounding humid gas and spread to various places in the tunnel, making it difficult to efficiently dry the concrete structure during construction. To solve the above problems, a dry device for tunnel engineering construction is designed. UTILITY MODEL CONTENTS
